only be installed on one side not less than 200 mm from one another, to exclude suction of
exhaust gases into the intake opening.
Failure to observe the above recommendations may, during extreme weather
conditions (strong wind, pressure difference), not only prevent exhaust but also create
additional underpressure in the air intake area. This leads to abnormal burner operation; the
burner gets sooted and the heater is subject to rapid wear.
Rarely, failure to observe this recommendation may lead to suction of flame into the
air blower.

8.4 Installation of the heater fuel system
Observe the following instructions carefully to avoid emergencies.
8.4.1 Installation of the tank and the fuel pump
The fuel tank must be installed onto proper supports in such a way so that fuel leaking
from the tank, its filling hole, and connections would be spilled onto ground.
Do not position the filling hole in the cabin, trunk, or the engine compartment. If the
filling hole is positioned on vehicle side, the installed plug must not protrude beyond outer
dimensions of the vehicle. Fuel that may leak during the tank filling, must not be spilled
onto the exhaust system and electric wiring. Only spillage to the ground is allowed. Good
practice is to install the fuel pump as close to the tank as possible and below the minimal
fuel level in the tank.
To exclude fuel leakage from the tank by gravity in case of failure of fuel pump
sealing, it is recommended to position the tank in such a way so that the maximal fuel level
would be below the lower edge of the heater fuel pipe end.
