NEVER LEAVE HEATER
UNATTENDED WHILE BURN-
ING OR WHILE CONNECTED
TO A POWER SOURCE
Operation (Continued)
NOTE: Kerosene should only be stored in a blue container that is
clearly mark ed "kerosene". Never store kero sene in a red contain-
er. Red is associ ated with gasoline.
- NEVER store kerosene in the living space. Kerosene should be
stored in a well ventilated area outside the living area.
- NEVER use fuel such as gasoline, benzene, alcohol, white gas,
camp stove fuel, paint thinners, or other oil compounds in this
heater (THESE ARE VOLATILE FUELS THAT CAN CAUSE A
FIRE OR EXPLOSION).
- NEVER store kerosene in direct sunlight or near a source of
heat.
- NEVER use kerosene that has been stored from one season to
the next. Kerosene deteriorates over time. OLD KEROSENE
WILL NOT BURN PROPERLY IN THIS HEATER.
- Use 1-K kerosene in this heater. #1 fuel is a suitable substitute.

THEORY OF OPERATION

Fuel System:
This heater is equipped with an air pump that
operates off of the electric motor. The pump forces air through
the air line connected to the fuel tank, drawing fuel to the nozzle
in the burner head. Air also passes through the nozzle where it
mixes with the fuel and is sprayed into the combustion chamber
in a fine mist.
Quick-Fire Ignition:
A transformer sends high voltage to a two
pronged spark plug. The spark ignites the fuel/air mixture as it is
sprayed into the combustion chamber.
Air System:
A fan is turned by the heavy duty motor, which
forces air around and into the combustion chamber, where it is
super-heated and forced out the front of the chamber.
Temperature Limit Control:
Temperature Limit Control designed to turn the heater off should the
internal temperature rise to an unsafe level. If this device activates
and turns your heater off, it may require service.
Once the temperature falls below the reset temperature, you will
be able to start your heater.
WARNING
Figure 8. Theory of Operation
This heater is equipped with a
Pinnacle Products International, Inc. Kerosene User's Manual
Electrical System Protection:
is protected by a circuit breaker that protects the system compo-
nents from damage. If the heater fails, check the fuse first, and
replace if necessary.
Flame Sensor:
The heater uses a photocell to "see" the flame
in the combustion chamber. Should the flame extinguish, the sen-
sor will stop electrical current and the heater will shut off.
FUELING THE HEATER
NEVER FILL THE FUEL TANK INDOORS.
CAUTION
ALWAYS FILL THE TANK OUTDOORS.
BE SURE THAT THE HEATER IS ON LEVEL GROUND WHEN
FUELING, AND NEVER OVERFILL THE FUEL TANK.
NEVER REFUEL THIS HEATER WHILE IT
WARNING
IS HOT OR OPERATING. FIRE OR
EXPLOSION COULD RESULT.
It is always a good idea to fire the heater outdoors for the first
time. This will allow any oils used in the manufacturing process to
be burned off in a safe environment. This initial burn should last
at least 10 minutes

VENTILATION

Risk of indoor air pollution. Use heater only in well ventilat-
ed areas.
Always provide a fresh air opening in the heated space of at
least three square feet (2,800 sq. cm) for each 100,000 BTU/Hr.
of heater output. Provide a larger opening if more heaters are
being used. As an example, an MH-215T-KFA heater will require:
- a two-car garage door open 6 inches, or
- a single car garage open 9 inches, or
- two thirty two inch wide windows open fifteen inches.
TO START THE HEATER
1. Fill the tank with kerosene until fuel gauge points to "F".
2. Be sure fuel cap is secure.
3. Plug power cord into three prong, grounded extension cord
and plug extension cord into three prong 120V grounded out-
let. The extension cord should be at least six feet long.
- Extension cord wire size requirements are as follows:
- 6 to 10 feet (1.8 to 3 meters), use 18 AWG wire.
- 11 to 100 feet (3.4 to 30.4 meters), use 16 AWG wire.
- 101 to 200 feet (30.8 to 61 meters), use 14 AWG wire.
4. Turn thermostat control knob to desired temperature setting
(75/135/190/215 only). The setting range is from 40 ° F to 110 °
F. Push the Power switch to the "ON" position (See figure 9).
The power indicator lamp and room temperature display
(135/190/215 only) will light and the heater will start.
NOTE: The room temperature display (135/190/215 only) will
indicate the following:
- When temperature is less than 0 ° F, display says "LO".
- When temperature is above 99 ° F, display says "HI".
- Between 0 ° and 99 ° F display shows actual temperature.
