Enviro M55 Exhaust Starter Tube w/Gasket - 4 in. (50-2043)

Soot around the exhaust collar, a faint burning smell near the back of the stove, or visible gaps at the venting connection often point to a worn starter tube gasket. The Enviro M55 Exhaust Starter Tube w/Gasket (part 50-2043) replaces the worn exhaust connection component on compatible Enviro pellet stoves.

Purpose

This is the point where the exhaust venting attaches to the M55 pellet stove, directing combustion byproducts outside the home through a connected venting system.

Key Benefits

• Restores a tight seal at the exhaust connection point
• New factory-sealed gasket helps prevent leaks that develop as the original ages
• Direct-fit replacement for the M55 exhaust starter tube assembly
• Supports consistent, long-term venting performance

Specifications

• 4 in. exhaust starter tube with attached gasket
• Enviro part number 50-2043 (also listed as 502043)

Other Notes

A worn or cracked gasket at this joint can allow exhaust gases to escape rather than vent outdoors, so inspect the seal closely whenever the stove is serviced and replace it at the first sign of hardening or gaps.

While accessing this connection, it's worth inspecting nearby door and access panel gaskets for wear, since these seals tend to age at similar rates.
