3.4 TROUBLESHOOTING
THE VARIOUS REASONS THE STOVE MIGHT NOT
WORK PROPERLY
THE FLUE PIPE
•
Too short.
The flue pipe stretches from the connection with
the stove to the base of the chimney pot. If the flue pipe is too
short, increasing its internal width will never compensate for
the reduction in height as that will only increase heat
dispersion, lower the temperature of the gases and potentially
compromise flue draught pressure. You are better advised to
use a flue pipe of the correct width and increase its height by
1 or 2 metres to ensure decent flue draught pressure.
•
Too long.
This doesn’t generally affect flue draught pressure;
however the flue pipe should be well INSULATED to minimize
heat dispersion.
•
Too wide.
A flue pipe that is too wide will have a
proportionally larger surface area that will encourage the
gases to cool down and therefore compromise flue draught
pressure. One option is to put a stainless steel pipe of
suitable width inside the existing flue pipe and, after
connecting it to the stove, fill the gap between the two pipes
with heat-resistant granular insulation material.
•
Too narrow.
IToo narrow. In this case you will not be able to
exploit the stove’s potential. We can only suggest that you
reconstruct the flue pipe according to the required
specifications.
•
Tight sections.
Changes in the pipe’s width will cause a loss
of flue draught pressure, slowing down and potentially
preventing the gases from leaving the flue.
•
Too many bends.
Bends cause a loss of flue draught
pressure, preventing the gases from leaving the flue. For each
bend you need to increase the height of the flue pipe by 50
centimetres so as to ensure optimal flue draught pressure.
•
Excessive deviations.
Deviations affect the discharge of
gases and should generally be avoided.
The slits are wide enough to let through the ash and any
dead embers; while the walls of the slits are conical so as to
not block the flow of air.
THE GRILL MUST BE POSITIONED WITH THE NARROW
SIDE OF ITS SLITS FACING UPWARDS.
INTERNAL ASH DRAWER
The ash drawer must be emptied on a regular basis to
prevent the iron grill from overheating.
THERE MAY STILL BE SOME GLOWING EMBERS
IN WITH THE ASH.
PROBLEM
POSSIBLE CAUSE
The stove does not work
It is not connected properly to the flue
The flue pipe does not conform
Other appliances are connected to the flue pipe
The hearth grill is the wrong way round
The hearth grill is blocked with ash
Smoke comes out of the plate
No flue draught pressure
It is not connected properly to the flue
The starter and/or primary air valve is closed
The plate’s seals have come loose or are broken
Condensation in the hearth
The wood is damp or not properly seasoned
The flue is too wide
Poor flue draught pressure
The fire lights with difficulty
The starter is not fully open
The flue is cold (due to a long period of inactivity)
The oven does not get sufficiently hot
Poor or insufficient flue draught pressure
The internal pipes are clogged
The starter is open
Excessive flue draught pressure
