The installation of your Radiance stove must conform
with local codes, or in the absence of local codes,
with the National Fuel Gas Code ANSI Z223.1/NFPA
54 - latest edition. (EXCEPTION: Do not derate this
appliance for altitude up to 4,500 feet (1,370 m).
Maintain the manifold pressure at 3.5” w.c. for Natural
Gas and 11.0” w.c. for LP Gas.
Neither natural gas nor propane gas give off an odor
when burned. The nature of a vent free combustion
system, however, is such that odors may occasional-
ly be produced during heater operation when impuri-
ties exist in the immediate area. Cleaning solutions,
paint, solvents, cigarette smoke, candles, adhesives,
new carpet or textiles, etc., all can create fumes.
These fumes may mix with combustion air and can
create odor. Such odors will disappear over time,
however the condition can be alleviated by opening a
window or otherwise providing additional ventilation
to the area.

Radiance® Vent-Free Gas Heater

The Radiance Vent Free stove, is an unvented gas
heating appliance tested and listed to the ANSI stan-
dard Z21.11.2 Latest Edition. This appliance is speci-
cally congured to burn either Natural Gas or Propane
fuel, as indicated on the metal rating plate attached to
the rear shroud. The Radiance Vent Free is not fuel
convertible.
The stove is shipped fully assembled with the exception
of the log set. The log set is assembled during installa-
tion.
The stove is equipped with an SIT control valve that
allows thermostatic control, on/off switch or a remote
switch (not supplied).
The stove model incorporates variable regulators that
allow you to adjust burner heat output between HIGH,
(35,000 Btu), and LOW, (26,000 Btu). See the Opera-
tion Section for details.
A push button Piezo ignitor is used to light the stand-
ing pilot. The pilot incorporates an Oxygen Depletion
System (ODS/pilot) which will shut off gas ow to the
burner in the event that sufcient fresh air becomes
unavailable for continued safe operation.
Modern construction standards have resulted in homes
that are highly energy-efcient and that allow little heat
loss. Your home needs to breathe, however, and all
fuel-burning appliances within it require fresh air in
order to function properly and safely. Exhaust fans,
clothes dryers, replaces, and other fuel burning appli-
ances all use the air inside the building. If the available
fresh air is insufcient to meet the demands of these
appliances, problems can result.
The Radiance Unvented heater has specic fresh air
requirements.
The following informa-
tion will help you insure that adequate fresh air is avail-
able for the heater to function properly.

be performed only by a qualied gas technician who
should also verify that adequate ventilation is available
to support proper burner function.
Installation of optional accessories, such as the Fan,
Glass/Catalyst, or thermostat, is most easily accom-
plished before the gas supply connection is made.

It is easiest to install the optional fan kit #2767/FK26,
before the stove is moved to its nal location or con-
nected to the gas line.
The fan consists of a blower assembly and a rheo-
stat switch that are connected by a wire harness. The
blower attaches to a bracket at the bottom of the rear
shroud. The rheostat installs at the bottom of the stove
on the left of the valve.
The fan kit includes a ‘snapstat’, a temperature-sens-
ing switch which will be mounted to the blower duct just
below the top plate of the stove. The snapstat automati-
cally turns the fan on or off at approximately 109° F.
The rheostat provides a range of fan speed settings
from OFF (which overrides the snapstat function) to
high.
• Fan assembly with rheostat and snapstat
• wire tie • control knob • retaining collar
Sheet metal edges can be sharp. Be sure to
wear protective gloves.
1. Loosen the four phillips head screws which secure
the rear shroud to the stove sides. (Fig. 8)
2. Carefully pull the shroud assembly away from the
rear of the stove.
3. With the rear shroud assembly in the upright posi-
tion, set the bottom of the shroud on a padded surface
to prevent scratching the surface. Unfasten the four
phillips head screws which attach the outer shroud to
the inner duct assembly.
1. Slide stove to the rear of the pallet just far enough to
access rear leg holes. Make sure the stove does not
tip over backwards. (Fig. 6)

Read these instructions carefully and familiarize your-
self with the burner controls shown on Page 17. Locate
the pilot assembly, Figure 29. Follow the lighting instruc-
tions on Page 16 exactly.
During the rst re, it is not unusual to smell some odor
associated with new logs, paint and metal being heated.
Odors should dissipate within the rst eight to ten hours,
however, you can open a window to provide fresh air to
alleviate the condition.
Each time you light your heater check that the pilot
ame and burner ame patterns are as shown in Figure
31 and Figure 32. If ame patterns are incorrect, turn
the heater off. Contact your dealer or a qualied gas
technician for assistance. Do not operate the heater
until the pilot ame is correct.
For units equipped with HI/LO valves, the ame adjust-
ment is accomplished by rotating the HI/LO adjustment
knob located near the center of the gas valve. (Fig. 30)

The following procedures will help ensure that your
heater continues to perform safely and efciently.
Follow the simple procedure outlined below.
Frequent cleaning may be necessary in living environ-
ments subject to excessive carpet lint or pet hair. For
example, if you live with a dog that sheds continuously,
you will need to inspect the burner area frequently and
clean it as often as the accumulation requires.
Turn the burner OFF and let the heater cool com-
pletely before cleaning.
Lift the Front plate up and then swing the bottom out
to disengage it from the heater shell. (Page 8, Fig.
4)
Remove the screen by lifting up and away from the
unit. Or, if so equipped, remove the glass panel by
releasing the two upper retainer latches. Lift the
panel up and off of the rebox frame. (Fig. 33)
Carefully inspect the log set for damage. Contact
your local dealer if any damage is evident.
Use a soft-bristled brush vacuum cleaner attach-
ment to remove dust or debris from the log set, pilot
and burner. Use care as the log set is fragile.
Inspect the catalytic combustor at the top of the
rebox. Replace the combustor if any damage or
deterioration is evident.
Replace the screen or glass panel and the front
plate.
If so equipped, do not operate this appliance with the
glass panel cracked, broken, or removed. Replace
damaged glass only with Vermont Castings Group ce-
ramic glass panel Part No. 1601290. Follow the Clean-
ing Procedure instructions regarding parts removal.
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 log set,
burner and valve assembly. Apply the paint sparingly;
two light coats of paint will give better results than a
single heavy coat.
Porcelain enamel surfaces should be cleaned with a
soft, damp cloth. Do not use abrasive cleaning agents.
If necessary, use only a cleaning agent formulated spe-
cically for use on porcelain enamel surfaces.
Remove the screen or glass panel.
