American Dryer Corp. 30 lb. Stacked Models - Manual (Page 16)

The elryer and its individual shut-off valve
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 valves during
any pressure testing of the gas supply
piping 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
valves ... voiding the warranty.
WARNING: FIRE OR EXPLOSION COULD
RESULT.
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, and
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 located on the inside of the middle
access (control) door. If this information
does not agree with the type of gas
available, contact the distributor who sold
the dryer or the 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 of 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 for dryers in the field for
elevations over 2,000 feet are made by
changing each burner orifice. If this
adjustment
is necessary, contact the
distributor who sold the dryer or contact
the factory.
