6.2. CONNECTION TO THE CHIMNEY

Products with automatic door closing (type 1) must operate, for safety reasons, with the furnace door closed (except during the fuel loading

or ash removal phases).

Products with non-automatic door closing (type 2) must be connected to their own ue.

Operation with doors open is only allowed when supervised.

The connection pipe to the ue must be as short as possible, straight horizontal and positioned slightly in ascent, and watertight.

Connection must be carried out with stable and robust pipes,comply with all current Standards and Regulations and to those envisioned

out when the appliance is hot (nominal caloric 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 sufcient air for combustion is introduced into the place of installation (see paragraph 7).

6.3. CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE

The ue gas channel is the stretch of piping which connects the product to the ue. In the connection, these simple but extremely important

principles must be respected:

• under no circumstances use a ue gas channel with a diameter less than that of the exhaust clamp with which the product is equipped;

• each metre of the horizontal stretch of the ue gas channel causes a slight loss of head which must be compensated if necessary by

elevating the ue;

• the horizontal stretch must never exceed 2 metres (UNI 10683);

200mm, pos. B, taking care to close the remaining spaces between the pipe and the ue immediately under the chimney pot pos. C.

7. AIR FLOW IN THE PLACE OF INSTALLATION DURING COMBUSTION

As the product draw their combustion air from the place of installation, it is MANDATORY that in the place itself, a sufcient 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).

The intake of air for combustion in the place of installation must not be obstructed during operation of the product. It is absolutely essential

that in environments in which products are operated with a natural chimney draught, as much air as is necessary for combustion is

introduced, i.e. up to 20 (<11kW) m³/hour. The natural recirculation of air must be guaranteed by some xed openings to the outside. Their

Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 3 logs should be loaded. The pieces of wood

should have a length of ca. 20-30 cm and a maximum circumference of 30-35 cm.

Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may damage the device, since

these have a very high caloric value.

The wood used as fuel must have a humidity content lower than the 20% and must be stored in a dry place. Humid wood tends to burn

less easily, since it is necessary a greater quantity of energy to let the existing water evaporate. Moreover, humid content involves

the disadvantage that, when temperature decreases, the water condensates earlier in the hearth and therefore in the stack causing a

remarkable deposit of soot with following possible risk of re of the same.

Fresh wood contains about 60% of H
