Radiance® Direct Vent Gas Heater
Vent Termination Clearances
When planning the installation, consider the locationof the vent terminal and clearances. Some of the mostcommon clearances to keep in mind are shown in Figure
11.
Important: All vent clearances must be maintained.
Check your vent termination clearances against
Figures 11 through 13.
The vent should be placed so that people cannot beburned by accidentally touching the vent surfaces when
the stove is operating.
The vent termination should be located where it cannot
be damaged by such things as automobile doors, lawn
mowers or snowblowers and it should be located awayfrom areas where it could become blocked by snow,
etc.
Some considerations are:• 	 Obstructions or impediments to venting.
• 	 Nearby combustible materials that could come into
contact with combustion exhaust gases.

• 	 Other nearby openings {within 12” (305 mm)}through which exhaust gas could reenter the building.
• 	 All vegetation within 3’ (76 mm) that may interferewith the draft.
Other factors that influence where the installation will
be sited include the location of outside walls, where
additional heat may be desired in the home, where thefamily members gather most regularly, and perhaps
most importantly, the distance limitations of the venting
system.

Your stove is approved to be vented either through theside wall, or vertical through the roof.
• MHSC does not require any opening for inspection of vent pipe.
• Only MHSC, Simpson DuraVent and Selkirk
Corporation venting components specifically approved and labelled for this stove may be used.
• Minimum clearances between vent pipes andcombustible materials is one (1”) inch (25 mm),except where stated otherwise.
• Venting terminals shall not be recessed into a wall orsiding.
• Horizontal venting must be installed on a level plane
without an inclining or declining slope.
There must not be any obstruction such as bushes,
garden sheds, fences, decks or utility buildings within
24” from the front of the termination hood.
Do not locate termination hood where excessive snowor ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental blockage of venting system. When using snow
blowers, make sure snow is not directed towards venttermination area.

Location of Vent Termination
It is imperative the vent termination be located observing the minimum clearances as shown on this page.

IMPORTANT• 	 The horizontal termination must not be recessed
into the exterior wall or siding.
• 	 Horizontal vent runs must be level toward thevent termination.
• 	 Clearances around the vent termination must be
maintained.
• For installations using Simpson DuraVent pipe,
parallel installations with minimum wall clearance
have restricted access for connecting the Horizontal Vent Cap straps to the vent pipe. See themaker’s instructions for recommended installation procedures.

Use of Sealant
It is not required to apply or use sealant on the inner
liner of DIRECT-TEMP. For outer wall joint sealing
considerations, follow appliance manufacturer recommendations.
Joint Connection:
The pipe and elbows are assembled by inserting theoutlet (male) end of a length of pipe or elbow into the inlet (female) end of an adjacent length of pipe or elbow.
Make sure the outlet end is fully seated within the inlet
end of the adjoining section and the gasket, located on
the inner liner of the inlet section is fully enclosed by the
inner liner of the outlet of the adjoining section. Pushin the Lock Tab such that it becomes seated within the
inward groove of the adjoining section. This locks thejoint in place. (Fig. 34)
Supporting DIRECT-TEMP: Vertical Support
Vertical installations can be supported by two methods:

3. Push the appliance near the desired location. Determine the centerpoint of the penetration by locating thecenterline of the outlet of the pipe with respect to the wall.
4. Frame an opening to the dimension specified in the
Framing Dimension Table 1. Ensure the centerline ofthe pipe lines up with the center of the prepared opening unless otherwise specified by the appliance manufacturer.
NOTE: As a general rule, the wall thimble is optional in
the U.S. However, there may be some manufacturersthat require it. Contact the appliance manufacturer for
information if uncertain. When installed in Canada, awall thimble is required on all installations in which
the vent passes through a combustible wall.
5. If required, install the outside half of the wall thimble(WT) through the opening and screw or nail in place. (Fig.
41) Seal around the perimeter of the thimble face plate on
the exterior wall using an RTV silicone sealant to provide
protection from possible rain infiltration. (Fig. 41)
NOTE: The wall thimble accommodates wall thicknesses of 4Z\x” (114 mm) to 7Z\x” (191 mm). If a larger range
is needed due to a thicker wall, it is permissible to field
fabricate a metal sleeve extension and attach it to theshields.
6. Install the horizontal termination to the exterior wallusing four (4) all purpose screws through the holes
located at each corner of the termination. Make surethe arrow (embossed on the front of the termination)is pointing up. (Fig. 42) If the house has vinyl siding,

