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)
Heat input (per dryer) --- 150,000 Btu/Hr (37,800 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.)
(15-30 mbar) 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 (26.2 mbar). There is no regulator
or regulation provided in an L.P. dryer. The pressure
must be
regulated at the source (L.P. tank) or an
external regulator
must be
added to each dryer.
