American Dryer ML-200 manual Type of GAS

2.Technical Gas Data a. Gas Specifications

		TYPE OF GAS
	Natural		Liquid Propane
Manifold Pressure*	3.5 inches W.C.	8.7 mb	10.5 inches W.C.	26.1 mb
Inline Pressure	6.0 - 12.0 inches W.C.	14.92 - 29.9 mb	10.5 inches W.C.	26.1 mb

Shaded areas are stated in metric equivalents

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

b.Gas Connections:

Inlet connection ---- 1-1/4 inch N.P.T. Inlet Supply Size ---- 1-1/2 inch N.P.T.

Btu/hr input --------- 750,000 (189,000 kcal/hr)

1)Natural Gas

Regulation is controlled by the dryers gas valve internal regulator. Incoming supply pressure must be consistently between a minimum of 6.0 (14.92 mb) and a maximum of 12.0 inches water column (29.9 mb) pressure.

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 blocked open so that the gas pressure must be regulated upstream of the dryer. The pressure is measured at each gas valve pressure tap 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.
