Fibrous mat type burner can have mat pieced together with butt joints and very thin layer of resinous sealant uniting the pieces at the joint. Burners with elongated mats are thus readily manufactured, and can be packaged strapped together in pairs face-to-face and enclosed in telescoping carton halves that allow for packaging burners of different lengths. Matrix edges can be held by clamping members that are curved where they engage outer face so that they do not dig into that face, but dig into inner matrix face. Ceramic mats can be mounted around burner so that they are heated by hot burnt gases and their heated faces generate supplemental radiation toward work being heated by burner.
