OPERATION AND CARE OF yOUR
APPlIANCE
1. Appliance operation may be controlled
through a remotely located optional wall switch.
Separate switches may provide independent
control for the remote controlled fireplace
operation (optional equipment).
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
In lieu of remote or remote wall switch opera-
tion, the appliance must be operated directly
through the controls located on the front of the
valve located within the control compartment
under the removable refractory access panel,
Figure 1.

Operation of millivolt and electronic gas
control systems are different. Before lighting
and operating your appliance determine if you
have a millivolt or electronic appliance. Refer
to Figure 1 to access the gas control compart-
ment below the lower refractory panel. Millivolt
appliances will be fitted with one of the two gas
control valves shown in Figure 2. Appliances
with electronic systems will be fitted with the
electronic valve shown in Figure 3. Familiarize
yourself with the differing controls for the valve
your appliance uses.
To light millivolt appliances refer to the detailed
lighting instructions found in both English and
French on pages 10 and 11 of these instruc-
tions respectively. millivolt and electronic
appliance lighting instructions may also be
found on the pull out labels attached to the gas
control valve located within the gas control
compartment. Refer to Figure 2 to locate the
appropriate location for the spark ignitor used
with your appliance.
If your 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 the
appliance is not equipped with a wall or remote
control, the main burner must be turned off and
on with the gas control knob. Turn the knob
counter-clockwise from the PILOT position to
ON to light the main burner, and clockwise from
ON to PILOT to turn off the main burner.
