Blower deck for upflow or downflow furnace

An upflow or downflow furnace comprising:

• a housing;
• a heat exchanger section in the housing, the heat exchanger section including at least one heat exchanger;
• a blower section in the housing, the blower section including a blower for moving air through the heat exchanger section;
• a horizontally arranged blower deck in the housing having an upward side and a downward side, the blower deck separating the blower section and the heat exchanger section, the blower deck including an aperture and a plurality of tabs, in proximity to the aperture, for either
• mounting the blower to the downward side of the blower deck for an upflow furnace configuration wherein air is blown upwardly across the heat exchanger section, the heat exchanger section being located on the upward side of the blower deck or
• mounting the blower to the upward side of the blower deck for a downflow furnace configuration wherein air is blown downwardly across the heat exchanger section, the heat exchanger section being located on the downward side of the blower deck;
• the blower including a flange adapted to engage the plurality of tabs;
• wherein the plurality of tabs are open at a first end of the aperture to allow the flange to slide into engagement with the tabs;
• and
• wherein the plurality of tabs includes a first set of tabs raised from the plane of the blower deck, a second set of tabs lowered from the plane of the blower deck, and a third set of tabs located in proximity to a second end of the aperture to act as a stop for the blower.
