Burners and controls
Prefer a specific burner? We’ll give you options.
New McKenna boilers come with a burner matched to the boiler and the emissions limit, and Autoflame controls come as a standard option. If you or your engineer prefer a specific burner, we’ll quote it along with other options so you can compare. We also install, set up, and tune burners and controls from other manufacturers, including one your engineer already specified. For boilers of 2,000,000 Btu/hr or less, we have units pre-certified to South Coast AQMD Rule 1146.2.
Want a recommendation? We’re a factory-authorized Limpsfield Burner Tech Center and Autoflame Tech Center, and we can recommend Power Flame burners. We don’t sell for a manufacturer, so we’ll tell you what your plant actually needs.
