Inis Mor MK2 Boiler stove

The installation must allow good air
circulation around the stove to maximise
heat transfer to the room and to avoid
the fireplace overheating. To achieve
this, at least an air gap of 300mm above
the stove and 150mm either side should
suffice.
Please note that in an installation with
a wooded mantelpiece or wood beam, a
greater air gap of up to 650mm, or the
use of appropriate shielding should be
fitted. Building regulations should also
be checked in this regard.
Chimney
This stove is not suitable for a shared
flue arrangement.
Chimneys must satisfy standard EN
15287:2007 and Building Regulations Ap-
proved document J.
A draft test should always be performed
prior to the fitting of the stove to en-
sure that a proper draught in the chim-
ney is present (25PA Constant). A chim-
ney height of at least 4m from the top
of the stove must be used. The chimney
diameter must be at least 153mm. The
chimney must be in good condition, be
cleaned and free from cracks and block-
ages.
The chimney must not have too great a
cross sectional area and if it is (Max
200mm Diameter), the chimney should be
lined with a suitable flue liner for
solid fuel. All chimneys and or flues
used must be sealed for the best possi-
ble performance.
If a chimney is not present, then a pre-
fabricated block chimney or twin walled
flue can be installed.
The draught in the chimney must be at
least 20 Pa when warn and must not suf-
fer from down draughts and if there is
an excessive draw in the chimney a
draught stabiliser should be fitted. If
a draught stabiliser is installed please
ensure more air ventilation is provided
into the room. If any doubt exists
please contact a chimney expert.
In some cases although quite rare a
chimney will not produce a sufficient
and stable draught and the fitting of
the stove to this chimney will not pro-
duce satisfactory clean and proper out-
put. It is very important to examine al-
ternatives before connecting the stove
in this case.
Connection to flues
Building Regulations Approved Part J
must be adhered to installing a fabri-
cated flue system for the stove. When
installing the stove to the chimney care
should be taken to assure that the chim-
ney can be swept and soot removed
properly and easily. If the stove is to
be connected using the top flue outlet
the chimney can be swept through the
stove.
Horizontal sections of flue should be
avoided or at least kept to a minimum.
Horizontal flue sections from the stove
or on any part of the flue pipe should
be 7” MAXIMUM in the horizontal. If the
flue needs to carry in any particular
direction greater than 7”, the flue
should rise at 45 degrees to the hori-
zontal so as to prevent the degradation
