3. Open the oven door (if present) in order to favour the elimination of the internal heat.
4. Open the flue gas register (if present ) in this way, it will deviate the residual heat still produced towards the chimney.
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.
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.
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 appliance during summer use to avoid recurrent interventions of the DSA valve
which may jeopardize its good operation.
To use the wood burning appliance exclusively for cooking foods for example during the summer period it is necessary to lift the movable grill
(If present) to the maximum height to bypass as much as possible the surfaces of exchange able to yield heat to the water; the smoke register
shall be kept open (If present) to encourage the exit of hot smoke having heated the cast iron plate (cooking function – HOTPLATE USE).
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: THE MAINTENANCE MUsT BE CARRIED OUT ONLY AND EXCLUsIVELY WITH COLD DEVICE. You should only use
spare parts approved and supplied by Dal Zotto . Please contact your specialized retailer if you require spare parts. YOU MUsT NOT
MAkE ANY CHANgEs TO THE DEVICE!!!
gLAss CLEANINg
Thanks to a specific inlet of secondary air, the accumulation of dirty sediments on the glass-door is reduced with efficacy. Nevertheless this can
never be avoided by using solid fuels ( particularly wet wood ) and it has not to be understood as a defect of the appliance.
IMPORTANT: The cleaning of the sight glass must be carried out only and exclusively with cold device to avoid the explosion
of the same. For the cleaning, it is possible to use specific products or a wet newspaper paper ball passed in the ash to rub it. Do
not use cloths, abrasive or chemically aggressive products by cleaning the hearth glass.
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 and for the
cleaning of the glass.
BREAk OF gLAssEs: given that the glass-ceramic glasses resist up to a heat shock of 750°C, they are not subject to thermal
shocks. Their break can be caused only by mechanic shocks (bumps or violent closure of the door, etc.). Therefore, their
replacement is not included in the warranty.
