Cabinet Pre-Heating (Propane Units)
WARNING: Always wear gloves when adjusting the damper.
The burner exhaust is equipped with an adjustable Thermal Regulating Gate (A) and a damper
(B) to help regulate the amount of heat diverted to the cabinet for hose, wand and plumbing
preheating. At the end of each day after cleaning out the system, the hose should be coiled
and placed in the cabinet. The wand may remain attached as it will fit in the cabinet.
NOTE: On units equipped with a heated hose, the hose and wand must remain out-
side the cabinet.
COLD START-UP
1)
Close the damper until it covers the exhaust stack. Open the gate by lifting lever (C) to
the full open position. This will force hot air into the cabinet. The temperature gauge
installed in the side of the cabinet will measure actual temperature.
Never
allow
cabinet temperature to exceed 320º F. Open the door partially if necessary. Adjust
gate or close completely to keep the temperature below 320º F.
2)
Once the material in the tank has started melting and is circulating through the plumbing
system, open the damper and close the gate. This will prevent excessive cabinet
temperatures and will divert the heat around the oil for more efficient heating.
