Weak flame, uneven burner performance, or a yellow-tipped flame on the EX32 often points to a worn or incorrect main burner orifice restricting proper gas flow. The Enviro EX32 Burner Orifice #37 Long (50-4558) is the genuine replacement main burner orifice for the Enviro EX32, restoring the correct natural gas flow needed for efficient, steady combustion.

When to replace it

If the burner struggles to reach full flame, burns unevenly, or the orifice shows wear or damage, it's time to replace it rather than risk ongoing gas valve or burner problems. Gas-related performance issues on the EX32 should be corrected promptly rather than worked around.
