smoking problems from appliances with exposed interior single wall flue
Great DIY project. Easily
installs by cutting a rectangular 8 5/8” x 3 1/8” hole in the single
wall flue pipe from the stove.
Vertical mounting, you need at
least 12 to 24” clearance above the stove. A closer mounting may be
possible with some form of heat shield to deflect rising heat from
“cooking” the fan controls. The AD-1 has a heat-treated housing that
allows it to withstand pipe temperatures up to 700 degrees and even
though the unit gets HOT from the high pipe temps the ambient room air
around the controls should not exceed 104 degrees.
On a horizontal pipe
installation the fan must be in attached to the underside of the pipe
and concern be placed on its distance from a combustible wall surface.
This installation may also keep the unit cooler as it will be further
from the heat source.
The fan is only pre wired to the
speed control…. There is no “plug-in” cord off the control box, but the
unit only draws .8 amps, so a wired plug can be attached to use a close
wall outlet. A conduit pipe should be part of the electrical
installation, mostly to protect the cord from touching and accidentally
melting on the hot flue pipes.
After installation, a turn on
the variable speed switch allows smoke free loading and tending of your
AD-1 Auto-Draft Draft Inducer Installation
manufacturers produce a wide variety of draft inducers for gas and oil
appliances. Tjernlund, a leading and innovative presence in this
field, has introduced a draft inducer for wood and coal applications.
Tjernlund has taken their model D-3 and modified it for the much needed
task of draft assisting the common free-standing wood stove.
The D-3, DJ-3 and other models,
even similar from other manufacturers, are not recommended for a solid
The AD-1 can be identified by its
BLACK heat treated paint finish and adjustable speed control.
Right now, this is the only
manufacturer recommended draft inducer for this application.
.... and the most economical compared to duplicating it with standard
similar looking fan models and additional controls.
