2. Technical Gas Data

a. Gas Specifications

* Measured at the gas valve pressure tap when the gas valve is on.

b. Gas Connections

Inlet connection -------- 3/4” N.P.T.
Inlet supply size -------- 3/4” N.P.T. (minimum)
Btu/hr input -------------- 204,000 (51,408 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.

* Drill Material Size (D.M.S.) equivalents are as follows:
Natural Gas .................. #23 = 0.1540” (3.9116 mm).
L.P. Gas ........................ #42 = 0.0935” (2.3749 mm).
