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. 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 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) is made by changing each
burner orifice. If this conversion is necessary, contact the
reseller who sold the dryer or contact the ADC factory.
IMPORTANT: This gas dryer is not provided with an
internal gas supply shutoff and an external gas supply
shutoff must be provided.
Grounding
A ground (earth) connection must be provided and installed
in accordance with state and local codes. In the absence of
these codes, grounding must conform to applicable
requirements of the National Electrical Code ANSI/NFPA NO.
70-LATEST EDITION, or in Canada, the installation must
conform to applicable Canada Standards: Canadian Electrical
Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION.
The ground connection may be to a proven earth ground at
the location service panel.
NOTE: A grounding connection (terminal lug) is provided in
the dryer’s electrical service/relay box at the rear.
For added personal safety, when possible, it is suggested
that a separate ground wire (sized per local codes) be
connected from the ground connection of the dryer to a
grounded cold water pipe. Do not ground to a gas or hot
water pipe. The grounded cold water pipe must have metal
to metal connections all the way to electrical ground. If there
are any nonmetallic interruptions, such as a meter, pump,
plastic, rubber, or other insulating connectors, they must be
jumped out with no. 4 copper wire and securely clamped to
bare metal at both ends.
IMPORTANT: For personal safety and proper operation,
the dryer must be grounded. For proper operation of the
microprocessor controller (computer), an earth (zero)
ground is required.
NOTE: Grounding via metallic electrical conduit (pipe) is
not recommended.

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 supply as noted can cause irreparable damage to the
gas valve voiding the warranty.
Fire or explosion could result.
