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.

b.Gas Connections:

Inlet connection ---------- 1-inch N.P.T.

Inlet supply size ---------- 1-inch N.P.T. (minimum) Btu/hr input (per dryer) - 300,000 (75,600 kcal/hr)

1)Natural Gas

Regulation is controlled by the dryer’s gas valve’s internal regulator. Incoming supply pressure must be consistent between a minimum of 6.0 inches (14.9 mb) and a maximum of 12.0 inches water column (W.C.) - 29.9 mb - pressure.
