a) Connect the water column test gauge (manometer) to the gas valve pressure tap (1/8" N.P.T.). Refer
to the illustration above.
b) Start the dryer... with the burner on, the correct water column pressure (W.C.) reading in inches
should be:
Natural Gas .......................... 3.5 - 4 inches W.C.
L.P. (liquid propane) Gas ....... 10.5 - 11 inches W.C.
When a gas dryer in first started (during initial time of installation or start-up), it has a tendency not to
ignite on the first ignition attempt. This is due to the fact that the gas supply piping is filled with air,
so it may take a few minutes for the air to be purged from the supply lines. During this purge period
there may be insufficient gas pressure for ignition, which might cause the DSI module to go into the
"LOCK-OUT" mode (the L.E.D. [light emitting diode] will LIGHT "RED" CONTINUOUSLY).
NOTE: "HEATER FAULT" will occur during the initial set-up of the dryer, indicating that the burners
are not lighting due to air in the gas line.
To reset the dryer when a "HEATER FAULT" occurs, press the ("amber") "HEATER FAULT"
reset push-button.
c) If gas pressure is low, unscrew slotted regulator cover on top of the gas valve and turn regulator
(pressure) adjustment screw (located underneath the cover) clockwise (CW) to increase the pressure.
a. System Diagnosis
1) Gas Pressure
A gas pressure test should be taken at the gas valve pressure
tap provided on every gas valve to assure that the water column
(W.C.) pressure is correct and consistent.
There are two (2) types of devices commonly used to measure
water column (W.C.) pressure. They are the spring and
mechanical type gauge and the water column test gauge
(manometers). The use of the spring and mechanical type
gauges IS NOT RECOMMENDED because they are not
always accurate. The preferred type of gauge is the
manometer because it is a simple device to use and is highly
accurate. A manometer is simply a glass or transparent plastic
tube with a scale graduated in inches. When it is filled with
water and pressure is applied, the water in the inner tube lowers,
showing the exact water column (in W.C.) pressure in inches.
WARNING: Test ALL connections for leaks by brushing on a
soapy water solution. NEVER TEST FOR
LEAKS WITH A FLAME!!!
