b.Gas Connections

Run a 2” (5.08 cm) gas pipe from the main gas header to the dryer. There is a 2” (5.08 cm) gas pipe connection at the bottom of the dryer base.

Inlet Connection ----------- one (1) 2-inch F.P.T.

Btu/hr input (per dryer) --- 1,600,000 btu/hr - 403,200 kcal/hr

1)Natural Gas

Pressure regulation is controlled by both gas valve’s internal regulators. Incoming supply pressure must be consistently between a minimum of 6.0 inches water column (W.C.) - 14.92 mb - and a maximum of 10.5 inches water column (W.C.) - 26.1 mb.

2)Liquid Propane (L.P.) Gas

Dryers made for use with liquid propane (L.P.) gas have both of their gas valve’s internal pressure regulators open so that the gas pressure must be regulated upstream of the dryer. The pressure is measured at each gas valve pressure tap and must be a consistent 10.5 inches water column (W.C.) - 26.1 mb. There is no regulator or regulation provided in an L.P. gas dryer. The water column must be regulated at the source (L.P. tank) or external regulator/regulation must be added to each dryer.
