Floor protector’s come with various types of
specifications. To convert a floor protector’s specification
to an R-value, do one of the following: If the R-value is given, use that value—noconversion is needed.
 If a K-factor is given with a required thickness(T) in inches, use this formula: R-value = 1/K x
T If a C-factor is given, use the formula: R-value =1/C
To determine the R-value of the proposed alternate floor
protector:
 Use either the K-factor or the C-factor formula
explained above to convert specifications not
expressed as R-values.
 For multiple layers of floor protectors, simply
add the R-values of each layer to determine theoverall R-value of the layers.
If the overall R-value of your setup is greater than the
R-value of the specified floor protector, then your setup is
acceptable.

fireplace must be restored to its original condition for safe
use without the insert.

It is very important to follow minimum clearances forchimney connectors to combustibles such as walls andceilings when installing the stove near noncombustible surfaces. Typical chimney connector
clearances are outlined below. The single wall
clearances are generic; the Double wall clearances arefor Simpson Dura Vent DVL, CHECK THE
SPECIFICATIONS
FROMTHEMANUFACTURER OF YOUR CONNECTOR.

INSTALLING A VENTING SYSTEM
DO NOT CONNECT THIS UNIT TO ANY AIR
DISTRIBUTION DUCT OR SYSTEM
Secure all joints, including attaching the stovepipe to theFireplace Insert's flue collar, with three sheet metalscrews. Install #10 x 1/2" (3 mm x 13 mm) sheet metalscrews into the holes pre-drilled in the flue collar.
Leaving off the screws can cause joints to separate fromthe vibration that results from a creosote chimney fire.
Long runs of stovepipe to increase heat dispersal are notrecommended. Using longer lengths of stovepipe or moreconnecting elbows than necessary increase the chances ofdraft resistance and the accumulation of creosote buildup.
Remember, the NFPA has recommended, minimum
clearances for chimney connectors to combustibles suchas walls and ceilings. Once the Fireplace Insert isinstalled at safe distances from these combustible
surfaces, it is important to maintain these connector
clearances for the remainder of the installation.

Remember, you must adhere to all previously describedfloor protection requirements when installing into a zeroclearance fireplace.

CONNECTING YOUR WOOD FIREPLACE INSERTYou can install your Morgan to a prefabricated metalchimney or a masonry chimney. See figure 7 to aid inconnections.

▌ WARNING:
DO NOT CONNECT THE FIREPLACE INSERTTO A CHIMNEY FLUE SERVING ANOTHERAPPLIANCE.

CONNECTING TO A PREFABRICATED METALCHIMNEY (A FULL FLUE LINER IS REQUIRED IN CANADA)

Make sure the size of the chimney’s flue is appropriate for
the Morgan. The Morgan requires a 6" (152 mm) inside
diameter flue for new installations. A 6” diameter flueprovides adequate draft and performance. You can use an
8" (203 mm) diameter existing flue with a reducer. An
oversized flue contributes to creosote accumulation. (Inthis case, bigger is NOT better.)

IT IS STRONGLY RECOMMENDED THAT THISFIREPACE INSERT IS INSTALLED WITH A
CONTINUOUS CHIMNEY LINER WITH A
MINIMUM DIAMETER OF 6” EXTENDING FROM
THE FIREPLACE INSERT TO THE TOP OF THE
CHIMNEY.
THE
CHIMNEYLINER
MUST
CONFORM TO THE CLASS 3 REQUIREMENTS OFCHIMNEY LINER STANDARDS CAN/ULC-S635 OR
CAN/ULC- S640

When purchasing a prefabricated chimney to install withyour Fireplace Insert, be sure to also purchase from thesame manufacturer the wall pass-through (or ceilingsupport package), "T" section package, fire-stops (whenYou can install the Morgan in a masonry or zeroclearance fireplace.

needed), insulation shield, roof flashing, chimney cap,
and any other needed accessories.
Follow the
manufacturer’s instructions when installing the chimney
and accessories. In addition, be sure to maintain all
manufacturers’ recommendations for the proper
clearances to the chimney.

Whenever possible, choose an interior chimney. Aninterior chimney heats up more quickly and retains its
heat; thus promotes a better draft and discourages theformation of creosote. An exterior chimney does notbenefit from the warmth of being surrounded by thebuilding, so it typically operates at lower fluetemperatures than an interior chimney. An exteriorchimney’s draft is not as strong and may experience
increased creosote accumulation.

