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 made by a qualified professional to ensure 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
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 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, 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
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 (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.

Inlet supply size | 3/4” Diameter Pipe (min.) |
Btu/hr input (per dryer) | 160,000 (40,320 kcal/hr) |
Natural Gas
Regulation is controlled by the dryer’s gas valve’s internal regulator. Incoming supply pressure must be consistent between a minimum of 6.0 inches (14.92 mb) and a maximum of 12.0 inches (29.9 mb) water column (W.C.) pressure.
Liquid Propane (L.P.) Gas
Dryers made for use with L.P. gas have the gas valve’s internal pressure regulator blocked open so that the gas pressure must be regulated upstream of the dryer. The pressure measured at each gas valve pressure tap must be a consistent 10.5 inches (26.1 mb) water column. There is no regulator or regulation provided in an L.P. dryer. The water column pressure must be regulated at the source (L.P. tank) or an external regulator must be added to each dryer.
