GAS LINE
INSTALLATION
The gas line can be brought through either the
right, the left side or the bottom of the appli-
ance. The gas valve is situated on the bottom
of the unit.
The gas line connection may be made of rigid
pipe, copper pipe or an approved fl ex connec-
tor. (If you are using rigid pipe, ensure that the
valve can be removed for servicing.) Since some
municipalities have additional local codes it is
always best to consult with your local authorities
and AG 601 (Australian Installation Code) NZS
5261(New Zealand Installation Standard).
When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and fl ex
connectors are usually considered to meet this
requirement.

Important: Always check for gas leaks with a
soap and water solution or gas leak detector.
Do not use open fl ame for leak testing.

PILOT ADJUSTMENT

TM , Regen-
Periodically check the pilot fl ames. Correct
fl ame pattern has three strong blue fl ames:
1 fl owing around the thermopile, 1 around
the thermocouple and 1 fl owing across the
burner (it does not have to be touching the
burner).
Note: If you have an incorrect fl ame pat-
#50
tern, contact your Regency
for further instructions.
Incorrect fl ame pattern will have small, prob-
ably yellow fl ames, not coming into proper
contact with the rear burner or thermopile
or thermocouple.

GAS PIPE PRESSURE
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 3.45 kPa.
Disconnect piping from valve at pressures over
3.45 kPa.
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked
at the pressure test point.

TESTING
®
P121/P121LC/P121RC/P131 Zero Clearance Room Sealed Gas Fireplace
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" posi-
tion.
2) Loosen the "IN" and/or "OUT" pressure
tap(s), turning counterclockwise with a
1/8" wide fl at 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 specifi ed on the safety
label.
6) When fi nished reading manometer, turn
off the gas valve, disconnect the hose and
tighten the screw (clockwise) with a 1/8" fl at
screwdriver. Note: Screw should be snug,
but do not over tighten.
