2. Technical Gas Data
a. Gas Specifications
b. Gas Connections
Inlet connection ------------1/2" inch N.P.T.
Inlet supply size ------------1/2" inch N.P.T. (minimum)
Btu/hr input (per dryer) --- 130,000 (32,760 kcal/hr)
1) 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 and a maximum of 12.0 inches water column (W.C.)
pressure.
2) 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 water column (W.C.). There is no regulator or
regulation provided in an L.P. dryer. The water column (W.C.) pressure must be regulated at the
source (L.P. tank) or an external regulator must be added to each dryer.
