Vertical Termination

A vertical vent system must terminate no less than 8’

(2.44 m) and no more than 40’ (12 m) above the ap-

pliance ﬂue collar. A restrictor plate (supplied) must be

used, where speciﬁed, in all vertically terminated vent

systems. (Refer to Figure 8) NOTE: The restrictor

plate supplied with the vertical termination should

be discarded. Adjust the restrictor plate according

to recommendations in Figure 10. A vertically termi-

nated vent system must also conform to the following

criteria:

The Radiance stove is shipped with a restrictor plate

in the Parts Bag. Adjustments can be made by loosen-

ing the adjustment screw to allow the restrictor plate to

slide up or down. (Fig. 9) A guide for usage is shown in

Figure 10.

NOTE: Some installations may require some adjust-

ment by the installer for optimum ﬂame appearance.

Optimum ﬂame appearance is a ﬂame that is not sub-

ject to tall, dirty yellow ﬂames producing soot or ﬂames

lifting off of the ember bed ports.

• No more than three 90° elbows may be used.

• Two 45° elbows may be substituted for one 90˚

elbow. No more than six 45° elbows may be used.

Restrictor Plate Adjustment

1. Remove the screw in the back wall of the ﬁrebox.

• Vent must rise a minimum of 2 feet (305 mm) before

offset is used.

2. Install restrictor plate as shown in Figure 9 with cut

out on left side. Secure with adjustment screw.

• Termination height must conform to roof clearance

as speciﬁed in Figure 11.

Radiance Direct Vent Gas Heater

Vent Termination Clearances

When planning the installation, consider the location

of the vent terminal and clearances. Some of the most

common clearances to keep in mind are shown in Figure

11.

Your stove is approved to be vented either through the

side wall, or vertical through the roof.

• CFM Corporation does not require any opening

for inspection of vent pipe.

Important: All vent clearances must be maintained.

Check your vent termination clearances against

Figures 11 through 13.

• Only CFM Corporation, Simpson DuraVent and

Selkirk Corporation venting components speciﬁ-

cally approved and labelled for this stove may be

used.

The vent should be placed so that people cannot be

burned by accidentally touching the vent surfaces when

the stove is operating.

• Minimum clearances between vent pipes and

combustible materials is one (1”) inch (25 mm),

except where stated otherwise.

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 away

from areas where it could become blocked by snow,

etc.

• Venting terminals shall not be recessed into a wall or

siding.

• 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.

Some considerations are:

• Obstructions or impediments to venting.

• Nearby combustible materials that could come into

contact with combustion exhaust gases.

Do not locate termination hood where excessive snow

or ice build up may occur. Be sure to check vent termi-

nation area after snow falls, and clear to prevent ac-

cidental blockage of venting system. When using snow

blowers, make sure snow is not directed towards vent

termination area.

• Other nearby openings {within 12” (305 mm)}

through which exhaust gas could reenter the build-

ing.

• All vegetation within 3’ (76 mm) that may interfere

with the draft.

Location of Vent Termination

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 the

family members gather most regularly, and perhaps

most importantly, the distance limitations of the venting

system.

It is imperative the vent termination be located observ-

ing 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 the

vent 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 Hori-

zontal Vent Cap straps to the vent pipe. See the

maker’s instructions for recommended installa-

tion procedures.

The pipe and elbows are assembled by inserting the

outlet (male) end of a length of pipe or elbow into the in-

let (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. Push

in the Lock Tab such that it becomes seated within the

inward groove of the adjoining section. This locks the

joint in place. (Fig. 34)

The Cathedral Ceiling Support (CCS) may be used in

pitched or ﬂat ceiling installations and comes with a

support collar and a decorative two part square trim

plate. Install by inserting the support box down through

the framed joist opening (end with round hole ﬁrst) in

the ceiling using tin snips, cut the corners of the open

end of the box such that the sides can be folded down

over the top of the joist framing members. Nail the

folded sides to the top of the framing. (Fig. 37)

Supporting DIRECT-TEMP: Horizontal Support

Horizontal runs of Direct-Temp should be supported

every 4’ (122 cm) of pipe. This can be done with the use

of plumbers strapping or the offset support.

Adjustable Length (AJ)

An Adjustable Length is available to accommodate

installations where non-standard lengths are necessary.

The adjustable length telescopes down over a standard

length of pipe and provides an extension range of 3¹⁄₂”

(89 mm) to 10¹⁄₂” (267 mm). Install by sliding the inlet

end of the adjustable length over the outlet end of a

standard length of pipe. After positioning the adjustable

length appropriately, secure it to the standard length

with two (2) #8 x1/4” sheet metal screws (provided).

