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 flex connectors use only
approved fittings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and flex
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 flames. Correct flame
0.4kpa
pattern has two strong blue flames: 1 flowing
around the flame sensor and 1 flowing across
0.87 kpa
the burner (it does not have to be touching the
burner).

22.7 Mj
32 mj
Note: If you have an incorrect flame pattern,
contact your Regency
instructions.
Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact
with the rear burner or flame sensor.
GAS PIPE PRESSURE
TESTING
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
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.
22.1 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 flat 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 specified on the safety label.
6) When finished reading manometer, turn off
the unit, disconnect the hose and tighten the
screw (clockwise) with a 1/8" flat 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 flame or
close for a more yellow flame.