There are two ways to install a prefabricated metalchimney: An interior installation where the chimney passes
inside the residence through the ceiling and roof.

REMOVE DAMPER OR WIRE IT OPEN

An exterior installation where the chimney passes
through the wall behind the Fireplace Insert then up
the outside of the residence.

Use the following checklist to ensure that your masonrychimney meets these minimum requirements:
Chimney wall construction:
 Brick or modular block at least 4" (102 mm) thick.
 A rubble or stone wall.
Flue liner:
 Minimum thickness of 5/8" (16 mm).
 Installed with refractory mortar.
 At least 1" (25 mm) air space.
 An equivalent flue liner must be a listed chimney
liner system meeting type HT requirements or otherapproved material. Interior chimney requirements: At least 2" (51 mm) clearance to combustible
structure Fire stops must be installed at the spaces where thechimney passes through floors and/or ceiling.
 Insulation must be 2" (51 mm) from the chimney.
Exterior chimney requirements: At least 1" (25 mm) clearance to combustible
structure.
Chimney height requirements: (See Illustration)
 At least 3 feet (0.9 m) higher than the highest part of
the roof opening through which it passes.
 At least 2 feet (0.6 m) higher than any part of the roof
within 10 feet (3 m) measured horizontally from the
top of the chimney. This Fireplace Insert requires aminimum chimney height of 13 feet (4 m). The
maximum allowable chimney height is 30 feet (9m).

Surround Caps

Figure 8 Surround Cap Kit # 94-5970510 (matte) or
94-5970559 (blue/black)
Most zero clearance installations will raise the Morgan
approximately 6” off the hearth or floor. In order to finish
the surrounds, Hearthstone offers a surround cap kit. See
the illustration in figure 8 to see the placement of thesurround caps .

CONNECTION TO A MASONRY CHIMNEY
Consider two primary elements when connecting yourFireplace Insert to a masonry chimney: the chimney itself
and the thimble where the stovepipe connects to thechimney. Use only Code approved masonry chimneys
with a flue liner.
Before connecting to a masonry chimney, hire a
professional to examine the chimney for cracks, loose
mortar, and other signs of deterioration and blockage. If
the chimney needs repair, complete them before installingand using your Fireplace Insert. Do not install yourFireplace Insert until the chimney is safe for use.
Make sure the chimney’s cleanout is complete andworking properly. To avoid a loss of draft, the cleanout
must close off completely. If allowed to cool, yourFireplace Insert will perform poorly and creosote willbuild up in the chimney.
Make sure the size of the chimney’s flue is appropriate forthis Fireplace Insert and that it is not too large. Use amasonry chimney with an 8" x 8" (203 mm x 203 mm)

Hearthstone Quality Home Heating Products, Inc. ®

The surround must be sealed to the fireplace front or thedamper area around the chimney liner must be sealed toprevent room air from entering the chimney cavity of thefireplace.
WARNING Do not remove bricks or mortar from theexisting fireplace (Exception) Masonry or steel(including the damper plate) may be removed from thesmoke shelf and adjacent damper frame if necessary toaccommodate a chimney liner, provided their removal
will not weaken the structure of the fireplace andchimney, and will not reduce protection for clearance to
combustible materials to less then required by the

the firebox. Generally, the more air allowed into thefirebox, the faster and hotter the rate of burn; conversely,
less air creates a slower burn. To fully open the primary
air intake, push the handle as far as it will go to the righttoward the firebox; push the handle as far as it will go to
the left, away from the firebox to close the primary aircontrol.

FRONT DOOR: The front door allows you to load wood
into your Fireplace Insert; a fixed handle allows you tooperate the front door and allows you to latch the front
door closed. The front door can be reversed to open form
either side. To open the door, lift the handle to the 2o’clock (or 10 o’clock for RH mounted door) positionand pull the door. To latch the doors, push the door
closed tightly then lower the handle to the 4 o’clock (8o’clock for RH mounted door) position. Pull on the door
handle to make sure it is properly latched.
Reversing the door (Refer to Figure 9)
To switch the door to open from the right, simply remove
the ash lip assembly, and front facade. Remove the two
Phillips head screws holding the door hinges on (A+B in
Figure 9) (use caution, once the last screw is removed
the door will be loose in your hands) Be careful not tolose the two hinge rivets. Using a Phillips headscrewdriver remove the door catch (C in Figure 9) (Theremay be spacer washer behind the catch to provide anadequate seal. Remove the two screws where the hinges
will go on the left side. Rotate the door 180 degrees, andput the hinges in place. Reattach the door catch on the
opposite side of the front, using the same screws andspacer washers if necessary.

