SAFETY FIRSTDO'S AND DON'TS
If this fireplace is not properly installed, a house fire may
result. For your safety, follow the installation directions.
Contact local building or fire officials about restrictions
and installation requirements in your area.
NOTE: We strongly recommend installers be WETT or
WHERF certified.
To ANYONE using this fireplace:
These DO’s and DO NOT’s are for your safety.
1. DO read this instruction manual before lighting yourfirst fire.
2. DO read the section MOVING THE DELTA before
installing (page 10)
3. DO burn seasoned wood fuel only or processed solid
fuel firelogs.
4. To avoid glass breakage, DO NOT slam the fireplacedoor.
5. DO NOT use gasoline, lantern-type fuel, kerosene,
charcoal lighter fluid, pellet stove lighter gel or similar
liquids to start or freshen up a fire in this fireplace.
Keep all such liquids well away from the fireplace
while it is in use.
6. DO NOT overfire the fireplace. If the chimney connector behind the top louver glows red, or if you
are unable to slow down the burning rate of thefire, you are probably overfiring the fireplace.
7. DO operate the fireplace with door fully open or
fully closed. If door is left partly open, gas andflame may be drawn out of the firplace opening
creating risk of both fire and smoke.
8. DO keep all combustible materials (furniture, shoesetc.) at least 4 feet away from the front of the fireplace.
9. DO not use a fireplace insert or other products not
specified for use with this fireplace.
10.DO not operate without or with a damaged gasket. To
do so will cause damage to the fireplace.
CREOSOTE
When wood is burned slowly, it produces tar and otherorganic vapours, which combine with expelled moisture
to form creosote. The creosote vapours condense in therelatively cool chimney flue of a slow burning fire. As aresult, creosote residue accumulates in the flue lining.
When ignited, this creosote makes an extremely hot fire.
The chimney must be inspected periodically during theheating season to see if a creosote buildup has occurred.
If a significant layer of creosote has accumulated (1/4" ormore), it should be removed to reduce the risk of chimney fire.
Warning: burn seasoned wood only!
Do not burn: - driftwood- treated wood- coal- garbage- plastic
Do not use construction scraps (e.g., 2x4 or plywood
scraps) as your only supply of fuel, as you may overheat and seriously damage the fireplace. Use no
more than 3 densified fuel logs (e.g. Presto Logs), at atime. Do not poke or stir the logs while they are burning.
Use only firelogs that have been evaluated for fireplace
use and refer to firelog warning and caution markingsprior use.

GENERAL SPECIFICATIONSCOMBUSTION CONTROL SYSTEM
Since the doors are sealed, all combustion air mustcome from outside the house through a draft control.
This control has a bimetal coil to allow more air when theunit is cold, and less air when the unit is hot, guarding
against overheating. It can be controlled either manually with the lever that is located above the lower right side
louvers, or automatically with an optional electric wall
thermostat.
For the first few days, it is best to operate the fireplacewith the manual control fully open (moved to the right as
far as possible). Just control the fire as you would any
normal fireplace using two or three logs at a time for asmaller fire, or more logs for more heat. Once you
become familiar with operating the fireplace with the control open, you can start experimenting with lower settings. Remember: when the fireplace is hot, the control
will not need as much movement to reduce the fire as
when it is cold. The bimetal coil will already have shutthe damper part way.
FIRESCREEN (option)
If you want to use the fireplace with the doors completely open, you have to run it with the firescreen (FDFSD) in
front of the opening. The firescreen will avoid sparks tofall on the floor. When using the firescreen do not leave
the fireplace without any supervision. This option isabsolutely needed if you want to use the fireplace thedoor open.

