TROUBLESHOOTING THE
TUMBLER
1. Exhaust airflow restriction. Exhaust duct size is
recommended to be larger than the exhaust opening.
2. Tumbler inlet air is essential for each unit. Inlet air
must be five to seven times the combined areas of the
tumbler exhaust outlet.
3. All tumbler panels must be in place and on the
machine for proper operation.
4. Gas Models Only: Burner flame improperly
adjusted. Adjust the burner air sleeve.
5. Gas Models Only: Gas pressure must be 6 to 8 inches
water column (1.49 to 1.74 kPa) for natural gas and
11 inches water column (2.74 kPa) for propane
(bottled gas).
6. Gas Models Only: Make sure that the correct size of
gas pipe is being used for the length of the gas circuit.
7. Gas Models Only: Burner orifices must be the
correct size. Natural and L.P. gas do not use the same
orifices.
8. The input voltage must be the same as that indicated
on the serial plate.
9. The back draft damper must swing full open to
prevent airflow restrictions. (Less than full swing
operation of the exhaust damper can cause the
airflow switches to shut off gas, creating a longer
drying time.)
