appliance is hot (nominal calorific power). When the pressure exceeds 17 Pascal, it is necessary to reduce it through the installation of an
additional draught regulator (false air valve) on the exhaust pipe or in the chimney, according to the regulations in force.
For correct appliance operation, it is essential that sufficient air for combustion is introduced into the place of installation (see paragraph 8).
7.3.

CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE

The flue gas channel is the stretch of piping which connects the thermo-product to the flue. In the connection, these simple but extremely
important principles must be respected:
• under no circumstances use a flue gas channel with a diameter less than that of the exhaust clamp with which the thermo-product is
equipped;
• each metre of the horizontal stretch of the flue gas channel causes a slight loss of head which must be compensated if necessary by
elevating the flue;
• the horizontal stretch must never exceed 2 metres (UNI 10683);
• each bend of the flue gas channel slightly reduces the flue draught which must be compensated if necessary by elevating it suitably;
• The UNI 10683 – ITALY regulation requires that under no circumstances must there be more than 2 bends or variations in direction
including the intake into the flue.
If the user wishes to use the flue as a fireplace or open hearth, it is necessary to seal the hood below the entrance point of the flue gas
channel pos. A Picture 5 at page
If the flue is then too big (e.g. 30x40cm or 40x50cm), it is necessary to intubate it with a stainless steel tube with a diameter of at least
200mm, pos. B, taking care to close the remaining spaces between the pipe and the flue immediately under the chimney pot pos. C.

8. AIR FLOW IN THE PLACE OF INSTALLATION DURING COMBUSTION

As the thermo-product draw their combustion air from the place of installation, it is MANDATORY that in the place itself, a sufficient quantity
of air is introduced. If windows and doors are airtight (e.g. built according to energy saving criteria), it is possible that the fresh air intake is
no longer guaranteed and this jeopardises the draught of the appliance and your health and safety. It is therefore necessary to guarantee
a supply of fresh air through an external air inlet placed near the appliance or by placing piping for combustion air which leads outside or
to a nearby airy place, with the exception of the boiler room or garage (FORBIDDEN).
IMPORTANT: For a better comfort and corresponding oxygenation of environment, the stove / insert combustion air can be directly
withdrawn at the outside. In order to do that, the stove can be connected to the external air socket by an junction (Chap. TECHNICAL
DATA SHEET pos.A).
The connection pipe must be smooth with a minimum diameter of 100 mm. It must have a maximum length of 4 m and have no more than
three bends. If it is directly connected to the outside, it must be equipped with a suitable windbreak.
The intake of air for combustion in the place of installation must not be obstructed during operation of the thermo-product. It is absolutely
essential that in environments in which thermo-products are operated with a natural chimney draught, as much air as is necessary for
combustion is introduced, i.e. up to 20 m³/hour. The natural recirculation of air must be guaranteed by some fixed openings to the outside.
Their size is established by regulations regarding the subject. Ask for information from a chimneys weep. The openings must be protected
with grills and must never be blocked up. An extractor hood (suction) installed in the same room or in a neighbouring one causes a
depression in the environment. This causes the leakage of burnt gas (dense smoke, smell); it is therefore necessary to ensure a greater
flow of fresh air.
The depression of an extractor hood can, in the worst case scenario, transform the flue of the thermo-product into an external
air inlet, re sucking the flue gases into the environment with very serious consequences for persons.

9. CANALIZATION OF THE WARM AIR

The heat distribution will take place through the ventilation of the installation environment, or of the adjacent room by the connection in the
back of heat resistant ventilation pipes.
Therefore, during installation, it is necessary to establish the type of ventilation or convection to be adopted
Configuration A - Ventilation:
a) Warm air output ONLY from the front side of the appliance: do NOT remove the semi-blanks
b) Adjust through the register C
Configuration B - Ventilation and CANALIZATION:
Warm air output from the front and rear side of the appliance: REMOVE the semi-blanks
a)
b) Perform the drilling on the walls to allow the passage and the application of the (fire-resistant) hoses equipped with related openings.
c) Fasten the pipes by means of clamps to the related collars and openings.
d) Each pipe must not exceed 4 m for forced ventilation, and has to be insulated with insulating materials to avoid noise and loss of
heat.
e) The openings have to be positioned at a height not lower than 2 m from the floor to avoid that hot air at output meets people; Please
respect the distance of the convection openings according to the local construction norms.
f) The lengths of the canalization pipes must have the same length to avoid the distribution of differing quantities of air from each
output. (see Picture 6 at page 44
