If fuel is taken by the fuel line to the engine, the fuel line from the fuel tank to the fuel filter should be
disconnected and reconnected with the thicker T reducer pipes. The thinner T reducer pipe should connect
the heater fuel pump with the fuel line fitting and the pipe. The installation angle must be according to the
figure below: otherwise, the normal operation of the heater will be disturbed.
After installation, start the vehicle engine, and then turn it off after a minute of operation to remove air
trapped in the fuel suction line.

Installation of the combustion air intake pipe and the gas discharge pipe
The combustion air must be drawn in as fresh air from the outside of the vehicle. The exhaust gases from the
combustion process must be discharged into the air through the exhaust pipe. Measures must be taken to
prevent exhaust gases from entering the vehicle again.
The cables pass through the outer wall or openings at the bottom of the vehicle. Measures must be taken to
prevent the ingress of water splashes. The cables must be secured and permanently shockproof.
Only the air inlet hose and the exhaust hose supplied with the heater may be used. The air intake pipe is a
corrugated pipe made of aluminium pipe, the surface of which is covered with plastic and paper. The exhaust
pipe is a corrugated stainless steel pipe. You need to identify them and not make a mistake during installation.
To connect them to the heater, use the provided clamps to securely attach them to the combustion air inlet
and the exhaust pipe vent, respectively. The protective hood on the air inlet and exhaust outlet openings
must be kept in good condition. It must not be damaged or removed.
