PRESSURE TESTING
IMPORTANT
Pressure check taps for manifold (outgoing) and inlet (incoming) pressure have been incorporated into the valve. The pressure
tap marked OUT measures outgoing pressure and the pressure tap marked IN measures incoming pressure. Follow instructions
below for proper testing procedures. Refer to page 17
for proper NAT and LP manifold pressures.
NOTE
The appliance and its appliance main gas valve must be disconnected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psi (3.5 kPa). The appliance must be isolated from the gas supply piping
system by closing its equipment shutoff valve during any pressure testing of the gas supply piping system at test pressures equal
to or less that 1/2 psi (3.5 kPa).

MANIFOLD PRESSURE TEST:
1. Light
pilot.
2.
Loosen manifold (OUT) pressure tap screw (counter-clockwise).
3.
Attach manometer to pressure tap using a 5/16” I.D. hose.
4.
Turn gas control knob to ON.
5.
Press hand held remote ON button and note manometer reading.
6.
Press hand held remote OFF button.
7.
Disconnect manometer hose and tighten screw (clockwise). Screw should be snug, do not over tighten.
8. Attach manometer to manifold pressure tap to verify it is completely sealed. Manometer should read no pressure when burner is turned
on.
INLET PRESSURE TEST:
1.
Loosen inlet (IN) pressure tap screw (counter-clockwise).
2.
Attach manometer using a 5/16” I.D. hose.
3. Light
pilot.
4.
Turn gas control knob to ON (burner should not light). Note manometer reading.
5.
Press hand held remote ON button. Check pressure to ensure it stays near maximum inlet pressure.
6.
Press hand held remote OFF button.
7.
Turn gas control knob to OFF.
8.
Disconnect hose and tighten screw (clockwise). Screw should be snug, do not over tighten.
9.
Relight pilot and turn gas control knob to ON. Reattach manometer to inlet pressure tap to verify it is completely sealed.
Manometer should read no pressure.

CAUTION
A LOW PRESSURE READING CAN CAUSE DELAYED IGNITION.
NOTE
If inlet pressure reading is too high or too low, contact the gas company. Only a qualified gas service technician should adjust
the incoming gas pressure.
