Create an air intake (minimum air passage cross-section 300
cm³) if one does not exist and place it under the lower part
of the fireplace. If the fresh air intake opens directly to the
outside, it must be placed facing the dominant winds. If there
is a protection grid, ensure that passage is compatible with
the fireplace requirements. Check that the air intakes are not
blocked on a regular basis.
Danger: no fresh air intake, or one which is not adapted to
requirements may lead to combustion gases being released
into the room, causing the occupants to experience
drowsiness, nausea or faintness.
To the fireplace
The primary air intake grid located on the front of the fireplace
must not be blocked. See figure 1 page 13 and the product
technical sheet attached to this manual. If the fireplace is
placed on the floor without its adjustable legs, the convection
air intake openings at the base of the stove must be unblocked,
see figure 1 page 13 and the product technical sheet attached
to this manual.
2.4. Required distances and
measurements
Openings to be made in the surround
See figure 1 page 11 and "Convection air intake and outlet" in
the product technical sheet attached to this manual.
Distance between the stove and non-inflammable
backing wall
50mm minimum in addition to the thickness of the insulation,
see drawings figures 1 and 2 on page 11.
Recommended insulation
50mm of rock wool, 90 kg/m3 foliated with aluminium sheet
on one side. See figures 1 and 2 page 11.
Distance from furniture
1,3 mètre MINIMUM
Connection flue chimney diameter
See «Connecting a flue» in the product technical sheet
attached to this manual. It is essential to maintain the smoke
outlet cross-section when connecting the flue.

3.0 Installation

Before beginning installation, ensure that the parts of the
fireplace are operating correctly (see the product technical
sheet attached to this manual) :
- guillotine and side hinged door operation : first remove the
screws blocking the weigths, identified by a fluorescent label;
- damper control operation;
- primary air vent operation.

3.1. Protecting the backing walls

All material of a combustible nature or which may be damaged
by heat must be removed from the surrounding walls (floors,
walls and ceilings) where the fireplace is to be placed, see
figure 1 page 11.
The required insulation must be installed using class A1 or at
least M0 insulating materials, and a 50 mm minimum layer of
ventilated air between the fireplace and the insulation.
In all cases, the installation environment must be in
compliance with current legislation and regulations in the
country of installation

3.2. The floor

The floor must be able to bear the weight of the assembled
fireplace and surround. See the product technical sheet.
Extra support may be required.

3.3 The surround

The fireplace surround must be made of non-combustible
materials (please refer to current standards).
The surround interior must be fully insulated. It is essential to
have a 50 mm minimum layer of ventilated air between the
insulation and the fireplace. See figures 1 and 2 page 11.
The surround must be self supporting and must not be
attached to the appliance. At least 3mm clearance must be left
between the surround and the fireplace to allow the appliance
to dilate.

3.4. Air circulation

Fresh air intake must come out under the base of the fireplace.
Air must be able to circulate between the room where the
fireplace is installed and the foundations via purpose-made
vents.
Air must be free to circulate between the fireplace and the
surround. It is also essential to ensure that the air supply to the
vents in the base and under the fireplace is not blocked, see the
product technical sheet attached to this manual and figure 1
page 11.
Convection air outlets should be connected to the diffusion
grids using purpose-made ducts (Ø 125mm), respecting
evacuation surface area, see the product technical sheet
attached to this manual.
Hot air outlets must be at least 300 mm from the ceiling, see
figure 1 page 13. The ceiling must be made of non-combustible
material.
For the double-sided model, decompression grids must be
installed in each room adjoining the fireplace to optimize a
good and well-balanced pressure. In the same way, hot air
grids must distribute in each adjoining room.
3.5. Connecting to the flue chimney
The fireplace can be connected to a chimney and a flue pipe
approved for solid fuel fireplaces, with the smoke
temperatures specified in the product technical sheet attached
to this manual.
