2. Technical Gas Data
a. Gas Specifications
* Measured at gas valve pressure tap when gas valve is on.
W.C. = Water column in inches.
b. Natural Gas
Regulation is controlled by each 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 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 (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.
