Electric Dryers
Close the loading door and start the dryer in a heat
setting (refer to Operation section). After dryer has
operated for three minutes, the exhaust air or exhaust
pipe should be warm.
Gas Dryers
IMPORTANT: This operation is to be conducted
by qualified personnel only.
To view the burner flame, remove the lower front
panel of the dryer.
Close the loading door and start the dryer in a heat
setting (refer to Operation section). The dryer will
start, the igniter will glow red and the main burner will
ignite.
IMPORTANT: If all air is not purged out of the gas
line, the gas igniter may go off before the gas is
ignited. If this happens, after approximately two
minutes the igniter will again attempt gas ignition.
IMPORTANT: If igniter does not light, make sure
gas is turned on.
After dryer has operated for approximately five
minutes, observe burner flame. Adjust the air shutter
to obtain a soft, uniform blue flame. (A lazy yellow-
tipped flame indicates lack of air. A harsh, roaring,
very blue flame indicates too much air.) Adjust the air
shutter as follows:
1. Loosen the air shutter lockscrew.
2. Turn the air shutter to the left to get a luminous
yellow-tipped flame, then turn it back slowly to
the right to obtain a steady soft blue flame.
3. After the air shutter is adjusted for proper flame,
tighten the air shutter lockscrew securely.
4. Reinstall the lower front panel.
After dryer has operated for approximately three minutes,
the exhaust air or exhaust pipe should be warm.
