Flame Detector - Newmac NM80ID Manual

This heater is an indirect, air heating unit. This works by burning kerosene/diesel fuel which in turn delivers heat
through the heat exchanger. This heater is used where burned gas exhaust is vented outside of the heated
work space. Exhaust gas from the ventilation outlet and ventilation pipe can be harmful to humans. Proper
ventilation of this unit is critical to prevent carbon monoxide poisoning. Early symptom of carbon monoxide
poisoning is similar with flue. You may get headache, dizziness, tears, mouth dry or sore throat. If this heater
is used where more than two persons are in presence, this safety measure, operation instruction and risk of
accident should be noted. Especially, pregnant women, cardiac and lung patients, anemia patients, alcoholic
and acrophobia patients should be more careful because they may be exposed to carbon monoxide more
sensitively.
BE SURE TO ABIDE BY FOLLOWING THE INSTRUCTIONS.
• Check carefully if the heater is properly vented to the outside. Check to be sure the vent termination is clear.
• Don't modify this product. This is dangerous and will void your warranty.
• Only use kerosene or diesel. If you use diesel, the product may not work properly in some specific condition.
• Never use highly volatile fuels such as gasoline, naphtha, thinner and alcohol because they can explode.
• Be sure to provide good outdoor ventilation for the ventilation pipe when it is used indoor.
• Be careful not to block ventilation if you use extended stovepipe.
• Please be prepared for the case that it can't be ignited if air supply is not sufficient due to lack of indoor
ventilation.
• Don't use it in residential area.
• Don't use it where product is exposed to water, rain or spray liquid.
• Keep away from the place where flammable material such as gasoline, thinner, volatile steam or liquid exist.
• Minimum distance: Top surface: 9.8ft, Side: 6.5ft, Front:16.5 ft
• Use it in the flat and stable place.
• Do not block input and exhaust side of the heater.
• Do not leave the appliance unattended while in operation.
• Keep away from children and animal.
• Handle the heated heater wearing gloves to avoid burn. Don't handle it when it is working.
• Keep all combustible materials away from this heater.
Minimum Clearances: Front: 9 ft, Ceiling: 5 ft, Side/Rear: 3 ft
HOW TO SUPPLY FUEL
This model pumps fuel with motor -driven rotating fuel pump and push it to nozzle through the pipe with high
pressure (7-12kg/cm2), and then the nozzle sprays fuel in the form of micro-particles into the combustion chamber
mixed with air with the constant spray angle.
INSTANTANEOUS IGNITION PROCESS
If the voltage and current for house use flows in the transformer installed in the heater, igniter transform it into
high voltage(16.5kV) current and makes high voltage discharge spark in the terminal of ignition plug. This spark
oxidizes the fuel particles sprayed in the combustion chamber and ignites. High voltage discharge stops after 20
seconds and combustion continues until fuel spray stops due to the heat in the combustion chamber.
COOLING AND AIR BLOWING PROCESS
This heater requires the proper amount of air for proper combustion. So air from the air blowing fan makes
proper combustion process. If the air from this air blowing fan to the combustion chamber is too high, blue flame
can occur and the ignition may fail. On the contrary, if the air is too low, yellow flame can occur, causing poor
combustion and soot can be generated by imperfect combustion. In addition, if the heat in the combustion
chamber goes up due to the ignition, cooling fan and air blowing fan start operating to protect overheating.
PROTECTION OF ELECTRIC CIRCUIT
This heater is equipped with a fuse to protect it from over voltage. But momentary high voltage or lightening
can't be covered by this fuse. If this product doesn't work totally after supplying power, please first check the
fuse in PCB.

FLAME DETECTOR

This heater is equipped with a photo-electric tube which detects flame to check continues combustion when
burning. So this flame detector senses and makes combustion stop, and send error signal to the dashboard when
flame goes out or is not safe.
