The Suburban SF-30 30,000 BTU ducted LP furnace uses three exploded parts illustrations. Original model callouts are grouped into cabinet components, burner and ignition parts, and motor, circulating-air and exhaust assemblies.
This reference retains the original drawing positions and historical service entries. Manufacturer numbers only link to active products where the part and model have a supported match. Old or disputed numbers, serial-restricted parts and uncertain substitutions remain plain text.
