Installation

3.1 Akaba Standard

Check to make sure that the load-bearing capacity of the fl oor / installation surface is suf-
fi cient. If necessary, using a fl oor plate to distribute the load can increase the load-bearing
capacity.
In addition, check whether the room in which the Akaba Standard is to be installed is suf-
fi ciently supplied with fresh air. If the windows and doors are tightly sealed, the necessary
supply of fresh air may not be ensured, which can interfere with the draught capability of
the stove and chimney. If additional combustion air inlet openings are required, they are
not permitted to be closed or obstructed.
Simultaneous operation of the stove and the exhaust hood can cause negative pressure to
build up in the room where the stove is installed, which can lead to problems such as fl ue
gas escaping from the stove.
To ensure that air is not drawn out of the room where the stove is installed, we recommend
locking exhaust hoods that guide the air to the outside by means of a window contact
switch.

3.2 Akaba direct vent stove

The door of the Akaba direct vent stove is self-locking. To ensure that the self-locking me-
chanism functions
perfectly, use the spirit level to precisely align the Akaba direct vent stove in a horizontal
position. The stove can be aligned by means of four levelling feet (see Assembly and Main-
tenance Instructions).
Please make sure that there is suffi cient ventilation in the room where the Akaba direct vent
stove will be installed.
For rooms with a cubic volume of more than 50 m³, an hourly air exchange ratio of
1.5 is required. With smaller rooms, the air change rate needs to be higher. The
negative pressure in the room where the stove is installed is not permitted to
exceed the value of 8 Pascal (the ventilation system designer specifi es the air pressure
in Pascal units). We recommend setting the ventilation system to a maximum
negative pressure of 4 Pascal. To ensure that no air is drained from the room, we
recommend operating exhaust hoods in recirculation air mode or using a window
contact switch to lock exhaust hoods that guide air to the outside.

The Chimney

4.1 Akaba Standard
The Akaba Standard has to be connected to a suitable chimney with a minimum effective
chimney height of 4.50 m. It can be connected to a chimney to which other fi replaces are
already connected. The chimney cross section should correspond to the fl ue pipe cross
section. If the effective chimney height is too low and/or the chimney cross section is too
large or too small, the draught capability of your stove can be impaired.
The Akaba Standard stove requires a 12 Pa output pressure (chimney draft). At higher
output pressures, the stove emissions increase, which puts a high load on the stove and
can lead to damage. The Akaba Standard stove has a maximum permissible output pressure
of 35 Pa.
To limit the output pressure, a butterfl y valve or output pressure limiter can be used.
4.2 Akaba direct vent stove
The Akaba direct vent stove needs its own separate chimney.
The draught capability of your stove can be impaired by a chimney cross section that is too
large or too small and/or an effective chimney height of less than 4.50 m. The „effective
chimney height" is the distance between the fl ue gas intake in the chimney and the top
of the
chimney pot. After a soot fi re in the chimney, the impermeability (air-tightness) of the fl ue
gas paths has to be checked.
We recommend connection to a multi-leaf chimney with a cross-section having a
maximum diameter of 160 mm and a minimum „effective chimney height" of 4.5 m.
