MILLIVOLT OPERATING INSTRUCTIONS
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 will energize 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 to two minutes before you turn
the gas control knob from the PILOT position to the ON position.
This time period allows the millivolts 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 the control compartment behind the door assembly.
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.
NOTICE: 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 76.
Rotate the knob clockwise to
and counterclockwise to
"LO"
3.
Turn the REMOTE/OFF/ON switch to
valve to
"OFF"
when the operating season is over. The
system, including the pilot light, will shut down.
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
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 fireplace will not require such purging
if the gas valve is not turned to
Pilot Flame
The thermopile/thermocouple (standing pilot) tips should be
covered with flame.
Electric (120 volt) Operated Remote Control, FREC (Optional)
Connect the green and red, stripped and bare, wires on the
REMOTE/OFF/ON switch wire harness to the wires on remote
receiver that is a component in the FREC. Turn the REMOTE/
OFF/ON switch to the REMOTE position. Follow instructions in
the FREC to complete installation.
NOTICE: If the electric (120 volt) fails to the FREC, and
immediate heat is desired, turn the REMOTE/OFF/ON switch
from the REMOTE position to the ON position.
Installation of Remote Receiver
Place remote receiver on the floor of fireplace behind the lower
louver assembly or barrier assembly as far forward as possible.

Attention: The Velcro loop and hook are not necessary in this

installation but can be used to secure remote receiver.
Refer to remote control installation and operating instructions for
more details on remote control.
Millivolt Control
The valve regulator controls the burner pressure which should
be checked at the pressure test point. Turn captured screw
counter clockwise 2 or 3 turns and then place tubing to pressure
gauge over test point (Use test point
After taking pressure reading, be sure and turn captured screw
clockwise firmly to re-seal. Do not over torque. Check for gas
leaks.
Millivolt thermopile is self-generating. Gas valve does not require
24 volts or 110 volts.
