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
