Natural Draft Burners

O-Type Burner

The O-type burner is the economic choice for a unit under 3.0MM BTU. O-types are typically used for a single firetube application.

Two Piece Burner

The two-piece burner was created for protecting the flame cell when inspection and recovery of parts is necessary. The hinged, two-piece design is especially useful on bigger units (28" and larger).

Box Type Burner

The box-type burner was designed to be able to reach a higher BTU rating while taking up minimal space. This compact design utilizes multiple flame cells in close quarters in order to get the desired BTU rating.
