180224 Suburban Bruner Orifice NT-16S/SE NT-16SQ/SEQ #56

The Suburban 180224 Burner Orifice meters the precise LP gas flow into the burner tube on NT‑16‑series furnaces. This #56‑sized orifice is calibrated for the BTU rating of the NT‑16 platform, ensuring proper ignition, stable flame shape, and clean combustion. Using the correct orifice is essential for maintaining furnace efficiency and preventing soot, yellow flames, or ignition failures.

This is the OEM replacement for all NT‑16 burner assemblies, including both standard and quick‑connect SQ/SEQ variants.
