2. Technical Data
a. Gas Specifications
Shaded areas are stated in metric equivalents
* Measured at the gas valve pressure tap when the gas valve is on.
b. Gas Connections:
Inlet connection ______1-1/2” F.P.T.
Inlet supply size ______1-1/2” Pipe Diameter (minimum)
Btu/hr input _________395,000 (99,538 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 (14.92 mb) and a maximum of 12.0 inches (29.9 mb) water
column (W.C.) pressure.
2) Liquid Propane (L.P.) Gas
The 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.
Shaded area is stated in metric equivalent
* Drill Measurement Size (D.M.S.) equivalents are as follows:
Natural Gas ............................. #3 = 0.2130” (5.4102 mm).
Liquid Propane Gas ................. #30 = 0.1285” (3.2639 mm).
