valve
The gas valve, whether natural gas or LP, includes the appropriate
regulator and jet (orifice).
4.1.4 Burner
The burner mounts next to the gas valve jet (orifice). A burner ring is
used for natural gas dryers to optimize performance.
The gas dryer burner circuit runs through the motor & Hi-limit. The
connection through the motor cuts out the burner if the motor isn’t
running.
Motor is rated 120
VAC, 60 Hz, 1/3 HP
(248.5 W), 5.0 A,
1725 RPM, 40ºC
ambient, class B
insulation. It drives
the fan (in front) and

4.1.5 Gas leak testing (using soapy water)
Whenever gas connections are changed or disturbed, they should be
checked for leaks using a soapy water solution.
1. Reconnect all gas connections and turn on the gas supply to
the dryer, using household gas inlet pressure.
2. Apply soapy water solution with a spray bottle. Spray union
and brass connections completely.
3. Watch connections carefully for about two minutes. If there is a
leak, bubbles will form in the area of the leak. Soapy water will
not stay on connections long, so spray more solution on them
when soapy water isn’t visible.
4. If bubbles form around the union, tighten the connection and
repeat steps 3 and 4 until no bubbles form.
