INSERTO 70 CRYSTAL ANGOLO
The ash drawer must always be inserted when the appliance is in operation.
The solid combustion residues (ashes) must be collected in a metal container that is hermetically sealed and fire 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 flammable
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.
Warn children that the device becomes very hot and that it must not be touched.
When using the wrong fuel or one which is too damp, due to deposits present in the flue, a flue fire is possible.
3.1.

FIRST-AID MEASURES

Should any fire arise in the stack or in the flue:
a) Close the feeding door.
b) Close the registers of combustion air
c) Extinguish the fire using carbon dioxide fire-fighting means (CO
d) Seek immediate intervention of FIRE BRIGADE.
DO NOT EXTINGUISH FIRE USING WATER JETS. When the flue does not burn any more please arrange an examination by a specialist
in order to find possible cracks and permeable points.
3.2.

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 flammable material
must not come in contact with temperatures higher than 65 °C.
WARNING: We cannot be made liable for a wrong operation of the plant, when it does not comply with the provisions of these
instructions or when it uses additional products not suitable for this device.

4. TECHNICAL DESCRIPTION

The appliance is made up of a steel chamber completely soldered and hermetic. The hearth is coated by single castiron sheets and
refractory plates (IRONKER).
The appliances are equipped with an integrated air circuit for the recovery of the heat made up of a galvanized steel carter
external to the heating body.
The insert is equipped with a sight door with ceramic glass (resistant up to 700°C). This allows a charming sight on burning
flames. Moreover, in this way, any possible leak of sparks and smoke is avoided. Under the hearth grating there is a easily
extractable ash drawer, also when the appliance works.
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.
The device is equipped with registers of primary and secondary air, with which it is possible to adjust the combustion air.
1A - PRIMARY air register
With the air register located under the door of the hearth (on the left), it is possible to adjust the air flow through the ash drawer and
the grating in direction of the fuel. The primary air is necessary for the combustion process during the ignition. In order to open the
passage of primary air the lever should be completely pulled.
The ash drawer has to be emptied regularly, so that ash cannot hinder the intake of primary air for the combustion. Primary air is also
necessary to keep fire 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
Under the door of the hearth (on the right) there is a secondary air register.
This valve must be opened (and therefore completely pushed), in detail, for the combustion of wood, so that unburnt carbon can be
subject to a post-combustion, increasing the yield and assuring the cleaning of the glass (see chapter NORMAL OPERATION).
It is possible to get the air SECONDARY directly from outside through a flexible tube (fireproof NOT furnished
