Suburban Nt Series NT24M W-essex Valve Parts Diagram · Replacement Furnace

Furnace · 4 assemblies · 4 diagram sheets · 80 parts · by Andrew Strick, mobile RV technician

OEM exploded parts diagrams for the Suburban Nt Series NT24M W-essex Valve RV furnace: 4 assemblies (Replacement Furnace, Exploded View › Burner Assembly, Exploded View › Combustion Chamber, Exploded View › Blower Assembly) and 80 manufacturer part numbers. 19 parts are marked as superseded — the description gives the replacement number to order instead.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.
