2. Technical Gas Data
a. Gas Specifications
Manifold Pressure*
In-Line Pressure
Shaded areas are stated in metric equivalents
* Measured at gas valve pressure tap when the gas valve is on.
b. Gas Connections:
Inlet connection --------------- 1/2" N.P.T.
Inlet supply size --------------- 1/2" N.P.T. (minimum)
Btu/hr input (per dryer) ----- 100,000 (25,200 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
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.
