Anti-downdraught terminal:
An anti-downdraught terminal must be installed to
avoid the backflow of fumes.
Draught in the chimney:
The following figures show three standard diagrams
containing the correct length and diameter specifications. Any other type of
installation that you choose to perform must guarantee a draught of 12 Pa
(0.12mbar) measured at maximum heat and power.
Ventilation:
For the boiler’s correct operation it is necessary to have an air inlet
with a minimum section of 100cm
2
available at the installation location,
preferably near the rear panel of the unit.
The boiler is equipped with a round pipe
(
50mm) that may be connected to the exterior of the house.

Installation with a chimney
As shown in Figure 8, the
100mm exhaust pipe of the pellet boiler is installed
directly on to the chimney. If the chimney is too large, we recommend that you attach
an
80mm pipe to the fume outlet.
You should also consider attaching a T-tube to the base of the pipe to allow for
periodic inspection and annual maintenance, as illustrated in Figure 8.

We do not recommend that you use the boiler in rough weather conditions that may
seriously impact the draught (particularly with very strong winds).
