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 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 page 11. The ceiling must be made
of non-combustible material.
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.
The chimney cross-section and the flue pipe connection
to the fireplace must be identical to the cross-section
of the fireplace smoke outlet, see the product technical
sheet.
Only one appliance must be connected to the smoke outlet.
The connection between the fireplace and the flue pipe
must be in compliance with the regulations of the country
of installation. Recommended draught conditions are
15 Pa ±2.
Important: the different seals used for connection must be
airtight. A leak can lead to malfunction.
4.0 Instructions for use
This appliance is dedicated to a closed door operation.
The guillotine function must be used intermittently,
for lighting or for adding wood.
4.1. Identification
and use of control elements
Damper control
Located above the door. This control is to be manipulated
using the cool handle (supplied with the fireplace) as it can be
very hot after several hours of operation.
To adjust the draft damper, turn to the left to open and
to the right to close.
The following adjustments can be made:
- open for lighting (approx. 10 minutes) and when reloading
the fireplace;
- more or less open to adjust power according to requirement.
Figure 4.1.1
Primary air intake adjustment
Located between the lower corner and the door.
This control is used to adjust the quantity of air for burning
wood. The slide pulled to the left corresponds to the open
position. When the fire is lit, the slide should be placed
in open position.
Rate of combustion can then be adjusted by opening
or closing the slide to a greater or lesser extent.
Clean combustion is obtained with air control open allowing a
lively blaze.
Control should be closed when the insert is not in use to keep
cold air of the burn chamber.

4.2 Choice of fuel
Always use good quality wood. Good quality fuel will not
damage the fireplace and will give the best result.
Birch, beech or oak logs make good quality firewood.
Good quality firewood must be dry, which means that it
must have a humidity level lower than 20% (minimum
2 years drying).
The wood must be cut between the beginning of autumn
and the end of winter. It must be cut, split and piled in such
a way as to allow good air circulation. Cover the piles of wood
to protect them from the weather. Logs must be stored under
cover in the autumn for winter use.
The quantity of energy obtained from one kilogram
of firewood does not vary much from one variety of wood
to another. However weight can vary considerably from one
variety to another.
E.g. a specific volume of birch will produce less energy (kWh)
than the same volume of oak, which is heavier.
The quantity of energy produced by 1 kg of good quality
firewood is around 3.8 kWh. 1 kg of completely dry firewood
(zero humidity) will produce approximately 5 kWh, whereas
1 kg of firewood with a humidity level of 60% will only
produce 1.5 kWh.
Using damp firewood causes serious problems:
- soot or tar deposits on the glass, in the fireplace
and in the chimney;
- a drop in the amount of heat produced by the fireplace;
Nota : in position closed, the door is blocked.
