Liquid Propane (LP)
Top Dry dryers have internal vapor-
izers, and they are designed to oper-
ate on liquid draw from the supply
tank. Avoid using propane supply
tanks that have been used for vapor
draw for long periods of time. When
using liquid draw systems any mois-
ture that may be present in tanks or
lines may freeze when the system is
used in cold weather. To avoid this
situation, purge the system with
methanol. Do not use tanks which
have previously been used for am-
monia or fertilizer solutions. These
substances are extremely corrosive
and will damage fuel supply and
burner parts. Because the vaporizer
coil may need to be adjusted during
operation flexible hose suitable for
LPs should be used for the final field
connection.
See the “Fuel Systems and Rec-
LP line field connection.
