Claims18
A clamshell heating chamber for a gas furnace, comprising:
- a male half;
- a female half configured to receive the male half, the male half and the female half forming a clamshell heating chamber when joined together;
- a chamber path passing through the clamshell heating chamber, the chamber path comprising:
- an inlet coupled to the chamber path for receiving combustion air into the chamber path;
- an outlet coupled to the chamber path for exhausting the combustion air from the chamber path;
- one fold positioned between the inlet and the outlet;
- and
- wherein the chamber path divides into a plurality of paths between the inlet and the one fold;
- and
- a truncated corner located adjacent a curve located at a back end of the chamber path, the truncated corner located diagonally opposite from a combustion location within the gas furnace,
