2.3. Air intake

2.3.1 In the room where the fireplace is installed
Danger: ensure that the intake of fresh air for the appliance
operation is adapted to the room in which it is installed.
Create an air intake (see the product "technical sheet") 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.
2.3.2 To the fireplace
The primary air intake (tube Ø80 or grid) on the front of the
equipment must not be blocked, see the "technical sheet" and
figure 1.
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 and the product "technical
sheet" attached to this manual.
2.4. Required distances and
measurements
2.4.1 Openings to be made in the surround
See figure 1 and "Convection air intake and outlet" in the
product "technical sheet" attached to this manual.
2.4.2 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.
Recommended insulation
50 mm of rock wool, 90 kg/m3 foliated with aluminium sheet
on one side. See figures 1 and 2.
Distance from furniture
1300 mm mimimum
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.
Adjust fireplace height using the adjustable legs (optional
accessories) - Mount according to model.

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.
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.
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

3.4.1 Convection air intake
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.
Convection air outlets should be connected to the diffusion
grids using purpose-made ducts (Ø 125 mm), 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. The ceiling must be made of non-combustible material.
These security measures allow prevent overheating inside the
dressing, while ensuring adequate heating capicity in the room.
3.4.2 Combustion air intake
The fireplace must be equipped with an outdoor air intake.
It must allow the replacement of the burnt air by wood
combustion.
This intake can be connected directly to the fireplace (see the
