In the case of CF application, combustion air is fed through the
feeder unit (A).
In the case of BF application, combustion air is fed through a flexible
or rigid pipe connected to the air intake (B).
FOR CORRECT BF APPLICATION, THE BURNER MUST BE
INSTALLED ON AN APPROPRIATE BF BOILER.
Consequently, you must comply with the following requirements and
instructions:
➤
The combustion air intake tube must be:
- fastened securely to the burner;
- made of a suitable material, with temperature characteristics in
the range - 30 °C to 80 °C;
