3 Installation
Installation and location
The heater is suitable and certified for installation in parts of vehicles used by persons.
Installation in the cab or passenger compartments of coaches or buses with more than 9 seats is not allowed.
When installing in compartments used by persons, the exhaust, combustion air and fuel pipes in these areas must not have any detachable connections and must be routed splash-waterproof in the breakthroughs. For this reason, the heater can be mounted with its foot using the flange seal in the foot to the vehicle floor or to an outer wall of the vehicle.
The electronic control is integrated in the heater which makes wiring during installation much easier.
Please note! 
•When installing the heater, always make sure there is sufficient clearance left for intake of the heater air and for dismantling the glow plug and controller (see page 15 “main dimensions“).
•The regulations and safety instructions to be observed for this chapter are on page 4 – 7.
