180214 Suburban Bruner Orifice #52

NT-30 M S SP SF-30 30F P-30S NT-30K #52

OEM #52 LP Gas Orifice for Mid‑Size Suburban Furnaces

The Suburban 180214 Burner Orifice meters the precise LP gas flow into the burner tube on NT‑30, SF‑30, and P‑30S furnace platforms. Sized at #52, this orifice is calibrated for the BTU output of the 30k BTU class Suburban furnaces, ensuring proper ignition, stable flame shape, and clean combustion. Using the correct orifice is essential for maintaining furnace efficiency and preventing yellow flames, soot buildup, or ignition failures.

This is the OEM replacement for the NT‑30 M/S/SP series, SF‑30 and SF‑30F furnaces, and the P‑30S platform.