Seal the area between both the top and bottom of the

adjustable length outer wall and the outer wall of the

standard length with an approved silicone sealant.

Fire Stopping

DIRECT-TEMP must be ﬁrestopped wherever it passes

through ﬂoors, ceiling or walls. The only location where

a ﬁrestop is not required is at the roof level. Both verti-

cal support components with trim plates provide for

ﬁrestopping. The wall thimble also acts as a ﬁrestop.

AT other locations, a ﬁrestop spacer (FS) should be

installed. In the attic the ﬁrestop should be placed on

top of the joist framing to prevent debris from falling into

the joist framing. (Fig. 39)

2. Assemble the pipe (and elbow if using) and attach it

to the appliance. Plan for a level to 1/4” per foot rise (6

mm per 305 mm) (from inlet to outlet) in the horizontal

system if not speciﬁed by the appliance manufacturer.

Horizontal runs should be supported every 4’ (122 cm).

3. Push the appliance near the desired location. Deter-

mine the centerpoint of the penetration by locating the

centerline of the outlet of the pipe with respect to the wall.

ST931

4. Frame an opening to the dimension speciﬁed in the

Framing Dimension Table 1. Ensure the centerline of

the pipe lines up with the center of the prepared open-

ing unless otherwise speciﬁed by the appliance manu-

facturer.

Fig. 42 Horizontal termination.

a Vinyl Siding Standoff (VS) must be installed prior to

installing the horizontal termination. Refer to the appli-

ance manufacturer to determine if one is recommend-

ed. Attach the vinyl siding standoff to the exterior side

of the wall (making sure it is level and centered with

respect to the opening) with screws (provided) at each

corner of the standoff. Attach the horizontal termination

to the standoff. (Fig. 43)

NOTE: As a general rule, the wall thimble is optional in

the U.S. However, there may be some manufacturers

that require it. Contact the appliance manufacturer for

information if uncertain. When installed in Canada, a

wall thimble is required on all installations in which

the vent passes through a combustible wall.

Vinyl Siding Standoff

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 thickness-

es of 4¹⁄₂” (114 mm) to 7¹⁄₂” (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 the

shields.

6. Install the horizontal termination to the exterior wall

using four (4) all purpose screws through the holes

located at each corner of the termination. Make sure

the 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 com-

bustible 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) and

screwed to the pipe or removed with a pair of tin snips

if not used. Use proper masonry fasteners to attach the

horizontal termination to the wall.

kel Termination (ST) is available. Follow the installation

procedures for horizontal terminations. If the snorkel

termination is to be located below grade, a window well

is recommended with adequate and proper drainage

as per local codes. Leave 2” (51 mm) clearance be-

low snorkel to prevent water from entering the snorkel

termination. Do not enclose the snorkel within a wall or

other type of enclosure and do not back ﬁll. Ensure

that grade level slopes away from the building. (Fig. 40)

2. After positioning the appliance, determine where the

vent pipe will pass through the ceiling. This can be done

by using a plum bob or a small weight attached to a

string. Hold the plum bob from the ceiling moving it until

it lines up with the centerline of the outlet of the appli-

ance. Mark the position on the ceiling.

7. Determine the distance from the appliance outlet to

a point just above [approximately 12” (305 mm) to 24”

(610 mm)] either the cathedral ceiling support box or

the ceiling support plate and assemble lengths of pipe

to satisfy this distance. Do not attach assembly to appli-

ance.

NOTE: Frame openings to the dimensions speciﬁed

in the framing table for the cathedral ceiling support

box (CCS), the ceiling support (SC) and wherever the

ﬁrestop spacer (FS) is being used.

8. Loosely position the support collar around the as-

sembled lengths (ﬂared end down).

9. From above, lower the assembled pipe sections

down through the cathedral ceiling box or ceiling sup-

port plate and attach it to the appliance adapter. The

support collar should then be adjusted so that when

the assembled lengths of pipe are attached to the ap-

pliance, it rests on the bottom of the cathedral ceiling

support box on top of the ceiling support plate.

3. Cut and frame the appropriate sized square hole

through the ceiling. Repeat the process for other ceiling

penetrations as necessary.

4. Determine and mark the roof penetration in the

same manner.

5. Cut a hole in the roof at this point large enough to

satisfy all clearance-to-combustible requirements as

speciﬁed by the appliance manufacturer’s installation

instructions.

10. Tighten the tabs of the collar. Secure the sup-

port collar by inserting three (3) #8 x 1/4” sheet metal

screws through the support collar and the outer wall of

the pipe.

