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 con-
form to EN 303, or where the combustion chamber is much small-
er than the dimensions set out in EN 267, please contact the
manufacturers.
