This HF-8012D electronic-ignition furnace guide separates the original reference into gas and burner, air-moving, electrical, and cabinet/vent sections. The single exploded drawing is kept above the numbered tables, so each group can be read on a phone without a sideways-scrolling parts table.
Match each drawing callout to the part number and description, including any discontinued-part or supersession notes. Select a linked number for product details and check the furnace model and serial range before ordering.
