Liquid Propane (LP)
Liquid Draw
The dryers have internal vaporizers and are designed to operate on liquid draw from the supply tank.
The tank should be 1000 gallons or larger and should not have a regulator mounted to it. The connection
to the dryer should be with a flexible hose designed for LP gas,
for proper size.
Consult your LP gas dealer for proper fittings, connection hose and safety controls required to meet local
standards and to conform with National Fire Protection Association standards. The piping train on the
dryer includes strainer, pressure relief valve, electronic safety shut off valve (on some models) and a
pressure regulator between the vaporizer and burner.
Ammonia Tanks
Do not use tanks which have previously been used for ammonia or fertilizer solutions. These substances
are extremely corrosive and will damage fuel supply and burner parts.
Oil or Water in Tanks
With liquid draw from the supply tank, any water or oil present in the tank may freeze in the pipe train or
controls causing damage. To make sure the tank is free of moisture, it can be purged with methanol.
Avoid tanks which may contain an accumulation of oil or heavy hydrocarbon from long use on a vapor
withdrawal system.
