Flue Pipe + Chimney

Your Greenstone Masonry Heater will require a flue pipe to vent gases to the outside of the home. The flue pipe can exit out the top or through the back wall of the heater. The above pictures show three options for the flue pipe. You can use an exposed black stove pipe or an exposed stainless steel chimney pipe. You can also hide it in a wrap of soapstone. Side active chimneys are optional with most of our heaters and add additional thermal mass and efficiency to your masonry heater.

All of our units use an 8-inch interior diameter pipe. You should have no more than a single offset, utilizing elbows of no greater than 30 degrees. Double-wall black stove pipe requires a 6″ clearance to combustible materials. Insulated, double-wall chimney pipe requires a 2″ clearance to combustibles. To maintain consistent flue pipe draw, it is best to route the flue pipe directly up. Position it above your masonry heater. Furthermore, keep it in a conditioned space as long as possible. All of our masonry heaters require a minimum of 17 linear feet of flue pipe.

We specify Class-A, Double-Wall Insulated ICC or Selkirk Metalbest chimney pipe. The link below will provide essential installation instructions.
