The firing rates has been obtained based on test boilers in accordance with EN267 standards and are indicative of matching the burner to the
boiler. For the correct operation of the burner, combustion chamber dimensions must be in accordance with current regulation. In case of non-
compliance, contact the manufacturer.

FLAME TUBE LENGTH
Flame tube length must be selected based on the specifications supplied by boiler manufacturer and, in any case, it
must be greater than the thickness of the boiler door included its insulation. In case of boilers with flame inversion or
front flue combustion chambers, it is necessary to insulate the area between the flame tube and front door with
refractory material. This protection material must not impede flame tube extraction.
