Abstract
Abstract There is disclosed an integral three section gas burner construction and controls including automatic sequential lighting of the sections on demand and air supply structure. A pilot unit ignites a first burner section when gas is supplied. The first burner section includes some burners adjacent to a second and a third burner section, said second burner section and said third burner section being ignited from said respective adjacent burners of said first burner section on demand for more heat and supply of gas. Each burner section has a separate compartment for the supply of secondary air to the burners.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
189 words
In combination, a burner construction comprising supporting means, a plurality of burner sections supported thereby, each burner section including at least three burner assemblies, pilot means for igniting the burner assemblies of a first burner section, and means for igniting the burner assemblies of a second burner section directly from a burning burner assembly of the first burner section, said means comprisinG at least one burner assembly of said first burner section positioned closely adjacent to at least one burner assembly of the second burner section for ignition of gas from the latter by flame from the former on demand and means for igniting sequentially predeterminately the second burner section and the third burner section directly from predetermined burning burner assemblies of the first burner assembly, the burner assemblies of the first section being disposed generally in the form of a ''''I'''' with the stem thereof intermediately positioned and closely adjacent to the burner assemblies of each of the second and third sections, said third burner section bounding said second section and ignitable by it as well as by the burner assemblies in the stem of said first section.
Claim 2
Dependent Claim
189 words
In combination, a burner construction comprising supporting means, a plurality of burner sections supported thereby, each burner section including at least three burner assemblies, pilot means for igniting the burner assemblies of a first burner section, and means for igniting the burner assemblies of a second burner section directly from a burning burner assembly of the first burner section, said means comprisinG at least one burner assembly of said first burner section positioned closely adjacent to at least one burner assembly of the second burner section for ignition of gas from the latter by flame from the former on demand and means for igniting sequentially predeterminately the second burner section and the third burner section directly from predetermined burning burner assemblies of the first burner assembly, the burner assemblies of the first section being disposed generally in the form of a ''''I'''' with the stem thereof intermediately positioned and closely adjacent to the burner assemblies of each of the second and third sections, said third burner section bounding said second section and ignitable by it as well as by the burner assemblies in the stem of said first section.
Claim 3
Dependent Claim
80 words
The combination of claim 1 and including a supported transverse header for receiving gas from a gas line, a first set of branch manifolds communicating said header and the first section burner assemblies forming the head of the ''''T,'''' a second branch manifold communicating said header with a predetermined number of burner assemblies of the stem of the ''''T,'''' and a third branch manifold communicating said header with another predetermined number of burner assemblies of the stem of the ''''T.''''
