►►► ASSEMBLY

(PIC. 2)
These heaters are equipped with handles, brackets, supports, etc. depending on the model. These parts, which come with the relative nuts and bolts, are in the heater’s packaging.

►►► FUEL

WARNING: THE HEATER ONLY WORKS WITH DIESEL OR KEROSENE.
Only use diesel or kerosene to avoid any fire or explosion hazard. Never use petrol, naphtha, solvents for paints, alcohol or other highly inflammable fuels.
Use non-toxic, anti-freeze additives in case of very low temperatures.
It is recommended to use winter diesel oil below 5°C.
►►►OPERATING PRINCIPLES
The burner pump draws the fuel from the tank and sends it to the pressurised nozzle where it is nebulised and mixed with comburent air in the combustion chamber. A spark triggers combustion while the waste fumes are expelled from the chimney. A series of sensors constantly checks the correct operation of the heater, stopping the cycle in the case of a fault. The fan, located at the rear of the heater, cools the combustion chamber and the flue gas pass, transferring the heat from the latter into the environment.
