Technical Gas Data
a. Gas Specifications
b. Gas Connections:
Inlet connection ---- 1-1/4 inch N.P.T.
Inlet Supply Size ---- 1-1/2 inch N.P.T.
Btu/hr input --------- 750,000 (189,000 kcal/hr)
1) Natural Gas
Regulation is controlled by the dryers gas valve internal regulator. Incoming supply pressure must be
consistently between a minimum of 6.0 (14.92 mb) and a maximum of 12.0 inches water column
(29.9 mb) pressure.
2) Liquid Propane (L.P.) Gas
Dryers made for use with liquid propane (L.P.) gas have both of their gas valve's internal pressure
regulators blocked open so that the gas pressure must be regulated upstream of the dryer. The
pressure is measured at each gas valve pressure tap must be a consistent 10.5 inches water column
(W.C.) - 26.1 mb. There is no regulator or regulation provided in an L.P. gas dryer. The water column
must be regulated at the source (L.P. tank) or external regulator/regulation must be added to each
dryer.
* D.M.S. (Drill Material Size) equivalents are as follows:
Natural Gas........... #1 = .2280" (5.7912 mm)
Liquid Propane ..... #28 = .1405" (3.5687 mm)
