010978 Suburban Bruner Assembly 

NT-12/16/20S NT-12/20SE NT-16/20 SQ/SEQ, NT16SE (ABOVE SERIAL NO. 000303844)

Replaces 030621, 010624

The Suburban 010978 Burner Assembly is the OEM complete burner unit used across the NT‑12, NT‑16, and NT‑20 furnace platforms. It includes the burner tube, mounting bracket, and factory‑set porting that ensures correct flame geometry, stable ignition, and clean combustion. This assembly is the direct replacement for older burner units and supersedes Suburban part numbers 030621 and 010624.

Because the NT‑series shares a common burner architecture across S/SE and SQ/SEQ variants, this is one of the most widely compatible burner assemblies in the Suburban lineup.
