Draft; Air Circulation System - Drolet NORDIC Owner's Manual

DRAFT

Your Drolet stove's performance will be optimized 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.

AIR CIRCULATION SYSTEM

In order to improve air circulation in the room where the wood stove is installed, certain options are available for
specific stove models.
Blower: A variable speed-control blower is available. Please note that there are two types of blowers
available, depending on the stove model you have. If the hole at the back of your stove (where the
blower needs to be hooked-up) has a round outlet, you will need blower #AC05520. If there is a
rectangular knock-off, you will need blower #AC02050.
Thermodisc: Available on most models, the thermodisc is a sensor that connects to the blower`s electrical supply
cord, and it will start the blower when the stove`s temperature reaches 120 F (49
power when the stove cools down below 100 F (37
thermodisc is included with the device.
