Recommendations And Typical Installations; Installation Within A New Fireplace To Be Built - deville C07836 Notice D'installation Et D'emploi

5.6.2 Building-in and protection to limit overheating of the casing walls to 65 K
To limit overheating of the casing walls, the instructions below should be followed :
Back wall, both sides and top must be insulated.
-
The floor must be protected.
-
- Respect minimum thermal protections.
- Implement the convection air system of the appliance.
Comply with the minimum fitting dimensions to limit overheating of the fireplace walls to 65 K (K = °C above
-
ambient temperature) and protect the appliance (Fig. 7).
. The insulating material must be rigid and able to support high temperatures without getting warped or
damaged (rated MO material), such as rockwool, 30 mm thick, covered with aluminium foil exposed to the
heat from the appliance.
. The global conductivity of the insulating material must be inferior to 1,3 W/m² ° C.
Example : 30 mm rockwool, conductivity inferior to 0,04 W / 3 ° C , or 80 mm insulating brick, conducti vity
inferior to 0,1 W / m° C.
. Air convection around the stove.
Do not obturate the ventilation points : air coming in from the front under the appliance, circulating between the
side and rear double walls.
The floor shield consists in a reflective metal shielding (thick 7/10
NOTE : If the appliance is installed within an existing fireplace made of refractory materials, basically designed for
an open fire, the minimum building-in dimensions should be complied with in order to protect the appliance.
NOTA : On completion of work, the surface temperature of the backing walls should not exceed 50° C in areas
where they are accessible (Fig. 8).

5.7 RECOMMENDATIONS AND TYPICAL INSTALLATIONS

The appliance must be set up on a floor with a sufficient bearing capacity. If the existing construction does not
comply with this prior requirement, appropriate 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

- Figures 26, 27, 28 and 29, given as examples, show installation in a DEVILLE fireplace.
They show different connection methods, which are :
. Fig. 26 : connection into masonry flue already installed in ceiling by means of special component
. Fig. 27 : connection into masonry flue already installed in ceiling by masonry flange
. Fig. 28 : connection into masonry flue from the floor with refractory concrete lining and sand filling
. Fig. 29 : connection into masonry flue from the floor and accessible soot hatch
- A hot air outlet with a minimum cross-section of 400 cm² should be installed at the front or sides, at 300 mm
from the ceiling, to reduce the inside temperature of the structure.
5.7.2 Installation in an existing fireplace built with refractory materials and normally intended for an open
fire
Connection to the fireplace (see example Fig. 10) :
- lt is essential to ensure that the base of the smoke flue
prevent the appliance from working properly.
- Put the required sealant all around the steel flange
. Fix the flange with refractory mortar.
. The top part of the mortar will result in the shape of a funnel.
. The end of the pipe should not extend beyond the flange
. The diameter of the connecting pipe must be at least 180 mm.
e

is completely smoke-tight. Any air coming in will
. In order to do this :
after insertion into the outlet on the appliance.
