Assembly of double pipe extension pipe(s) for balcony gallery output
If free output is hindered by a roof overhang, balcony, gallery etc., the air supply pipe
and combustible gas outlet pipe have to be extended up to at least the front of the
overhanging part.
If the air supply cannot be disrupted by obstacles, such as a console or divider wall
and if the output is not on the edge of a building, the air supply pipe does not need to
be extended.
1. Extend the combustion gas outlet pipe, and possibly also the air supply pipe, of
the double pipe feedthrough with a standard combustion gas outlet and air
supply pipe at the correct length in accordance with the stated measurements.
2. Slide the combustion gas outlet and possibly also the air supply pipe into the
output and input pipe of the double pipe feedthrough.
3. Fit the combustion gas outlet pipe and air supply pipe on a slope towards the
unit.
4. Fit the exhaust rosters on both pipes.
