Abstract
This invention provides a flammable fluid fuelled heater providing a direct opening into the primary combustion chamber to provide an unobstructed view of the fire. Any circulating means such as a fan may be provided adjacent the opening so as to provide an air curtain across the opening. This may limit the flow of air through the opening to reduce overall throughput as well as reducing spillage out the opening. In addition, the artificial log assembly in the fire may be arranged so that at least some of the logs meet collective surfaces at right angles so as to provide a visual continuity into the reflective surface and thereby provide a larger visual appearance to the fire.
Claims19
A flammable fluid fueled heater comprising:
- a primary combustion chamber having an opening in at least one side thereof for providing a view of a substantial portion of the primary combustion chamber;
- a flammable fluid fuel supply to said primary combustion chamber to, upon combustion, provide a substantial portion of yellow flame, wherein upon combustion exhaust gases are generated;
- a secondary combustion chamber in communication with the primary combustion chamber for receiving exhaust gases generated in the primary combustion chamber, the secondary combustion chamber comprising a catalytic converter;
- an exhaust port in communication with the secondary combustion chamber for redirecting at least a portion of the exhaust gases received into the secondary combustion chamber into a room where the heater is located;
- and
- an air circulating means for providing a stream of air across at least a portion of said opening.

A flammable fluid fueled heater comprising:
- a primary combustion chamber having an opening in at least on side thereof to provide a view of at least a substantial portion of said primary combustion chamber;
- a flammable fluid fuel supply to said primary combustion chamber to, upon combustion, provide a substantial portion of yellow flame and generate products of combustion;
- a secondary combustion chamber in communication with the primary combustion chamber for receiving products of combustion from the primary combustion chamber said secondary combustion chamber comprising a catalytic converter;
- an air circulating means for assisting in the drawing of the products of combustion through said secondary combustion chamber;
- and
- an exhaust port in communication with the secondary combustion chamber for receiving the products of combustion and exhausting at least a portion of said products into a room where the heater is located.
3 more elements
A flammable fluid fueled heater comprising:
- a primary combustion chamber;
- a flammable fluid fueled supply to said primary combustion chamber to upon combustion, provide a substantial portion of a yellow flame and generate products of combustion;
- an opening formed on the primary combustion chamber for exhausting the products of combustion;
- an artificial log assembly provided in said primary combustion chamber;
- at least one reflective surface provided on at least one side of said primary combustion chamber to provide a reflected view of said substantially yellow flame and artificial log assembly;
- and
- wherein said artificial log assembly provides at least one artificial log abutting said reflective surface, said artificial log having a longitudinal axis substantially parallel to said reflective surface and having a longitudinal upper edge abutting said reflective surface such that the artificial log and the apparent reflection of said log creates the appearance of a full round log.

A flammable fluid fueled heater comprising:
- a housing having an opening;
- a primary combustion chamber within the housing, the primary combustion chamber having an opening in at least one side thereof aligned with the housing opening providing a view of the combustion chamber from a location external to the housing;
- a flammable fluid fuel supply to said primary combustion chamber to, upon combustion, provide a substantially yellow flame;
- a secondary combustion chamber comprising,
- an intake in communication with the primary combustion chamber for receiving products of combustion from the primary combustion chamber,
- a catalytic converter, and
- an exhaust for exhausting the products of combustion;
- a duct between the housing and the primary combustion chamber for receiving air from a source external to the heater, the duct providing a flow of air over the exhaust;
- and
- an air circulating means for increasing the circulation of air through said duct for creating an air stream across the secondary combustion chamber exhaust for increasing the throughput through the catalytic converter.

- an artificial log assembly provided in said primary combustion chamber;
- at least one reflective surface provided on at least one side of said primary combustion chamber to provide a reflected view of said substantially yellow flame and artificial log assembly;
- and
- wherein said artificial log assembly provides at least one artificial log abutting said reflective surface said artificial log abutting said reflective surface and having a longitudinal axis substantially transverse to the plane of said reflective surface.
