direction to reduce combustion. As this is an extremely precise device, it is advisable to turn it carefully and never
force the knob.
FLUE GAS Register (Picture 1 Pos.D)
(Conversion from the cooker HOTPLATE USE – OVEN USE function to the cooker HEATING function)
In the central part of the instrument panel, there is the flue gas register, which can be recognised from its enamelled,
labelled knob.
When the register is positioned to the LEFT (on the pan symbol), the combustion gases flow above and around the
oven (oven function – HOTPLATE USE – OVEN USE); when positioned to the RIGHT (on the water symbol), the
gases flow near the boiler, increasing the temperature evenly, favouring water heating inside it (cooker function
HEATING USE).
IGNITION Register (Picture 1 pos. E).
On the front of the cooker, between the protective handrail and the flue gas register, there is the ignition register
control lever, which can be recognised by a chrome-plated knob.
This register must only be used to facilitate the ignition of fuel in the cooker. Pull the lever outwards from the cooker
(register open).
IMPORTANT : during normal cooker operation, the register lever must remain completely inserted (pushed inwards
on the cooker). In this way avoiding excessive fuel consumption and poor thermocooker output (register closed).

INSTALLATION REGULATIONS

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 things and/or persons caused by the system. In
addition, it is not responsible for any product modified without authorisation and even less for the use of non
original spare parts.
Your local chimneysweep must be informed of the installation of the thermocooker, so that he can check its correct
connection to the flue and the level of efficiency of the flue itself.
NO MODIFICATIONS CAN BE CARRIED OUT TO THE APPLIANCE.
Before installation, check whether your floor can support the weight of the Thermocooker.
WARNING ensure the device is placed perfectly level and that the diameter of the smoke exhaust pipe is that
required.
Connection of more that one stove to the same chimney is not allowed.
It is advisable to have your local chimneysweep check both the connection to the chimney and the sufficient flow of air
for combustion in the place of installation.
The diameter of the opening for connection to the chimney must at least correspond to the diameter of the flue gas
pipe. The opening must be equipped with a wall connection for the insertion of the exhaust pipe and a rosette.
The unused flue gas exhaust stub pipe must be covered with its respective cap.
The DSA thermo cooker models, can be installed in both an OPEN expansion VESSEL system (see chapter 3.1) and
a CLOSED expansion VESSEL system (see chapter 3.2).
