2. Installation instructions
2.1. Warning to the user
An incorrectly installed heating appliance can
cause serious accidents
(chimney fires, burning of
plastic insulation materials, in partition walls, etc.).
The insulation of both the appliance and the exhaust
gas pipe has to be reinforced and done according to the
Standards and the Building Regulations for safety
reasons. The installation must be carried out according
to the Standards and the Building Regulations.
Failure to respect the mounting instructions leads to
engage the responsibility of the one doing the
installation.
The manufacturer’s responsibility shall be limited to the
supply of the appliance.
The installation of the appliance and the flue system
m u s t b e i n a c c o r d a n c e w i t h c u r r e n t B u i l d i n g
Regulations. Failure to install the appliance with the
Building Regulations will lead to the appliance warranty
becoming in validated.
2.2. Location of the unit
Ventilation :
For satisfactory appliance operation with
a
natural draught
, check that sufficient air for
combustion is available in the room. In houses
equipped with one VMC (controlled mechanical
ventilation), this one aspire and renew the ambient air;
in this case, the residence is under slight low pressure
and a
non-sealable
external air intake must be
installed in addition to the chimney itself, at least 50 cm²
in section.
Position of the unit :
For new installations, select a
central position within the house, to provide a good heat
distribution around the building. The heat distribution
towards the other rooms will be made through the
communicating doors. These rooms must be at low
pressure or fitted with
non-adjustable air registers,
placed so that they cannot be obstructed
, to
encourage circulation of the hot air.
When using a single wall flue pipe, there
must be a clearance (A) of at least three times its
diameter (B) from any combustible materials. If the
appliance has to be located in an opening, this distance
must be extended to a minimum clearance (A) of
450 mm from the pipe or the stove body to any
combustible materials.
Hearth :
The appliance must stand on a fireproof
hearth.
It is possible to provide a hearth made of non
combusible board/sheet material or tiles at least 12 mm
thick (C).
Constructional hearths should be constructed of solid
non combustible material at least 125 mm thick
(including the thickness of any non combustible floor
under the hearth).
The hearth must protrude at least 300 mm in front of the
stove and 150 mm each side.

Installation instructions
Figure 2 - Clearances
Floor and walls :
make sure there are not combustible or
covered with non combustible material. Otherwise it must
be necessary to install a non
combustible protection.
There must be a clearance of
at least 150 mm at each side
(back and sides) of the
appliance in accordance with
the below recommandations
from a non combustible wall.
This
distance
must
be
extended to a minimum
clearance of 400 mm from any
combustible material.
If any part of the back or sides
of the appliance lies within
150 mm horizontally of the
wall, than the wall should be
of
solid
non-combustible
construction at least 75 mm
thick from level to a level of
300 mm above the top of the
appliance and 1200 mm above the hearth.
Il however, any part or sides of the appliance lies within
50 mm of the wall, then the wall should be of solid
non-combustible construction at least 200 mm thick from
floor level to a level of 300 mm above the top of the
appliance and 1200 mm above the hearth. Where the
hearth itself in at least 150 mm from an adjacent wall.
There is no requirement for protection of the wall. It
should be noted that these thicknesses of solid non-com-
bustible material can be substituted by thinner material if
the same overall level of protection can be achieved.
