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.
