Combustion air supply

Under no circumstances may the combustion air be taken from areas
occupied by people. The combustion air intake opening must not point
in the direction of travel. It must be located so that it cannot become
clogged with dirt or snow and cannot suck in splashing water.
Permissible dimensions of the combustion air intake line Thermo E 200:
– Inside diameter: 55 mm
– Max. permissible line length: 1.5 m without exhaust extension
– Total length of combustion air intake line and exhaust gas line:
max. 2.10 m
– Max. permissible bends: 270°
Permissible dimensions of the combustion air intake line Thermo E 320:
– Inside diameter: 55 mm
– Max. permissible line length: 5 m without exhaust extension
– Total length of combustion air intake line and exhaust gas line:
max. 5 m
– Max. permissible bends: summarized 270°
Deviations must be approved by Spheros.
NOTE:
If the combustion air intake line cannot be installed so that it slopes
downwards, a water drain hole with a diameter of 4 mm is to be made at
its lowest point.
If the heater is installed in a general installation space near the vehicle's
fuel tank, the combustion air must be taken in from the outside and the
exhaust fumes discharged into the atmosphere. The openings must be
made splash-proof.
An effective ventilation opening is required if the heater is installed in an
enclosed box:
2
Thermo E 200 30 cm
2
Thermo E 320 40 cm
Verify by checking the CO values whether the ventilation is effective
2
and sufficient.
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.
