Relevant Building Regulations; Installation; Chimney Connection - HASE SENDAI 175 Operating Instructions Manual

2. Installation Conditions and Relevant
Building Regulations
The stove must be installed in accordance with the
instructions and requirements stipulated by the re-
spective national and European standards and local
regulations.
In Germany, the stove must be registered with the
local master chimney sweep for inspection prior to
initial operation.

3. Installation

Check to make sure that the load bearing capacity
of the installation surface is sufficient for the dimen-
sions and weight of the stove. If necessary, using a
floorplate to distribute the load can increase the load
bearing capacity.
If the stove will be operated as a room air depend-
ent stove, please ensure that the room it will be
installed in has a sufficient supply of combustion
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
blocked.
The stove is only intended to be installed free-stand-
ing. Do not place in alcoves or cover the stove.
CAUTION!
Simultaneous operation of the stove with
ventilation systems and/or exhaust hoods
can cause negative pressure to build up
in the room where the stove is installed,
which can lead to problems such as flue
gas escaping from the stove. If the stove
will be operated as a room air dependent
stove, the negative pressure in the room
where the stove is installed is not permit-
ted to exceed 4 Pascal.
When operated as a direct vent stove, the
negative pressure in the room where the
stove is installed is not permitted to ex-
ceed 8 Pascal (the ventilation system de-
signer specifies the air pressure in Pascal
units). We recommend setting the ventila-
tion system to a maximum negative pres-
sure of 4 Pascal.
NOTE!
To avoid negative pressure in the room
where the stove is installed, we recom-
mend either using a window contact
switch to lock exhaust hoods that guide
the air to the outside or ensuring that a
sufficient amount of air can flow into the
room where the stove is located.

4. Chimney Connection

The stove has to be connected to a suitable chim-
ney with a minimum effective chimney height of
4.5 m.
The exhaust/flue gas system temperature class
(chimney and flue gas pipe) must be at least T400
soot fire-resistant.
To determine whether your stove can be connected
to a chimney to which other fireplaces are already
connected, please consult the technical data con-
tained in the operating instructions (Part I) and
the section on "Connection of Multiple Devices in
Direct Vent Operation". The chimney cross section
should correspond to the flue 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 minimum output pressure (chimney draught)
for your stove model is specified in the technical
data contained in the model-specific operating in-
structions (Part I). At output pressures higher than
specified, the stove emissions increase, which puts
a high load on the stove and can lead to damage.
The stove has a maximum permissible output pres-
sure of 20 Pascal. To limit the output pressure, a
butterfly valve (a) (fig. 2) or output pressure limiter
can be used (only possible with room air dependent
operation).
If a soot fire occurs in the chimney, the flue gas path
has to be checked for leaks and to ensure that it is
tightly sealed. If these requirements and values can-
not be complied with or if there are any doubts or
questions concerning the suitability of the chimney,
we recommend conducting a chimney calculation
according to EN 13384-1/2.
