CLEANING THE ASH
One recommends adequate cleaning of the hearth for proper combustion. To remove the ash from the hearth use a metal scoop and brush
and store the ash in non-flammable containers for transport.
Hot ashes must not be stored outside unsupervised or thrown into the rubbish bin. Allow it to cool in the open air in a
metal container.
CLEANING THE REFRACTORY PARTS (ALUTEC®)
They do not require any cleaning as the characteristic of this material (ALUTEC®) is that it does not absorb soot but instead it repels it when
the fireplace is hot. After the start-up stage in which the fireplace tends to tarnish, the refractory parts will turn white again, starting from
the base of the flame, when the combustion chamber reaches working temperature (~ 400° C).
If this phenomena does not take place it may be caused by:
• Damp or resinous wood that does not emit sufficient heat or that dirties the combustion chamber
• Chimney with poor performance and therefore smoke stays in the combustion chamber for too long, dirtying the firebox
• Chimney with low performance that does not allow the closed fireplace to reach high efficiency and therefore adequate temperatures
for the refractory parts.
Never clean the refractory parts with a damp cloth or other as it could get stained.
If required use a dry paintbrush to remove thick accumulations of soot.
Should the Alutec not whiten, it must not be considered as a defect in light of the warnings and indications reported
above.
CLEANING PERFORMED BY A QUALIFIED TECHNICIAN
CLEANING THE CHIMNEY
We recommend the mechanical cleaning of the flue pipe at least once a year; excess build-up of unburned waste could cause problems
with the smoke outlet pipe and start a fire in the flue pipe itself. To clean the chimney flue by accessing from the appliance, remove the
smoke deflector: to remove it properly lift it from the front part and make it simultaneously come forwards to free it from the resting
supports at the back.
