INSTALLATION
GAS PRESSURE CHECK
WIRING SCHEMATIC (Millivolt Units Only)
NOTE:
The appliance and the appliance main gas
valve must be disconnected from the gas supply
system during any pressure testing of that system
at test pressures in excess of 0.5 psig (3.5 kPa).
The appliance must be isolated from the gas
supply piping system by closing it’s equipment
shut-off valve during any pressure testing of the
gas supply piping system at test pressures equal
to or less than 0.5 psig (3.5 kPa).
1. The gas valve controls the gas pressure, which
can be checked at the pressure test point (1/8”
NPT plug) located on the side of the valve.
2. The pressure should be checked with the
heater burner and the control set to high (HI).
3. The pressure is preset and locked to avoid
tampering. If the pressure is not as specified in
“BTU Rating and Pressure Requirements” (pg.
3), contact your dealer.
4. Replace the test plug after measuring gas
pressure. Check for gas leaks.
IMPORTANT:
Do not use the appliance if any
part has been submerged under water.
Immediately call a qualified technician to inspect
the appliance and to replace any part of the
control system and any gas control which has
been under water.

CAUTION:
Label all wire prior to disconnection
when servicing controls. Wiring errors can cause
improper an dangerous operation. Verify proper
operation after service.
WALL SWITCH INSTALLATION
1. To install a wall switch mount a 3” X 2”
electrical box in the wall near the fireplace. Run
the wire from the electrical box to the millivolt
valve.
2. At the valve connect the lead wires to the two
outside terminals labeled “TH”.
3. On the Wall Switch connect a lead wire to
each terminal.
4. Mount the Wall Switch to the electrical box
and install the cover plate.
***If installing a remote control, thermostat, or
timer, attach the leads from the optional item to
the same terminals as the Wall Switch on the
Millivolt Valve.
