Abstract
A power gas burner includes a plenum having front and rear walls and a side wall. A blast tube is connected to the front wall communicating with the plenum. A blower has its discharge connected to the plenum. An air-gas mixing tube is disposed in the blast tube with its discharge adjacent the distal end thereof and its inlet extending into the plenum, the mixing tube defining a secondary air passage with the blast tube. The mixing tube has an air-admitting opening adjacent its inlet communicating with the plenum. A gas line extends into the inlet of the mixing tube. A spider supports the discharge of the mixing tube and has legs engaging the distal end of the blast tube. A flame spreader disc is spaced from the discharge of the mixing tube, the diameter of the disc being generally equal to the diameter of the mixing tube at its discharge. The disc is mounted on one end of a rod extending through the air passage, the plenum and the rear wall, the rod being adjustably supported for selective longitudinal movement of the disc between a position spaced from the discharge of the mixing tube and a position outwardly from the rear wall for manual adjustment of the disc between the positions thereof. A sleeve on one of the spider legs slideably supports the other end of the rod.
