Suburban Nt Series NT22CS Parts Diagram · Exploded View › Blower Assembly

Furnace · 6 assemblies · 6 diagram sheets · 91 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban Nt Series NT22CS RV furnace: 6 assemblies (Exploded View › Blower Assembly, Replacement Furnace, Exploded View › Burner - W-alpha Valve, Exploded View › Cabinet Assembly, Exploded View › Burner - W-basotrol Valve and more) and 91 manufacturer part numbers. 19 parts are marked as superseded — the description gives the replacement number to order instead.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.
