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 flame 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.