DELTA
THERMOSTAT (option)
If you want constant heat, day and night, you will be surprised of what the wall thermostat option can do for you.
Once you have your fire burning, just set the manual control on low (push the draft control lever all the way to theleft) and let the automatic thermostat take over. Yourroom temperature will keep as even as though you were
heating with oil, gas, or electricity - except you will findwood heat more comfortable (see Options: Wall
Thermostat part FDHC4).
NOTE: This thermostat controls the combustion air rate,
not the internal circulating blower.
INTERNAL CIRCULATING BLOWER (option)
If you have the optional internal blower installed, adjust
the speed of the blower to the output you require. The
blower speed control should have been installed at aconvenient place on the wall. When a fire is burning, thethermo disc installed inside the fireplace will turn on at
110° F, allowing the blower to operate; this will take about
20 minutes from the time you start the fire. When the
Delta cools to 90°F, the switch deactivates the blower.
The maximum heat output of the fireplace is greater withthe blower running (see Options: Circulating Blower part
FDHB5-N).
GRAVITY VENT SYSTEM (option)
If there are areas in your home that you would like toheat either in an upper level or an adjacent room, thegravity vent system can provide this heat with or without
the use of a blower. It is controlled by a gravity ventdamper. The handle is located above the top left louversof the fireplace. Simply turn the lever to adjust the air
flow through the gravity vent ducting. As the hot air rises,
it will be distributed through the insulated ducting to theoutlet (see Options: The Gravity Vent System part FDVD,
page 24).

Page 4
HINT: If some evening you would like to enjoy the ambience of the wood flame, but you are a little too warm, turnup the central heating thermostat and open a window inthe room the ducting goes to. This will keep your roomin front of the fire from getting too warm.

OPERATION
THE FIRST FIRE
Before the first fire, be absolutely sure to wipe off all fingerprints and debris from the gold plating, if you havechosen this option. The plating undergoes a sealing
process during this first fire, and the acid from your finger
prints will permanently etch the gold plating. You will
experience a slow start-up during the first fire. The
refractory bricks still contain moisture and take a good
hot fire to get rid of the moisture. While there is moisturein the bricks, the bricks will be black with smoke deposits.
When the moisture is gone, the bricks will turn white.
You will experience an odour during the first few fires.
This odour results from the curing paint and the burn-offof oil from the heat exchanger. Ventilate room to expel
odours.
LIGHTING
Slide the draft control that is located above the lower
right side louvers all the way to the right. Light a fire in
the fireplace, starting with paper and kindling only. Thenadd 2-3" diameter wood. After the fire is established,close the doors to prevent overheating of the fireplaceface. The unit is designed to accept combustion air
through the outside air duct only. (See the Combustion
Control System, page 5) Never use any flammable liquids. Once a coal bed is established, add standard cord
wood. Leave the draft control open until the fire is welllit, then adjust it to the level you desire.
Warning: Do not use a grate or elevate the fire.

CENTRAL HEAT SYSTEM (option)

REFUELLING

You have the option to heat remote rooms in your homefrom the heat generated by your fireplace. If this option
is installed, there may be a thermostat installed in themain room you want to heat, away from the room that
contains the fireplace. Or a thermostat installed thatremoves heat from the fireplace when the main room you
are trying to heat reaches the desired temperature. This
thermostat controls the blower, which brings air to theother rooms in your home, keeping them at the temperature you desire. When the blower is running, it takes air
from the room the Delta is in, draws it around the fireplace and distributes it (see Options: Central Heating
System parts FDHC6/FDHB6).

Fuel wood can be of any species. However, ensure thatthe wood is well seasoned and kept under cover.

NOTE: The blower (part FDHB6) can push warm aireither up or down, and can also be zone controlled (seeOptions: Zone Heating and diagrams).

NOTE: The central heat and internal blowers, if installed,should be shut off during refuelling to prevent smokefrom spilling out of the fireplace.
The door should be opened slowly to keep smoke fromspilling into your room. If you do have smoke spillage,
check to see that all kitchen and bathroom fans havebeen shut off. They can cause a vacuum in the house,
which pulls smoke out of the fireplace.

removing the door, and loosening the small Allen screws
on the right side of the hinge. The hinge pins are manufactured off-centre to facilitate easy adjustment. With aflat screwdriver, the pins can be turned so that the doors
seal well and fit with each other. After adjustment, tighten the Allen screws, holding the hinge pins in place withthe screwdriver, and replace the door. If the left side door
fits correctly and the front door does not pass the paper
test, then the angle bracket needs to be adjusted.
Loosen the four screws that are attached to the centre
door and slightly adjust the Allen screws in the angle
bracket inward. Tighten the two screws closer to the gasket first then the other two screws. Once the left part ofthe door seals well the door closer may need to be readjusted. If there is no more adjustment in the door closer
the right side door must be loosened and adjusted slightly to the right. Adjust the left door until the doors seal. If
the door seal is damaged to the point where it does notseal tightly, the gasket may need to be replaced. The
gasket replacement kit (part FDGRK7) is available fromyour dealer.