The quality of your firewood affects heat output, durationof burn and performance of your Fireplace Insert.
Softwoods generally burn hotter and faster, while
hardwoods burn longer and produce more coals. Density
and moisture content are two critical factors to consider
when purchasing wood for your Fireplace Insert.

soapstone must be driven out slowly to minimize the“shock” to the stone of its first exposure to high firebox
temperatures. In addition, the asbestos-free furnace
cement must be cured slowly to insure adequate sealing
and bonding.
When you light your first fires, the wood Fireplace Insert
will emit some smoke and fumes. This is normal “offgassing” of the paints and oils used when manufacturing
the wood Fireplace Insert. If you find it necessary, open a
few windows to vent your room. The smoke and fumes
will usually subside after 10 to 20 minutes of operation.
The odor and smoke will end once the Fireplace Insert is“cured”.

The following is a list of wood species and their relative
BTU (British Thermal Unit) content. The higher the BTU
the longer the burn. Firewood with higher BTUs is
generally considered ideal for a wood stove.
HIGH: Apple, Black Birch, Hickory, Locust, White Oak,Black Beech, Mesquite
MEDIUM HIGH: White Ash, Beech, Yellow Birch,
Sugar Maple, Red Oak

The first fires may produce other odors from impurities
that exist in the area immediately surrounding theFireplace Insert. Some of these impurities can becleaning solvents, paint solvents, cigarettes, smoke, pethair, dust, adhesives, a new carpet, and new textiles.
These odors will dissipate over time. You can alleviatethese odors by opening a few windows or otherwise
creating additional ventilation around your Fireplace
Insert. If any odor persists, contact your dealer or an
authorized service technician.

MEDIUM LOW: Black Ash, White Birch, Grey Birch,
Elm, Norway Pine, Pitch Pine, Black Cherry, Soft Maple,
Tamarack
LOW: White Pine, White Cedar, Balsam Fir, Spruce,
Aspen, Basswood, Butternut, Hemlock
Moisture content also plays a key role in the performanceof your stove. Wood freshly cut from a living tree (greenwood) contains a great deal of moisture. As you might
expect, green wood has difficulty burning and should beseasoned before using it in your wood stove. To properly
season green wood, it should be split, stacked and allowed
to air dry for a period of one year.

If you adhere to the following break-in procedure, as well
as all other operating procedures in this manual, the castiron and soapstone components of your Fireplace Insert
will give you many years of trouble-free use. With use,the color of the soapstone may change and small fractures
may appear on the surface of the stone. These changes
will only add character and distinction to your Fireplace
Insert.

Stack the firewood on skids or blocks to keep it off theground, cover only the top of the stack. Plastic or tarps
that cover the sides of the woodpile trap moisture andprevent the wood from drying. As for stacking, an old
Vermonter said, "The spaces between the logs should belarge enough for a mouse to get through, but not for thecat that's chasing it."

Avoid the following conditions that can cause thesoapstone or cast iron pieces to break:Firewood should not be stored within the Fireplace
Insert's specified clearances to combustible materials.



BUILDING A FIRE
Once you understand the controls of your wood Fireplace
Insert and have chosen the appropriate firewood, you areready to start a fire.

Do not throw wood into the Fireplace Insert.
Do not use the door as leverage to force wood into
the Fireplace Insert.
Do not load wood that is encrusted with ice into aburning stove as the thermal shock can cause
damage.
Do not use a manufactured grate. Burn the fire
directly on the soapstone that lines the bottom of thefirebox.

The bottom layer of soapstone in the firebox is intended
to prevent thermal stress and should remain in place in thefire box at all times.

