TECHNICAL DESCRIPTION
La Nordica thermoheating stoves are suitable for heating homes using a centralised heating system made up from
radiators or heat convectors entirely or partially replacing the traditional gas or diesel oil boiler. They are ideal for
holiday apartments and week-end homes or as auxiliary heating throughout the entire year.
Wooden logs are used ad fuel.
The fireplace is found inside the boiler, is built in 4 mm thick steel and is reinforced using welded nails. The water in
the heating system circulates in the boiler, which absorbs the heat produced in the fireplace.
A swivelling, removable grid is found inside the fireplace.
The hearth is equipped with a panoramic door with ceramic glass (resistant up to 700 °C). This allows a wonderful
view on the burning flames and avoids any possible output of sparks and smoke.
The heating of the environment is made:
a) radiation: the heat is radiated into the environment through the panoramic window and the hot external
surfaces of the thermoheating stove;
b) by conduction: radiators or heat convectors of the centralised system fed by hot water produced by the
thermoheating stove itself.
The thermoheating stove has regulators for primary and secondary air, with which the combustion air is adjusted.
PRIMARY air control
With the primary air control (Picture 1
A) is adjusted the passage of
air through the ash drawer and the grate in the fuel direction. The
primary air is necessary for the combustion process. The ash
drawer must be regularly emptied, so that the ash does not obstruct
the primary air entry. Through the primary air the fire is also kept
alive.
During wood combustion, the register of primary air must be
opened only for a while, because otherwise the wood burns fast
and the stove may overheat. For the correct arrangement, see the
table on chapter 10.
SECONDARY air control
Over the door of the hearth there is the secondary air control
(Picture 1
B). This regulator must be open (the lever must be
moved to the right), especially for wood combustion, so that un-
burnt carbon does not undergo a post-combustion. See chapter 10.
Through this register it is possible to adjust the power of the stove.
Leaving it slightly open, according to the flue of the chimney, it is
possible to keep the glass clean.

RULES FOR INSTALLATION
Installation of the thermo stove and auxiliary equipment in relation to the heating system must comply with all current
Standards and Regulations and to those envisioned by the law.
Installation relating to the connections of the system, commissioning and the check of the correct functioning must be
carried out in compliance with the regulations in force by authorised professional personnel with the requisites
required by the law, being national, regional, provincial or town council present in the country within which the
appliance is installed, besides these present instructions.
Installation must be carried out by authorised personnel who must provide the buyer with a system declaration of
conformity certificate and will assume full responsibility for final installation and as a consequence the correct
functioning of the installed product.
NORDICA S.p.A. cannot be held responsible for lack of respect for such precautions.
Before installation, accurately wash the pipes of the system in order to remove any residuals that could compromise
the correct functioning of the appliance.
IMPORTANT:
a) In case of water leaking, close the water supply and promptly warn the after sales technical service;
b) The system working pressure must periodically be checked.
c) If not using the boiler for a long period of time, it is recommended that the after sales technical service is
contacted to carry out at least the following operations:
-
close the water taps of both the thermal system and the domestic hot water system;
-
empty the thermal system and the domestic hot water system if there is risk of freezing.
La Nordica S.p.a. declines all responsibility for damage to objects and/or injury to persons caused by the
system. Moreover, it is not liable for the product that has been modified without authorisation and also for
the use of non-original spare parts
