Chimney Extension - Insulated 8" x 24". This product meets specifications for all HE, GH, and BHS model furnaces. (NOTE: This 8" size will NOT fit GX model furnaces.)

This Chimney Extension also meets specifications for any indoor wood stove or other chimney extention needed that requires an 8" diameter. 

Note that these products also feature the Selkirk "Snap Lok" at both ends (female at bottom, male at top).

Also NOTE: A "Chimney Extension Adapter - 8"" is required to attach this extension to any HE, GH, or BHS model furnace.

All Chimney extensions are shown by their INSIDE diameter and length. The outside diameter is always 2 inches wider. Accordingly, this product has an OD of 10".

NEVER use an uninsulated chimney extension. Outdoor wood boiler exhaust contains high amounts of steam from the wood fuel, and this steam must exit the furnace without condensing on the chimney wall. If the chimney wall is uninsulated, this steam will condense on the chimney wall, and highly acidic moisture will ruin most boilers in less than a few months.

Outdoor Boiler experts agree that only triple wall insulated chimney extensions should be used. Our products have a perfect safety record of protecting outdoor wood boilers and providing years of service.
