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 speci
fi
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.

ame or close for a yellower
fl
ame. The burner aeration is factory set but
may need adjusting due to either the local gas
supply or altitude.
