Gas Connections:
Inlet connection ------------ 3/4" inch N.P.T.
Inlet supply size ------------ 3/4" inch N.P.T. (minimum)
Btu/hr input (per dryer) --- 200,000
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 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. 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.
