CARBON MONOXIDE POISONING

This heater is a direct burning type heater that burns the kerosene/light oil then heat. This product is primarily
intended for temporary heating of well ventilated buildings under construction, alteration, or repair. Direct
heating type means that every substance burned at heater enter into the inside of the heating space directly.
Some carbon monoxide is generated from this product whose combustion rate is 98%. Ordinary person can
endure a little bit of carbon monoxide however, preventative measures should be taken with proper ventilation.
Improper ventilation not in compliance with this manual could lead to death. Use this heater only in well ventilated
areas. Early signs of carbon monoxide poisoning resemble flu-like symptoms such as headaches, dizziness, and/
or nausea. Some people are more affected by carbon monoxide than others. These include pregnant women,
those with heart or lung problems, anemia, or those under the influence of alcohol, or at high altitudes. Never use
this heater in living or sleeping areas.
Comply with the following without fail:
• Check the unit for shipping damage. If the unit is damaged, promptly inform dealer where you purchased
heater. Do not use a damaged unit.
• Do not alter this product. Do not use this product if it has been altered.
• Use only kerosene or light oil fuel. In the case of light oil, movement may not be smooth in a specific
environment.
• Do not use fuel such as gasoline, benzene, alcohol, white gas, camp stove fuel, paint thinners, or other
explosive fuels in this heater (THESE ARE VOLATILE FUELS THAT CAN CAUSE A FIRE OR EXPLOSION).
• Primarily for use outdoors, if used indoors insure adequate ventilation.
• Open space of min. 1m² per 23,000Kcal is required. Refer to the ventilation section of this manual.
• Do not use at a residential street.
• Do not use in a place where the product is exposed to water, rain, or sprayed liquid.
• Do not use where flammables such as gasoline, paint thinner, or volatile vapors/liquids are stored.
• Keep all combustible materials away from this heater.

MINIMUM CLEARANCES

Front/Ceiling: 5ft, Sides/Rear: 3.12ft
• Use only on a stable and level surface.
• Do not block air inlet (rear) or air outlet (front) of heater. Do not use duct work in front or at rear of this unit.
• Keep out of reach of children and animals.
• Do not move or handle heater while still hot.
• Do not transport heater with fuel in its tank.
COOLING AND VENTILATING PROCESS
This unit needs plenty of air (oxygen) to burn the fuel in the combustion chamber. To achieve a good combustion,
proper ventilation is necessary. If there is to much air from the ventilation system a blue flame will be generated
and ignition could fail. If there is poor ventilation a yellow flame will be generated. Poor ventilation will cause a
lot of smoking and smell. To prevent overheating if the air gets to hot while in use a cooling fan will be activated
along with a ventilating fan.
ELECTRIC CIRCUIT PROTECTION
This heater's electrical system is protected by a fuse mounted to the PCB Assembly that protects it and other
electrical components from damage. If your heater fails to operate, check this fuse first and replace as needed.
Refer to specification chart.
FLAME DETECTOR
This unit utilizes a photocell to monitor the flame in the burn chamber during normal operation. Should the burner
flame extinguish, it will cause the heater to shut off.
OVERHEATING PROTECTION SENSOR
This unit is equipped with a heat sensor designed to detect overheating during normal operation. If the
temperature of the heater goes over 176 °F to 194 °F the sensor will activate and cause the combustion chamber
to stop.
SETTING TEMPERATURE CONTROL FUNCTION
Use the temperature control knob to set the desired temperature. The unit will activate when the room
temperature is lower than the temperature shown in the display window.
