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
between fixed low and high settings, alter-
nately, while the appliance is in operation.
Adjust the flame height as desired after light-
ing the appliance by rotating the variable
adjustment control knob located on the front
of the valve
(refer to Figure 2). (An extension
is provided to this knob so that the adjustment
may be made at the modesty panel.)
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.

Millivolt Appliances -
To light millivolt appliances refer to the de-
tailed lighting instructions found on
page 11
(English) and page 12 (French). Millivolt ap-
pliance lighting 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.
Electronic Appliances -
To light electronic appliances refer to the
detailed lighting instructions found in both
English and French on
pages 13 and 14 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.
Electronic 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 op-
eration. To operate: Toggle the switch be-
tween its ON and OFF positions.
Remove the bottom compartment door by
sliding the hinge pin, located at the door’s left
side, to the right until it disengages from the
left corner post hole. Pull the door diagonally
to the left, away from the fireplace.
Once the control compartment door has been
removed, the modesty panel can be removed
as follows: slide the modesty panel forward
until it contacts the cabinet bottom panel, then
lift straight up and tilt forward. Remove the
modesty panel carefully, so that none of the
wires become loose or disconnected. Now
complete access to the gas control valve and
its related controls is attainable.
To ease door closure, depress the catches to
place them in their retracted position until they
stay there, then close the door.
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.
