CAUTION :
The hot air release pipes must not be in contact with
the different parts of the smoke evacuation circuit and
must not pass through the smoke pipe.
•
Start from the appliance with pipes of the longest
height possible to favour the flow by convection,
limit horizontal pipes and bends.
•
Make sure there is a 'back' circuit of air coming
from the rooms to be heated to the rooms where
the appliance is set (if there isn't put one in place).
Pay attention that the working of the hot-air circuit
doesn't disrupt the ventilation device of the house.
•
It is important to make sure that during the working
of the appliance the 'convection' air output enters
the inlet port and goes out from all the outlet ports.
If it is not the case, reduce the section of the
working port until the other ports blow hot air : the
use of adjusting ports allows to make this balance
easy.
•
The shutter plate mounted before the outlet port at
the front can be adjusted in order to vary the outlet
of the hot air port, yet it keeps a 'safety' air path of
10 mm : it avoids the overheating of the appliance
when none of the four ports (Ø 125) are open.
NOTA : Once the fireplace is finished, the superficial
temperature of the walls of the house against which the
fireplace is put must not exceed 50° C on accessible
parts (Fig. 13).

Recommendations
examples
The appliance must be set up on a floor with a sufficient
bearing capacity. If the existing construction does not
comply
with
this
prior
measures must be taken to allow the floor to bear the
appliance, such as setting up a load distribution plate.
5.7.1 - Installation within a New Fireplace to be Built
•
Fig 17 shows installation within a DEVILLE
fireplace.
•
The connection method shown is the most
common one :
-
Connection to a masonry flue connected to the
ceiling by a special fixing device.
Other possibilities exist : see DTU 24-2-2.
-
•
A hot air outlet with a minimum section of 800 cm
should be installed at the front or sides, at least
300 mm from the ceiling, to expel the heat and
reduce the inside temperature of the structure.
•
A hot-air release vent can also be installed in the
room behing the fireplace or upstairs on the room
above see paragraph hot-air distribution.
5.7.2 - Installation in an existing fireplace built with
refractory materials and initially made to be
an open hearth
and
installation
requirement,
appropriate
Connection with the chimney (see example Fig.
14) :
• It is necessary to smoke-tight obstruct the base
of the smoke flue
hamper the good running of the appliance.
• Make a seal
steel collar
- Block with refractory mortar the collar
- The upper part of the mortar crown
funnel-shaped.
• Place the linking pipe
that is kept in high position.
- The end of the pipe mustn't go beyond the
collar
appliance.
-The linking pipe will have a diametre al least
equal to 180 mm.
Connection with the appliance:
•
Place the appliance in the hearth (see
paragraph 5.8) and fit the pipe on the original
nozzle of the appliance (Fig. 14).
- If the space is big enough, insert the pipe in the
noozle placing the hands between between the
upper part of the appliance et the base of the collar
.
- If there is not space enough above the appliance to
place there the hands, the insertion of the pipe can
be done easily in putting first in this piece of pipe at
about ten centimetres from its base a broach
which will allow to seize the the pipe to insert it on
the noozle passing the hand from the inside of the
appliance. This broach can stay there without
hampering the working of the appliance (Fig. 15).
NOTA : The connecting pipe
have to be made of stainless steel with a minimum
thickness of 0,4 mm .
•
The sketches 18 and 19, given as example,
represent 2 cases of common installations:
- Fig. 18 : Existing pipe, lined.
Possibility of hot air release through the head and
the existing hood.
- Fig. 19 : existing pipe, kept as it is.
. The design, condition or sizes of the chimney do
not allow to a hot air release through the chimney
head. The hot air goes out fully under the pediment
and the beam.

. A wooden beam has then to be completely
protected in that case.
. The masonry collar has to be built the lowest
possible.
. The built-in fitting measures of the Fig. 12 have to
be respected.