6. Install the ceiling support cathedral ceiling support

box assembly, as appropriate.

NOTE: If the cathedral ceiling support box assembly is

being used, it may be necessary to temporarily connect

the assembled pipe to the appliance. Determine and

mark the location of where the support collar will be at-

tached 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.

NOTE: Whenever DIRECT-TEMP penetrates through a

ceiling, a ﬂoor or a wall, it must be ﬁrestopped.

12. Using a level, make sure the system is perfectly

vertical.

13. Slide the ﬂashing, suitable for the roof pitch, down

over the pipe protruding through the roof. Recheck

orientation and use a silicone sealant around and under

the perimeter of the ﬂashing where it is in contact with

the roof. Secure the ﬂashing with rooﬁng nails. Finish

rooﬁng around the pipe, covering the sides and upper

ares of the ﬂashing base with rooﬁng material. How-

ever, be sure the lower unnailed portion of the base

covers the rooﬁng material.

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 ter-

mination height and with the appliance manufacturer’s

installation instructions. (Fig. 45)

SIT NOVA 820 MILLIVOLT VALVE

NOTE: Before trouble shooting the gas control system, be sure external gas shut off is in the “On” position.

Possible Causes

Symptom

Corrective Action

1. Spark ignitor will not light

A. Defective or misaligned electrode

at pilot

Using a match, light pilot. If pilot lights, turn off pilot and

push the red button again. If pilot will not light - check

gap at electrode and pilot-should be 1/8” to have a

strong spark.

With the control knob in the pilot position, push the

control knob all the way and hold. Check for spark at

electrode and pilot. If no spark to pilot, and electrode

wire is properly connected, replace the battery in the

ignitor module and try again. Refer to Maintenance

Section. If the problem still exists, replace the ignitor

module box.

B. Defective ignitor (Push Button)

Check pilot ﬂame. Must impinge on thermocouple/ther-

mopile. NOTE: This pilot burner assembly utilizes both

a 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.

2. Pilot will not stay lit after

carefully following lighting

instructions

A. Defective pilot generator (thermo-

couple), remote wall switch

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.

Check wall switch and wires for proper connections.

Jumper wire across terminals at wall switch, if burner

7. If the manual switch is in the LOCAL position, the

valve will be at the highest ﬁxed pressure setting

and the fan will be at the highest ﬁxed speed. The

transmitter will control the fan only.

Instructions for Comfort Control Valve

RADVTC Series

The Comfort Control valve allows remote control of

temperature, fan and ﬂame appearance.

Shut Off Procedure

NOTE: The antenna should hang in free air away from

grounded metal.

If the manual switch is in the REMOTE position, the

transmitter can shut off the main burner and fan. How-

ever, the control is still on and a command from the

transmitter can turn on the main burner or fan.

Operation

1. If the manual switch is in remote position, switch it to

LOCAL. (Fig. 57)

To shut off the system, turn the pilotstat knob clockwise

to the OFF position. This action closes the main gas

and safety valves. The transmitter cannot turn on the

main burner or fan.

2. Turn the pilotstat knob counterclockwise from OFF

to the PILOT position, push the knob down, and hold

in position. The pilot valve opens and allows gas to

ﬂow to the pilot burner.

Transmitter Operation

Off Mode

3. Push plunger on the piezo until the pilot burner is lit.

When the pilot burner is lit, the LED on the control

will come on after approximately 40 seconds and

will provide 1 short blink continuously in the normal

mode. When the light turns off which will be approxi-

mately 10 seconds after it has been continuously

red, the receiver/valve is fully powered.

In the OFF mode, the ﬁreplace ﬂame and fan are

off, the display will show OFF and displays the room

temperature. If the receiver is in REMOTE mode, the

ﬁreplace will shut off.

operation is required between the receiver/valve

and transmitter. Change the switch from LOCAL

to REMOTE. Press the fan or ﬂame button on the

transmitter within 30 seconds. The LED will blink

indicating the transmitter will now work with the re-

ceiver/valve. If the switch continues in the REMOTE

position, the transmitter will now control the main

valve, ﬂame modulation level and fan control.

Delay Timer Mode

The shut off delay timer has a maximum of 2 hours and

a minimum of zero minutes. To change the timer level,

press the time key followed by an arrow key. Pushing

the key once will change the timer by 10 minutes.

Radiance Direct Vent Gas Heater

Maintenance

Your Radiance Gas Heater will provide years of service

with minimal upkeep. The following procedures will help

ensure that your stove continues to function properly.

Cleaning the Glass

WARNING: Allow the glass to cool com-

pletely before attempting to clean.

