Burner type and capacity graph
Burner and heat exchanger must be matched.
Check burner type and burner capacity.
Installation location
Prior to installation ensure that:
the space for the burner hinging range is sufficient [ch. 3.4.7],
sufficient combustion air is available, if necessary install ducted air intake,
Prepare heat exchanger
The refractory

must not protrude beyond the front edge of the combustion head.
The refractory can take a conical shape (min 60°).
Refractory may not be required on boilers with water-cooled front, unless the man-
ufacturer gives other instructions.
Following installation, the aperture

between flame tube and refractory should be
filled with flame-proof, resilient insulating material. Do not make solid.
Heat exchangers with deep refractories or thick doors, or heat exchangers with re-
verse flame combustion chambers may require a combustion head extension. Head
extensions of 100, 200 and 300 mm are available. Dimension
