Suburban Nt Series NT12C Parts Diagram · Exploded View › Burner Assembly

Furnace · 3 assemblies · 6 diagram sheets · 60 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban Nt Series NT12C RV furnace: 3 assemblies (Exploded View › Burner Assembly, Exploded View › Cabinet Assembly, Exploded View › Combustion Chamber) and 60 manufacturer part numbers. 8 parts are marked as superseded — the description gives the replacement number to order instead.

The rating plate is on the furnace chassis — slide the unit's front panel off or look just inside the exterior access door. Suburban models (SF-30F, NT-34SP …) changed burners and boards over the years, so the serial number's date range matters as much as the model.
