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.

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 the 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, unless elevation
requirements of over 2,000 feet 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 are made by changing each
burner orifice. If this conversion is necessary, contact the distributor who sold the dryer or contact the ADC
factory.
