1. Gas Supply
The gas dryer installation must meet the American National Standard...National Fuel Gas Code ANSI
Z223.1-LATEST EDITION, or in Canada, the Canadian Installation Codes CAN/CGA-B149.1 M91 (Natural
Gas) or CAN/CGA-B149.2-M91 (L.P. Gas) or LATEST EDITION, as well as local codes and ordinances
and must be done by a qualified professional.
NOTE: Undersized gas piping will result in ignition problems, slow drying, increased use of energy, and
can create a safety hazard.
The dryer must be connected to the type of heat/gas indicated on the data label affixed to the left wall,
behind the upper control door area (refer to the illustration on page 9). If this information does not agree
with the type of gas available, DO NOT OPERATE THE DRYER. Contact the distributor who sold the
dryer or the ADC factory.
IMPORTANT: Any burner changes or conversions must be made by a qualified professional.
The 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 or conversion of 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
distributor who sold the dryer or contact the ADC factory.
