5.3. INSTALLATION OF THE COMFORT AIR KIT
Before installing the natural or forced ventilation COMFORT AIR kit,
make sure you have the following material available (fig.1):
1. For natural ventilation: connect the hoses (a) and the
flanges (d) Ø 150 to the connections on the upper part of the
stove unit (fig.1).
For forced ventilation: connect the flanges (d) and the hoses
(a) Ø 100 to the connections on the upper part of the stove
unit. Forced ventilation uses hoses with a smaller diameter than
those used for natural ventilation.
2. prepare on the wall (f) at the desired height two holes for the
hot air outlets measuring 185 mm x 185 mm
3. Insert the structure of the selected outlet (g) in the holes of
185 x 185 mm, working from the outside towards the inside of
the wall
4. on the inner part of the wall, at the structure of the air outlet
(1), attach the fastening bracket group (2), using the four
screws and nuts provided (fig.2)
5. connect the hose (a), previously fastened to the fireplace hose,
to the connection located on the structure of the air outlet (e)
6. tighten the hose (a) on the connection (e) with the provided
clamp (c)
7. before the cladding is complete connect the electrical
cables of the light and/or fan, since everything to be done
afterwards can be done form the outside.
If limitations of space make it impossible to use the bracket provided,
proceed in any case so that the kit is firmly fastened, using the recessed
box (optional).
It is advisable to:
Limit the ducting to 2 linear metres for natural
ventilation, and 8 linear metres for forced ventilation.
For natural ventilation, it is advisable to position the air outlets
at a height of not less than 2 m above the floor. (fig.3).
For forced ventilation, the kit can also be positioned at a
certain distance from the fireplace stove (max 8 m). In this case,
you must properly insulate the ducts so that the heat is not
dispersed and heats only the masonry.
If possible, provide ducts of the same distance to prevent
different quantities of air at different outlets.
For both natural and forced ventilation, it is advisable to
duct the front air outlets (A) where more heat
accumulates than at the rear outlets (P).
