2. Technical Gas Data
a. Gas Specifications
Shaded areas are stated in metric equivalents
* Measured at outlet side of gas valve pressure tap when gas valve is on.
b. Gas Connections
Run a 1-1/2” pipe from the main gas header to the dryer. There is a 1-1/4” gas pipe connection at the top
of the dryer. The dryer has a gas burner box with a 1-1/4” gas connection.
Inlet connection ------------ 1-1/4” N.P.T.
Inlet Supply Size ----------- 1-1/2” N.P.T. (minimum)
Btu/hr input (per dryer) --- 650,000 (163,800 kcal/hr)
1) Natural Gas
Pressure regulation is controlled by the gas valve’s internal pressure regulator. Incoming supply
pressure
must be consistently between a minimum of 6.0 inches (14.92 mb) water column and a
maximum of 12.0 inches (29.9 mb) water column.
2) Liquid Propane Gas
Pressure regulation is controlled by the gas valve’s internal pressure regulator, which is blocked
open so that the gas pressure
must be
regulated upstream of the dryer. The pressure measured at
the gas valve pressure tap
must be
a consistent 10.5 inches (26.1 mb) water column. There is no
regulator or regulation provided in a liquid propane gas dryer. The water column
must be
regulated
at the source (liquid propane tank) or external regulator/regulation must be added to each dryer.
Shaded area is stated in metric equivalent
* Drill Measurement Size (D.M.S.) equivalents are as follows:
Natural Gas ........................ #1 = 0.2280” (5.7912 mm).
Liquid Propane Gas ............ #29 = 0.1360” (3.4544 mm).
