Abstract: A dual fuel burner system includes a fuel burner housing and a main fuel supply conduit within the fuel burner housing. A main fuel nozzle is positioned proximate to a downstream end of the fuel burner housing and is in fluid communication with the main fuel supply conduit. The main fuel supply conduit is configured to provide 100% of the heat input requirement of the dual fuel burner system. A secondary fuel supply conduit is within the fuel burner housing. The secondary fuel supply conduit is configured to provide 100% of the heat input requirement of the dual fuel burner system. An air circuit is in fluid communication with an outlet of the main fuel nozzle. A direct spark ignitor is positioned proximate to the outlet of the main fuel nozzle.

Abstract: A diaper for a dog or other animal comprises a body band of sufficient length to be placed around the body of a dog that includes a fastening device such as Velcro to secure the body band about the waist of the dog. An elongate covering with stiffening member extends from the mid-section of the body band that is of sufficient length to cover the dog's genital area without overlapping the dog's anal area. Thus, normal bowel movement is not inhibited. The body band and the elongate covering are constructed of an inner layer consisting of a non-allergenic fabric to be disposed against the body and the genital area of the dog, a decorative outer layer to be exposed, and a moisture impermeable layer situated between the inner layer and outer layer to trap waste discharge. A pair of straps constructed of elastic material connect the body band to the elongate covering and maintain the covering and mid-section of the body band over the dog's genital area.
