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 op- eration (optional equipment). In lieu of remote or remote wall switch operation, 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 con- trol 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.

Figure 1

Millivolt appliances will be fitted with one of the two gas control valves shown in Figure 2 on page 4. Appliances with electronic sys- tems will be fitted with the electronic valve shown in Figure 3 on page 4. Familiarize yourself with the differing controls for the valve your appliance uses.

To light millivolt appliances refer to the de- tailed lighting instructions found in both En- glish and French on pages 10 and 11 of these instructions respectively. Millivolt and elec- tronic appliance lighting instructions may also be found on the pull out rating plate located within the gas control compartment. Refer to Figure 2 for the spark ignitor location 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.

To light electronic appliances refer to the detailed lighting instructions found in both English and French on pages 12 and 13 of these instructions respectively. Millivolt and electronic appliance lighting instructions may also be found on the pull out rating plate located within the gas control compartment.

If your appliance is equipped with an optional remote wall switch or remote control kit the appliance main burner may be turner on and off with the wall switch or remote control. If the 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 from ON to OFF.
