2. Technical Gas Data
a. Gas Specifications
For Australia, refer to data plate.
Shaded areas are stated in metric equivalents
* Drill Measurement Size (D.M.S.) equivalents are as follows:
Natural Gas ............... #19 = 0.1660” (4.2164 mm).
#25 = 0.1495” (3.7973 mm).
#26 = 0.1470” (3.7338 mm).
Propane Gas .............. #43 = 0.0890” (2.2606 mm).
Shaded areas are stated in metric equivalents
* Measured at outlet side of gas valve pressure tap when gas valve is on.

1) Natural Gas
Regulation is controlled by the dryer’s gas valve’s internal regulator. Incoming supply pressure
must be consistent between a minimum of 7.0 inches (17.4 mb) and a maximum of 10.5 inches
(26.1 mb) water column (W.C.) pressure.
2) Propane Gas
Dryers made for use with propane 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 11.0-13.0 inches (27.4 - 32.3 mb) water column.
There is no regulator or regulation provided in a propane dryer. The water column pressure must
be regulated at the source (propane tank) or an external regulator must be added to each dryer.
