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.

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 specifi 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
