The exhaust blower on an Enviro pellet stove depends on a steady vacuum signal to prove it's running correctly, and that signal travels through this red silicone hose. The Enviro Silicone Hose (part EF-018) replaces the worn or cracked hose connecting the combustion blower to the pressure switch.

Purpose

This hose carries the vacuum reading from the combustion blower to the pressure switch, allowing the stove's control board to confirm the exhaust blower is operating properly before permitting normal operation.

Key Benefits

• Maintains an accurate vacuum signal so the pressure switch reads correctly
• Supports proper combustion airflow and safe exhaust blower operation
• Direct-fit replacement for the original Enviro hose
• Silicone construction resists heat and cracking better than a brittle original hose

Specifications

• Color: red
• Material: silicone

Other Notes

Inspect the hose ends and clamps for cracking or a loose fit when replacing it, since a poor seal can throw off the pressure switch reading even with a new hose installed.

This part fits 15 compatible models on record. When replacing this hose, it's worth also inspecting the pressure switch and combustion blower gasket, since all three work together to regulate exhaust airflow.
