DuraVent DuraLiner Flat Stove Connector: a straight connection above your fireplace insert
The DuraVent DuraLiner Flat Stove Connector is a single wall fitting that joins a fireplace insert to the liner inside the chimney. It sits on the insert’s flue outlet, the opening where exhaust leaves, when that outlet points straight up the chimney. The round version joins a round outlet to round liner pipe. The oval version takes a round outlet into an oval liner. The connector attaches to the insert with high temperature sealant and screws. DuraLiner is DuraVent’s factory insulated double wall pipe for relining a masonry chimney that vents a wood, pellet, coal, oil, or gas appliance. Relining means putting a new vent pipe inside the old chimney.
Choose round or oval on this page, then select a 6 inch or 8 inch size to match your connection. Oval liner can fit a chimney passage or damper opening too narrow for round pipe while carrying the same flow as the corresponding round size. The chimney’s inside shape determines which liner shape to use. Need an angled connection instead? See the DuraVent DuraLiner 30 Degree Stove Connector. The DuraVent DuraLiner Flat Stove Connector ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