MAINTENANCE
CLEANING
The high heat paint and gold plating can be cleaned witha soft moist cloth. Use a mild detergent and water. Do
not use abrasive cleaners!
ASHES
Clean the ashes before they become too deep, i.e.,
before you have a spillage problem when opening thedoors.
Ashes should be placed in a metal container with a tightfitting lid. The closed container of ashes should beplaced on a non-combustible floor or on the ground wellaway from all combustible materials. If the ashes aredisposed of by burial, or otherwise locally dispersed, theyshould be retained in the closed container until all cinders have thoroughly cooled.

The door seal is the most important factor in controlling the burn rate of your Delta fireplace.

DOORS
Lubricate the door latch and hinges with an all-purpose
grease at least once during the burn season. The door
has been fitted and adjusted correctly at our factory.
Under normal conditions only the door closer shouldneed adjustment. To adjust the door closer catch, loosen
the two screws that hold the door closer in place. Slide
the door closer in 1/32" increments to the right, tighten
screws and (as shown in figure 1a) test to ensure that thedoor closes tightly. To check if the door seal is tight, try toslide a piece of paper behind the door gasket from the
top and bottom of the door. If the door closes tight andyou can still pass a piece of paper past, the gasket may
need replacing or the doors need readjusting.

GLASS
In a controlled combustion firebox, temperatures are notalways high enough to keep the glass perfectly clean.
We have supplied you with special ceramic glass that willwithstand the heat from the fireplace without cracking.
A good hot fire usually cleans off most of the deposits
that have accumulated.
Remember: the drier the wood, the cleaner the glass.
A word of caution: although heat will not break the glass,be careful not to hit the glass with logs.
NOTE: Cleaner glass means a cleaner flue.

If the door has been replaced the following may needadjusting. First check that the right side door is in thecentre of its adjustment. Adjust the hinges so the door
closer closes the door. The hinges are adjustable byWarning: Never clean this glass with an abrasive
cleaner. Use only a cleaner recommended by yourdealer. Never clean the glass while it is hot.You risk
getting a serious burn.

PAINT

If your glass breaks, call your dealer for the exact
replacement glass and instructions on how to replace theglass and gasket.

You may touch up the face of the Delta with STOVEBRIGHT flat black high temperature paint. The correct
paint is available from your dealer. When you paint theface of the fireplace, remove or cover the gold items (i.e.,
doors and louvers), and cover the area surrounding thefireplace with newspaper. Follow the directions outlinedon the spray can. DO NOT attempt to paint while the fireplace is still warm. Keep the spray can away from any
source of heat or open flame. Ensure that there is adequate ventilation in the room from the time you start
painting until the paint is dry.

1. Remove the door from the fireplace by lifting it off thehinges. If the right side glass needs to be replaced
remove door by removing the adjustment/mounting
screws (See Figure 1).
2. Remove the clips holding the glass in place.
3. Clean out any bits of glass and dirt from the gasket.

REFRACTORY BRICKS INSTALLATION
4. Place the new glass into the opening and replace theclips, being careful not to overtighten the screws.
5. Check the glass by trying to move it back and forth. It
should feel snug, but move slightly without too much
effort. If the right glass was replaced, replace the door
and adjust it square with the centre door. See section
DOORS if the door needs adjustment.
GOLD PLATING
If you have gold doors or gold louvers, you will be happy
to know that they will not tarnish. However, they are notscratch resistant and require a totally abrasive freecleaning. Use only mild soap and warm water to clean
the gold when the surface is cool. The use of any household clea-ner, such as Windex, abrasive cleaners, or any
form of acid, may permanently etch or remove some of
the gold plating. Before every fire, be absolutely sure towipe off all fingerprints from the gold plating. Acid fromdebris or your fingerprints may permanently etch the gold
plating.

