In the event that the water temperature exceeds the tripping temperature of the safety devices, immediately suspend the feeding
of wood, and make sure that the water temperature and the flame decrease, eliminating the causes of the overheating (if necessary
by closing the air register).
If the water system is connected in the thermo-fireplace, the hot water tap can be opened to speed up the cooling of the appliance.
Besides the adjustment of the air for the combustion, the intensity of the combustion and consequently the thermal performance of the
device is influenced by the stack. A good draught of the stack requires a stricter adjustment of air for combustion, while a poor draught
requires a more precise adjustment of air for combustion.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that the
combustion is not complete (it is necessary a greater quantity of secondary air).
8.2. ELECTRICAL POWER SUPPLY FAILURE
In the event of an unexpected electrical power supply failure during normal system operation, it will be necessary to carry out these simple
manoeuvres to prevent the water in the boiler starting to boil as a consequence of the lack of pump operation.
a) Close completely the primary and secondary air registers in order to smother the flame as much as possible.
b) Close the smokes register, if existing, to limit further coming of combustive air through possible cracks.
8.3. OPERATION DURING TRANSITION PERIODS
ATTENTION
:
never light for any reason if the installation is not completely full of water in order to avoid a serious damage of the
whole structure
. The installation must always be full of water even when the thermo-fireplace is not used. A possible no use during
winter season must be faced by adding antifreeze substances.
During transition periods when the external temperatures are higher, if there is a sudden increase of temperature it can happen that the
combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more frequently and increase the air
for the combustion. Then, load a reduced quantity of fuel in order to permit a rapid burning (growing up of the flames) and the stabilization
of the draught.
Then, check that all openings for the cleaning and the connections to the stack are air-tight.
8.4. USE AS A NORMAL STOVE.
ATTENTION: For no reason must the fire be ignited before the system has been completely filled with water; doing this would
lead to serious damage of the entire structure
.
Use as a normal stove is NOT envisioned!
In order to prevent water boiling in the boiler, when the thermoheating stove is in function, the circulation pump must be in function in order
to dispose of the heat given to the boiler water on the radiators.
9. SUMMER TIME
ATTENTION
: The installation must always be full of water even when the thermo-fireplace is not used. A possible no use during winter
season must be faced by adding antifreeze substances.
After having performed the cleaning of the hearth, of the stack and of the flue, removing completely the ash and other possible residuals,
close all doors of the hearth and the related registers.
It is suggested to perform the flue cleaning at least once a year; in the meantime, verify the actual state of the door seals, which do not
assure the good operation of the device, if they are not completely integral (i.e. if they do not adhere anymore to the door)! Therefore, it is
necessary to replace them.
In case of humidity of the room where the device is located, place the absorbing salts within the hearth.
To maintain the aesthetic appearance over time, protect the inside parts in cast iron with Vaseline.
Check the water level in the expansion tank and remove any air from the system by bleeding the radiators; also check to make sure that
the plumbing and electrical accessories (control unit, circulator) are working properly.
10. MAINTENANCE AND CARE
Check the external air intake, by cleaning it, at least once a year.
The stack must be regularly swept by the chimney sweeper.
Let your chimney sweeper in charge of your area check the regular installation of the device, the connection to the stack and the aeration.
IMPORTANT:
You should only use spare parts approved and supplied by La NORDICA. Please contact your specialized retailer if you
require spare parts.
YOU MUST NOT MAKE ANY CHANGES TO THE DEVICE!!!
10.1. CLEANING THE FLUE
The correct lighting phase, the use of proper quantities and types of fuels, the correct position of the secondary air regulator, enough
draught of the chimney-flue and the presence of combustion air are the essential elements for the optimal functioning of the appliance.
