Please Read: Double Wall Stove Pipe Increaser & Reducer Tips

• The inside crimp (Crimp) is supposed to face towards the wood stove (or furnace) – this allows potential creosote to remain inside the smoke pipe as it leaks down.  Sometimes customers reverse the crimps because of smoke flow (this is not technically correct).
• An increaser (or reducer) sometimes does not fit directly on a stove collar or existing chimney connection.  You may require a small length and / or a stove adapter in between.
