electronic appliances -
To light electronic appliances refer to the detailed
lighting instructions found in both English 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. See Figure 1 for its location.
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.
Variable Flame Height adjustment
(Millivolt and electronic appliances)
. All Millivolt and Electronic appliances are
equipped with a variable gas control valve. Flame
height for these models may be adjusted through
a range between fixed low and high settings,
alternately, 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).
2. When lit for the first time, this appliance will
emit a slight odor for an hour or two. 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 materials,
etc. It is important that control compartments,
burners and circulating air passageways of the
appliance be kept clean.
. Always turn off gas to the pilot (millivolt
appliances) before cleaning. Before re-lighting,
refer to the lighting instructions in this manual.
Instructions are also found on a pull-out panel
located on the floor of the appliance.
Maintenance
The appliance and venting system should be
thoroughly inspected before initial use and at least
annually by a qualified service technician. However,
more frequent periodic inspections and cleanings
should be performed by the homeowner.
Homeowner must contact a qualified service
technician at once if any abnormal condition
is observed.
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 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-ammo-
nia 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, depending
on the circumstances present.
note: Clean glass after first two weeks of
operation.

Gas controls/control compartment access
The gas controls can be found behind the bottom
panel. Remove the bottom panel by pulling it
towards the front.
On millivolt systems, the piezo ignitor, Hi/Lo
flame adjustment knob, and pilot and main
gas ON/OFF control knob are located behind
the panel. See Figure 1.
Operation of millivolt and electronic gas con-
trol systems are different. Before lighting and
operating your appliance determine if you have
a millivolt or electronic appliance.
Refer to Figure 1 for access to the gas control
valve. Millivolt appliances will be fitted with the
gas control valve shown in Figure 2.
Appliances with electronic systems will be fitted
with the electronic valve shown in Figure 3.
Familiarize yourself with the gas control valve
that your appliance uses.
Millivolt appliances -
To light millivolt appliances refer to the detailed
lighting instructions found on page 12 (English)
and page 13 (French). Millivolt appliance light-
ing instructions may also be found on the pull
out lighting instruction labels attached to the
gas control valve.
Millivolt appliances are fitted with an ON/OFF
Rocker Switch for appliance ON/OFF control.
See Figure 1 for its location. Once the pilot is
lighted, the ON/OFF rocker switch will control the
appliance ON/OFF operation. To operate: Toggle
the switch between its ON and OFF positions.
If your millivolt appliance is equipped with an
optional remote wall switch or remote control
kit and the pilot is lit, the appliance main burner
may be turned on and off with the wall switch
or remote control.
