Gas Pipe Pressure Testing
The appliance must be isolated from the gas sup-
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.
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 unit is in the "OFF" position.
2. Loosen the "IN" and/or "OUT" pressure tap(s),
turning counterclockwise with a
3mm wide flat screwdriver.
3. Attach manometer to "IN" and/or "OUT" pres-
sure tap(s) using a 8mm 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 3mm flat screwdriver.
Note: Screw should be snug, but do not over
tighten.
Note: If you have an incorrect flame
pattern, contact your Regency
®
dealer for further instructions.
Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact
with the rear burner or flame sensor.

Periodically check the pilot flames. Correct flame
pattern has two strong blue flames: 1 flowing
around the flame sensor and 1 flowing across
the burner (it does not have to be touching the
burner).

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 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 flame for leak testing.
