NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
If your millivolt appliance is equipped with an
optional remote switch kit (wall switch, remote
control or wall thermostat) and the pilot is lit,
the appliance main burner may be turned on
and off using the optional switch. When using
an optional remote switch, turn off the standard
OFF/ON switch.
OPERATION AND CARE OF YOUR
APPLIANCE
The standard controls for appliance operation
are located behind the panel below the appli-
ance front glass enclosure panel (see Figure
1). Optional control switches are also available
(see Page 14 - Remote Wall Switch, Remote
Control or Wall Thermostat).
Note: To prevent excessive resistance in burner
circuit (which can cause burner operation prob-
lems), only one burner control switch should be
wired to valve. Therefore, if an optional control
switch is installed, the standard Off/On switch
and wires should be removed.

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.
If your electronic 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.
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 fi xed low and high settings
while the appliance is in operation.
Adjust the fl ame height as desired after lighting
the appliance by rotating the variable adjustment
control knob (HI/LO) located on the front of the
valve (refer to Figures 4 & 5).

Electronic Appliances -
To light electronic appliances refer to the detailed
lighting instructions found on Pages 19 & 20
of these instructions. Electronic appliance
lighting instructions may also be found on the
pull out lighting instruction labels attached to
the gas control valve.
2. During the fi rst initial burns of these appli-
ances, there will be some odor emitted (see
Burn-In Period on Page 4).
3. Keep the 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, pet hair, etc. It is very important
that the control compartments, burners
and circulating air passageways of the
appliance are kept clean.
4. Always turn off gas to the pilot (millivolt
appliances) and let the appliance cool down
before cleaning. Before re-lighting, refer to
the lighting instructions in this manual. Light-
ing instructions may also be found on the
pull out lighting instruction labels attached
to the gas control valve.
5. Always keep the appliance area clear and
free from combustible materials, gasoline
and other fl ammable liquids.
6. Remember, Millivolt appliances have a continu-
ous burning pilot fl ame. Exercise caution when
using products with combustible vapors.
