NORMA - S IDRO DSA
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).

10.1. USE OF THE OVEN (If present)

Thanks to the air flow for the combustion, the temperature of the oven may become remarkably affected. A sufficient flue of the chimney
and of the channels, well cleaned for the flow of burning smokes around the oven are fundamental for a good cooking result. The oven pan
may be located on different plans. Thick cakes and big roasts must be introduced in the lowest level. Flat cakes and biscuits must reach
the medium level. The upper level may be used to heat or grill.

10.2. 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.
1. Raise the moveable furnace grill (if present ) to the highest level in order to reduce the exchange surface exposed to the heat of the
flame.
2. Close the primary and secondary air registers in addition to turning the thermostat to 0 ( if present).
3. Open the oven door (if present) in order to favour the elimination of the internal heat.
4. Open the flue gas register ; in this way, it will deviate the residual heat still produced towards the chimney.

10.3. OPERATION IN TRANSITION PERIODS

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-tigh.
In case of doubt, do not operate the product.
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.

10.4. SUMMER USE

The system must be completely filled with water. The absence of water in the system would lead to serious damage of the entire
structure. 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.
In order to prevent water boiling, the circulation pump must be always in function in order to drain on the radiators, or on the puffer, or on
any other thermal absorption structure the heat given from the boiler to the water. If the pump does not circulate or for any reason the
water temperature exceeds 95°C, acts the DSA valve discharging heat in the throughway water. It is recommended to supervise
the water temperature in the thermoproduct during summer use to avoid recurrent interventions of the DSA valve which may
jeopardize its good operation.

11. 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 stove 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.
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.
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. The installation must always be full of water even when the thermo-fireplace is not used.