BREAKING IN YOUR WOOD FIREPLACE INSERTBUILDING A BREAK IN FIRE

It is imperative that your Fireplace Insert be "broken in"
slowly. Cast iron must be "seasoned"; over-firing a newFireplace Insert may cause castings to crack or may
damage other Fireplace Insert parts. Moisture in theHearthstone Quality Home Heating Products, Inc. ®

BUILDING A FIRE FOR EVERYDAY USE
1) Open the front door and place five or six double
sheets of tightly twisted newspaper in the centerof the firebox. Arrange kindling in a crisscrosspattern over the newspaper. Kindling should beapproximately ten pieces, 1/2" (13 mm) indiameter and 10" to 18" (254 to 457 mm) long.

2) Fully open the primary air control bypushing the control handle fully to the right,
away from the firebox.

2) Fully open the primary air control by pushing itcompletely to the right, away from the firebox.

3) Light the paper under the kindling. Leave
the front door slightly ajar momentarily until
the kindling has started to burn and draft
begins to pull.

3) Light the paper under the kindling. Leave thefront door slightly ajar momentarily until thekindling has started to burn and draft begins topull.

4) Close the door and allow the fire to burn.
Keep the front door closed while theFireplace Insert is in use.

4) Close the door and allow the fire to burn.

5) KEEP A WATCHFUL EYE ON YOUR
FIREPLACE INSERT to maintain a steady,low-heat fire. Your first fire should makethe Fireplace Insert warm but not hot to thetouch. At most, a few small chunks ofwood should be added to the fire to reachsafe break-in temperatures.

5) Once the kindling is burning, open the front door
and add logs, small at first, to build the fire up.
Make sure to keep the logs away from the glassin front in order for the air-wash system to work
properly. Otherwise, keep the door closed while
the stove is in use.

6) Once the Fireplace Insert is warm but not
hot to the touch, close the primary aircontrol by pushing it fully to the left toallow the fire to die out completely.

6) Once the fire is burning well, use the primary aircontrol to regulate the desired rate of burn.
Pushing the handle to the right opens the
PRIMARY AIR CONTROL for a high rate ofburn or pushing it to the left for a low rate ofburn.

7) Let the Fireplace Insert return to room
temperature.

Note: When opening the front door to reload or
re-arrange logs, it is advisable to open the door justa crack, pause for a moment then open the door
completely. This procedure will allow the firebox
to clear of smoke before the door is opened fully.
Also, reloading on a bed of hot, red coals reduces
smoking time and will bring fresh fuel up to a hightemperature rapidly.

Your first fire and first fire each season thereafter should
be built and maintained as outlined above. Your patience
will be rewarded by a properly seasoned Fireplace Insert.
NOTE: Because of the cool flue gas temperatures present
during the break-in procedure, creosote may build up
quickly. Your window may get dirty. A good hot fire willclean it. We recommend a visual inspection (and cleaning
if necessary) of your stovepipe and chimney once thebreak-in procedure is completed.

OVER-FIRE CAUTION
Over-firing means the Fireplace Insert is operating attemperatures above the recommended temperatures
outlined above in the BURN RATE section. Over-firing
should be carefully avoided since it will cause damage to
the Fireplace Insert. Symptoms of over-firing include
short burn times, a roaring sound in the Fireplace Insert orstovepipe, and discoloration of the stovepipe.

NORMAL OPERATION
If your Fireplace Insert is not used continuously or has notbeen used in quite some time, follow the break-in
procedure at least once to minimize the stress of a hot fireon a cold Fireplace Insert before proceeding with normal
operation. We recommend one break-in fire at the start ofeach heating season.

Hearthstone Quality Home Heating Products, Inc. ®

Over-firing can be caused by excessive draft,inappropriate fuel, and operator error. Correct an overfire situation as follows:
14

Morgan Model 8470

EXCESSIVE DRAFT: Contact your dealer tohave a draft reading taken. Any draft in excess of 0.1 wc
requires a damper in the stovepipe. Some installations
may require more than one damper.
INAPPROPRIATE FUEL: Do not burn coal,kiln dried lumber, wax logs or anything other than natural
cordwood.
OPERATOR ERROR: Make sure all the gaskets
are in good condition. Replace worn out or compressedgaskets. Do not burn the Fireplace Insert with the front
door in the open position.

