NOTE: Manometers are available from the factory by ordering ADC Part No. 122804.

1.To test gas water column (W.C.) pressure.

a.Connect water column test gauge connection to gas valve pressure tap (1/8” N.P.T). This pressure tap is located on the outlet (downstream) side of the valve.

b.Start the dryer. With burner on, the correct water column reading in inches would be:

Natural Gas __________________ 3.5 Inches (8.7 mb) Water Column Liquid Propane (L.P.) Gas _______ 10.5 Inches (26.1 mb) Water Column

2.To adjust water column pressure for natural gas models, remove vent cap. Turn the slotted adjustment screw located on top of the valve next to the terminals. Turn clockwise to increase manifold pressure and counterclockwise to decrease. For L.P. gas models there is no regulator on valve.

NOTE: If correct water column pressure cannot be achieved, problem may be due to an undersized gas supply line, a faulty or underrated gas meter, etc.
