La Nordica Monoblocco Ghisa 750 Piano [16/52] Description

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.

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 ue, a ue re is possible.

3.1. FIRST-AID MEASURES

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.

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 ammable material

must not come in contact with temperatures higher than 65 °C. Picture 2 at page 39 gives some examples of execution.

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. DESCRIPTION

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.

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 (Picture 8 at page 43)

With the air register located under the door of the hearth, it is possible to adjust the air ow through the ash drawer and the grating

Under the door of the hearth there is a secondary air register.

This register must be opened (and therefore the lever 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).

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