Installation and sealing
The burner should be mounted directly on VEDEX´s pellet
burner hatch in the ashbox cutout. The fan is removed and
replaced by a cover plate. This is to prevent the motor be-
ing damaged by high temperatures. Primary and secondary
air dampers must be closed and sealed so there is no risk of
condensation or the flue gases escaping into the room. See
illustration to the right.
An installation with or without ceramics can be selected.
If you choose to retain the ceramics the hole should be
plugged with fireproof material. This is to prevent conden-
sation and overpressure in the log area.
Turbulators
All turbulators can be retained with normal chimney
draughts. With a fully equipped boiler and approx 15 kW
output a flue gas temperature of approx. 150 °C is ob-
tained. It is therefore recommended that one or two turbu-
lators are removed or that a little is cut off each of them. It
is then possible to reduce the output of the burner.
The flue gas temperature should be at least 150 °C to
prevent condensation in the chimney. If one chooses to
remove the ceramics, at least two turbulators must be re-
moved because the flue gas temperature is otherwise too
low.
Correctly adjusted this combination means that the flue
gas emissions are low and the efficiency is high.
The adjustments must be carried out by a specialist.
Reconfiguring
• The burner is adapted and installed in the hatch.
• External operating thermostat and overheating ther-
mostat are installed in one of the hot water outputs.
• Remove the flame trough.
• Remove the adjustment wheel, remove the cladding
plate between the hatches, lift off the damper and seal
the primary air intake with the fireproof felt. Reinstall
the panel.
• Seal the secondary air intake with angled panels (or
with insulating felt) between the rear stones and the
boiler's inner wall on the left and right hand sides.
Sweeping description
• Remove the cover from the mounting points in the
boiler.
• Lift out the turbulators from the convection part.
• Sweep the convection part.
• Reinstall the turbulators.
• Reinstall the soot door.
