• Position the pipes as shown in
• Fasten the pipes for the rear hot air outlet (see
).
Fig. 67 - Ducting system example
• A stove with no ducting has a variable air flow rate from a minimum of 59 m
3
/h to a maximum of 153 m
3
/h, and an air tem-
perature which varies from a minimum of 90°C to a maximum of 150°C; these data are valid for each of the 2 outputs and the
fan of the central environment.
• In the case of ducting, it is recommended not to exceed 8 metres of pipe and 3 x 90° bends, otherwise the hot air loses its
effectiveness.
• Use pipes with an 80 mm diameter with smooth internal walls.
• If the pipes pass through cold walls, insulate the pipe with insulating material.
• Place a protective grille with large mesh and a total minimum net surface area of 24 cm
2
over the outlet.
• There can be a variable air flow rate from a minimum of 35 m
3
/h to a maximum of 80 m
3
/h and an air temperature which
varies from a minimum of 40°C to a maximum of 100°C after the 8 metres of pipe. (These values were recorded in the testing
laboratory; there may be differences in flow and temperature in the installation room).
• If you wish to increase the air flow, install a small wall-mounted fan on the outlet with a flow rate of more than 80 m
3
/h; this
should be performed by an authorised technician.
• With the factory parameters, 26% of the heat produced by the stove is conveyed into the room where it is installed and the
remaining 37% comes out from the ducting on the right and 37% from the left one.
• To get the best performance you need to balance the power with the air flow. This operation must be performed with the
assistance of an authorised technician.
• The ductable fans cannot be deactivated, but they can be operated at a power value between 1 and 5 or in automatic mode.
