Commercial boilers

The burner-boiler combination poses no problems if the boiler
conforms to EN 303 and its combustion chamber dimensions are
similar to those provided in EN 267.
If, on the other hand, the burner is combined with a commercial
boiler that does not conform to EN 303, or where the combustion
chamber is much smaller than the dimensions set out in EN 267,
please contact the manufacturers.