The refractories or refractory bricks for the Delta fireplace
are placed in the fireplace at the factory. If, for any reason, they should need to be replaced the following ordershould be observed.
The bottom refractory R4606 and R4605 should beplaced at the bottom of the firebox. The two rear refractories R4602 and R4601 should then be positioned taking care to place them as in the diagram. The two side
refractories R4604 and R4603 are then positioned once
again being careful to place them properly. If the refractories on the back and sides do not fit immediately into
position as in the diagram they should not be forced. The
refractories can only be fitted into place as they were
designed to do. The last three refractories should beplaced in front from left to right looking at the fireplace
R4608, R4609, and R4607.
These directions should be reversed in order to remove
the refractory bricks from the Delta.
11.4.DCHIMNEY CLEANING
Check the chimney for creosote buildup every month
until experience shows how often cleaning is necessary.
A buildup of 1/4 inch or more should be cleaned mechanically before more creosote accumulates. Use a plastic
bristle or wire brush that fits correctly into the chimney.
The baffle in the firebox can be removed to gain accessto the flue from below.
To remove the baffle, first remove the secondary air pipe.
This can be done by removing the cotter pin from the top
right side of the secondary air pipe and sliding the pipe
as far as it goes to the left. Then when the right side
drops out of its hole, slide it to the right until the otherside drops. To remove the baffle, push up and slide it off
the brackets. Replace both as you removed them and be
sure the holes on the secondary air pipe are facing
toward the front.

LOCATION

Due to the weight of the Delta we recommend you use afurniture dolly and place the Delta as shown in the diagram below. The Delta weighs 620 lbs. complete and 450
lbs. stripped. The Delta should be stripped before moving it if possible. Elevate the fireplace and dolly to a 45°
angle to move.

Your Delta fireplace may be installed in many different
ways (see Figure 5) without any special floor reinforcement.

NOTE: If using an Eskelera a 2 x 4 will have to be placed
between the two forks before using.

Warning: If this fireplace is not properly installed, ahouse fire may result. For your safety, follow the
installation directions and clearances.
1. Note the location of roof and floor joists. Choose alocation that does not require cutting them.

CEILING CLEARANCE
Ceiling clearance is the distance from the top of the fireplace to the ceiling.
Under no circumstances is the distance between the ceiling firestop and the top of the framing guide to be lessthan 38 inches.
OUTSIDE AIR DUCT
After the fireplace is correctly positioned, connect the
combustion air inlet duct to the outside. A 4 inch diameter can be use if the total run of the pipe is less than 25
feet. If the total run is longer than 25 feet, a 5 inch diameter flexible pipe must be used.
1. Use the side or back outside air outlet.

This fireplace is certified for use with 8" ICC model Excelchimney. The chimney system height from the top of thefireplace must be a minimum of 12 ft. and a maximum of
28 ft. The minimum system height of 12 ft. must be
increased by approximately 1 ft. for every 2000 ft. elevation above sea level. Every 30° or 45° elbow also
increases the minimum height by 1 ft. For example, if
you are living 6000 ft. above sea level, your chimneymust terminate at least 15 ft. from the top of the fireplace(12 ft. + 3 ft. for the 6000 ft.). See table #1 bellow for
more precise recommended flue heights.
CHIMNEY INSTALLATIONNOTE: The clearance between the chimney and combustible material must be 2" or more. DO NOT fill thisarea with insulation.

2. Find a convenient location forthe combustion air duct andintake air hood. The locationof the intake air hood may be
above or below floor level(see Figure 7). Under no circumstances should the combustion air inlet be placed in
attic spaces.
3. Make a 4 1/4" (5 1/4" if using

be enclosed in a chase structure. It is best to locate thechase away from any overhead obstructions and meet all
clearances from such objects. The chase should be constructed in such a way that it is an extension of the home.
It should be well insulated between the footings and thefloor of the home to prevent heat loss. If the climate inyour area is mild, insulate the chase at least to the first
firestop. If the climate in your area is very cold, insulate
the chase to the top to keep the flue warmer, to increase
the draft, and reduce creosote buildup.
If required by local codes, make certain that the walls
have been properly insulated, vapour sealed andsheathed with a fire rated gypsum board (see Figure 910).

