Rules For Connector Pipe Installation
1. Crimped end of the pipe must be installed toward
the heater. The pipe should slide inside the flue
collar. The pipe should be firmly attached to the
flue collar with 3 screws and sealed with furnace
cement.
2. Slope any horizontal pipe upward toward the
chimney at least 1/4 " inch for each foot of
horizontal run.
3. You must have at least 18" inches clearance
between any horizontal piping and the ceiling.
4. The pipe cannot extend into the chimney flue.
(Fig. 8)
5. Seal each connector pipe joint with furnace
cement. Also seal the pipe at the chimney.
6. Use 3 sheet metal screws at each joint to make
the piping rigid.
7. It is recommended that no more than two (2)
90 degree bends be used in the stove pipe
installation as more than two (2) may decrease
the amount of draw and possibly cause smoke
spillage.
8. The chimney connector must not pass through
an attic or roof space, closet, or any concealed
space, or floor, ceiling, wall or combustible
construction.

WOODSTOVE UTILIZATION
Your heating unit was designed to burn wood only;
no other materials should be burned. Waste and
other flammable materials should not be burned in
your stove. Any type of wood may be used in your
stove, but specific varieties have better energy yields
than others. Please consult the following table in
order to make the best possible choice.

only in your wood stove. The wood should have dried
for 9 to 15 months, such that the humidity content (in
weight) is reduced below 20% of the weight of the
log. It is very important to keep in mind that even if
the wood has been cut for one, two or even more
years, it is not necessarily dry, if it has been stored in
poor conditions. Under extreme conditions it may rot
instead of drying. This point cannot be over stressed;
the vast majority of the problems related to the
operation of a wood stove is caused by the fact that
the wood used was too damp or had dried in poor
conditions. These problems can be:
- ignition problems
- creosote build-up causing chimney fires
- low energy yield
- blackened windows
- incomplete log combustion
Smaller pieces of wood will dry faster. All logs
exceeding 6" in diameter should be split. The wood
should not be stored directly on the ground. Air should
circulate through the cord. A 24" to 48" air space
should be left between each row of logs, which
should be placed in the sunniest location possible.
The upper layer of wood should be protected from
the element but not the sides.
VISIBLE SMOKE
The amount of visible smoke being produced can be
an effective method of determining how efficiently
the combustion process is taking place at the given
settings. Visible smoke consist of unburned fuel and
moisture leaving your stove. Learn to adjust the air
settings of your specific unit to produce the smallest
amount of visible smoke. Wood that has not been
seasoned properly and has a high wood moisture
content will produce excess visible smoke and burn
poorly.
EFFICIENCY
Efficiencies can be based on either the lower
heating value (LHV) or the higher heating value
(HHV) of the fuel. The lower heating value is when
water leaves the combustion process as a vapor, in
the case of wood stoves the moisture in the wood
being burned leaves the stove as a vapor. The higher
31.5
heating value is when water leaves the combustion
28.6
process completely condensed. In the case of wood
27.4
stoves this would assume the exhaust gases are room
26.8
temperature when leaving the system, and therefore
26.2
calculations using this heating value consider the
25.6
heat going up the chimney as lost energy. Therefore,
25.0
efficiency calculated using the lower heating value
23.8
of wood will be higher than efficiency calculated
22.6
using the higher heating value. In the United States all
22.1
wood stove efficiencies should be calculated using
20.1
the higher heating value.

The best way to achieve optimum efficiencies is to
learn the burn characteristic of your appliance and
