b. Gas Connections:
Inlet connection -------------------------------------- 1-1/4” F.P.T.
Inlet supply size -------------------------------------- 1-1/4” F.P.T. (minimum)
Btu/hr input (natural gas)--------------------------- 395,000 (99,540 kcal/hr)
Btu/hr input (liquid propane [L.P.] gas) ---------- 345,000 (86,940 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
water column (W.C.) - 29.9 mb - pressure.
2) 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 (26.1 mb). There is no regulator
or regulation provided in a 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.