The stovepipe connector and chimney should be inspected
at least monthly during the heating season to determine if
a creosote build-up has occurred. If a creosote residue
greater that 1/4" (6 mm) has accumulated, it should be
removed to reduce the risk of a chimney fire.
If your glass is remaining dirty, your operating
temperatures are low; therefore, there is a higher risk ofcreosote buildup.
The venting system must be inspected at the Fireplace
Insert connection and at the chimney top. Cooler surfaces
tend to build creosote deposits quicker, so it is importantto check the chimney at the top (where it is coolest) as
well as from the bottom near the Fireplace Insert.

Monitoring the temperature of the surfaces is the best way
to determine if the Fireplace Insert is over-firing. If you
suspect that your Fireplace Insert is over-firing, contact
your dealer immediately. Damage done by over-firing
is not covered by your warranty. Results of over-firing
can include: warped or burned out internal parts, cracked
stones, discolored or warped external parts, and damaged
enamel.

Accumulated creosote should be removed with a cleaning
brush specifically designed for the type of chimney in use.
A certified chimney sweep should be used to perform thisservice. Contact your dealer for the name of a certified
chimney sweep in your area (your dealer may be acertified sweep!).

NOTE: ANY SYMPTOMS OF OVER-FIRING
WILL VOID YOUR WARRANTY!!

It is also recommended that before each heating season
the entire system be professionally inspected, cleaned andrepaired, if necessary.

MAINTENANCE

Do not over-fire the Fireplace Insert. (refer to page 14).

CREOSOTEREMOVALFORMATION

AND

NEED

FOR

GASKETS
Gasket material should normally be replaced every two to
three seasons, depending on Fireplace Insert use. If thedoor seal is loose, a new gasket will assure a tight seal
and improved Fireplace Insert performance. Contact yourdealer for a gasket kit that includes instructions andgaskets for your Fireplace Insert.

When wood is burned slowly, it produces tar and otherorganic vapors, which combine with expelled moisture toform creosote. These creosote vapors condense in therelatively cool chimney flue of a slow-burning fire. As aresult, creosote residue accumulates on the flue lining.
When ignited, this creosote makes an extremely hot fire,
which may damage the chimney or even destroy thehouse. When burning wood, the chimney connector andchimney should be inspected at least once every twomonths during the heating season to determine if acreosote buildup has occurred.

The procedure for replacing gaskets on the glass isreviewed below under “Glass”.
To replace door gaskets, first remove the old gaskets witha utility or putty knife. Clean all gasket channels with awire brush. Apply gasket cement to the channels andpush the new gasket into place without stretching thegasket material. The door should be shut immediately to
fully press the gasket into place and assure a positive seal.

To prevent the buildup of creosote:
1. Burn the Fireplace Insert with the primary aircontrol fully open for 35 - 45 minutes daily to burn out
creosote deposits from within the Fireplace Insert and theventing system.

GLASS

2.
After reloading with wood, burn theFireplace Insert with the primary air control fully open for
20 to 30 minutes. This manner of operation ensures early
engagement of the secondary combustion system which,when engaged, minimizes creosote buildup in thechimney.
Hearthstone Quality Home Heating Products, Inc. ®

Do not operate the Fireplace Insert with a broken door
glass. Do not abuse the front door by striking or
slamming.
When necessary, the glass can be cleaned with low
alkaline content commercial stove glass cleaners, which
15

Morgan Model 8470

are available from your local dealer. Never attempt toclean the glass while the fire is burning or the glass is hot.
Most deposits can be cleaned by following the
instructions provided with the cleaner. To clean heavier
deposits, remove the top hinge and lift the door straightup and off the Fireplace Insert (take care to save hardware
for reuse). Lay the door face down on a workbench ortable. Apply the cleaner to the glass and allow it to set fora few minutes. By laying the door flat, it will allow thecleaner to penetrate rather than running off the surface ofthe glass. Wipe the cleaner off with a soft cloth.

CAST IRON

The door glass should be replaced immediately if broken.
Contact your local dealer for replacement glass, which isaccompanied with instructions and everything needed forthe repair. If you replace the glass yourself, wear work
gloves and safety glasses.

Exterior cast iron parts are either painted with black, hightemperature stove paint or porcelainized with an enamel
finish in various colors.
Use black, high-temperature stove paint (satin black by
Stovebright) to touch up and maintain the original
appearance of painted cast iron. Use a damp sponge towipe clean. Dry the cast iron thoroughly to prevent
rusting.

The procedure for glass and glass gasket replacement is asfollows: Refer to Figure 9.
1.

6.

