When a gas insert runs with an uneven flame or the burner won't reach proper output, a worn or incorrect main burner orifice is often the cause. The Enviro EX32 Burner Orifice #37 Bullet Tip (part 50-4236) is a genuine Enviro natural gas main burner orifice sized for the Enviro EX32 gas insert, and it controls how much gas reaches the main burner.

When to replace it

If the flame looks weak, uneven, or the burner won't meet its rated output, the orifice may be worn or the wrong size for the gas type in use. Gas burner issues are worth addressing promptly rather than working around them.
