Installation
NOTICE
Damage to gaskets due to burred edges on the insertion ends of the
pipe parts!
▶ Make sure the insertion ends are free of burrs. If chamfering on site is
required, only do so in accordance with the manufacturer's
documentation.
For the flue gas routing upwards, use only the original accessory with
supporting lugs.
When converting the flue gas routing upwards, the cover panel is
mounted on the rear panel opening from above.
Flue gas routing on multi-boiler systems (cascade; accessory).
These instructions only concern single boiler systems.
▶ Observe separate technical documentation (information on flue gas
routing and documentation on accessories).
The flue system is to be carried out either in accordance with pressure
classification (EN 1443) H1 or pressure classification (EN 1443) P1
with additional mechanical impact stability up to 5000 Pa.

When installing the flue gas connection:
▶ Observe the installation instructions for the flue accessories.
▶ Observe national regulations.
▶ Make sure that the flue pipe cross-section is calculated in
accordance with all current regulations.
▶ Select the shortest possible route for the flue pipe and install it with
a slope towards the floor standing boiler.
▶ Fasten the flue securely at 1 m intervals.
▶ Ensure the connection is mechanically uncompressed, and that no
loads are transferred to the flue gas connection.
▶ During planning and installation of the flue system, create a
layout that optimised flow favours the flue gas flow.
The wind barriers for the combustion air supply and the flue gas routing
must be installed on the same wall of the building.
The boiler must not be connected to any combined flue system with
motorised motor systems (e.g. combined heat and power unit).

The flue gas connection is intended to the rear ex-factory. The flue gas
connection can also be made at the top. The following conversion
measures are necessary for this purpose:
For the flue gas routing upwards, use only the original accessory with
supporting lugs.
When converting the flue gas routing upwards, the cover panel is
mounted on the rear panel opening from above.
▶ Observe all country-specific requirements when installing the flue
system.
▶ Remove the rear panel.
▶ Remove the 90° flue bend mounter in the factory.
▶ Attach the straight pipe connector (accessory) to the connector on
the condensation catch pan and secure to the upper hood with two
screws. And nuts (Fig. 24).
▶ Install the flue mechanically uncompressed.
