Description
The Cozy Heaters 84166 Blocked Flue Switch is a genuine OEM safety component engineered for use in Cozy wall furnace systems. Designed to continuously monitor exhaust flow and venting conditions, this switch provides a critical layer of protection for both the heating system and the occupants of the home.
How It Works
When the switch detects a restricted or blocked flue condition — meaning combustion gases are not safely exiting the system — it automatically shuts down the furnace. This prevents the dangerous buildup of harmful gases, including carbon monoxide, inside the living space. Once tripped, the switch requires a manual reset after the underlying venting issue has been identified and corrected, ensuring the system is not restarted until it is safe to do so.
