Värmebaronen Vedolux -350, -450 and -650
In a well-swept boiler, less heat
accompanies the flue gases out. Check
the flue gas temperature. Sweeping to
keep costs down is a good idea when the
temperature has risen by approximately
80°F compared to a well-swept boiler.
The Swedish Rescue Services Act specifies how
frequently the system must be swept and the time
interval between sweeping. When the system is swept
by a chimney sweep, all flue gas ducts are swept.
Sweeping to keep costs down should take place at
shorter intervals. It is done by cleaning the flues with
a flue brush.
Tar that forms on the walls of the combustion
chamber does not normally need to be removed.
A good aid for emptying the boiler of ash is an ash
trap, which is connected to a vacuum cleaner.
Sweeping
RISK OF BURN INJURIES!
Before sweeping:
- Let the boiler cool down.
- No fire or embers in the boiler.
Sweeping is carried out from the front of the boiler.
• Press
and open the hatches.
• Fold down and insert the soot hatch so it covers the
opening of the bypass damper.
• Pull out the turbulators.
Check the turbulators each time you sweep.
Damaged turbulators must be replaced.
• Sweep the flues with the flue brush.
Be careful when sweeping the upper flues so that
the flue brush does not pass through the protective
grating and damage the fan. The flue brush must
not be inserted further in than the end of the flue.
You will know it is there because less force is
required to move it.
• Refit the turbulators.
• Remove and empty the soot hatch and remove any
soot that has been deposited on the bypass damper’s
sealing surfaces. Refit and close the soot hatch.
• Pull out the bypass plate and empty it in the
combustion chamber. Refit it.
• Leave an ash layer of a few centimetres to protect
the ceramics. Pieces of charred wood can remain.
Rake surplus ash down through the grate.
• Rake away the ash in the ceramic duct. Leave a
layer of a few centimetres here too.
• Check, after lifting out the grate, that no ash or
pieces of charred wood are blocking the secondary
air ducts in the ceramics.
• Clean around and in front of the lower ceramics.
• Close the hatches.
The ash may contain residual embers for
a long time after firing. Therefore, keep it
in a non-combustible container with a lid.
Place the container on a non-combustible
base.
Sweeping the chimney
After sweeping the chimney, loosen the wing nuts on
the front of the flue pipe and remove the cover so that
soot and ash can be removed.
Remove any ash that has fallen down on the fan and
in the collection chamber before the boiler is started
again.
Cleaning the fan
When required, remove the fan and clean it. Handle
it with care.
• Detach the fan’s electrical connector and loosen
the nuts that hold the fan in place.
• Clean the fan blades carefully with a brush.
• Refit the fan. Do not forget to connect the power cable.
