Flue Pipe Connection; Akaba Standard; Akaba Direct Vent Stove; Combustion Air Connection (Akaba Direct Vent Stove ) - HASE Akaba Mode D'emploi

If these specifi cations cannot be met, we advise you to check the suitability of the
chimney by means of a chimney calculation.

Flue Pipe Connection

5.1 Akaba Standard

The Akaba has to be connected to the chimney with a fl ue pipe having an inside diameter
of 120 mm - 150 mm. Please ensure a tight fi t of all pipe pieces at the connection junctions.
The pipe must be well sealed in the chimney entrance and cannot project into the inner
cavity of the chimney; otherwise the fl ue venting will be impaired.

5.2 Akaba direct vent stove

The Akaba direct vent stove has to be connected to the chimney with a fl ue pipe having
an inside diameter of 120 mm - 150 mm. The fl ue pipe has to be sealed at the fl ue pipe
connection piece with Hase
Sealing Paste.
The fl ue pipe connection to the chimney has to be gas proof and sealed with a suitable
sealing cord and heat-resistant silicone (see Fig. 7). The fl ue pipe cannot project into the
cross-section of the chimney, as that can impair fl ue venting.
We recommend using a one-piece fl ue pipe. The total length of the connecting
pipe between the stove and the chimney should not exceed 1.50 m.
6. Combustion Air Connection ( Akaba direct vent stove )
The combustion air in the fi re box is solely supplied by a customer-provided supply air pipe
and the Hase Air System pipe connections. The connecting piece for the Hase Air system is
located on the back side of the stove. The sealed pipe connections are either routed directly
to the outside or connected to a suitable air/fl ue gas system (AFS). Another option is to
provide the supply air from a room with its own independent outside air supply (e.g. cellar
or basement) (see Figs. 7 - 9).
For the customer-provided installation of the air inlet, plain pipes (steel pipes in compliance
72
with 24145, drain pipes in accordance with DIN 19534 and EN 1451B) with a minimum
diameter of 100 mm, a maximum of two bends and a permissible total length of 5 meters
should be used. Verifi cation by calculation is required for longer piping and more than two
bends.
The air supply pipe has to be equipped with an inspection opening for inspecting and
cleaning purposes. The entire air supply pipe has to be airtight.
We advise discussing this with your local planning offi cer.
At the air inlet opening, we recommend installing an animal protection screen with
a mesh size of 10 mm.
7. Butterfl y Valve ( Akaba Standard )
The butterfl y valve is an optional control element. It is fi tted in the fl ue pipe and used to
regulate the fl ue gas fl ow, and can thus slow down the burning-off process. When the
handle's position is diagonal to the fl ue pipe, the fl ue gas fl ow rate is turned to minimum.
We strongly recommend the installation of a butterfl y valve to reduce the output pressure.
Please consider the country-specifi c statutory regulations.
