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 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.
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 21. 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.

WARNING
Figure 21
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 22)
The thermopile/thermocouple (standing pilot) tips should be covered
with flame.
Figure 22
NOTICE: During initial cold start-ups, it is recommended that the
pilot be operated only for a period of 3 to 5 minutes (burner off)
in order to encourage proper draft in the flue vent. Refer to the
"Tall Vent Height" section on page 13 for additional information on
adjustment of the flue baffle vent door in order ro imporve cold
start-up conditions.
NOTICE: On Propane (LP) gas models, when the burner shuts off, a
small secondary flash may occur as the burner flame is extinguished.
This is a normal occurence with LP gas and does not affect the
performance or safety of the appliance.