If the wall is brick or concrete, and contains no combustible material, a 7” (178 mm) round penetration
hole is adequate. The wall thimble is not required. The
perforated straps of the horizontal termination provide
a method of attachment. These can either be threaded
through the opening or wall thimble (if used) andscrewed to the pipe or removed with a pair of tin snips
if not used. Use proper masonry fasteners to attach thehorizontal termination to the wall.
7. If a wall thimble is used, push the pipe (which isconnected to the appliance) carefully through the wall
thimble until the DIRECT-TEMP pipe becomes fully
engaged with the horizontal termination. If no thimble isused, place the Trim Plate (TP) on the DIRECT-TEMP
pipe. Carefully push the DIRECT-TEMP pipe throughthe wall until fully engaged with the horizontal termination. Secure the trim plate to the wall.
NOTE: If a vertical rise is necessary on the exterior sideof the building, a 14” (356 mm) and 36” (914 mm) Snorkel Termination (ST) is available. Follow the installation
procedures for horizontal terminations. If the snorkel
termination is to be located below grade, a window wellis recommended with adequate and proper drainage
as per local codes. Leave 2” (51 mm) clearance below snorkel to prevent water from entering the snorkel
termination. Do not enclose the snorkel within a wall orother type of enclosure and do not back fill. Ensurethat grade level slopes away from the building. (Fig. 40)

1. Determine the location of the appliance. Choose
a location which provides adequate clearance fromobstacles such as electrical wiring, conduit, framing
members, plumbing pipe, etc.
2. After positioning the appliance, determine where thevent pipe will pass through the ceiling. This can be doneby using a plum bob or a small weight attached to astring. Hold the plum bob from the ceiling moving it until
it lines up with the centerline of the outlet of the appliance. Mark the position on the ceiling.
NOTE: Frame openings to the dimensions specified
in the framing table for the cathedral ceiling support
box (CCS), the ceiling support (SC) and wherever thefirestop spacer (FS) is being used.
3. Cut and frame the appropriate sized square holethrough the ceiling. Repeat the process for other ceiling
penetrations as necessary.
4. Determine and mark the roof penetration in thesame manner.
5. Cut a hole in the roof at this point large enough tosatisfy all clearance-to-combustible requirements as
specified by the appliance manufacturer’s installation
instructions.
6. Install the ceiling support cathedral ceiling support

the assembled pipe to the appliance. Determine andmark the location of where the support collar will be attached to the pipe. Disconnect and remove assembled
pipe. Attach the support collar per Step 10 (where
marked) and reinstall assembly. This is due to limited
space within the cathedral ceiling support box. Install
any required offset supports.
11. Add lengths of pipe and firestop as necessary
until assembly extends to a point above the roof which
complies with local code requirements for minimum termination height and with the appliance manufacturer’s

Your First Fire
Read these instructions carefully and familiarize
yourself with the burner controls shown on Page 31.
Locate the pilot assembly, Figure 53. Follow the lighting
instructions on Page 31 exactly.
During the first fire, it is not unusual to smell someodor associated with new logs, paint and metal being
heated. Odors should dissipate within the first eight toten hours, however, you can open a window to provide
fresh air to alleviate the condition.

Pilot and Burner Inspection
Each time you light your heater check that the pilot
flame and burner flame patterns are as shown in Figure
56. If flame patterns are incorrect, turn the heater off.
Contact your dealer or a qualified gas technician for assistance. Do not operate the heater until the pilot flame
is correct.

With the control knob in the pilot position, push thecontrol knob all the way and hold. Check for spark atelectrode and pilot. If no spark to pilot, and electrodewire is properly connected, replace the battery in theignitor module and try again. Refer to Maintenance
Section. If the problem still exists, replace the ignitor
module box.

A. Defective pilot generator (thermocouple), remote wall switch

Check pilot flame. Must impinge on thermocouple/thermopile. NOTE: This pilot burner assembly utilizes botha thermocouple and a thermopile. The thermocouple
operates the main valve operation (On and Off). Clean
and or adjust pilot for maximum flame impingement on
thermopile and thermocouple.

B. Defective automatic valve

Turn valve knob to “Pilot”. Maintain flow to pilot; millivolt
meter should read greater than 10mV. If the reading
is okay and the pilot does not stay on, replace the gas
valve. NOTE: An interrupter block (not supplied) must
be used to conduct this test.

A. Wall switch or wires defective

Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burnercomes on, replace defective wall switch.. If okay,
jumper wires across wall switch wires at valve, if burnercomes on, wires are faulty or connections are bad.

B. Thermopile may not be generating sufficient millivoltage

1. Be sure wire connections form thermopile at gas
valve terminals are tight and thermopile is fully
inserted into pilot bracket.
2. One of the wall switch wires may be grounded. Remove wall switch wires form valve terminals if pilot
now stays lit, trace wall switch wiring for ground.
May be grounded to fireplace or gas supply.
3. Check thermopile with millivolt meter. Take readingat thermopile terminals of gas valve. Should read
250-300 millivolts (minimum 150) while holding
valve knob depressed in pilot position and wall
switch “Off”. Replace faulty thermopile if reading is
below specified minimum.

C. Plugged burner orifice

Check burner orifices for debris and remove.

D. Defective automatic valve operator

Turn valve knob to “On”, place wall switch to “On”
millivolt meter should read greater than 150mV. If thereading is okay and the burner does not come on,
replace the gas valve.

