2. 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 fireplace has a panoramic door with glass ceramic (resistant up to 700°C). This allows a fascinati ng view of the
burning flames. Moreover, sparks and smoke cannot escape.
Room heating takes place by:
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.
Adjustment of PRIMARY air (lower lever) (Pos. A Picture 1)
The passage of air through the ash box and the grid in the direction of the fuel is
adjusted using the regulator positioned in the bottom left of the fireplace door. The
primary air is necessary for the combustion process. The ash box must be emptied
regularly, so that the ash does not obstruct the entry of the primary air for
combustion. The fire is also kept alive by the primary air.
During the combustion of wood, the primary air adjuster must only be slightly open otherwise the wood burns quickly
and the thermoheating stove can overheat.
When the lever is completely extracted, the regulator is open; with the lever inserted, the regulator is closed.
Adjustment of SECONDARY air (upper lever) (Pos. B Picture 1)
The secondary air regulator is found above the fireplace door. This regulator must be open (the lever must be moved
to the right), in particular for the combustion of wood, so that the unburned carbon can undergo post-combustion. See
paragraph 10. This regulator can be used to adjust the performance of the thermoheating stove.
Leaving it slightly open, depending on the chimney effect, it is possible to keep the glass clean.

3. REGULATIONS 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
Your chimney sweep must be informed regarding the installation of the thermoheating stove, so that he can check the
correct connection to the flue and the level of efficiency of the latter.
Modifications cannot be made to the appliance.
Before installation, check that your floor can support the weight of the thermoheating stove.