Annual System Inspection

Have the entire heater and venting system inspected

annually by a qualiﬁed gas technician. Replace any

worn or broken parts.

�

��

Logset and Burner /

��

Cleaning and Inspection

��

Cleanliness is critical to the proper function of the

heater. 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.

��

It will be necessary to clean the glass periodically. Dur-

ing start-up, condensation, which is normal, forms on

the inside of the glass and causes lint, dust and other

airborne 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 household

cleaner and warm water (we recommend gas ﬁreplace

glass cleaner). After that the glass should be cleaned

two or three times during each heating season depend-

ing on the circumstances present.

1. Turn the burner OFF and let the heater cool com-

pletely before cleaning.

2. Lift the Stove Front up and then swing the bottom

out to disengage it from the heater shell. (Fig. 76)

3. Carefully remove the glass and frame assembly

and 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 your

local 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 the

logs are fragile and susceptible to damage.

Clean glass after ﬁrst two weeks of opera-

tion.

6. Replace the glass panel and frame assembly.

7. Replace the Stove Front.

Glass Replacement

Replace glass only with CFM Corporation approved

parts. Refer to Page 43 for Replacement Parts. Refer to

Figure 77 and previous instructions for removal of the

damaged glass frame.

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, to

touch-up areas as needed. Clean areas to be painted

with a wire brush and be sure to cover the logs, burner

and valve assembly, glass and frame assembly. Apply

the paint sparingly; two light coats of paint will give bet-

ter results than a single heavy coat.

Clean porcelain enamel surfaces with a soft, damp

cloth. Do not use abrasive cleaning agents. If neces-

sary, use only a cleaning agent formulated especially

for use on porcelain enamel surfaces.

CAUTION

TURN THE PILOT OFF BEFORE PAINTING.

ALLOW THE HEATER TO COOL COMPLETELY

BEFORE PAINTING.

corner of the glass frame, all around the perimeter.

Place the ﬂat gasketed side of the glass panel back

into the steel frame. Pinch the rounded inside-facing

gasket material to bulk it up.

Fig. 77 Release the latches to remove the glass frame.

Gasket Replacement

The Radiance Gas Heater uses a ‘tadpole’ type gasket

to seal between the glass panel and the frame. In time,

this gasket can become brittle and compressed and

should be replaced. New gasket is available from your

dealer.

5. Replace the glass frame and front panel as previ-

ously described.

Inspect the Vent System Annually

Have the vent system inspected annually by a quali-

ﬁed technician. Shut off the main gas supply before

inspecting the system. Both the inner exhaust pipe and

the outer combustion supply pipe must be checked to

conﬁrm that they are unblocked and in good condition.

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. 76 & 77) Remove the old gasket. Use a

razor blade to separate the glass and gasket from

the frame, and to clean the glass of any remaining

cement or bits of gasket. Use a cold chisel if neces-

sary.

Check the Gas Flame Regularly

To ensure that the stove is operating properly, check

the ﬂames periodically to conﬁrm they match Figure 79.

The ﬂames will be blue during the ﬁrst 15-20 minutes of

operation, and will gradually turn to yellow after that.

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.

Do not use your stove if the ﬂame pattern differs from

that shown here. Contact your Vermont Castings dealer

or a qualiﬁed technician for help.

3. Starting on a long edge, remove about 6” of the

protective paper strip and apply the ﬂat adhesive

face of the gasket around the outside-facing edge

of the panel. Continue around the panel,

Figure 79

applying about 6” at a time and being

careful to not stretch the material. Do not

overlap the gasket ends. (Fig. 78)

4. Apply a thin bead of high temperature

silicone rubber sealant along the inside

Optional Accessories

Screen Kit

FK26 Fan

An optional screen, R40SK, for use with the operable

doors is available to allow the doors to be left in the

open position.

The FK26 fan helps distribute heated air from within

the ﬁrebox out into the room. The fan is controlled by a

snapstat that turns power on and off as the ﬁrebox tem-

perature rises above and falls below a preset tempera-

ture. A rheostat provides for variable fan speeds.

Warming Shelf

Warming shelves add versatility to your stove; they can

be used to keep foods warm at mealtime.

Remote Controls

The remote control allows you to turn the heater on or

off from anywhere in the room. Refer to Page 43 for

wiring diagrams. These remote controls are for use with

RN/RP models.

The shelf installation is done in three stages. First you

attach the shelf loosely to the stove, leaving the screws

loose enough to allow ﬁnal adjustments. Then, you po-

sition the shelf and adjust the brackets so the shelf ﬁts

correctly. Finally, you tighten the screws.
