agree with the type of gas available, DO NOT operate the dryer. Contact the reseller who sold the dryer
or contact the ADC factory.

elevation requirements over 2,000 feet (609.6 meters) were specified at the time the dryer order was placed
with the factory. The adjustment of the dryers in the field for elevations over 2,000 feet (609.6 meters) are
made by changing each burner orifice. If this conversion is necessary, contact the reseller who sold the
dryer or contact the ADC factory.
