ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to prefabricated sheet metal wood burning fireplaces for use in an exposed outdoor environment. More particularly, the present invention relates to a rust proof and weatherproof outdoor fireplace for burning wood and for conversion to burning gas.
2. Description of the Prior Art
Wood burning stoves and wood burning fireplaces are well known in the prior art and are classified in Class 126 subclasses 77, 85, 92, 193, etc.
Prefabricated fireplaces for burning wood are known to be designed for conversion to burn gas with the addition of a gas burner and controls for supplying proper gas flow to the gas burner. Such fireplaces have heretofore been installed inside of a house in a protective environment even when placed in a wall where they can be seen from the outside.
It would be desirable to provide a fireplace with an attractive outer enclosure which could be used completely outside of a house such as placed on a patio or deck and be immune to hostile adverse weather conditions such as rain, sleet, snow and ice accompanied by heavy wind and yet always be ready for use as an outdoor fireplace.
SUMMARY OF THE INVENTION
It is a primary object of the present invention to provide a universal outdoor fireplace capable of stand alone use outside of a house or for being placed in or against an outside wall of a house.
It is a primary object of the present invention to provide a wood burning fireplace for outside use that may be converted to a gas burning fireplace.
It is primary object of the present invention to provide a wood-burning fireplace that may be left outside in hostile weather conditions.
It is a general object of the present invention to provide an outside universal wood burning fireplace that is rust proof and convertible to an outside gas burning fireplace and can be used as an outside/inside fireplace.
According to these and other objects of the present invention there is provided a prefabricated fireplace having an outside rust proof ornamental shroud or cover attached to a double panel inner fireplace unit. The inner fireplace unit comprises a combustion chamber box that is lined with ceramic material at the vertical sides and at the floor. The ceramic floor s supported in a horizontal plane juxtaposed the floor panel of the combustion chamber which is inclined from rear to front to prevent water entrapment. A novel waterproof compartment is constructed below the floor panel.
