2.4. Chimney built around the hearth
Follow the installation instructions provided by the
chimney manufacturer.
-
Avoid jamming the appliance in the hearth.
-
Check proprer operation of the moving parts (flap,
valve, door, etc...) to ensure they are not blocked by
installation materials (plaster, cement, etc...).
Remark
: The base of the fireplace must be completely
level to avoid hampering the opening of the appliance’s
glazed door.Once the appliance has been placed on
the base, check that the door opens without chafing.
-
If it chafes, raise the appliance and, if necessary, turn
the door adjustment screw.
2.5. Insertion inside an existing chimney
Make sure hearth dimensions are sufficient
(height : 571 mm, width : 703 mm and depth : 464 mm).

1
- Possible tubing with venthole in case existing
pipe is not compatible.
2
- Decompression holes to ventilate the
space between deflector and ceiling.
3
- Deflector to guide convection air.
4
- Flue in chimney, flue tile or insulated metallic
pipe.
5
- Warm air diffusion grate (minimum 500 cm3).
6
- Insulation (rockwool)
7
- Protection hood for girder.
8
- Frieze under girder, brick or fireproof concrete.
9
- Convection air-inlet
Convection circuit :
-
Ensure that the convection air can enter freely
under and all around equipment, circulate around
the firebox (on the sides and behind) and escape
through diffusion vents in the hood (minimum
500 cm
2
).Good circulation of convection air allows
for optimum heat exchange with the cast walls of
the firebox without any local overheating as well as
a good ventilation of the hood.
10
- Base (or stake), with correct levelling,
ventilated, on a solid and reinforced ground.
11
-
Inspection hatch (500 x 350 mm)
to allow
access to connection pipe, draught regulator,
pressure points, etc...
D
- Safety distance :
minimum of 16 cm from the interior wall of the pipe
(do not insulate the non-combustible part around
the pipe across the ceiling.
