Radiance Direct Vent /Natural Vent Gas Heater

Installation & Operating Instructions

The Radiance Direct Vent/Natural Vent Room Heater, Model
Nos. 3350 thru 3354, 3360 thru 3369 and 3390 thru 3399, is a
vented gas appliance listed to the ANSI standard Z21.88b-2002
and CSA-2.33b-2002 for Vented Room Heaters, and CSA 2.17­M91, Gas-Fired Appliances For Use at High Altitudes.

The installation of the Radiance Direct Vent/Natural Vent
Room Heater must conform with local codes, or in the absence
of local codes, with National Fuel Gas Code, ANSI Z223.1/NFPA
54 — latest edition and CSA B-149.1 Installation Code. (EX
CEPTION: Do not derate this appliance for altitude. Maintain
the manifold pressure at 3.5 inches w.c. for Natural Gas and
10 inches w.c. for LP gas at maximum input.) Refer to Page
30 (RF only).

This appliance is only for use with the type of gas indicated
on the rating plate. This appliance is not convertible for use with
other gases unless a certified kit is used.

Installation and replacement of gas piping, gas utiliza­tion equipment or accessories, and repair and servicing of
equipment shall be performed only by a qualified agency.
The term “qualified agency” means any individual, firm,
corporation, or company that either in person or through
a representative is engaged in and is responsible for (a)
installation or replacement of gas piping, or (b), the con­nection, installation, repair, or servicing of equipment, who
is experienced in such work, familiar with all precautions
required, and has complied with all the requirements of the
authority having jurisdiction.

The Radiance Direct Vent/Natural Vent Room Heater
should be inspected before use and at least annually by a
qualified service agency. It is imperative that control com
partments, burners, and circulating air passageways of the
appliance be kept clean.

The Radiance Direct Vent/Natural Vent Room Heater and
its individual shut-off valve must be disconnected from the gas
supply piping during any pressure testing of that system at test
pressures in excess of 1/2 psig (3.5 kPa).

The Radiance Direct Vent/Natural Vent Room Heater must
be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing of
the gas supply piping system at test pressures equal to or less
than 1/2 psig.

An accessible tap is located above the pilot/On-Off knob for
checking the inlet pressure.

‘Direct Vent’ describes a sealed combustion system in which
incoming outside air for combustion and outgoing exhaust enter
and exit through two separate concentric passages within the
same sealed vent system. The system does not use room air
to support combustion. The Direct Vent system permits the
gas appliance to be vented directly to the outside atmosphere
through the side of the house or vertically through the roof.
Conventional venting systems (Natural Vent) take air from the
room for combustion and vent the exhaust vertically through the
roof to the atmosphere.

This appliance is approved for bedroom installations in the
U.S. and Canada. Check local codes for natural vent require
ments.

This appliance may be installed in an aftermarket* manu­factured (mobile) home, where not prohibited by state or local
codes.

WARNING: Operation of this heater when not connected
to a properly installed and maintained venting system can
result in carbon monoxide (CO) poisoning and possible
death.

The Radiance Direct Vent/Natural Vent Room Heater, when

-

installed, must be electrically grounded in accordance with lo
cal codes or, in the absence of local codes, with the National
Electrical Code ANSI/NFPA 70, (latest edition), or of the current
Canadian Electrical Code C22.1.

Due to high temperatures this appliance should be located

out of traffic and away from furniture and draperies.

WARNING: This appliance is hot while in operation. Keep
children, clothing, and furniture away. Contact may cause
burns or ignition of combustible materials.

Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and
any gas control which has been under water.

Do not burn wood, trash or any other material for which
this appliance was not designed. This appliance is designed
to burn either natural gas or propane only.

This gas appliance must not be connected to a chimney
flue serving a separate solid-fuel burning appliance.

CAUTION: Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangerous operation.

Verify proper operation after servicing.

* Aftermarket: Completion of sale, nor for purpose of resale,

Vertical Termination - Direct Vent ONLY

A vertical vent system must terminate no less than 8’
(2.44m) and no more than 40’ (12m) above the appli­ance flue collar. A 2¹⁄₄" 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. Install restrictor plate supplied with
stove directly at stove outlet. A vertically terminated

vent system must also conform to the following criteria:

• 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.

• Vent must rise a minimum of 2 feet before offset is

used.

• Termination height must conform to roof clearance

as specified in Figure 9.

All Vertical Termi­nations in this area
Require use of
the 2¹⁄₄” Restrictor
Plate*

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 9.

Important: All vent clearances must be maintained.
Check your vent termination clearances against
Figures 9 through 11.

The vent should be placed so that people cannot be
burned 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 away
from 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 interfere

with 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 the
family members gather most regularly, and perhaps
most importantly, the distance limitations of the venting
system.

IMPORTANT
Direct Vent Only

• 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 Hori­zontal Vent Cap straps to the vent pipe. See the
maker’s instructions for recommended installa­tion procedures.

ST132a

20004188

Radiance Direct Vent /Natural Vent Gas Heater

Vent Termination Clearances

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.

• Only CFM Corporation and Simpson DuraVent

venting components specifically approved and
labelled for this stove may be used.

• Minimum clearances between vent pipes and

combustible materials is one (1”) inch (25 mm),
except where stated otherwise.

• 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.

Do not locate termination hood where excessive snow
or 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 vent
termination area.

