Abstract
Abstract A base assembly for a downflow mobile home furnace provides an upper compartment for an air cooling coil, and a smaller base compartment, connecting duct means extending through the lower compartment and providing a perimetric space therearound. Make-up air chute means is positionable to extend downwardly from a selected side of the perimetric space, and the casing around the space provides openings for the make-up air to exit and flow upwardly around the sides of the casing as installed in an alcove or closet. Preferably, the assembly also includes a floor plate slidably receiving the casing and extending inwardly to provide the air chute mounting means on a plurality of sides thereof. The refrigerant tube means can extend through the base compartment selectively along any side thereof, the make-up air duct means terminating at the bottom of the base compartment, thereby permitting the refrigerant tubes to run over the top of the air chute if necessary.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
237 words
In a mobile home furnace having an exterior casing with vertically extending walls, the combination comprising: a perimetric floor plate for placement on a floor for slidably receiving said furnace casing and defining a central opening; platform means secured to said furnace casing and spaced above said floor plate when said furnace is in assembled relation therewith, said platform means extending inwardly of said casing and dividing the lower portion of said casing into an upper air cooling compartment and a lower compartment; a connecting duct connected to said platform means and extending downwardly thereof for communicating the interior of said upper air compartment with a distribution duct in said home beneath said Furnace, said connecting duct spaced inwardly of the sides of said casing to enclose said lower compartment and to provide an inner wall for a perimetric make-up air space in combination with said floor plate, said platform means and the casing of said furnace, said furnace defining a plurality of apertures communicating said perimetric make-up air space with the interior of an alcove receiving said furnace; and chute means attachable to said floor plate for extending through the floor of said mobile home and communicating said make-up air space with the outside of said mobile home for passing outside air to said make-up air space, said perimetric make-up air space being free for routing conduits or refrigerant lines to any side of said furnace.
Claim 2
Dependent Claim
237 words
In a mobile home furnace having an exterior casing with vertically extending walls, the combination comprising: a perimetric floor plate for placement on a floor for slidably receiving said furnace casing and defining a central opening; platform means secured to said furnace casing and spaced above said floor plate when said furnace is in assembled relation therewith, said platform means extending inwardly of said casing and dividing the lower portion of said casing into an upper air cooling compartment and a lower compartment; a connecting duct connected to said platform means and extending downwardly thereof for communicating the interior of said upper air compartment with a distribution duct in said home beneath said Furnace, said connecting duct spaced inwardly of the sides of said casing to enclose said lower compartment and to provide an inner wall for a perimetric make-up air space in combination with said floor plate, said platform means and the casing of said furnace, said furnace defining a plurality of apertures communicating said perimetric make-up air space with the interior of an alcove receiving said furnace; and chute means attachable to said floor plate for extending through the floor of said mobile home and communicating said make-up air space with the outside of said mobile home for passing outside air to said make-up air space, said perimetric make-up air space being free for routing conduits or refrigerant lines to any side of said furnace.
Claim 3
Dependent Claim
57 words
The system of claim 1 wherein said upper compartment is provided with an openable panel for access, and said casing further includes a front louvred panel spaced outwardly from said closure panel, said perimetric air space communicating through the space between said closure panel and said louvred panel with the alcove in which said furnace is installed.
Claim 4
Dependent Claim
73 words
The system of claim 1 wherein said floor plate includes a plurality of separatable flange sections extending about the interior thereof, each adapted, when separated, to provide a receptacle for receiving said make-up air chute, whereby said make-up air chute may be selectively positioned at the plurality of positions, at least one of which is adjacent each side of said casing while maintaining said perimetric make-up air space free for routing lines therethrough.
Claim 5
Dependent Claim
38 words
The system of claim 3 in which said chute means in its normal use position communicates with the bottom of the adjacent portion of said perimetric space leaving the adjacent space portion open for routing refrigerant tube lines.
Claim 6
Dependent Claim
48 words
The system of claim 1 wherein said floor plate means includes a flat peripheral portion adapted to slidably receive a furnace during installation and further includes upturned side flanges at each side and the rear for registering the bottom edge of the casing of said furnace during installation.
Claim 7
Dependent Claim
216 words
In a mobile home furnace having a casing with vertically extending walls, the combination comprising: a perimetric floor plate adapted for placement on the floor to slidably receive the casing of said furnace during installation, said floor plate including a flat peripheral inwardly extending flange to define a central opening and a plurality of removable flange portions, at least one on each side of said floor plate adjacent said opening, each flange portion providing a receptacle upon removal; an air chute including means for attachment to a receptacle of said floor plate with the upper end thereof at the level of said floor plate to communicate the perimetric space above said floor plate with the exterior of said mobile home; platform means attached to the interior of said casing to define the upper portion of said perimetric air space above said floor plate; and a connector chute extending downwardly from said platform means through said central opening of said floor plate to provide the inner walls of said perimetric air space; said casing of said furnace providing the outer walls for at least a portion of said perimetric make-up air space above said floor plate and being provided with outlet apertures to communicate said perimetric air space with an alcove in which said furnace is installed.
Claim 8
Dependent Claim
216 words
In a mobile home furnace having a casing with vertically extending walls, the combination comprising: a perimetric floor plate adapted for placement on the floor to slidably receive the casing of said furnace during installation, said floor plate including a flat peripheral inwardly extending flange to define a central opening and a plurality of removable flange portions, at least one on each side of said floor plate adjacent said opening, each flange portion providing a receptacle upon removal; an air chute including means for attachment to a receptacle of said floor plate with the upper end thereof at the level of said floor plate to communicate the perimetric space above said floor plate with the exterior of said mobile home; platform means attached to the interior of said casing to define the upper portion of said perimetric air space above said floor plate; and a connector chute extending downwardly from said platform means through said central opening of said floor plate to provide the inner walls of said perimetric air space; said casing of said furnace providing the outer walls for at least a portion of said perimetric make-up air space above said floor plate and being provided with outlet apertures to communicate said perimetric air space with an alcove in which said furnace is installed.
