HIGH ELEVATION
This unit is approved for altitude 0 to 1372m.
GAS LINE
INSTALLATION
Since some municipalities have additional local
codes it is always best to consult with your local
authorities.
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.
NOTE: A shutoff / dante valve should be
supplied in or near the unit (or as per local
codes) for ease of servicing this appliance.

PILOT ADJUSTMENT
1.13 kpa
Periodically check the pilot fl ames. Correct fl ame
0.4kpa
pattern has two strong blue fl ames: 1 fl owing
around the fl ame sensor and 1 fl owing across
0.87 kpa
the burner (it does not have to be touching the
burner).

Note: If you have an incorrect fl ame pattern,
contact your Regency
instructions.
Incorrect fl ame pattern will have small, probably
yellow fl ames, not coming into proper contact
with the rear burner or fl ame sensor.
GAS PIPE PRESSURE
2.75 kpa
The appliance must be isolated from the gas sup-
1.6 kpa
ply piping system by closing its individual manual
shut-off valve during any pressure testing of the
2.49 kpa
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.
23 Mj
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked
28 Mj
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 unit 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) Turn the unit on with the remote or wall switch
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 unit, 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.

adjusting due to either the local gas supply or
altitude. Open the air shutter for a blue fl ame or
close for a more yellow fl ame.

from improperly setting the aeration
controls is NOT covered under warranty.
