Maintenance Of The Extensible Guides; Summer Stop; Routine Maintenance Performed By Qualified Technicians; Gaskets - Nordica MONOBLOCCO GHISA 750 Manuel Utilisateur

MAINTENANCE OF THE ExTENsIBLE gUIDEs

To work silently, as well as in a reliable and robust way, the doors are fastened to the extensible ball guides. By using the device continuously,
the lubricant of the guides tends to run out progressively in time making their sliding more difficult and noisy. For this reason, together with
each device a high temperature grease is supplied in order to make the lubrication of the guides possible for the user, in case it becomes
necessary (excessive noise or reduction of smoothness). After having completely lifted the door of the stack, using a syringe, apply internally
on the track on a visible point, as high as possible, two grease balls (corresponding to 0.5 ml of the graduated scale of the syringe).
Pay attention not to exceed the suggested quantity. Repeat the same operation on the other track and lift and lower the door many
times so that the grease distributes on all balls.
CAUTION: use exclusively the grease supplied by La NORDICA.

sUMMER sTOP

After cleaning the hearth, chimney and hood, totally eliminating the ash and other eventual residues, close all the doors of the hearth and
the relevant registers; in case you disconnect the appliance from the chimney you must close its openings in order to let work others possible
appliances connected to the same flue.
We suggest performing the cleaning operation of the flue at least once per year; verifying in the meantime the actual status of the rope seals,
which cannot ensure the good operation of the equipment if they are not in good condition and are not making a good seal! In this case the
seals must be replaced.
In presence of dampness in the room where the product has been placed, we advise you to put absorbent salts into the hearth.
If you want to keep for long the aesthetic look of the cooker it is important to protect its internal walls in row cast iron with neutral
Vaseline.

ROUTINE MAINTENANCE PERFORMED BY QUALIFIED TECHNICIANs

Routine maintenance must be performed at least once a year.
Using wood as solid fuel, the generator requires annual routine maintenance, which must be performed by a qualified technician, using
only original spare parts.
Failure to comply can jeopardise the safety of the appliance and make the warranty null and void.
Respecting the frequencies of cleaning reserved for the user described in the use and maintenance manual, the generator is guaranteed
correct combustion over time, preventing any anomalies and/or malfunctioning that could require more interventions of the technician.
Requests for routine maintenance are not contemplated in the product warranty.

gAskETs

The gaskets guarantee the tightness of the product and its consequent good functioning.
They must be controlled periodically. They must be replaced immediately if they are worn or damaged.
These operations must be carried out by a qualified technician.

CONNECTION TO THE FLUE

Vacuum and clean the pipe that leads to the flue yearly or any time that it is necessary. If there are horizontal tracts, the residue must be
removed before it can prevent the passage of the fumes.

CALCULATION OF THE THERMAL POWER

There is not an absolute rule for calculating the correct necessary power. This power is given according to the space to be heated, but it
depends also largely on the insulation. On an average, the calorific value necessary for a properly insulated room is 30 kcal/h per m
external temperature of 0°C).
Given that 1 kW corresponds to 860 kcal/h, it is possible to adopt a value of 35 W/m
Let's suppose one wishes to heat a room of 150 m
W/m = 5250 W or 5,25 kW. As main heating, a 8 kW device is therefore sufficient.
