Connection And Maintenance Of Ventilation; Allowed / Not Allowed Fuels - LA NORDICA INSERTO CRYSTAL 50 Manuel Utilisateur

CONNECTION AND MAINTENANCE OF VENTILATION

The control unit and the plant must be installed and connected by authorized personnel according to the standards in force
(see chapter GENERAL PRECAUTIONS).
ATTENTION: the control unit and the feeding cable must not be in contact with hot parts.
Our products are equipped with tangential fans suitable to improve the distribution of heat through the ventilation exclusively of the
installation room (see chapter TECHNICAL DATA SHEET).
The lighting and the adjustment is carried out through the proper standard supplied control unit that has to be installed far from any direct
heat source.
The selection of the kind of insert to be connected is in the control unit and has to be done by moving the small bridge 7 as shown hereafter
before the INSERT starts to operate (see chapter SERIES VENTILATION).
This operation must be done without electric energy!!
On our products, it is possible to install OPTIONAL ventilation kits suitable to improve the distribution of heat by ventilation only either of the
installation room or of the adjacent local (see chapter VENTILATION HOOD OR ADJACENT LOCAL).
For the connection of the ventilation kit, please see the instructions manual CONNECTION AND MAINTENANCE OF VENTILATION OPTIONAL.
CONNECTION: Connect the power supply cable of the control unit to a bipolar switch respecting at least a 3 mm distance between the
contacts (power supply 230 V~ 50 Hz, it is necessary to provide for the correct connection to the grounding plant). This operation must be
done without electric energy!!
WARNINg: The COMMAND must be connected to the mains with a differential line cut-off switch according to the regulations in
force. Correct operation of the command is assured only for the proper motor for which it has been manufactured. Improper use
relieves the manufacturer from each responsibility.

ALLOWED / NOT ALLOWED FUELs

Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 3 logs should be loaded. The pieces of wood
should have a length of ca. 20-30 cm and a maximum circumference of 30-35 cm.
Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may damage the device,
since these have a very high calorific value.
The wood used as fuel must have a humidity content lower than the 20% and must be stored in a dry place. Humid wood tends to burn
less easily, since it is necessary a greater quantity of energy to let the existing water evaporate. Moreover, humid content involves
the disadvantage that, when temperature decreases, the water condensates earlier in the hearth and therefore in the stack causing
a remarkable deposit of soot with following possible risk of fire of the same.
Fresh wood contains about 60% of H
It is necessary to place this wood in a dry and ventilated place (for example under a roofing) for at least two years before using it.
Besides others, it is not possible to burn: carbon, cuttings, waste of bark and panels, humid wood or wood treated with
paints, plastic materials; in this case, the warranty on the device becomes void.
Paper and cardboard must be used only to light the fire.
The combustion of waste is FORBIDDEN and would even damage the appliance and the flue, causing health damages and claims
by the neighborhood owing to the bad smell.
The wood is not a fuel which allows a continuous operation of the appliance, as consequence the heating all over the night is not
possible.

ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages the
cast iron parts (cleavage) of the product.
The declared technical data have been achieved by burning beech wood class "A1" according to the requirement UNI EN ISO 17225-5 and wood
moisture content less than 20%. By burning a different kind of wood the efficiency of the product itself could change and some specific adjustments
on the appliance could be needed.
