Glass Enclosure Panels - Removal and
Installation.
These are direct-vent appliances. They are de-
signed to operate only with the glass enclosure
panels properly installed. Generally the glass
enclosure panels should not be removed ex-
cept to gain access to the components within
the firebox, and the appliance may only be
operated without the front glass enclosure panel
in place for very brief periods of time during
initial appliance checkout and adjustment.
During this appliance checkout and adjust-
ment period, a potential safety hazard exists
- EXERCISE EXTREME CAUTION to prevent the
occurrence of any burn injuries from the ex-
posed flames or hot surfaces. Also note, that
while the front glass enclosure panel (or any of
the panels) is removed, the flame appearance
will appear to be smaller than normal.
CAUTION: DO NOT TOUCH THE FRONT
ENCLOSURE GLASS WITH YOUR HANDS
WHILE THE FIREPLACE IS IN USE.
Electronic Appliances -
To light electronic appliances refer to the de-
tailed lighting instructions found in both En-
glish and French on
pages 14 and 15
of these
instructions respectively. Electronic appliance
lighting instructions may also be found on the
pull out lighting instruction labels attached to
the gas control valve.
If your electronic appliance is equipped with an
optional remote wall switch or remote control
kit the appliance main burner may be turned on
and off with the wall switch or remote control.
If your electronic appliance is not equipped
with a wall switch or remote control, the main
burner must be turned off and on with the gas
control switch. Toggle the switch from ON to
OFF to operate the main burner.

Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at
least annually by a qualified service techni-
cian. However, more frequent periodic inspec-
tions and cleanings should be performed by
the homeowner. Homeowner must contact a
qualified service technician at once if any
abnormal condition is observed.
Refer to the maintenance schedule for mainte-
nance tasks, procedures, periodicity and by whom
they should be performed. Always verify proper
operation of the appliance after servicing.
IMPORTANT: TURN OFF GAS AND ANY
ELECTRICAL POWER BEFORE SERVICING
THE APPLIANCE.
2. When lit for the first time, this appliance will
emit a slight odor for 14 hours. This is due to the
“burn-in” of internal paints and lubricants used in
the manufacturing process.
3. Keep lower control compartment clean by
vacuuming or brushing at least twice a year.
More frequent cleaning may be required due to
excessive lint from carpeting, bedding materi-
als, etc. It is important that control compart-
ments, burners and circulating air passage-
ways of the appliance be kept clean.
4. Always turn off gas to the pilot (millivolt
appliances) and let the unit cool down before
cleaning. Before re-lighting, refer to the light-
ing instructions in this manual. Lighting in-
structions may also be found on the pull out
lighting instruction labels attached to the
gas control valve.
5. Always keep the appliance area clear and
free from combustible materials, gasoline and
other flammable liquids.
6. Remember, Millivolt appliances have a con-
tinuous burning pilot flame. Exercise caution
when using products with combustible vapors.
Glass Cleaning
It will be necessary to clean the glass periodi-
cally. During start-up it is normal for conden-
sation to form on the inside of the glass. This
can cause lint, dust and other airborne par-
ticles 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 (a
gas fireplace glass cleaner is recommended).
After that the glass should be cleaned two or
three times during each heating season, de-
pending on the circumstances present.

Variable Flame Height Adjustment
( Millivolt Appliances only)
1. All Millivolt appliances are equipped with a
variable gas control valve. Flame height for these
models may be adjusted through a range be-
tween fixed low and high settings while the
appliance is in operation. Adjust the flame height
as desired after lighting the appliance by rotating
the variable adjustment control knob located on
the front of the valve
(refer to Figure 2)
