Fig. 104 - 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.
6.19 USING THE STOVE WITHOUT DUCTING (ATENA
3
PLUS 12/14 - DUKE 12/14 AIRTIGHT - SABA
12/14)
The stove can be used without ducting the air to other environments.
In this case, assemble the environment diffuser in the stove's rear (where the ducting outlet is foreseen) (see
Fig. 105
).
