Technical Gas Data
a. Gas Specifications
b. Natural Gas
Regulation is controlled by each dryer’s gas valve’s internal regulator. Incoming supply pressure must
be consistent between a minimum of 6.0 inches (14.92 millibars) and a maximum of 12.0 inches water
column (W.C.) - 29.9 millibars - pressure.
c. 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 (W.C.) - 26.1 millibars. 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.

Piping Connections
ALL components/materials must conform to National Fuel Gas Code specifications, or in CANADA, the
Canadian Installation Codes (for General Installation and Gas Plumbing).
It is important that the gas pressure regulators meet applicable pressure requirements and that gas meters
be rated for the total amount of ALL the appliance Btu’s being supplied.
