SECTION B:
SAFETY TIPS FOR OPERATION
3

The FF 55 is designed for use with Paraffin. Use of low-quality fuel will cause burner performance to drop, leading
to abnormal combustion and reduced heater life.
Purchase only Paraffin, in non-red cans reserved exclusively for fuel and marked accordingly with the word
“PARAFFIN”. Always store your fuel in a separate area from where you store gasoline for your power equipment to
avoid accidental use of gasoline in your heater.
What to Buy . . .
ALWAYS: Clean and high-quality Paraffin.
ALWAYS: Fuel free of contaminants, water or cloudiness.
NEVER: Gasoline, alcohol, white gas, camp stove fuel or additives.
NEVER: Yellow or sour-smelling fuel.
How to Store It . . .
ALWAYS: Store in a clean container, clearly marked PARAFFIN.
ALWAYS:
Store away from direct sunlight, heat sources or extreme temperature
changes.
NEVER: In a glass container, or one that has been used for other fuels.
NEVER: For longer than six months. Begin each heating season with
fresh fuel; discard at the end of season.
NEVER: In the living space.
Why It is Important . . .
Pure, clean fuel is essential for safe and efficient heater operation. Poor quality or
contaminated fuel can cause:
●Excess tar deposits on burner and flue pipe
●Incomplete combustion
●Reduced heater life
Use of a highly volatile flammable fuel such as gasoline can produce uncontrolla-
ble flames, creating a severe fire hazard.

SECTION G:
TROUBLESHOOTING
17

At the close of each heating season, or when you do not plan to use your heater for an extended period, the
following procedures are recommended.
1. As the end of the season approaches, calculate your fuel purchases so that you can use up all the fuel you
have on hand. When fuel is stored for over six months, its quality may deteriorate. The use of such fuel will
have an unfavorable effect on heater operation.
2. If your heater needs any service or repair, now is the time to call your dealer and get it done before storage.
That way your heater will be ready for immediate use when the next heating season begins.
3. If you plan to store your heater in place,
(a) Disconnect power supply.
(b) Close the main tank valve.
(c) Remove all fuel from the fuel sump and clean the fuel strainer.
(See Page 16.)
(d) Wipe off any stains or dust on heater with a damp cloth, then wipe once
again using a dry cloth.
(e) Cover heater completely with a large plastic bag to protect from dust.
4. To store heater in another location,
(a) Disconnect heater.
(b) Close the main tank valve.
(c) Remove all fuel from the fuel sump and clean the fuel strainer.
(d) Disconnect fuel line and flue pipe from the heater.
NOTE: Fuel remaining in the fuel line may flow out when fuel line is disconnected. Have a container ready
to catch drainage.
(e) Remove any soot accumulated in the flue pipe using a brush and/or vacuum cleaner.
(f) Wipe off any stains or dust on heater with a damp cloth, then wipe once again using a dry cloth.
(g) Put the heater in the original shipping box, and store in a dry place. If original shipping box is not
available, cover the heater completely with a large plastic bag to protect from dust during storage.
(h) Cover exhaust and air intake openings of the flue pipe by using optional caps.

GENERAL DESCRIPTION: The FF 55 is designed to be installed in an outside wall so the full advantage of installa-
tion simplicity can be made with the “Flue Pipe”, which eliminates the need for tall chimney type flues. No hearth or
fire surround is required. While some Flue pipe wall extentions are available, they complicate installation. Read and
understand the limitations of Flue pipe wall extension options. (See Page 20.)
