Operation Manual

Solution 4 - Fig. 34:
Extension of the previous solution, with the stove installed in the room
to be heated and the air ow ducted to the front and the rear, but using
a second Y-element to double the ducting at the rear as shown.
Maximum total length of the hoses 50’ / (15 m). (Fig. 34).
a For the example shown in g. 34, for efcient ducting and to
avoid overheating, it is necessary to use non-closable outlet
vents as shown. During operation the outlet vent closest to the
Y-element must be partially open but never closed to avoid
overheating.
Wall and oor ducting - Fig. 35 / 38
For efcient ducted heat distribution:
- lag the hose with a 0.79” / (2 cm) thick insulation (e.g. mineral
bre, ceramic bre, rock bre) to limit heat loss and to guarantee a
sufciently warm air temperature;
- the insulation must have a speci c weight equal to or more than 50
kg/m³ with working temperature limit of at least 482°F / (250°C).
Thermal conductivity λ (100°C) ≤ 0,050 W/mK.
- Material with code “AGI Q132” or “DIN 18895” is allowed for thermal
insulation;
- the maximum total length of the hose connected to the 2 fans must
not exceed 32.8’ / (10 m).
a If the insulating material is not enclosed under the oor or
within the walls, it must be xed to the surface with suitable
fastenings at intervals of 11.8” / (30 cm).
A few examples of how the hose can be installed in walls or oors are
given to the side.
Safety ducting distance - Fig. 39
When hot air is to be ducted using a Ø 3” / (Ø 75 mm) exible pipe to
adjoning rooms the minimum lenght shall not be under 4” / (10 cm)
which corrisponds to the minimum distance allowed from the wall to
rear of the stove.
If the exible pipes go throught combustible walls and ceilings the
minimum required clearance is 1/2” / (1,3 cm).
Such space if made by air is allowed but it is reccomended to ll this
space with insulation (e.g. mineral bre, ceramic bre, rock bre)
wrapped around the exible pipe.
a The exible pipes are hot while in operation. If they aren’t
insulated and pass through a room (typically in the space
behind the stove) keep children, clothing and furniture away.
Contact may cause skin burns.
Hot air outlet vent radiation area (mm) - Fig. 40
A safety area must be ensured around the hot air outlet vent within
which there must be no ammable objects (furniture, carpets, curtains,
etc.) or heat sensitive materials (wood, plastic, etc.).
The diagram to the side shows the measurements for this safety area,
which includes 23.6” / (600 mm) from the upper edge of the vent.
a If the oor is ammable, the hot air outlet vents must be
located at least 7.9” / (200 mm) from the oor.
