To Replace Main Burner Orifices (See Chart On Following Page)

1.Refer to "TO REPLACE GAS VALVE" and follow steps one (1) through six (6).

2.Unscrew main burner orifices and replace.

NOTE: Use extreme care when removing and replacing orifices. These orifices are made of brass and are easily damaged.

3. Reverse the removal procedure for re-installing.

WARNING: Test ALL connections for leaks by brushing on a soapy water solution. "Never Test For Leaks With A Flame".

To Test and Adjust Gas (Water Column) Pressure

There are two (2) types of devices commonly used to measure water column pressure. They are spring/ mechanical-type gauges and manometers. The spring/mechanical-type gauge is not recommended, because it is easily damaged and not always accurate. A manometer is simply a glass or transparent plastic tube with a scale in inches. When filled with water and pressure applied, the water in the tube rises showing the exact water column pressure.

NOTE: Manometers are available from the factory by ordering ADC P/N: 122804

1. To Test Gas Water Column (W.C.) Pressure:

a. Connect water column test gauge connection to gas valve pressure tap (1/8" NPT). This pressure tap is located on the outlet (manifold) side of the valve.

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

Natural Gas – 3.5 to 4 Inches Water Column

L.P. Gas – 10.5 to 11 Inches 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 counter clockwise to decrease. For L.P. gas models there is no regulator on valve.

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