36 American Dryer Corp. 112144-46
NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.
Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each dryer
to assure that the water column (W.C.) pressure is correct and consistent.
NOTE: Water column pressure requirements (measured at the gas valve pressure tap):
Natural Gas ............................ 3.5 Inches (8.7 mb) Water Column.
Liquid Propane (L.P.) Gas ..... 10.5 Inches (26.1 mb) Water Column.
IMPORTANT: There is no regulator provided in an L.P. dryer. The water column pressure must be
regulated at the source (L.P. tank) or an external regulator must be added to each
dryer.
b. Electric Models
Check to insure that the heating units (electric ovens) are functioning properly.
c. Steam Models
Check to insure that the steam dampers open and close properly. If steam dampers open and/or close too
fast, make the necessary adjustments at the steam damper/piston flow control valve. Refer to the illustration
on page 33.
4. Make a complete operational check of ALL safety related circuits (i.e., lint basket switches and sail switches).
5. Each basket (tumbler) should be operated through one (1) complete cycle to assure that no further adjustments
are necessary and that ALL components are functioning properly.
NOTE: The sail switch (gas and electric models only) can be checked for proper operation by opening
the control door while the dryer is running and the heating unit (burner) is active (on). The
heating unit(s) should shut off within a few seconds. If not, make the necessary adjustments.
BASKET (TUMBLER) COATING
The basket (tumbler) is treated with a protective coating. We suggest dampening old garments or cloth material with
a solution of water and nonflammable mild detergent and tumbling them in the basket (tumbler) to remove this
coating.
NOTE: Drying and cooling cycles are complete when the light emitting diode (L.E.D.) display reads
“donE.”
