5.3 Flue Connection
When connecting the boiler with the flue, there are two stages
of montage:
- Montage of the flue pipes and air supply for combustion.
- Connection to the flue.
Montage of the flue pipes and air supply for combustion:
- The
STREBEL
Varan
has an exhaust and an air supply
connection on its back side.
- Only use certified, stainless pipes for the flue connection.
The exhaust connection has a diameter of 80 mm. It is prohi-
bited to reduce the diameter in the following flue pipes.
- The flue gas pipe must not be used for multiple applianes at
once.
- Only use a maximum of two 90° angle pipe pieces. The
maximum length of a horizontal pipe distance is 2 metres.
- In case the pipes are near flammable materials or lead through
them, the pipes must be insulated.
Installation
For safety reasons, the circulator pump is connected to
the controller. In case the water temperature reaches
the critical value of 95°C, the fan ceases operation.
The pump continues running constantly and derives the excess
heat to the radiators, until the temperature is in normal range.
The heating system is to be filled slowly, allowing it to be vented
well. During filling of the installation, check if there are leaks in
the system.
- The pipes and connection elements usually show o-rings
made from silicone. If they do not have this kind of seal,
use fireproof sealing agent.
- The flue pipe must be detachable when necessary or have an
revision opening installed.
- In case the flue pipe does nor lead directly into the flue, but
vertically upwards, the installation of a condensate collector
is prescribed.
- The air supply from outside of the building for combustion
must be guaranteed. Use a pipe consisting of black or Inox
steel. The minimum diameter for this pipe is 50 mm.
- If it is not possible to take fresh air from the outdoors, the
intake must be carried out from an adjecent room with contant
fresh air ventilation. This fresh air connection must be
designed in a way that is is impossible to shut off (e.g. when
closing doors or windows)
Note:
The safety valve of the current version is located not
in front of the boiler like in this picture, but on the boiler
backside.