Remove the door by removing the top hinge
screw and lifting the door straight up off thebottom hinge.
Place the door face down on a flat, smoothsurface.
Apply penetrating oil to the screws.. Remove thescrews to separate the glass from the door.
Carefully lift the damaged glass from the door
and discard.
Replace the screws.
Install the door.

Enamel castings can be cleaned with a standard glasscleaner. With time and use, a very fine, subtle network ofcrazed lines may appear seemingly beneath the surface ofthe enamel. Crazing is a natural predictable process anddoes not represent a flaw.

TROUBLESHOOTINGYour Heating Needs
Virtually all woodstove operators experience basic
common problems at one time or another. Most are
correctable and generally require only a minor adjustmentof the stove, installation, or operating technique. In cases
where weather conditions dramatically affect stove
performance, the problems are typically temporary andsolve themselves once the weather changes.

WARNING Do not use substitute materials whenreplacing the glass or any door components. Only
authorized Hearthstone components should be used.
Glass specifications 18-1/2” x 12” x5mm neoceram

If you question whether your Fireplace Insert is producing
adequate heat, the best way to troubleshoot the problem is
to monitor the temperature of the stack. A 400 degree F
Hearthstone Quality Home Heating Products, Inc. ®

16Morgan Model 8470

(200 degree C) stovepipe confirms the Fireplace Insert is
supplying sufficient heat. Keep in mind that your houseitself will regulate room/house temperatures. How well
the walls, floors and ceilings are insulated, the number
and size of glass windows, the tightness of outside doors,
and the construction or style of your house (vaulted
ceilings or other open spaces which collect large
percentages of heat, ceiling fans, etc.) all are determining
factors of room temperature.

stovepipe joints, a poor stovepipe-to-thimble connection,
or a leaky chimney may cause inadequate draft.
SEASONAL FACTORS: Early fall and late spring are
generally difficult seasons in which to establish proper
drafts. The colder the outside air is (relative to room
temperatures) the stronger the draft.

Operating the Fireplace Insert
There are days when a draft is not easily established. As
outlined above, seasonal factors or a cold chimney may be
the cause. Try starting the fire by using small kindlingand fuel to obtain a quick, hot fire. Tend the fire
frequently with small fuel until the chimney is hot and thedraft is well established.

Your Fireplace Insert's performance is also dependant on
its installation. One common cause of poor performanceis an oversized chimney flue. Oversized chimney flues
result in decreased pressure, which prevents the smokefrom rising out the chimney. Oversized flues are also
more difficult to heat effectively, especially when burninga high efficiency Fireplace Insert. Cool flue temperatures
inhibit the establishment of a strong draft (and encourage
the accumulation of creosote). The lack of a strong draft
will cause the fire to die down and may even force thesmoke to pour into the room. If your chimney is theproper size and a strong draft is not easily established,
there is the possibility of the chimney being too cold.
Again, hot chimneys promote a stronger draft.

DISPOSAL OF ASHES
Ashes should be placed in a metal container with atight fitting lid. The closed container of ashes shouldbe placed on a non-combustible floor or on the
ground, well away from all combustible materials,
pending final disposal. If ashes are disposed of byburial in soil or otherwise locally dispersed, theyshould be retained in the closed container until allcindershavethoroughlycooled.

Other draft guidelines are as follows:
AN "AIRTIGHT" HOUSE: If your home is superinsulated or especially well sealed, the (infiltration) air
supply to the interior of the house may be inadequate.
This phenomenon of air starvation within the building canbe exacerbated if exhaust fans, such as clothes dryers,bathroom fans or cookstove exhaust fans, are in operation
within the home.
TALL TREES OR BUILDINGS: These obstructions,when located in proximity to the top of the chimney cancause chronic or occasional downdrafts. When selecting
a site for a new chimney, take care to consider theplacement of other objects near the proposed chimney
location.
WIND VELOCITY:
Generally, the stronger andsteadier a wind, the stronger (better) the draft. However,"gusty" wind conditions may cause erratic downdrafts.
BAROMETRIC PRESSURE: Chimney drafts are
typically sluggish on balmy, wet or muggy days. This is aweather-related phenomenon, which generally is selfcorrecting as the weather changes.
BRISKNESS OF FIRE: The hotter the fire in yourFireplace Insert, the hotter your chimney and, therefore,
the stronger the draft.
