The installation aid may have sharp edges and cut
through the line.
3. Use the line (7) to lower the first flue pipe (3) down far
enough until you can insert the next flue pipe (6) .

Distance between the spacers:
≤
2 m
5. Insert the next flue pipe into the sleeve of the first flue
pipe until they reach a stop.
6. Continue inserting a further flue pipe until you can insert
the lowest pipe into the support elbow.

through the shaft opening to do this.
7.1.6 Installing inspection T-pieces and elbows
Conditions : If the flue gas pipe cannot be inspected from the shaft open-
ing:
▶
Install an inspection T-piece at a suitable location.
Conditions : If diversions are required in the shaft:
▶ Install a 15° or 30° elbow.
1. After every diversion, install an inspection T-piece as
close as possible to the diversion.
7.1.7 Installing the shaft extension
Caution.
Risk of material damage caused by flue
gas or dirt particles.
Flue gases or dirt particles that have been
sucked in may damage the product or lead
to malfunctions. If the opening of the flue gas
pipe for the room-sealed product is immedi-
ately next to another flue gas installation, flue
gases or dirt particles may be sucked in.
▶ Lift the other flue gas installation with a
suitable attachment.
Caution.
Risk of material damage due to thermal
expansion.
Thermal expansion of the plastic (PP) flue
pipe may cause the opening of the flue gas
pipe to increase by up to 20 cm.
▶ Ensure that the necessary free space is
available above the opening.
