air to guarantee proper combustion.
There must be an outside air intake to guarantee
the flow of combustion air to the appliance and/
or recirculation of the ambient air.
The air intake must be properly rated and protected
by an anti-insect grate; it must also be positioned in
such a way that it cannot be accidentally obstructed.
In accordance with local regulations in force, there
are two possible configurations for the combustion
air intake:

ducted all the way to the furnace. Bottom
grate supplied standard for ambient air recir-
culation (A) on the cladding;
• (Fig. 5.7b): air intake on cladding (F)
ducted all the way to the furnace. Bottom grate
supplied standard on cladding (A) and hole in
wall (B) for ambient air recirculation.
The fireplace is supplied standard with a special flange
(D) on the right-hand side, with diameter 120 mm,

the product must be positioned on the top part of the

In the case in the room where is located the fireplace
there are one or more extraction fans operating
(suction hoods) malfunctions to the combustion may

5.8 Hood liner

For constructing the hood liner it is recommended to
use flame retardant plasterboard .
Before creating the hood liner, the control unit must
be installed.
During creation of the hood it is essential to protect the
door sliding frame with nylon to prevent dust, mortar
or other foreign bodies damaging the sliding system.
Remove the protection when the work is completed.
Make suitable side openings for the inspection of
parts.
Before carrying out the final assembly it will be
advisable to carry out a smoke test, i.e. to test the
operation of the appliance.
