The solid combustion residues (ashes) must be collected in a metal container that is hermetically sealed and re resistant. The appliance

must never be lit in the presence of gaseous emissions or vapours (for example: glue for linoleum, petrol, etc,). Do not place ammable

materials in the vicinity of the appliance.

During the combustion, thermal air is emitted by involving the heating of areas, door and glass hearth, of the door handles or controls,

of the smokes pipe and, in case, of the front part of appliance. Avoid to touch those parts without a protective clothing or without

accessory tools (gloves resistant to heat, control devices).

Ensure children are aware of these dangers and keep them away from the furnace when it is on.

c) Extinguish the re using carbon dioxide re-ghting means (CO

2

dust).

d) Seek immediate intervention of FIRE BRIGADE.

DO NOT EXTINGUISH FIRE USING WATER JETS. When the ue does not burn any more please arrange an examination by a specialist

in order to nd possible cracks and permeable points.

4.2. BEAM PROTECTIONS

Considering the irradiation of the hearth, it is necessary to be particularly careful in protecting the beams while designing your stack.

Consider the proximity of beams to the external surfaces of the hearth, on one side, and the irradiation of the glass door, usually very close

to the beams, on the other side. In any case, it has to be considered that the internal or lower surfaces of this beam in ammable material

must not come in contact with temperatures higher than 65 °C. Picture 2 at page 59 gives some examples of execution.

of cast iron. The combustion chamber assembly is air-tight by welding and covered with a galvanized sheet metal carter.

The devices 800 are equipped with a hearth with double thickness rear part made up of a drilled extractible plate.

Through these holes, pre-heated air gets into the hearth; in this way, it is possible to achieve a post-combustion with an increase of the

yield and a reduction of emissions of unburnt gases.

The sight door is assembled on extensible ball guides, which assure a robust and silent operation reliable in time.

The door lifting counter-weight is supported by two sturdy chains with related pinions.

The ceramic glass (resistant up to 700 °C) of the door allows a charming view on burning ames and avoids any leak of sparks and smoke.

The heating of the room occurs:

a) by convection: the passage of air through the coating and the covering hood releases heat in the room.

b) by radiation: through the sight glass and the steel body, heat is radiated into the room.

necessary to keep re live.

During the combustion of wood, the primary air register must be opened only a few, since otherwise the wood burns quickly and the

device can overheat (see chapter NORMAL OPERATION).

2A - SECONDARY air register (Picture 8 at page 63)

Secondary air, passing in the façade’s two side struts, heats up and triggers double combustion while also cleaning the glass door

(turn the regulator fully to the right). If you move the lever to the centre, the appliance (800 model) operates at a reduced rate:

primary air is closed and the ow of secondary air is halved (see chapter NORMAL OPERATION).

The adjustment of the registers necessary to reach the rated caloric yield is the following one:
