The electrical input connections are made at the electric
oven contactor located inside the assembly at the rear center
upper section of the dryer. The ground connection is made
to a copper lug also provided in this area. To gain access,
remove oven rear service cover.
IMPORTANT: A strain relief must be used where the input
wiring enters the oven assembly.
Gas Information ______________________
It is your responsibility to have all plumbing connections,
materials, and workmanship conform to local and state
regulations or codes of the country of destination. In the
absence of such codes, all plumbing connections,
materials, and workmanship must conform to the applicable
local requirements. In the USA this is National Fuel Gas
Code ANSI Z223.1/NFPA 54, or in Canada, Natural Gas and
Propane Installation Code CSA B149.1.
In Australia, the fuel gas code is AS/NZS5601, local authority,
gas, electricity, and any other relevant statutory regulations.
IMPORTANT: Failure to comply with codes or ordinances,
and/or requirements 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 piping 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 due to failure of isolating
or disconnecting the gas supply as noted.

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 (Propane 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 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 (610 meters), unless elevation
requirements of over 2,000 feet (610 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 (610 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.
