kPa). Disconnect piping from valve at pres-
sures 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" 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. Read manometer.
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
