Clothes Dryer User Manual

a) Connect water column (W.C.) test gauge (manometer) to the gas valve pressure tap (1/8”

N.P.T.).

b) Start the dryer...with the burner on, the correct water column reading in inches should be:

Natural Gas .................................. 3.5 inches (8.7 mb) water column.

Liquid Propane (L.P.) Gas ............ 10.5 inches (27.4 mb) water column.

When a gas dryer is 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 Direct

Spark Ignition (DSI) module to go into the LOCKOUT mode (the light emitting diode [L.E.D.]

will BLINK “GREEN” CONTINUOUSLY).

NOTE: During the purge period, check to be sure that ALL gas shutoff valves are open.

NOTE: To reset the DSI module if it is in the LOCKOUT mode, open and close the main door then

restart the dryer.

2) Ignitor/Flame-Probe Assembly Adjustments

The ignitor/flame-probe assembly consists of a ceramic insulated ignitor electrode, a ground rod, and

a ceramic insulated flame-probe electrode. The gap between the ignitor electrode and the ground

rod is set, and must be maintained at 1/8” +/- 1/32” (3.175 mm +/- 0.79248 mm). When the DSI

module provides the high voltage (HV) synchronous spark (14,000 volts) through the high voltage

(HV) lead, a spark is produced over the gap. When this spark is produced, the gas valve is opened.

Upon ignition, the resistance in the flame-probe electrode (of the ignitor/flame-probe assembly)

changes. Once the resistance is changed, it initializes the DSI to sustain the gas flow (from the gas

valve).

IMPORTANT: The gap setting on the ignitor/flame-probe assembly is critical.

a) DSI Ignitor/Flame-Probe Assembly

Adjustments (TUBE BURNER TYPE)

(1) The gap on the ignitor/flame-probe assembly must

be set, and held at 1/8” +/- 1/32” (3.175 mm +/-

0.79248 mm). If this 1/8” gap is not maintained

(if the gap is either too large or too small), the

DSI module will indicate a system malfunction

and go into the LOCKOUT mode (L.E.D. will

BLINK “GREEN CONTINUOUSLY).
