Burner Flame

Gas Dryers

IMPORTANT: This operation to be conducted by
qualified personnel only.

To view the burner flame, remove the lower front

panel of the dryer.
Close the loading door, start the dryer in a heat setting

(refer to the Operating Instructions supplied with the

dryer); the dryer will start, the igniter will glow red

and the main burner will ignite.

IMPORTANT: If all air is not purged out of gas
line, gas igniter may go off before gas is ignited. If
this happens, after approximately one minute,
igniter will again attempt gas ignition.

IMPORTANT: If igniter is not lit, make sure gas is
turned on.

After the dryer has operated for approximately five

minutes, observe burner flame through lower front

panel. 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 the dryer has operated for approximately three

minutes, exhaust air or exhaust pipe should be warm.
