Requirements

WARNING: Turn off electric power to the unit before

doing any service or maintenance on the heater.

When burning used automotive diesel and truck oils, this heater will re-

quire more frequent service than conventional heating equipment. All used

oils contain a small amount of ash. This ash is similar in texture to that

found in wood burning fireplaces, and varies with the types of oil used.

FAILURE TO REMOVE THIS ASH ON A REGULAR BASIS WILL

VOID THE WARRANTY.

Do not let your oil supply tank run out of fuel. Check the oil level in the

supply tank daily to be certain an adequate supply is available. Running out

of fuel will require you to re-prime the system.

The following are starting points for tailoring a maintenance schedule to fit

the application. When performing the maintenance procedures listed be-

low, note the hours on the hour meter. After one or two cleanings, the main-

tenance schedule may be altered based on the hours of operation. However,

if there is a major change in the type of used oil being burned, maintenance

requirements can be affected. Any time there is a major change in fuel,

return to the schedule listed below and note the hour meter readings to re-

tailor the maintenance schedule.

At the end of the heating season or whenever the heater will be shut

down for a long period, always turn off the power. Clean the heat ex-

changer/combustion chamber and the flue pipe. Before restarting, perform

all maintenance checks.

Weekly:

• Check the vacuum gauge on the filter for an indication that the oil

line filter needs replaced and/or motor pump screen needs cleaning.

The maximum vacuum rise is 10”Hg; the maximum reading is

15”Hg.

• Inspect the combustion chamber and heat exchanger tubes. If

cleaning is needed, follow the instructions on page 28.

Record the hour meter reading for future reference. A Maintenance

Record Chart is provided in the Appendix for this record.

WARNING: Wear protective clothing, including gloves

and a face mask or respirator. Dispose of ash properly.

See the warning statement on cleaning the combustion

chamber.

Monthly:

• Drain water from the bottom of the supply tank until a steady

stream of oil is obtained.

• Clean the backflow/ash sensor switch. Remove any soot from the

sensor. Check the electrical connections.
