This adapter increases the air intake on the back of the vent collar plate from its stock 2 in. opening to a standard 3 in. size, helping maintain correct combustion airflow. The Enviro E20/Sonnet 2 in. to 3 in. Air Intake Adapter (part 50-1499) is the replacement part for the Enviro E20 and Enviro Sonnet.

Fit

• Fits the Enviro E20, where the air intake sits on the angled back of the vent collar plate.
• Also fits the Enviro Sonnet.
• Included with the unit on both the E20 and the Sonnet, so this listing covers it as a standalone replacement part.

When to replace it

If this adapter is missing, damaged, or was never retained from the original unit, replacing it restores the intake to its proper 3 in. size for correct appliance operation.

Installation

Let the appliance cool completely before removing or installing this part.
