2. Technical Gas Data
a. Gas Specifications
* Measured at gas valve pressure tap when the gas valve is on.
b. Gas Connections:
Inlet connection ----- 1-inch N.P.T.
Inlet supply size ----- 1-inch N.P.T. (minimum)
Btu/hr input (per dryer) ----- 343,000
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 inches and a maximum of 12 inches water column
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 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.
*D.M.S. (Drill Material Size) equivalents are as follows:
