MILLIVOLT SYSTEM OPERATING INSTRUCTIONS
Millivolt System
The standing pilot burns continuously 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 you can release the gas control knob and the pilot will stay
ON. Allow the pilot flame to burn an additional one to two minutes
before you turn the gas control knob from the PILOT position to
the ON position. This allows the millivolts current to build-up to a
sufficient level to operate the gas control 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.
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 59. Rotate the knob
clockwise to "HI" to increase the flame height and counterclockwise
to "LO" to decrease the flame height.
3. When the heating season ends, turn the REMOTE/OFF/ON
switch to "OFF" and the control valve to "OFF". The system,
including the pilot light, will be shut down.

CAUTION
Figure 59
The OWNER should carefully read and follow these operating
instructions.
Initial Lighting
Lower the door assembly to view the gas controls for the fireplace.
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 this air. Once the purging is complete, the fireplace
will light and operate satisfactorily.
Subsequent lightings of the appliance will not require purging if the
gas valve is not turned to "OFF."
Pilot Flame
The pilot flame should cover the thermopile and thermocouple.
