Claim 9

In a downflow mobile home furnace having a vertically extending exterior casing of rectilinear cross section, the lower portion of which encloses a downflow air space, the base assembly combination comprising: a. platform support means mounted within said casing lower portion and dividing said downflow air space into an upper compartment and a base compartment, said upper compartment being of large size relative to said base compartment for receiving air cooling coil means; b. connecting duct means extending downwardly from said upper compartment through the central portion of said base compartment for communicating with the distribution duct system of the mobile home, the sides of said connecting duct means being spaced inwardly from the sides of said casing to provide a perimetric space therearound; c. make-up air chute means selectively positionable in a plurality of positions to extend downwardly from a selected side of said perimetric space to receive outside air from beneath the floor of the mobile home, said chute in its normal position communicating with the bottom of the adjacent portions of said perimetric space, leaving the perimetric space open for receiving refrigerant tube means; d. air outlet opening means provided in the portions of said casing walls enclosing said perimetric space and arranged to communicate with the lower portion of a closet or alcove in which said furnace is installed; and e. air cooling coil means installed in said upper compartment and refrigerant tube means arranged to extend through said perimetric space of said base compartment and upwardly therefrom for connection to said coil means.

Claim 10

The base assembly of claim 7 in which said upper compartment is provided with removable closure panel means on its front side, and said platform support means provides slidable track means extending inwardly from said front side and arranged to provide for the slidable insertion and removal of said air cooling coil means.

Claim 11

In a mobile home furnace and air cooling system having a rectilinear casing with vertically extending walls, the combination comprising: platform means secured to said casing adjacent the bottom thereof and extending perimetrically thereabout; the lower portion of said casing providing an air cooling compartment with an open front side; air cooling coil means including refrigerant lines slidably received in said compartment and supported by said platform means; closure panel means attachable to said casing for closing said compartment, said refrigerant lines extending through said closure panel means; a connecting duct communicating the interior of said compartment with a distribution duct in said home beneath said furnace and spaced inwardly of the sides of said casing to provide a perimetric make-up air space; a perimetric floor plate disposed beneath said casing and partially defining said perimetric make-up air space; and chute means attachable to said floor plate and 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 and serving as a conduit to the outside for said refrigerant lines.
