DRAFT
Your E.P.A Drolet stove’s performance will be optimised if it is installed with a chimney (flue)
system that provides an adequate draft. The draft is the force that moves air from the appliance up
through the chimney and is predominantly affected by the height and diameter of the chimney, as
well as the stack temperatures of the stove. If you test the draft using a pressure gauge, the
reading should be between .05 - .07 inches of water column (w.c.) at a medium-high fire. A draft
measure of less than .03" w.c. will cause operational difficulties while too much draft (greater than
.10" w.c.) will result in over-firing of the stove. This can result in excessive operating temperatures.
In this case, the installation of elbows totaling no more than 180° (ex.: 2 x 30° elbows, 2 x 45°
elbows or 2 x 90° elbows) can be installed to help reduce excessive draft. If the addition of elbows
is not sufficient, a manual damper can be installed in the vertical flue pipe.
