Cabinet Pre-Heating (Diesel Units)
WARNING: Always wear gloves when adjusting the damper.
The burner exhaust is equipped with an adjustable Thermal Regulating Gate (A) to help regu-
late 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)
Open the gate, using the gate lever (B), to the full 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 temperature
below 320º F.
2)
Once the material in tank has started melting and is circulating through the plumbing
system, close the gate. This will prevent excessive cabinet temperatures and will divert
the heat around the oil for more efficient heating.
