Aeration Adjustment; Gas Pipe Pressure Testing; Sit Valve Description - HAMPTON BAY H27U-NG Owners & Installation Manual

Aeration Adjustment

The burner aeration is factory set but may need ad-
justing due to either the local gas supply, air supply
or altitude.
Natural Gas 3/16" (4.76 mm)

Gas Pipe Pressure Testing

The appliance must be isolated from the gas sup-
ply 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 flat
screwdriver.
3) Attach manometer to "IN" and/or "OUT" pres-
sure tap(s) using a 5/16" ID hose.
4) Light the pilot and turn the valve to "ON" posi-
tion. 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
