This blower is the replacement for the Enviro G39, G42 and G50 Sit Proflame 2 gas fireplaces. The Enviro Blower Replacement (part 50-3577) replaces the worn room air blower in these compatible Enviro gas fireplaces, moving room air across the firebox and back out into the space.

Key Benefits

• Restores factory-level heat circulation into the room
• Improves overall heating efficiency of the fireplace
• Genuine Enviro part, shipped new in original packaging
• Direct-fit for listed models — no modification needed

Purpose

The blower circulates room air around the fireplace body and projects it back into the room, optimizing the heat output of the unit rather than letting warmth stay trapped near the appliance.

Specifications

• Enviro part number 50-3577 (also listed as 503577)

Other Notes

A blower that is worn or seized tends to leave heat concentrated near the fireplace instead of pushing it evenly through the room, so uneven room temperatures are often a sign it's time to check this part. Cross-reference the part number and photos against your unit before ordering, since blower assemblies generally cannot be returned once installed.

While replacing the blower, it's worth inspecting related electrical components such as the wire harness, speed control switch, and blower motor mount for wear or corrosion.
