I have a 31yr old Burnham gas hot water boiler. I worked fine for almost 30 years, but last year and again starting this year,there is a slight flame roll out. It causes the front to soot up and there is increased heat in the front of the boiler with the cover off. I cleaned the boiler and there appears to be no leaks. It almost seems to be drafting poorly. I need some ideas. Thanks.
