INSTALLATION

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 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.
