Replacement is recommended when a liner is structurally failed, wrong for the fuel, undersized, oversized, severely corroded or impossible to repair responsibly. The work begins with appliance data, flue measurements, access planning and confirmation of the complete connection and termination system.

Service questions

Details worth understanding.

Final specifications depend on the inspected conditions, appliance listing, selected manufacturer and applicable local requirements.

Must the old liner always be removed?+

Not always. The route, flue dimensions and compatibility determine whether removal, partial removal or another listed design is appropriate.

Can one liner serve multiple appliances?+

Only when the common-vent design is permitted and correctly sized for the exact appliances and fuel. Separate systems may be required.