DELTA OPTIONS
Just a few comments about your Delta options. The sizeand shape of your home and how you intend to use yourfireplace will determine the options you require.
For a basic, high-efficiency fireplace, you won’t need any
options or electricity.
Temperature control can be accomplished by adding thethermostat option (part FDHC4). The thermostat automatically controls the amount of combustion air to the fire,leaving your home at an even preset temperature. If you
plan to heat your home with the fireplace, the thermostat
option will increase comfort, end the fuss of continual
manual adjustment, and reduce wood consumption.
For more heat output and increased air circulation, you
can add the internal blower (part FDHB5-N). For larger
homes in colder climates, this is an important option if
you plan to use the fireplace as an important source ofheat.
NOTE: It will be difficult to install the internal blower ifwiring is not run during framing. If there is any chancethat this option will be installed in the future, powershould be run to the fireplace and wire must be run to aswitch box at a convenient place on the wall for mounting the blower control.

1. Remove both right side louvers. They are held inplace by springs underneath, so push down from the
top and pull forward.
2. The damper motor and transformer are mounted on abracket in the bottom right hand corner of the fireplace (see Figure 19).
3. BEFORE fastening the controls with the 2 screws
provided, thread the supplied chain through the spare
keyhole in the draft control and attach a pendant to
the end, just like the chain that is beside it. Let the
chain down on the same side of the heat shield as theexisting chain, and attach it to the lever on thedamper motor with another pendant. Push the pendant snug into the hole in the lever. Then mount thecontrols to the bracket.
4. Adjust the chain on the draft control lever until it is justsnug but the damper is still closed. When the damper
motor is energized, the damper should open all theway. Lock the chain onto the keyhole with anotherpendant just like the chain beside it.
5. Wire the thermostat as shown in (Figure 19), using
20/2 wire, making sure the wall control is sufficiently
away from the direct radiation of the fireplace. Make
certain that it is at least 10 ft. away from the fireplace,

If you have room directly above or adjacent to the room with the fireplace which black
you would like to heat, you may consider white
the gravity vent option (part FDVD). The groundgra-vity vent distributes hot air to this (bare)room and requires no blower to assist its
operation. However, with the internal
blower (part FDHB5-N) installed, there will
be some increase in warm air movement
to the room serviced by the gravity vent.

If you desire even heat throughout yourhome strictly from your fireplace, or if you
want to move heat to a remote area of yourhome, it is recommended that you incorporate the central heat option (parts
FDHC6 and FDHB6). A thermostaticallycontrolled blower takes heat from the fireplace, and distributes the warm air
throughout your home - even several stories up or down.

but in the same room. An interior wall is recommended for thermostat installation.

5. Mount the provided speed control in a switch box at aconvenient location on the wall and connect it withconventional 90° C 18 gauge wire (see Figure 20).

CIRCULATING BLOWER (FDHB5-N)
GOLD LOUVERS (FDLD)NOTE: It is important that the wiring for the blower kit isinstalled during framing so that the wiring can be easily
hidden.
1. Remove the bottom middle louver. It is held in placeby springs underneath. Therefore, push down fromthe top and pull forward.
2. Hold the blower with the outlet facing up from theback. Fit the blower through the louver opening.
3. Slide the blower into the two blower mounts being
sure that it is pushed all the way down.
4. Mount the thermo disc as shown in (Figure 21). The
front face of the fireplace is bent into a flange justabove the lower opening. The thermo disc mounts
just above the centre louvers. Push the clips on to theflange as far as they will go.
NOTE: One thermo disc is all that is required to operate
either the internal blower, the central heat blower, or
both.

