Abstract

A pilot and burner assembly includes a burner assembly and a blower for supplying combustion air to the burner assembly. The system further includes a pilot assembly and a fuel supply for providing fuel to the pilot assembly. A pilot fan provides pilot air to the pilot assembly, the pilot fan being separate from the blower and provides air only to the pilot assembly.
