E. GAS REQUIREMENTS
It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the
gas plumbing installation is adequate and conforms to local and state regulations or codes. In the absence of
such codes, ALL plumbing connections, materials, and workmanship must conform to the applicable
requirements of the 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 (Liquid Propane [L.P.]
Gas) or LATEST EDITION.
IMPORTANT: Failure to comply with these codes or ordinances, and/or the requirements
stipulated in this manual, can result in personal injury and improper operation of
the dryer.
The dryer and its individual shutoff valves must be disconnected from the gas supply piping system during any
pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). The dryer must be isolated from
the gas supply piping system by closing its individual manual shutoff valve during any pressure test of the gas
supply system at test pressures equal to or less than 1/2 psig (3.5 kPa).
IMPORTANT: Failure to isolate or disconnect the dryer from gas supply as noted can cause
irreparable damage to the gas valve, which will VOID THE WARRANTY.
WARNING: FIRE OR EXPLOSION COULD RESULT.
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 dryer data label affixed to the left
side of the main electrical cabinet located in the right hand electrical enclosure. If this information does
not agree with the type of gas available, DO NOT operate the dryer. Contact the reseller who sold the
dryer or contact the ADC factory.
IMPORTANT: Any adjustments to the gas train 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) is made by changing the adjustments on the gas train. If adjustments are necessary, contact
the reseller who sold the dryer or contact the ADC factory.
