Heat Check . . .
(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.
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 ignitor is not lit, make sure gas is
turned on.
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. If ignition
does not occur after the fourth ignition attempt, the
control will lock out and red light will flash (see
figure at right). If lockout occurs, open loading
door for one minute to reset control. When control
is properly reset, flashing will stop.
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.
To reduce the risk of serious injury or death,
the lower front panel must be in place
during normal operation.
