750 Millivolt System
The standing pilot (750 millivolt system) is a continuous
burning pilot. The pilot remains ON even when the main
burner is OFF.
When you ignite the pilot, the thermopile produces millivolts
(electrical current) which energizes the magnet in the gas
valve. After 30 seconds to 1 minute time period you can
release the gas control knob and the pilot will stay ON.
Allow your pilot flame to operate an additional one (1) to two
(2) minutes before you turn the gas control knob from the
PILOT position to the ON position. This time period allows
the millivolts (electrical current) to build-up to a sufficient level
allowing the gas control to operate properly.
1. Follow the SAFETY and LIGHTING INSTRUCTIONS
for standing pilot controls found in this manual and on
labels found in control compartment behind the door
assembly.
CAUTION: During the initial purging and subsequent lightings,
never allow the gas valve control knob to remain depressed
in the "pilot" position without pushing the piezo ignitor button
at least once every second.
2. During the operating season, leave the control valve
knob in the "ON" position. This will allow the pilot flame
to remain lit. Turn the burner flame on or off with the
fireplace REMOTE/OFF/ON switch, wall switch or remote
controls.
NOTE: The gas control valve allows you to increase or
decrease the height of the main burner flame. The control
valve has a pressure regulator with a knob as shown in
Figure 49. Rotate the knob clockwise to "HI" to increase the
flame height and counterclockwise to "LO" to decrease the
flame height.
3. When the operating season is over, turn the REMOTE/
OFF/ON switch to "OFF" and the control valve to "OFF".
The system, including the pilot light, will be shut down.

OPERATING INSTRUCTIONS
The OWNER should carefully read and follow these operating
instructions at all times. Lower the door assembly to view the
gas controls for the fireplace.
Initial Lighting
Upon completing the gas line or turning the gas valve on
after it has been in the "OFF" position, a small amount of
air will be in the lines. When first lighting the fireplace, it will
take a few minutes for the lines to purge themselves of this
air. Once the purging is complete, the fireplace will light and
operate satisfactorily.
Subsequent lightings of the appliance will not require such
purging if the gas valve is not turned to "OFF."
Pilot Flame (Figure 50)
The thermopile/thermocouple (standing pilot) tips should be
covered with flame.
