FUEL (1-K KEROSENE)

For optimal performance of this heater, it is strongly suggested that 1-K kerosene be used. 1-K kerosene has
been refined to virtually eliminate contaminants, such as sulfur, which can cause a rotten egg odor during the
operation of the heater. However, #1 or #2 fuel oil (diesel fuel) may also be used if 1-K kerosene is not avail-
able. Be advised that these fuels do not burn as clean as 1-K kerosene, and care should be taken to provide
more fresh air ventilation to accommodate any added contaminants that may be added to the heated space.
Using diesel fuel can cause excess soot production. DO NOT use any fuel that is not approved above.
KEROSENE SHOULD ONLY BE STORED IN A BLUE CONTAINER THAT IS CLEARLY MARKED
"KEROSENE". NEVER STORE KEROSENE IN A RED CONTAINER, BECAUSE RED
CONTAINERS ARE ASSOCIATED WITH GASOLINE.
• Never store kerosene in a living area. Kerosene should always be stored in a well ventilated area
outside of the living space.
• Never store kerosene in direct sunlight or near any heating source.
• Never use kerosene that has been stored from one season to the next. Kerosene and diesel fuel
break down over time.
Old fuel will not burn properly in this heater. Use of old or contaminated kerosene can lead to exces-
sive soot production.
NEVER LEAVE HEATER UNATTENDED WHILE BURNING OR WHILE CONNECTED TO A POWER
SOURCE.

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.
Electrical System Protection: The heater's electrical system is protected by a circuit breaker that pro-
tects the system components from damage. If the heater fails, check the fuse first, and replace if neces-
sary.
Flame Sensor: The heater uses a photocell to see the flame in the combustion chamber. Should the
flame extinguish, the sensor will stop electrical current and the heater will shut off.
Tipover Sensor: The heater uses a tipover sensor.

FUELING THE HEATER

WARNING: NEVER FILL THE FUEL TANK INDOORS. ALWAYS FILL THE TANK OUTDOORS. BE
SURE THAT THE HEATER IS ON LEVEL GROUND WHEN FUELING, AND NEVER OVERFILL
THE FUEL TANK.
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.
WARNING: NEVER REFUEL THIS HEATER WHILE IT IS HOT OR WARNING OPERATING. FIRE OR
EXPLOSION COULD RESULT.

VENTILATION

Always provide a fresh air opening in the heated space of at least three square feet (2,800 sq. cm) for the
MH-0125-3M1R. Provide a larger opening if more heaters are being used. As an example, a MH-0125-
3M1R (125,000 BTU/hr) heater will require:
12
