The Series 900 Steam Boiler is manufactured to exceed ASME Section IV standards and typically is used to provide operating pressure of up to 15 psi with nominal operating temperature of 218°F to 240°F. These vessels contain 37 vertical firetubes, each of which is 1½” diameter, each fitted with a high-efficiency turbulator for maximum heat transfer. The combustion chamber is fully water-backed, with burners that are UL listed. This boiler qualifies as a Category I gas appliance with industry standard controls wired to NEC specifications.

A well-made, heavy vessel is naturally a safer boiler. But Superior Boilers also have a firebox design that is completely backed by water, along with extra safety controls on the boiler that results in a very safe and secure package.
