EXAMPLE OF AIR DUCTING AND BOILER HOOD FOR HOT WATER PRODUCTION
The air ducts must be run to the rooms you want to heat.
Each room heated in this way must guarantee the return of air
to the room with the fireplace by means of gaps under the door
(1 cm min) or special vents.
The air is distributed by means of circular-section, flexible tubes
made from aluminium with sheet metal fittings and deviators.
These tubes must be fixed to the fittings by means of tube
clamps.
These tubes must be insulated in order to guarantee top per-
formance of the fireplace. These should thus be fully lined with
glass-wool blankets (min 3 cm thick).
Never use plastic tubes to distribute the hot air, as the high
temperature of the air could melt these.
Where it's impossible to run the tubes in the wall, you can
create a false ceiling, false beams or boxes.
Important: Always seal the joint between the outlets and the wall
(with silicone, see pag. 9) to prevent air from escaping at these
points and so darkening the surrounding surfaces due to the
heat.
For better efficiency, fit an adjustable air vents (ø 120) in the
base of fireplace to allow the ventilator to intake 50% air from the
room.