A. Pilot flame may be too low or
blowing (high) causing the pilot
safety to drop out

Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.

B. Possible blockage of the ventterminal

Check the vent terminal for blockage (recycling the fluegases).

Radiance® Direct Vent Gas Heater

MaintenanceYour Radiance Gas Heater will provide years of service
with minimal upkeep. The following procedures will help
ensure that your stove continues to function properly.

Annual System Inspection
Have the entire heater and venting system inspectedannually by a qualified gas technician. Replace any
worn or broken parts.

Cleaning the GlassWARNING: Allow the glass to cool completely before attempting to clean.

 7!2.).'(/4 ',!33 7),,#!53% "52.3

Logset and Burner /Cleaning and Inspection
Cleanliness is critical to the proper function of theheater. The logset and burner must all be kept free of
dust and unobstructed by debris. Inspect these areas
before each use and clean as necessary.
1. Turn the burner OFF and let the heater cool completely before cleaning.
2. Lift the Stove Front up and then swing the bottom
out to disengage it from the heater shell. (Fig. 83)
3. Carefully remove the glass and frame assemblyand place it out of the way on a flat, padded surface
such as a counter protected by a towel.
4. Carefully inspect the Logs for damage. Contact yourlocal dealer if any damage is evident.
5. Use a soft bristled brush to sweep dust or debris
from the Logs, Pilot and Burner. Use care as thelogs are fragile and susceptible to damage.
6. Replace the glass panel and frame assembly.
7. Replace the Stove Front.

Care of Cast Iron
An occasional dusting with a dry rag will help keep the
painted surfaces looking new. Use high-temperature
stove paints, available through your local dealer, totouch-up areas as needed. Clean areas to be painted
with a wire brush and be sure to cover the logs, burnerand valve assembly, glass and frame assembly. Apply
the paint sparingly; two light coats of paint will give better results than a single heavy coat.

It will be necessary to clean the glass periodically. During start-up, condensation, which is normal, forms on
the inside of the glass and causes lint, dust and otherairborne particles to cling to the glass surface. Also
initial paint curing may deposit a slight film on the glass.
It is therefore recommended that the glass be cleaned
two or three times with a non-ammonia householdcleaner and warm water (we recommend gas fireplace
glass cleaner). After that the glass should be cleaned
two or three times during each heating season depending on the circumstances present.
Clean glass after first two weeks of operation.

Glass Replacement
Replace glass only with MHSC approved parts. Refer toPage 44 for Replacement Parts. Refer to Figure 84 andprevious instructions for removal of the damaged glass
frame.

Clean porcelain enamel surfaces with a soft, damp
cloth. Do not use abrasive cleaning agents. If necessary, use only a cleaning agent formulated especiallyfor use on porcelain enamel surfaces.

CAUTION
TURN THE PILOT OFF BEFORE PAINTING.
ALLOW THE HEATER TO COOL COMPLETELYBEFORE PAINTING.

Gasket Replacement
ST141

The Radiance Gas Heater usesa ‘tadpole’
type gasket
pull glass
latch
10/99 and the frame. In time,to seal between the glass panel
this gasket can become brittle and compressed andshould be replaced. New gasket is available from yourdealer.
Shut off the gas supply and allow the stove to cool.
Wear safety goggles and a dust mask.
1. Remove the Front, Glass Frame and Glass Panel.
(Figs. 83 & 84) Remove the old gasket. Use arazor blade to separate the glass and gasket fromthe frame, and to clean the glass of any remaining
cement or bits of gasket. Use a cold chisel if necessary.
2. Determine the correct length of gasket by laying it
out around the edge of the glass. Allow an extra 1- 2” (25-50mm). Mark the spot to be cut. Use a utility
knife.
3. Starting on a long edge, remove about 6” of theprotective paper strip and apply the flat adhesive
face of the gasket around the outside-facing edgeof the panel. Continue around the panel,
Figure 87
applying about 6” at a time and being
careful to not stretch the material. Do not
overlap the gasket ends. (Fig. 85)
4. Apply a thin bead of high temperaturesilicone rubber sealant along the inside

corner of the glass
frame, all around the perimeter.
ST179
Place the flat gasketed side of the glass panel backglass gasket detail
into the steel frame. Pinch the rounded inside-facing
11/99
gasket material
to bulk it up.
5. Replace the glass frame and front panel as previously described.

Inspect the Vent System Annually
Have the vent system inspected annually by a qualified technician. Shut off the main gas supply before
inspecting the system. Both the inner exhaust pipe andthe outer combustion supply pipe must be checked toconfirm that they are unblocked and in good condition.

Check the Gas Flame Regularly
To ensure that the stove is operating properly, checkthe flames periodically to confirm they match Figure 86.
The flames will be blue during the first 15-20 minutes ofoperation, and will gradually turn to yellow after that.
Do not use your stove if the flame pattern differs fromthat shown here. Contact your Vermont Castings dealer
or a qualified technician for help.
