Abstract
Abstract This is a new fireplace, which is either constructed in place or is totally prefabricated in advance and placed within a building where desired. The fireplace is particularly characterized by a pair of overlapping hollow members placed within the throat of the fireplace above the combustion chamber, wherein one of the hollow chambers receives cool air which is heated and then expelled for use, and a second chamber in which an arrangement of tubular members is embedded carrying water into the tubular arrangement for purposes of heating and then bringing the water out of the fireplace. A humidifying liquid is presented into the first chamber and an adjustment for changing the size of the throat is also provided. A method of constructing and assembling the fireplace, or combustion apparatus, in such a manner that it can be prefabricated away from the site of installation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
The method of assembling a combustion apparatus of the type containing a fuel burning chamber, a circulated air chamber with a humidifier incorporated therewith, and a heat sink mechanism for heating adjacent fluid conduit transporting apparatus which includes: (1) placing a fire and heat resistant base means upon a supporting surface; (2) providing a first fire and heat resistant combustion chamber liner means upon said base; (3) placing a first support means upon said combustion chamber liner means; (4) supporting a circulated air chamber means having a humidifier means incorporated therewith onto said first support means; (5) Stacking, in alignment, a second fire and heat resistant chamber liner means atop said first combustion chamber liner means; (6) placing a second support means upon said said second chamber liner means; (7) Supporting a combination heat sink means and adjustable damper means upon said second support means; (8) Installing a fluid transporting conduit means adjacent said heat sink means; and (9) stacking, in alignment, a fire and heat resistant vented closure means atop said second chamber liner means.
Claim 2
Independent Claim
176 words
The method of assembling a combustion apparatus of the type containing a fuel burning chamber, a circulated air chamber with a humidifier incorporated therewith, and a heat sink mechanism for heating adjacent fluid conduit transporting apparatus which includes: (1) placing a fire and heat resistant base means upon a supporting surface; (2) providing a first fire and heat resistant combustion chamber liner means upon said base; (3) placing a first support means upon said combustion chamber liner means; (4) supporting a circulated air chamber means having a humidifier means incorporated therewith onto said first support means; (5) Stacking, in alignment, a second fire and heat resistant chamber liner means atop said first combustion chamber liner means; (6) placing a second support means upon said said second chamber liner means; (7) Supporting a combination heat sink means and adjustable damper means upon said second support means; (8) Installing a fluid transporting conduit means adjacent said heat sink means; and (9) stacking, in alignment, a fire and heat resistant vented closure means atop said second chamber liner means.
Claim 3
Dependent Claim
151 words
A combustion apparatus of the type containing a fuel burning chamber, a circulated air chamber with a humidifier incorporated therewith, and a heat sink mechanism for heating adjacent fluid conduit transporting apparatus which includes: a fire and heat resistant base means; a first fire and heat resistant combustion chamber liner means placed upon said base means; a first support means placed upon said first combustion chamber liner means; a circulated air chamber means having a humidifier means incorporated therewith; a second fire and heat resistant chamber liner means placed atop said first combustion chamber liner means; a second support means placed upon said second chamber liner means; a combination heat sink means and adjustable damper means placed upon said second chamber liner means; a fluid transporting conduit means located adjacent said heat sink means; and a vented fire and heat resistant means stacked in alignment upon said second chamber liner means.
Claim 4
Dependent Claim
151 words
A combustion apparatus of the type containing a fuel burning chamber, a circulated air chamber with a humidifier incorporated therewith, and a heat sink mechanism for heating adjacent fluid conduit transporting apparatus which includes: a fire and heat resistant base means; a first fire and heat resistant combustion chamber liner means placed upon said base means; a first support means placed upon said first combustion chamber liner means; a circulated air chamber means having a humidifier means incorporated therewith; a second fire and heat resistant chamber liner means placed atop said first combustion chamber liner means; a second support means placed upon said second chamber liner means; a combination heat sink means and adjustable damper means placed upon said second chamber liner means; a fluid transporting conduit means located adjacent said heat sink means; and a vented fire and heat resistant means stacked in alignment upon said second chamber liner means.
Claim 5
Dependent Claim
37 words
The apparatus as set forth in claim 2 in which said first fire and heat resistant combustion chamber liner means is provided with controlled openings for fuel insertion and for venting of air to aid in combustion.
Claim 6
Dependent Claim
