8 Combustion air supply
On no account must the combustion air be extracted from areas where
persons are present. The combustion air intake opening must not point
in the direction of travel. It must be so located that the possibility of clog-
ging due to contamination or snow and the drawing in of splash water is
remote.
The combustion air inlet must not be located above the exhaust gas out-
let.
When the heater is installed in the vicinity of the vehicle tank in a com-
mon installation space, combustion air must be drawn in from the out-
side of the vehicle and the exhaust gas be discharged into the atmos-
phere. Lead-through openings must be splash-proof.
If the heater is located in an enclosed installation housing, a ventilation
opening is required:
DBW 160 / 230 / 300 30 cm
2
DBW 350 35 cm
2
If the temperature in the installation housing exceeds the permissible
ambient temperature of the heater (see Technical Data), the ventilation
opening must be enlarged subject to prior consultation with SPHEROS.
