Abstract: A system and method for facilitating clustering of ads and map content, the method including receiving a request associated with a target region on a map from a user device, identifying an ad for display to a user based at least in part on the received search request, determining a location associated with an ad of the one or more ads, determining a region criteria based on the location of the ad, retrieving, one or more map content items having a location meeting the determined region criteria, comparing the ad and the retrieved one or more map content items to identify a map content item associated with the same entity as the ad and providing the ad and the identified map content item to the user at the user device, wherein the map content item is displayed as a single entity with an identifier of the map content item.

Abstract: In a heating apparatus of the type including a multiplicity of spaced, independent burners arranged in a single plane between a pair of manifolds which conduct air and gas to the burners, there is disclosed an improved ignition carry-over wherein the burners are arranged in a non-parallel, zig-zag pattern with the first end of each burner spaced relatively closely to the first end of the adjacent burner on one side thereof and spaced relatively far from the first end of the adjacent burner on the other side thereof whereby the flame readily jumps from one burner to the next.
