4. KEROSENE (1-K)
It is EXTREMELY IMPORTANT for the proper operation of this heater that you use the correct grade
of kerosene. The correct grade of kerosene is identified as 1-K kerosene.
1-K Kerosene has been refined to virtually eliminate contaminants such as sulphur, which can cause
a rotten egg odor during operation of the heater. #1 fuel oil may be used if 1-K kerosene is not available.
KEROSENE SHOULD ONLY BE STORED IN A BLUE CONTAINER THAT IS CLEARLY
MARKED “KEROSENE”. NEVER STORE KEROSENE IN A RED CONTAINER.
Red containers are associated with gasoline.
NEVER store kerosene in the living space. Kerosene should be stored in a well ventilated place
outside the living area.
NEVER use any fuel other than 1-K kerosene (#1 fuel oil is an acceptable substitute.)
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 an explosion or
uncontrolled flames.
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.
Figure 7. Wheel and Handle Assembly, RMC-KFA120T/RMC-KFA170T/RMC-KFA210T MODELS ONLY
NOTE: Heater should be inspected before each use, and at least annually by a qualitied service person.

NEVER LEAVE THE HEATER
UNATTENDED WHILE BURNING!
5. OVERVIEW OF HEATERS DESIGN
Fuel System: This heater is equipped with an
electric air pump that forces air through the air line
connected to the fuel intake and then through a
nozzle in the burner head. When the air passes in
front of the fuel intake it causes fuel to rise from the tank and into the burner nozzle. This fuel and air
mixture is then sprayed into the combustion chamber in a fine mist.
“Sure Fire Ignition”: The electronic ignitor sends voltage to a specially designed spark plug.
The spark plug ignites the fuel and air mixture described above.
The Air System: The heavy duty motor turns a fan that forces air into and around the
combustion chamber. Here the air is heated and then forced out the front of the heater.
The Safety System:
A. Temperature Limit Control: This heater is equipped with a Temperature Limit Control designed
to turn off the heater should the internal temperature rise to an
unsafe level. If this device activates and turns your heater off it
may require service.
B. Electrical System Protection: This heaters electrical system is protected by a circuit breaker
mounted to the power switch that protects the PCB assembly and
other electrical components from damage. If your heater fails to
operate check this fuse first and replace as needed.
C. Flame-Out Sensor: Utilizes a photocell to monitor the flame in burn chamber during
normal operation. It will cause the heater to shut-off should the
burner flame extinguish.
Once the temperature falls below the reset temperature you will be able to start your heater.

6. FUELING YOUR HEATER
NEVER FILL THE HEATER FUEL TANK IN THE LIVING SPACE: FILL THE TANK
OUTDOORS.
DO NOT OVERFILL YOUR HEATER AND BE SURE HEATER IS LEVELED.
IMPORTANT NOTICE REGARDING FIRST IGNITION OF HEATER:
The first time you light the heater, it should be done outdoors. This allows the oils, etc. used in
manufacturing the heater to burn off outside.
WARNING!!: NEVER REFILL HEATER FUEL TANK WHEN HEATER IS OPERATING
OR STILL HOT.
7. OPERATION
A.) VENTILATION
RISK OF INDOOR AIR POLLUTION/USE HEATER ONLY IN WELL VENTILATED AREAS.
Provide a fresh air opening of at least three square feet (2,800 sq. cm) for each 100,000 BTU/Hr.
rating. Provide extra fresh air if more heaters are being used.
Example: A RMC-KFA210T heater requires one of the following:
• a two-car garage door raised six inches (15.24 cm)
• a single-car garage door raised nine inches (22.86 cm)
• two, thirty-inch (76.20 cm) windows raised fifteen inches (38.1 cm)
B.) OPERATION
TO START HEATER
1. Fill fuel tank with kerosene or No. 1 fuel oil.
2. Attach fuel cap.
3. Plug power cord of heater into three-prong, grounded extension cord. Extension cord must
be at least six feet long.
Extension Cord Wire Size Requirements
• 6 to 10 feet (1.8 to 3 meters) long, use 18 AWG conductor.
• 11 to 100 feet (3.4 to 30.5 meters) long, use 16 AWG conductor.
• 101 to 200 feet (30.8 to 61 meters) long, use 14 AWG conductor.
4. Turn “THERMOSTAT CONTROL Knob” to desired setting and push power switch
to ON” position, power indicator lamp will light and heater will start. If heater does not start,
the thermostat setting may be too low, turn THERMOSTAT CONTROL Knob” to higher position
to start heater. If heater still does not start, turn power switch to “OFF” and then to “ON” position.
(See Figure9). If heater still does not start, see Troubleshooting Guide on page 13.

NOTICE: The major electrical components of this heater are protected by a safety fuse mounted to
the PCB board. If your heater fails to start, check this fuse first and replace as necessary.
You should also check your power source to insure that proper voltage and frequency are
being supplied to the heater.

NEVER LEAVE THE HEATER
UNATTENDED WHILE BURNING!
Figure 10
TO STOP HEATER
1. Turn switch to “OFF” and unplug power cord.
TO RESTART HEATER
1.Wait 10 seconds after stopping heater.
2. Repeat steps under to start heater.
8. LONG TERM STORAGE OF YOUR HEATER
1. Drain fuel tank through fuel cap opening.
2. Using a small amount of kerosene, swirl and rinse the inside of the tank.
NEVER mix water with the kerosene as it will cause rust inside the tank. Pour the kerosene out
making sure that you remove it all.
IMPORTANT: Do not store kerosene over summer months for use during next heating season.
Using old fuel could damage heater.
- Reinstall fuel cap. Properly dispose of old and dirty fuel.
- Store heater in dry well ventilated area. Make sure storage place is free of dust and corrosive fumes.
- Store the heater in the original box with the original packing material and keep the USER’S
MANUAL with the heater.