The standard black louvers above and below the doors
can be replaced with a gold plated set. You may orderthese from your dealer.
Dismantling and assembling louvers
For the following refer to (Figure 22):
1. The louvers are held in place by springs underneath.
Therefore, to remove, push down from the top andpull the top of the louvers forward.
2. Take the assembly apart by removing the top nuts
from the rods. Leave the bottom nuts and springassemblies on the ready rod.
3. Assemble the louvers the same way the black ones
came apart, reusing the original rods, spacers andsprings. There should be about 1/4" of the rod protruding above the top nut.

plating. The gold louvers have been coated with a silicone substance that will seal to the gold louvers during the first fire. If you do not wipe off the gold plating,the acid from your fingerprints or other substances will
permanently etch the gold plating.
NOTE: Although the gold plating will not tarnish, caremust be taken not to scratch the surface.
DELTA ROCK RETAINER KIT (FDKD)
FacingFacing material may only be non-combustible such as
metal, brick, rock, concrete board, or ceramic tile.
Gypsum board is NOT an acceptable facing material.

Warning: DO NOT restrict air flow through the inlet andoutlet louvers of the fireplace.
If you desire to fully face the fireplace with soldiering
brick, it is recommended that you purchase the rockretainer kit (part FDKD-1) to help keep the facing inplace. It is NOT recommended for brick or other selfsupporting materials. Follow these steps:
NOTE: Remove the fireplace doors and louvers, andstore them in a safe place until the masonry work is finished. Acid from the cleaning operation will permanently damage the gold plating. Ensure that the coverremains over the right door.

NOTE: The louvers have two sets of mounting holes.
Use the rear set when there is no

3. Mortar must be "thin set" or "thin bed" type, inherently polymer modified. Do not add water to the mixture(this applies to the grout as well). If the mortar is not
modified, you should add a synthetic latex additive.
Mix to a firm, moist consistency.
grill adaptor
4. Using a plasterer’s or mason’s trowel, apply a scratchcoat that covers the wire mesh. Let the mortar set
before adding another coat. This will take several
hours. Afterwards, apply a thinner coat and the facing. Do not spread plaster over more than a workablearea so that the mortar will not set before the facing isapplied.
5. If additional mortar is required, use a grout bag to fillin the joints. Take extra care to avoid smearing on thesurface of the facing.
Optional redesign of upper louver area
You may use other decorative materials to cover theupper louver area. However, you must follow the following criteria:
If any material is placed in front of the louvers (brick, tile,etc.) the louvers must first be permanently removed.
The final open area over the louver must be at least 50%of the area of the opening or 100 square inches. For
example see (Figure 25).
REMOTE VENTING
The gravity vent system can distribute air to an upper
level or a room next door without an extra blower. The

Figure 27: Gravity vent kit (FDVD)
central heat option allows heat to be sent up to 50 ft.
away. (Figure 26) illustrates various certified venting
options.
THE GRAVITY VENT SYSTEM (FDVD)
The FDVD Kit (see figure 27) includes:- a grille- a grille adapter- a B-vent starter section- a shut-off damper
IMPORTANT: No substitution of any of these parts isallowed. These genuine RSF Woodburning
Fireplaces parts have the correct clearances. These
clearances must be maintained for your safety exept
that B-vent components can be replace by ICC double wall black pipe ULTRABlack UBF (use only UBF
black pipe).
The FDVD system incorporates standard 8" B-vent components for installation. Single wall pipe is not allowed
due to the high temperature of the air in a gravity ventsystem. Any listed brand of 8" B-vent pipe may be used
and is not a part of the FDVD . The maximum pipe lengthis 15 ft. from the top of the fireplace to the outlet.
Remember: double wall black pipe from ICC may be
used instead of B-vent pipe.
(Figure 28) indicates the minimum clearancesand framing dimensions. Passing through a
combustible wall or ceiling requires a minimum
clearance of 2" from combustibles.
Warning: Every measurement and clearance
on the illustrations must be followed toassure safety of the installation.

Installation
CAUTION: Do not replace the grille from (Figure 28)
with shutters. Do not allow heat to be trapped in thegravity vent system.
1. Plan the gravity vent run first. Be aware that the maximum actual pipe length between the top of the fireplace and the outlet is 15 feet. There is no maximum
number of elbows in a run, but the run must never go
in a downward direction as this can trap heat in thegravity vent system.
2. The grille adapter is designed to be installed underneath the gypsum board in the wall. In the desired
location, frame a 13" x 13" hole to accept the gravity
vent grille adapter. Fit the gravity vent grille adapter
into the framed hole and fasten it into place with nails
or screws. If you are installing the outlet in an alreadyfinished area, you must remove the gypsum board
and frame a 13" x 13" hole in the existing framing, inorder to meet the required clearances.
3. Remove the outer cover to the left side of the flue outlet on the Delta.
4. Cut the insulation to the size of the opening and slide
the cover plate underneath to the side (it is taped inplace).

