2. Technical Gas Data

a. Gas Specifications

b. Gas Connections:

Inlet connection ------------ 3/4-inch N.P.T.
Inlet supply size ------------ 3/4-inch N.P.T. (minimum)
Btu/hr input (per dryer) --- 200,000 (50,400 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.
