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" 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" pres-
sure tap(s) using a 5/16" ID hose.
To adjust the aeration: use the allen key to turn
the turning gear which will adjust the air shutter.
Open the air shutter for a blue flame or close it
for a more yellow flame. This adjustment is
performed by a qualified installer. The factory
setting should be sufficient for most installa-
tions.
Clockwise to open,
counter-clockwise to close.
Caution: Carbon will be produced if the
air shutter is closed too much.
Note: Any damage due to carboning re-
sulting from improperly setting
the aeration controls is NOT cov-
ered under warranty.
Note: Aeration Adjustment should only
be performed by an authorized
Hampton Installer at the time of
installation or service.
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