Location of Vent Termination

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

CEMENT

The Radiance stove, when installed as a Natural vent
heater, includes a vent safety switch. (Page 34, Figure

67) Operating the stove when it is not connected to a
properly installed and maintained venting system, or
tampering with or disconnecting the vent safety switch,
can result in carbon monoxide (CO) poisoning and
possible death.

For U.S. installations: The venting system must
conform with local codes and/or the current National
Fuel Gas Code, ANSI Z22.1.

For Canadian installations: The venting system must
conform to the current CSA B149.1 installation code.

Install the Vent Pipe

Apply a bead of sealant around bottom end of inner
starter pipe (found in bag with logset) and attach to
stove. Apply a bead of sealant around top of inner
starter pipe and install the Z31D00 FSDHAG Draft
Hood according to Draft Hood instructions. (Fig. 35)

Attach the first section of venting to the draft hood.
Depending on the length of the individual venting
sections and the lengths of the decorative pipe (if
installed), you may need to slip the decorative pipe over
the venting sections before attaching upper sections
to lower ones. The sections of decorative pipe should
be oriented with their seams (if any) toward the wall;
sections usually do not need to be fastened at each
joint, other than slip sections. If the layout includes
a slip section, this should be the last section of pipe
visible in the room, at the ceiling. Complete the venting
according to the vent maker’s instructions.

Install Log Set

Before beginning log installation, remove stove front
and glass frame. Refer to Figures 36 and 37.

SYMPTOM

POSSIBLE CAUSES

CORRECTIVE ACTION

1. Spark ignitor will
not light

2. Pilot will not stay lit
after carefully fol­lowing the lighting
instructions

3. Pilot lights, no gas
to burner, valve
knob ON, remote
switch (rocker

A. Remote switch or wires

defective

B. Thermopile may not gener

ate sufficient voltage

Using a match, light pilot. If pilot lights, turn off pilot and
push the ignitor button again. If pilot will not light, check
gap at electrode and pilot - it should be 1/8” to have a
strong spark.

Push piezo ignitor button. Check for spark at electrode
and pilot. If there is no spark at the pilot, and electrode
wire is properly connected, replace ignitor.

Check pilot flame. It must impinge on the thermocouple
or thermopile. NOTE: This pilot burner assembly uses
both a thermocouple and a thermopile. The thermocou
ple operates the pilot flame. Tighten the thermocouple.
The thermopile operates the main valve (ON and OFF).
Clean and/or adjust pilot for maximum flame impinge­ment on thermocouple and thermopile.

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 rocker switch and wires for proper connection.
Use jumper wires across terminals at rocker switch. If
burner lights, replace rocker switch. If okay, use jumper
wires across rocker switch wires at the valve; if burner
lights, wires are faulty or connections are bad.

-

1. Be sure wire connections from thermopile at gas valve
terminals are tight and thermopile is fully inserted into
pilot bracket.

-

4. Frequent pilot out­age

20004188

C. Plugged burner orifice

D. Defective automatic valve

operator

A. Pilot flame may be too low

or high, (blowing or lifting),
causing the pilot to drop out

B. Possible blockage of the

vent terminal

2. One of the rocker switch wires may be grounded.
Remove rocker switch wires from valve terminals. If
burner now stays lit, trace rocker switch wiring from
ground. It may be grounded to the appliance or the
gas supply line.

3. Check the thermopile with a millivolt meter. Take read
ing at thermopile (“TP” and “TP/TH”) terminals of gas
valve. Should read 325 millivolts minimum while hold­ing valve knob depressed in PILOT position and with
rocker switch OFF. Replace faulty thermopile if reading
is below specified minimum.

Check burner orifices for debris, and remove.

Turn knob to ON, place rocker switch to ON, millivolt me­ter should read greater than 10 mV. If the reading is okay
and the burner does not light, replace the valve.

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

Check the vent terminal for blockage.

Radiance Direct Vent /Natural 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.

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.

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. 62)

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.

6. Replace the glass panel and frame assembly.

7. Replace the Stove Front.

-

CAUTION

TURN THE PILOT OFF BEFORE PAINTING.
ALLOW THE HEATER TO COOL COMPLETELY
BEFORE PAINTING.

Cleaning the Glass

WARNING: Allow the glass cool completely before
attempting to clean.

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 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 depend­ing on the circumstances present.

Clean glass after first two weeks of opera
tion.

Glass Replacement

Replace glass only with CFM Corporation approved
parts. Refer to Page 35 for Replacement Parts. Refer to
Figure 63 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 bet­ter results than a single heavy coat.

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

for use on porcelain enamel surfaces.

Fig. 64 Wrap the gasket material around the outside edge of

Fig. 63 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.

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. 62 & 63) 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 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 the pro
tective paper strip and apply the flat adhesive face
of the gasket around the outside-facing edge of the
panel. Continue around the panel, applying a bout 6”
at a time and being careful to not stretch the mate­rial. Do not overlap the gasket ends. (Fig. 64)

4. Apply a thin bead of high temperature silicone
rubber sealant along the inside 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.

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 quali­fied 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.

Check the Gas Flame Regularly

To ensure that the stove is operating properly, check
the flames periodically to confirm that they match
Figure 65. The flames will be blue during the first 15-20
minutes of operation, and will gradually turn to yellow
after that.

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.
