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 flat
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 specified on the safety
label.
6. When finished reading manometer, turn
off the gas valve, disconnect the hose and
tighten the screw (clockwise) with a 1/8" flat
screwdriver. Note: Screw should be snug,
but do not over tighten.

Pilot Adjustment
Periodically check the pilot flames. Correct
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.
