Suburban Nt Series NT22CDS Parts Diagram · Replacement Furnace

Furnace · 5 assemblies · 5 diagram sheets · 82 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban Nt Series NT22CDS RV furnace: 5 assemblies (Replacement Furnace, Exploded View › Blower Assembly, Exploded View › Cabinet & Vent Assembly, Exploded View › Burner Assembly, Exploded View › Combustion Chamber) and 82 manufacturer part numbers. 21 parts are marked as superseded — the description gives the replacement number to order instead.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.
