▶
To prevent this risk, follow the instructions
below.
▶ Do not install this extension in the area in which addi-
tional clamps should be attached; or install an additional
wall bracket
(1) so that the system cannot become
loosened and separated by wind load.
▶
Install an additional wall bracket directly above the
shortened extension
(1) .

Caution.
Risk of corrosion due to improper installa-
tion.
If the flue gas pipe is not designed correctly,
the condensate trap does not work. Silencers
and flue header boxes are not sufficiently
protected against corrosion.
▶
To ensure that condensate that is flowing
back is diverted through the condensate
trap, you must not incorporate any dia-
meter reduction in the flue gas pipe.
1. Insert the equipment connection piece with measure-
ment opening
(1) into the product's condensate trap.
2. For inspection purposes, install at least one inspection
element in the flue gas pipe in the installation room of
the product.
3. Install the extensions (3) , inspection elements, and di-
versions (2) starting from the shaft or external wall (4)
and working towards the product.
4. Finally, insert the elbow or the inspection elbow (2) of
the flue gas pipe into the flue gas connection (1) of the
product.
5. If necessary, use a saw to shorten the extensions.
6. Install the fastening clamps. (

2. Create a borehole.
3. Place the 130/160 mm diameter air pipe adapter (3) on
the air supports (2) of the boiler.
4. If required, install an inspection opening (4) .
5. Insert further pipe elements.
6. Before inserting the last pipe, slide the internal collar
onto this pipe.
7. Insert the last pipe (5) into the shaft opening (6) in such
a way that the outer end is flush with the shaft inner wall
.
8. Secure the air pipe using mortar.
9. Leave the mortar to harden.
10. Install the internal collar on the air shaft.
7.7.2 Installing the combustion air line in the
external wall
1. Determine the installation location of the supply of com-
bustion air in the external wall.
–
The air pipe must terminate on the building side
that is closest to the flue gas opening. This prevents
unacceptably high pressure fluctuations due to the
effects of wind.
–
The air intake must be free of snow.

Height of the intake port: 1 m
