ANNUAL MAINTENANCE SCHEDULE
1. FUEL FILTER. Remove the fuel filter from fuel line and direct compressed air
through the filter in the opposite direction of fuel flow. Safety glasses should be
worn when using compressed air.
2. FUEL LINES. If the fuel lines are removed during cleaning, be sure all connections
are tight before operating unit. If any dry rotting or cracking in the lines is observed
replace with 1/4" id fuel line or contact DeWALT for service parts.
STORAGE
Store the heater in a dry location free from fumes or dust.
At the end of each heating season, clean the heater as described in the
MAINTENANCE section. Drain and flush the fuel tank with clean fuel. The
manufacturer recommends completely filling the tank with fuel for extended storage
to minimize condensation inside the tank.
It is recommended to only store kerosene in containers that are marked
"KEROSENE".
SERVICING
A hazardous condition may result if a heater is used that has been modified or is not
functioning properly. When the heater is working properly:
* The flame is contained within the heater.
* The flame is essentially blue with perhaps some yellow tipping.
* There is no strong disagreeable odor, eye burning or other physical discomfort.
* There is no smoke or soot internal or external to the heater.
* There are no unplanned or unexplained shut downs of the heater.
The parts lists and exploded view show the heater as it was constructed. Do not
use a heater which is different from that shown. In this regard, use only the hose,
regulator and cylinder connection fitting (called a POL fitting) supplied with the heater.
