Abstract
A burner assembly for use adjacent an igniter element in a gas appliance includes a top plate configured to form the geometric top half of at least one burner, and a bottom plate configured to form the geometric bottom half of at least one burner. The top plate and the bottom plate are joined together to form a burner and a burner carryover. An igniter air shield extends from either the top plate or the bottom plate such that the igniter air shield diverts secondary combustion air flowing around the burner and the adjacent igniter element.
Claims17
A burner assembly for use adjacent an igniter element in a gas appliance comprising:
- a top plate configured to form the geometric top half of at least one burner;
- a bottom plate configured to form the geometric bottom half of at least one burner, wherein the bottom plate and the top plate are joined to form a burner and a burner carryover;
- and
- an igniter air shield extending from one of the top plate or bottom plate such that the igniter air shield diverts secondary combustion air flowing around the burner carryover and away from the adjacent igniter element.
A burner unit comprising:
- a burner assembly having a plurality of axially aligned burners;
- a burner box for receiving the burner assembly;
- an igniter assembly including an igniter element, wherein the igniter assembly is mounted to the burner box such that the igniter element is adjacent the burner assembly;
- and
- an igniter air shield extending from a portion of the burner assembly, such that the igniter air shield diverts secondary air flowing around the burner assembly away from the igniter element.
A furnace comprising:
- a burner assembly having a plurality of axially aligned burners;
- a burner box for receiving the burner assembly;
- an igniter assembly including an igniter element, wherein the igniter assembly is mounted to the burner box such that the igniter element is adjacent the burner assembly;
- and
- an igniter air shield, extending from the burner assembly, for diverting secondary air flowing around the burner assembly away from the igniter element.
