(*) The proposed value are indicative. This appliance must be connected to (1) a listed Type HT (2100°F) chimney per UL 103 or ULC S629, or
(2) a code-approved masonry chimney with a flue liner. The chimney size should not be less than or more than three times greater than
the cross-sectional area of the flue collar.
(**) For those buildings in which the thermal insulation does not correspond to the instructions on heat protection, the heating volume of
the product is: favourable type of building (30 kcal/h x m
(50 kcal/h x m ).

(***) When the depression exceeds 15 Pa (=1.5 mm of column of water), it is necessary to reduce the same by installing an an
appropriate device on the exhaust pipe or in the chimney, according to the regulations in force.
With thermal insulation in accordance with the regulations regarding energy saving, the heated volume is greater. With temporary
heating, in the event of interruptions which last more than 8 hours, the heating capacity is reduced by about 25%.
The declared technical data have been achieved by burning beech wood class "A1" according to the requirement UNI EN ISO 17225-5 and
wood moisture content less than 20%. By burning a different kind of wood the efficiency of the product itself could change and some specific
adjustments on the appliance could be needed.

2.2.2 CALCULATION OF THE THERMAL POWER

There is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but it
depends also largely on the insulation. On an average, the calorific value necessary for a properly insulated room is 30 kcal/h per m
external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 35 W/m
Let's suppose one wishes to heat a room of 150 m
W/m = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
