Electric Dryers
Close the loading door and start the dryer in a heat 
setting (refer to the Operating Instructions supplied 
with the dryer). After the dryer has operated for three 
minutes, the exhaust air or exhaust pipe should be 
warm.
Gas Dryers
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 two minutes 
igniter will again attempt gas ignition.
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:
a. Loosen the air shutter lockscrew.
b. 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.
c. After the air shutter is adjusted for proper 
flame, tighten the air shutter lockscrew 
securely.
d. Reinstall the lower front panel.
After the dryer has operated for approximately three 
minutes, exhaust air or exhaust pipe should be warm.
Figure 23 
For personal safety, lower front panel of 
dryer must be in place during normal 
operation.
