Our responsibility is limited to the supply of the appliance. Your plant has to be carried out in compliance with the
state of the art, according to the provisions of these instructions and good professional practice, by qualified
personnel, acting for companies authorized to acquire the whole responsibility for the whole plant.
La NORDICA S.p.A. cannot be made liable for any product modified without authorization, as well as if not

DESCRIPTION
The appliance is made up of a series of elements in cast iron joined to one another by a fixed joint, while the seal is
assured by refractory putty. The assembly is supported by tie rods and nuts located outside the heating body and
coated with a carter made of varnished and galvanized sheet heat-resistant.
The appliances are equipped with an integrated air circuit for the recovery of the heat made up of deflectors (radiant
fins) on all external surfaces of the heating body.
The appliances are equipped with a hearth with double thickness rear part, made up of a drilled extractible and
reversible plate.
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.
The heating of the room occurs:
a) by convection: the flow of the air through the coating and the covering hood of the hearth releases heat in
the room.
b) by radiation: through the sight glass and the cast iron body, heat is radiated in the room.
The appliance is equipped with primary and secondary air registers, which adjust the combustion air.
1A - Picture 1 Primary air register
With the air register located under the door of the hearth, it is
possible to adjust the air flow through the ash drawer and the
grating towards the fuel. The primary air is necessary for the
combustion process.
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 just a few, since otherwise wood burns
quickly and the appliance can overheat.
2A - Picture 1 Secondary air register
On the door of the hearth to the right, there is a secondary air
register.
This valve must be opened (and therefore shifted to the right), 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 CHAP. 12).
3 - Smoke valve register
Combustion is not always regular; as matter of fact both
atmospheric conditions and outside temperature can influence it
by modifying the depression in the stack. For this reason, all inserts are equipped with an adjustable smoke valve
with automatic opening allowing an optimal adjustment of the draught.
Through the lever located on the bottom left, it is possible to position the smoke valve correctly (all to the left = all
open). Should the door open independently from its position, the smoke valve opens automatically.
