Disposal of Ashes
Ashes should be placed in a metal container with a tight
fitting lid. The closed container of ashes should be placed
on a non-combustible floor or on the ground, well away
from all combustible materials, pending final disposal. If the
ashes are disposed of by burial in soil or otherwise locally
dispersed, they should be retained in the closed container
until all cinders have thoroughly cooled. Other waste should
not be placed in this container!
Creosote
Formation and Need for Removal
When wood is burned slowly, it produces tar and other
organic vapours, which combine with expelled moisture
to form creosote. The creosote vapours condense in the
relatively cool chimney flue of a slow burning fire. As a
result, creosote residue accumulates on the flue lining.
When ignited, this creosote makes an extremely hot fire.
The chimney connector and chimney should be inspected
at least once every two months during the heating season
to determine if a creosote buildup has occurred. If creosote
has accumulated, it should be removed to reduce the risk
of a chimney fire.
1. Highest smoke densities occur when a large amount of
wood is added to a bed of hot coals and the air inlet is
closed. The heated wood generates smoke, but without
ample air, the smoke cannot burn. Smoke-free, clean
burning requires small fuel loads, two or three logs at a
time or 1/4 to 1/2 of a fuel load and leaving the air inlet
relatively wide open, especially during the first 10 to 30
minutes after each loading, when most of the smoke
generating reactions are occurring. After 30 minutes or
so, the air inlet can be turned down substantially without
excessive smoke generation. Wood coals create very
little creosote-producing smoke.
2. The cooler the surface over which wood smoke is
passing, the more creosote will be condensed. Wet or
green wood contributes significantly to creosote forma-
tion as the excess moisture that is boiled off cools the
fire, making it difficult for the tars and gasses to ignite,
thus creating dense smoke and poor combustion. This
moisture-laden smoke cools the chimney, compounding
the problem by offering the smoke the ideal place to
condense.
In summary, a certain amount of creosote is inevitable and
must be lived with. Regular inspection and cleaning is the
solution. The use of dry, seasoned wood and ample com-
bustion air will help to minimize the buildup.
5) To achieve maximum firing rate, set control to "H" (high).
Do not use this setting other than for starting or preheat-
ing fresh fuel loads.
DO NOT OVERFIRE THIS HEATER: Attempts to achieve
heat output rates that exceed heater design specifica-
tions can result in permanent damage to the heater
and chimney.
WARNING: No alteration or modification of the combus-
tion air control assembly is permitted. Any tampering
will void warranty and could be very hazardous.
More Wood, More Heat
Seasoned wood has approximately 7500 BTU’s per pound.
If you put 10 pounds of wood in your stove for an eight hour
burn the wood will be producing 9375 BTU’s per hour. (7500
BTU x 10 lbs / 8 hrs. = 9375 BTU’s per hr.). If you put 20
lbs of wood in your stove for an eight hour burn you will get
18,750 BTU’s per hr. (7500 BTU x 20 lbs / 8 hrs. = 18,750
BTU’s per hr.). This is only an example and is based on
100% efficiency. In reality, your stove should perform in
the 70% efficiency range.
Experience will give you the right settings for proper combus-
tion and efficient burning. Remember the air inlet setting is
affected by variables such as type of wood, outside tempera-
ture, chimney size and weather conditions. With practice,
you will become proficient in operating your heater and will
obtain the performance for which it was designed.
Proper Draft
1) Draft is the force which moves air from the appliance
up through the chimney. The amount of draft in your
chimney depends on the length of the chimney, local
geography, nearby obstructions and other factors.
2) Too much draft may cause excessive temperatures in
the appliance. An uncontrollable burn or a glowing red
stove part or chimney indicates excessive draft.
3) Inadequate draft may cause backpuffing into the room
and plugging of the chimney. Smoke leaking into the
room through appliance and chimney connector joints
indicates inadequate draft.
Ash Removal
Whenever ashes get 3 to 4 inches deep in your firebox,
and when fire has burned down and cooled, remove excess
ashes. Leave an ash bed approximately 1 inch deep on the
firebox bottom to help maintain a hot charcoal bed.
