2. Installation instructions
2.1. Warning to the user
All the local and national regulations, and in
particular those relating to national and European
standards, must be observed when installing the
appliance.
The heat released by an Insert fire is definitely higher
than that of an open chimney.
An incorrectly installed Insert 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
a c c o r d i n g t o t h e Sta n d a r d s a n d t h e B u i l d i n g
Regulations for safety reasons. The installation must be
carried out according to the Standards and the Building
Regulations.
T h e a p p l i a n c e s h o u l d o n l y b e i n s t a l l e d b y a
professional engineer, in the strict application of normal
practices and all safety precautions.
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.
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.
Site of the chimney : For new installations, select a
central position within the house, to provide a good heat
distribution around the building. The diffusion of the hot
air to the other rooms will be done through the doors or,
in the case of rooms located at another floor, through
grilles in the hood. 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.
Floor : Make sure that the floor can support the weight
of the appliance its surroundings and the hood ; In the
contrary the floor needs to be reinforced with a concrete
screed to distribute this load. Provide adequate
insulation if the floor is combustible. In all cases it is
better to raise the height of the appliance to protect the
floor of the heat radiation and allow fresh air required for
the convection bellow the closed hearth.
Rear wall and ceiling : Make sure they are not
combustible or covered with combustible material (as
per the Building regulations). In the contrary take out
these materials on the all perimeter of the chimney and
replace them by a non-combustible material (as per the
Building Regulations but if in doubt, consult your Dealer
or local Building Inspector). In all cases the surface
temperature on the external side of the walls (walls,
ceiling, floor) shall not exceed 50 °C in all accessible
parts.

2.3. Flue
T h e f l u e m u s t c o m p l y w i t h C u r r e n t B u i l d i n g
Regulations. If in doubt, consult your Dealer or local
Building Inspector.
Existing flue :
- The flue must be in good condition and must provide
sufficient draught (to see page 3).
- The flue must be suitable for the installation of fuel
burning appliances ; otherwise it must be necessary to
install a tubing.
- The flue must be clean. It should be swept to remove
soot and dislodge tar deposits.
- The flue must be well insulated. If the flue inner wall
surfaces are cold, a good thermal draught is impossible
causing condensation problems (tar formation, etc...) to
occur.
- The flue must be watertight.
- The chimney must have a constant cross section.
(Example : 4 dm² for an open fire and 2,5 dm² for a
closed hearth).
- When the cross-section of the chimney is too large, it
is difficult to obtain a good draught.
- The flue must not be shared with any other appliance.
- The chimney must be at least 4.5 m (15 ft) high and be
at 40 cm above the ridge of the roof and 8 meters away
from any construction (fig. 3).
- In case of a flat roof or when the roof gradient is lower
than 15°, the stack must be 1,2 m (4 feet) high at least
(fig. 3).
- The capping must not restrain the draught.
- If the chimney has a down-draught tendency, due to its
p o s i t i o n i n r e l a t i o n t o n e a r b y o b s t a c l e s , a n
anti-down-draught cowl must be installed on the
chimney or the chimney height must be increased.
- If the chimney draught is excessive or irregular, a
draught stabilizer (barometric damper) must be
installed to the connector pipe it must be visible and
accessible.
