circuit board: it intervenes directly sending the product
into alarm conditions until it has fully cooled down, in
the event of: fumes motor breakage, pellet feed motor
breakage, black out (if above 10 seconds), failed ignition
Door micro switch: With the door open, the operation of
the burn pot cleaning system is blocked
electronic pressure switch: in the event of inadequate
depression, it sends the machine in alarm conditions
f 2.5 A 250 v fuse (stoves): protects the machine from
violent current surges
85°c calibrated mechanical bulb with manual rearm:
intervenes by blocking fuel feed whenever the pellet tank
t° reaches the limit of 85°C. rearm must be performed
by qualified staff and/or the manufacturer's technical
after-sales assistance.
Pellet tank temperature control probe: if the tank over-
heats, the machine automatically modulates to return to
normal temperature values (* in the relevant models)
Mechanical air pressure switch: blocks the pellet in the
event of insufficient depression (in the relevant models)

One must also bear in mind all laws and national, regional,
provincial and town council Standards present in the country
in which the appliance has been installed.
terMS AnD DefinitiOnS
Aeration: Air renewal is required both for the disposal of
the combustion products, and to prevent mixtures with a
hazardous content of non-combusted gases.
closed hearth appliance: Appliance designed for operation
*
with closed combustion chamber.
forced draught appliance: Appliance with ventilation in the
fumes circuit and combustion with fumes flow at a positive
pressure with respect to the environment.
-
chimney: Structure consisting in one or several walls
containing one or several outflow airways.
The purpose of this predominantly vertical element is to expel
*
the combustion products at a convenient height from the
ground.
Smoke duct: Component or components that connect the
*
outlet of the heat generator to the chimney.
chimney cap: Device that placed on the chimney outlet
allows the dispersion of the combustion products even in
*
presence of adverse weather conditions.
condensation: Liquid products which form when the fumes
temperature is lower or equal to the water dew point.
Ducting pipe: Pipe made up of one or several predominantly
*
vertical elements, specifically suitable for collecting and
expelling the fumes, as well as to withstand the relative
components and any condensate over time,
suitable to be installed in a chimney, existing or new technical
*
compartment, even in new buildings.
Sealed installation: Installation of an appliance with sealed
operation, so that all the air required for combustion is taken
from outside.
Maintenance: Set of procedures required to ensure and
maintain safety and functionality over time and maintain the
efficiency of the system within the prescribed parameters.
chimney system: Chimney installed using a combination
of compatible components, manufactured or specified by a
sole manufacturer whose product liability covers the entire
chimney.
fumes exhaust system: Flue gas exhaust system, independent
from the appliance made up of a smoke duct, chimney or
individual flue and chimney cap.
radiation area: Area immediately in front of the hearth in
which the radiant heat caused by combustion is diffused.
reflux area: Area beyond the extrados of the roof in which
overpressure or depressions occur, which may affect the
proper discharge of the combustion products.
