Abstract

A catalytic combustor assembly includes a housing containing a catalytic combustor for insertion into the firebox of an existing stove. The housing engages and hermetically seals against the ceiling of the firebox surrounding the flue outlet of the stove to define an airtight passageway for volatile gases from the firebox to the flue outlet. The housing further defines a pair of secondary combustion air inlets and connected conduit for heating and then directing secondary air into the defined passageway to mix with the volatile gases upstream of the catalytic combustor. A bypass door is also mounted within the housing for selectively allowing the volatile gases to bypass the combustor in passing from the firebox to the flue outlet.
