Abstract
A modular flue adapter system and method is described to accommodate a conduit for exhaust between a firebox and a firebox flue, wherein the firebox is inserted into a firebox opening, by providing an offset distance and/or direction between the exhaust of the firebox and the firebox flue.
Claims14
A modular device configured to facilitate an engagement of a firebox to a chimney exhaust, comprising:
- a first portion configured to be adjustably coupled to the firebox, said first portion configured to slidably engage into a receivable slot of the firebox and to provide an offset distance between a firebox exhaust output and said chimney exhaust in at least one of a negative offset direction and a positive offset direction relative to a rear wall of the firebox;
- and
- a second portion coupled to said first portion and defining a conduit for exhaust between the firebox and the chimney exhaust, said second portion configured to be removably coupled to a firebox mounting plate;
- wherein said first portion and said second portion comprise separate components that are selected and coupled to accommodate the offset distance and offset direction, and
- wherein upon insertion of said modular device into the firebox, said modular device is at least partially internal within the firebox.

A heating system comprising:
- a firebox comprising:
- a mounting plate located in a first plane of said firebox;
- an exhaust output passageway configured within said mounting plate;
- a receivable slot located in a second plane of said firebox;
- an exhaust output comprising said exhaust output passageway and an elongated opening in said second plane, said exhaust output extending from and communicating with said exhaust output passageway and configured to receive a modular device selected from a plurality of modular devices, each modular device configured to provide an offset distance between said exhaust output and a chimney exhaust in one of a negative and a positive offset direction relative to the first plane;
- and
- the modular device, comprising:
- a first portion configured to slidably insert within said receivable slot of said firebox;
- and
- a second portion comprising an adapter plate configured to be removably coupled to said firebox mounting plate;
- wherein said first portion and said second portion comprise separate components,
- wherein said second portion is coupled to said first portion such that said modular device defines a conduit for exhaust between said exhaust output and said chimney exhaust, and
- wherein upon insertion of said modular device, said adapter plate of said second portion abuts said firebox mounting plate to provide a seal, and said modular device is at least partially internal within said firebox.
10 more elements
A method for adapting a firebox flue to a chimney exhaust, said method comprising:
- determining an offset distance needed between said firebox flue and said chimney exhaust based on a selected position for a firebox;
- selecting from a plurality of modular devices, said modular device comprising a first portion and a second portion, said second portion comprising an adapter plate and a firebox flue;
- providing a firebox comprising a receivable slot;
- connecting said firebox to said modular device, wherein said modular device is inserted into said receivable slot such that said modular device is at least partially internal within said firebox, and wherein said firebox flue is positioned at said offset distance;
- and
- connecting said firebox flue to said chimney exhaust such that said firebox is in fluid communication with the chimney exhaust.
