Gas Fireplace 29
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 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 speci ed on the safety
label.
6) When nished reading manometer, turn off the
gas valve, disconnect the hose and tighten the
screw (clockwise) with a 1/8" at screwdriver.
Note: Screw should be snug, but do not
over tighten.
HIGH ELEVATION
This unit is approved for altitude 0 to 4500 ft.
(CAN1 2.17-M91).
GAS LINE
INSTALLATION
Since some municipalities have additional
local codes it is always best to consult with
your local authorities and the CAN/CGA B149
installation code.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or ex connectors use only
approved ttings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and ex
connectors are usually considered to meet this
requirement.
NOTE: A shutoff / dante valve should be sup-
plied in or near the unit (or as per local codes)
for ease of servicing this appliance.
IMPORTANT: Always check for gas leaks
with a soap and water solution or gas leak
detector. Do not use open ame for leak
testing.
Periodically check the pilot ames. Correct
ame pattern has three strong blue ames:
1 owing around the thermopile, 1 around
the thermocouple and 1 owing across the
burner (it does not have to be touching the
burner).
Note: If you have an incorrect ame pattern,
contact your Regency
®
dealer for
further instructions.
Incorrect ame pattern will have small,
probably yellow ames, not coming into
proper contact with the rear burner or
thermopile or thermocouple.
