Abstract
A burner assembly is provided including a plurality of burners. Each burner includes a burner tube having an inlet, an outlet, and a burner axis. A partition plate is arranged generally perpendicular to a horizontal plane defined by the plurality of burner axes. The partition plate includes a plurality of partition openings complementary to and arranged coaxially with the plurality of burners. An igniter is located near the plurality of burners and is configured to ignite a fuel and air mixture provided at the outlet of the burners. An ignited carryover includes a substantially identical first opening and second opening formed in the partition plate adjacent the igniter. The first opening and second openings are sized such that a sufficient amount of the fuel and air mixture reaches the igniter without cooling the igniter.