5. Install the B-vent starter section. By putting your hand
up inside and underneath, bend up at least two of thefour tabs at the base of the starter section to hold it
in place.
6. Install the “shut-off” damper in the B-vent starter section through the left side louvers. The shut-off damper
enables the manual control of hot air flowing throughthe gravity vent pipe. With the top left louver
removed, and the angular portion of the rod in hand,
insert the damper rod into the rear hole in the starter
section. The rod should slide in and down the keyhole, making sure that the #2 washer and spring on
the control arm are both on the outside of the starter
section and #1 washer is inside the starter section. A
definite tension should exist between the shut off
damper rod and the starter section. Replace the louvers. The damper rod should protrude above the topof the louvers.
7. Install the B-vent pipe between the B-vent starter andthe grille adapter. Fasten each joint with 3 screws (ifthe B-vent pipe manufacturer allows this in theirinstruction manual). Insert the B-vent pipe in the grilleadapter and fasten it with three screws. The B-ventpipe needs only to be inserted into the adapter
enough to be able to screw it in place. This allows
you about 3 ½" of play.

Note: grill is to be oriented"down" into the room as shown.

THE CENTRAL HEAT SYSTEM
To install the central host option you will need:blower speed
control
mounting
bracketFigure 29 : Central heat blower kit (FDHB6)

When ducting from the top of the fireplace the 8" backdraft damper prevents hot air from travelling into the ‘C’ vent (single wall) ducting unless the Central Heat Blower(FDHB6) is operating. When the thermostat calls for heat, the blower turns
on and opens the one-way valve. At thesame time, the room air is drawn
through the upper and lower louvers,noise reduction
which mixes and reduces the overallcollars (2)temperature of the forced air that travels
through the ducting.
NOTE: The central heat ducting may be
run at a 0" clearance to combustibles.

Warning: If you are ducting out of the top of
the fireplace and the backdraft damper is notinstalled, the central heat ducting will

1. Remove the cover to the left on the top of the
Delta.
2. Cut the insulation to the size of the opening
and slide the cover plate underneath to theside (it is taped in place).
3. Install the back draft damper crimped side
up, making sure it is pushed all the way
down. Bend out the 4 top tabs once installbend out the tabs on the lower edge of thedamper in at least 2 places inside the fireplace with a pair of pliers, so the back draft
damper cannot be pulled out again.
4. Before proceeding with the installation of theblower,make sure that the electrical service to theblower is in the “OFF” position. All wiring
should be in accordance with local ordinances and the National Electric Code.
NOTE: The blower can basically be installed
anywhere in the home. However, some thought
should go into the planning, to ensure that thePage 20

DELTA
blower noise does not affect rooms you would like kept
quiet. If the central heating system duct work is passing
through an area in your home that you do not wish to beheated, then the ducting should be insulated. Length of runs
should be as short as possible to conserve space and minimize cost. There is a loss of about 15% performance at 50
feet. Also: for your safety the blower automatically shuts
off if the air temperature reaches 180° F inside the ducting.
5. Locate the blower in a convenient location. The blower
may be installed vertically or horizontally. The horizontal
installation can utilize either the supplied mounting bracket or, if you want to install the blower farther away fromthe ceiling, you can use plumber’s strapping. A verticalinstallation must include the mounting bracket.
NOTE: If you have an existing hot air system, you may safely tie-in to this hot air system. However, no hot air duct is tobe connected to the return air of another central heating system.
6. Connect the INLET of the blower to the ducting comingfrom the fireplace, using 8" diameter metal ducting (rigid
or flex). Any other size will not work properly. Use only
metal ducting between the fireplace and the blower. You
may use plastic ducting after the blower, provided thetemperature rating of the ducting is at least 250°F. Do
not use plastic ducting in a chase.
7. To install the blower (for the FDHB6 blower only), attach
the noise reduction collars to either side of the blower

