IMPORTANT: Failure to comply with these codes or ordinances and/or the requirements stipulated
in this manual can result in personal injury or component failure.
The gas dryer installation must meet the American National Standard, National Fuel Gas Code ANSI Z223.1-
LATEST EDITION, or in Canada, the Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST
EDITION (for Electrical Connections) as well as, local codes and ordinances, and must be done by a qualified
technician.
NOTE: Undersized gas piping will result in ignition problems and slow drying and can create a safety
hazard.
The dryer must be connected to the type of gas (natural or L.P. [liquid propane]) indicated on the dryer data
label. If this information
DOES NOT agree with the type of gas available, contact the distributor who sold
the dryer or contact the factory.
The gas input ratings shown on the dryer data label are for elevations up to 2,000 feet (610 meters), unless
elevation requirements of over 2,000 feet (610 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 (610 meters) are made by
changing the burner orifices. If this adjustment is necessary, contact the distributor who sold the dryer or contact
the factory.
NOTE: Any burner changes must be made by a qualified technician.
