G. GAS INFORMATION
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 with 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.
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 shut-off 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 shut-off 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 dryer from 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, 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 label affixed behind the right
control box door. 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.
