The dryer must be connected to the type of gas (natural or liquid propane [L.P.]) indicated on the dryer
data label. If this information does not agree with the type of gas available, contact the reseller who sold
the dryer or contact the
ADC factory.
The gas input ratings shown on the dryer data label are for elevations up to 2,000 feet (609.6 meters),
unless elevation requirements of over 2,000 feet (609.6 meters) were specified at the time the dryer order
was placed with the factory. The adjustment for dryers in the field for elevations over 2,000 feet (609.6
meters) is made by changing the burner orifices. If this adjustment is necessary, contact the reseller who
sold the dryer or contact the
ADC factory.
NOTE: Any burner changes must be made by a qualified technician.