using 1/2" self-tapping screws.
8. Duct-work can then be run to the desired rooms. Up tosix - 5" or five - 6" diameter runs can be installed from thissystem.
NOTE: Runs must be balanced as air travels along the pathof least resistance. Balance the air flow by diameter andlength of runs. Longer runs should have larger diameters.
Houses vary in size and layout, so duct systems must be
specifically designed for each home. The diagrams on
this sheet are examples only. The cross sectional area of the
distribution system must total at least 50 square inches. If
you have more than 50 square inches, some of the system
may be shut off, but there must always be 50 square inchesof ducting open at all times. For example, if 5" pipe is used
for distribution, the cross section of each is 20 square inches. The minimum allowable ducting would be three runsof 5" pipe.
(Figure 33 and 34) illustrate two examples of tying in to existing duct work. Directing air in the right direction will reducereverse flow when the existing furnace blower is off. Somereverse flow will not cause any problems.
CAUTION: Tie-ins into existing duct work must be down
stream from the existing furnace.
NOTE: When the central heating blower is in operation, it
removes air from the room containing the fireplace. If thisroom can be closed off from the rest of the house (e.g. witha door), a grille with at least a 100 square inch open area

Otherwise periodic smoking from the fireplace will result.
9. Wire the blower to a 115 volt, 15 amp breaker through theterminal block provided. The variable speed switch provided should be installed in a convenient location near
the fireplace so the blower can be shut off during refuelling. The blower transformer relay should be placed inan accessible location near the blower. It should be
mounted in a 4x4 electrician’s box. You have two optionsof how you can connect the central heat blower to theblower control assembly. Follow the wiring diagram on(Figure 42).
a) If you would like the blower to turn on when the thermostat calls for heat, first locate the thermostat in theprincipal room heated by the duct system (this is the mostpopular use of the central heat blower). Do not install itin the room where the fireplace is installed. We recommend an electrician wire the following. There are yellow,
black and red wires coming out of the relay as shown in
the wiring diagram. Connect the wire from #4 of the terminal block to the yellow relay wire and the black transformer wire with a wire marrette. Connect the black relay
wire to the variable speed switch and leave the red wire
unconnected with a wire marrette attached for protection.
Connect the neutral (the white wire) to the wire from #6
terminal (see Figure 32).
b) If the fireplace is in a small room and/or you would
like the central heat blower to remove air from this room
when it becomes too hot, locate the thermostat in theroom with the fireplace (this is a less common use of thecentral heat blower). We recommend an electrician wireb) To assure proper contact, check the motor leadwiring, incoming supply wiring, and capacitor connections.
c) If possible, use a meter to test for continuity
between the fan leads. Please note that the capacitor willshow no reading if it is tested with a meter.
2. If the blower still fails to operate, consult your local RSF
Woodburning Fireplaces authorized dealer for repair or
replacement instructions.
ZONE HEATING (FDHCZ-1 AND FDHCZ-2)
For more regional heat control, the Delta is ideally suited forzone heating. (Figure 38) shows an example of a three zone
system. The thermostat simultaneously opens the desired
valve and starts the blower when heat is required. The zone
control system consists of:
1 - FDHCZ-1(figure 32)- 1 control box- 1 blower transformer relay- 1 thermo disc

NOTE: The FDHCZ-1 replaces the FDHC6 if you areinstalling the zone system.
1 to 3 - FDHCZ-2(figure 33)- 1 zone valve (normally closed)- 1 thermostat

The system is wired similarly to the central heat system withthe addition of the control box and the zone heat valve (seeFigure 39). The whole system runs on 24V AC. Make surethat the thermostats are matched with the correct zone valve.
NOTE: THE Delta MUST BE INSTALLED IN ACCORDANCE WITH ALL LOCAL CODES, IF ANY. IF NOT, FOLLOW THE CURRENT CSA C22.1 IN CANADA OR NFPA70
IN USA. INSTALL AND USE AS PER THE MANUFACTURER'S INSTALLATION AND OPERATING INSTRUCTIONS.
