Venting - What's Involved?

Stoves, fireplaces, and fireplace inserts need to be vented to the outdoors, with the exception of electric models. There are several ways venting is routed and installed, depending on the type of hearth product and the fuel it burns. Here’s a quick overview:

    • Direct Vent Gas Fireplaces – most are vented to the outdoors horizontally directly through the wall, but they can also be routed vertically through the roof. 
    • Wood Fireplaces and Stoves – venting must be terminated to the outdoors vertically. It involves installing a vent pipe or chimney that runs from the unit up through the ceiling and rafters to the roof line.
    • Pellet Stoves – most are vented horizontally directly through the wall to the outdoors, similar to direct vent gas fireplaces. Pellet stove venting consists of a pressurized hybrid system with a stainless steel inner wall and gaskets that seal tightly. 
    • Fireplace Inserts – most are vented vertically through the roof via the existing chimney. A stainless steel flexible single liner (vent pipe) is routed up the chimney, terminating above the roof line. 
    • Electric Fireplaces – no venting is required.
