Performance Curves

To get the input in kcal/h, multiply value in kW by 860. Data are referred to standard conditions: 1013mbar, 15°C

Fan installation

Connect the air duct to the burner by means of the bellows unit provided together with the burner (see the picture below).

Performance range

ATTENTION! The bellows unit provided is made of canvas and is provided with blocking spacers to avoid brea-
king it during installation: first place the bellows unit between flanges, then remove the spacers. Canvas has to
be stretched after the installation, but not stressed.
ATTENTION! the air duct dimensioning must be perforformed according to the flow rate, the temperature, the
distance between the fan and the burner and according to the fan features as well..
ATTENTION! It is suggested to install the fan on vibration-damping supports in order to reduce vibration propa-
gation.
