5. Site conditions and technical configuration may affect the burner matching, and therefore these selections should be used as a guide only.  For example if the boiler has a reverse flame chamber then the burner may require an extended combustion head.  Riello Limited cannot accept responsibility for incorrect burner matchings unless full application details are known.
