2. Technical Gas Data
a. Gas Specifications
Shaded areas are stated in metric equivalents
* Measured at the outlet side of gas valve pressure tap when gas valve is on.
b. Gas Connections
Inlet connection ------------- 1/2” N.P.T.
Inlet supply size ------------- 1/2” Pipe (minimum)
Btu/hr input (per dryer) ---- 72,000 (18,144 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 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 .............................. #33 = 0.1130” (2.8702 mm).
Liquid Propane Gas ................. #51 = 0.0670” (1.7018 mm).
