Built for Enviro E44 gas inserts, including the E44I-S2, E44I-S3 and E44ID, this tube burner (part 50-3654) replaces the worn or damaged burner in these compatible Enviro appliances. The 50-3654 is a genuine Enviro part manufactured to the specifications of the original equipment it replaces.

Purpose

The burner distributes gas to the flame ports and supports the combustion pattern the insert was designed around, which affects both flame appearance and heat output.

Key Benefits

• Supports correct, even combustion across the burner ports
• Direct-fit for listed E44 models — no modification needed
• Genuine Enviro part built to original specifications
• Helps restore consistent flame shape and factory heat output

Other Notes

Because this is a gas component, any burner issue — irregular flame, poor ignition, or uneven combustion — should be looked at promptly rather than worked around. Installation and gas connection work should be handled by a licensed gas technician in accordance with local codes.

When replacing this burner, it's worth having a technician inspect related components such as the gas valve, pilot assembly, and burner seal, since wear in these parts often shows up around the same time.
