If an optional blower is installed, Do Not turn

A white film may develop on the glass front
during the first few fires as part of the curing

the first two weeks of use to prevent the film from
baking on (making it very difficult to remove).

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. Familiarize
yourself with the gas control valve that your
appliance uses. Refer to Figure 1 for access
to the gas control valve.
Millivolt appliances - Appliances with
Millivolt systems will be fitted with the gas
control valve shown in Figure 3.
electronic appliances - Appliances with
electronic systems will be fitted with the
electronic valve shown in Figure 4.
Millivolt appliances - To light millivolt appli-
ances refer to Figure 2. Detailed lighting instruc-
tions are found on pages 18 and 19 . Millivolt
appliance lighting instructions may also be
found on the pull out lighting instruction labels
attached to the gas control valve.
Once the pilot is lit, the main burner may be
turned ON and OFF using wall switch, remote
control, optional on unit rocker switch (FRS),
or wall thermostat. To operate: Toggle the
switch between its ON and OFF positions.
If your millivolt appliance is equipped with an
optional remote switch kit (wall switch, remote
control, rocker switch, or wall thermostat) and
the pilot is lit, the appliance main burner may be
turned on and off using the optional switch.
