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 regu-
lator 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" posi-

tion.

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) 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 specifi ed on the safety
label.

6) When fi

nished reading manometer, turn

off the gas valve, 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.

INSTALLATION

Incorrect fl ame pattern will have small, prob-
ably yellow fl ames, not coming into proper
contact with the rear burner or thermopile
or thermocouple.

This unit is approved in Canada for altitude
to 4500 ft. (CAN/CGA-2.17-M91). For Natural
Gas installations above 4500 ft. follow current
CAN/CGA-B149.1.

PILOT ADJUSTMENT

Periodically check the pilot fl ames. Correct
fl ame pattern has three strong blue fl ames:
1 fl owing around the thermopile, 1 around
the thermocouple and 1 fl owing across the
burner (it does not have to be touching the
burner).

Note:

If you have an incorrect fl ame pat-

tern, contact your Regency dealer for further
instructions.
