G800C-1 Gas Fireplace
Gas Pipe Pressure Testing
The appliance must be isolated from the gas supply
piping system by closing its individual manual shut-
off valve during any pressure testing of the gas
supply piping system at test pressures equal to or
less than 1/2 psig. (3.45 kPa). Disconnect piping
from valve at pressures over 1/2 psig.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked
at the pressure test point.
Note: To properly check gas pressure, both
inlet and manifold pressures should
be checked using the valve pressure
ports on the valve.
1. Make sure the valve is in the "OFF" position.
2. Loosen the "IN" and/or "OUT" pressure tap(s),
turning counterclockwise with a 1/8" wide flat
screwdriver.
3. Attach manometer to "IN" and/or "OUT" pressure
tap(s) using a 5/16" ID hose.
4. Light the pilot and turn the valve to "ON" position.
5. The pressure check should be carried out with
the unit burning and the setting should be within
the limits specified on the safety label.
6. When finished reading manometer, turn off the
gas valve, disconnect the hose and tighten the
screw (clockwise) with a 1/8" flat screwdriver.
Note: Screw should be snug, but do not over
tighten.
Pilot Adjustment
Periodically check the pilot flames. Correct
flame pattern has three strong blue flames: 1
flowing around the thermopile, 1 around the
thermocouple and 1 flowing across the burner
(it does not have to be touching the burner).
Note: If you have an incorrect flame pat-
tern, contact your Regencydealer
for further instructions.
Incorrect flame pattern will have small,
probably yellow flames, not coming into proper
contact with the rear burner or thermopile or
thermocouple.
