Regency Bellavista™ B36X Gas Fireplace
INSTALLATION
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 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.
Incorrect fl ame pattern will have small,
probably yellow fl ames, not coming into
proper contact with the rear burner or
thermopile or thermocouple.
HIGH ELEVATION
This unit is approved in Canada for altitude to
4500 ft. (CAN/CGA-2.17-M91). For Natural Gas
installations above 4500 ft. follow current CAN/
CGA-B149.1.
S.I.T. VALVE DESCRIPTION
1) Gas on/off knob
2) Manual high/low adjustment
3) Pilot Adjustment
4) Thermocouple Connection - option
5) Outlet Pressure Tap
6) Inlet Pressure Tap
7) Pilot Outlet
8) Main Gas Outlet
9) Alternative TC Connection Point
PILOT ADJUSTMENT
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
pattern, contact your FPI dealer for further
instructions.
