If smoke ever leaks constantly into the room stop using the fire immediately, shut down all vents on the stove, open
windows and exit the room. Do not use the stove until a local expert has established the problem.
Common causes:
a.
Insufficient air supply into the room
–
do you have an air brick of sufficient size to feed the stove with air?
b.
Blocked chimney
–
have the chimney swept and checked by a registered chimney sweep.
c.
Insufficient chimney draught
–
can be due to a variety of reasons
–
please refer to previous text under
“Poor draught
and chimney strength”
d.
Rapid condensation of the gases
- causing them to slow down and back up in the chimney
–
this can be due to too
broad a chimney/flue, relative to the size of the appliance or the flue not being adequately insulated. You may need a
flue liner and/or insulation in the chimney.
4. Glass gets dirty quickly
Common causes:
a.
Top vents not open
–
Your stove has a top vent this controls the Airwash system
–
the top vent needs to be
constantly open adequately to ensure enough air is coming into the stove. No Airwash will work fully when the stove is
burning very slowly (slumbering).
b.
Primary Vent left open
–
Primary vent when left open will interfere with the operation of the Secondary (Airwash),
causing blackening of the window. Always shut Primary once fire is established, and only ever open as much as
necessary to get the fire going
or to give a short ‘boost’ to new wood when refuelling.
c.
Poor fuel
–
wet wood or softwood (e.g. pine) will produce a lot of tar, creosote and soot, dirtying the glass and
eventually blocking the flue.
d.
Insufficient chimney draught
–
see previous note
under “Poor draught and chimney strength”.
e.
Baffle plates incorrectly fitted
–
see previous diagram for correct positioning of baffles.
f.
Fuel loaded to close to window
–
The wood needs a good clear distance away from the glass
–
otherwise it will
produce thick black marks on the glass and interfere with the Airwash airflow.
5. Not enough heat being produced
Common causes:
a.
Poor quality fuel
–
logs should be dry well seasoned hardwood.
b.
Poor draught and chimney strength
–
see previous notes.
c.
Excessive draught
–
too much heat being lost up the chimney
–
try a damper in the flue.
d.
Insufficient air supply
- Check air supply is sufficient / vents on stove are clear. Does the room have a vent?
e.
Not enough fuel being burned
–
the rated output of your stove is based on burning beech wood (typical of most
hardwoods), refuelling once per hour. 1kg of this wood has approximately 4-5 kw hours of energy.
