The stove pipe for a sauna stove is located on the OUTSIDE of the flue, which avoids
water getting into the stove when pouring water onto the rocks!
Stove pipe for a room heater or wood stove is located on the INSIDE of the flue, allowing
creosote to flow downward.
Stove pipe for a sauna stove should be standard black pipe. To flatten the “Pittsburg
Seam” on the first section, join the tube at the seam, lay it flat on a hard surface and using
a hammer, pound the seam about 1 ½” up from the crimped end. This will still be a tight
fit, but will allow the pipe to fit OVER the flue.
If you wish to use insulated pipe for a sauna stove, the first course must be standard black
pipe. Insulated pipe will not fit on the outside of the flue.
Wood stoves or room heaters may use insulated pipe OR standard black pipe.
At the ceiling for either stoves remember to use insulated pipe fittings!
