Connecting the exhaust venting
system to the Combi furnace
1. Slide the hose clamp (Fig. 15 – 4) onto the
combustion-air supply tube (Fig. 15 – 2).
2. Slide the hose clamp (Fig. 15 – 4) with the
claws facing the furnace over the exhaust
tube (Fig. 15 – 1).
3. Slide the exhaust tube (Fig. 15 – 1) into the
connection (Fig. 15 – 11) until it fits snugly.
4. Slide the exhaust tube clamp (Fig. 15 – 3)
onto the connection until it fits snugly. The

Circulated air intake
The furnace draws in circulated air from inside
the vehicle.
Risk of carbon-monoxide poisoning!
If exhaust enters the RV, carbon monoxide
in the exhaust can poison people and cause
death.
• The opening for the circulated air intake
must be installed in a position so that no
exhaust from the vehicle's engine or from
the furnace can be drawn into the RV.
• Constructional measures must prevent
contamination of the circulated air.
• There must be an opening for the circulated
air intake between the RV's interior and the
installation space. This opening must be at
least 23.25 in.² (150 cm²).
– Several small openings are permissible if
their collective surface area amounts to at
least 23.25 in.² (150 cm²).
– If a grid is installed (Fig. 16 – 1), the same
size requirement regarding cross-sectional
area (23.25 in.² (150 cm²)) for drawing in air
must be observed.
