•Technological connection and appliance installation must be carried out by a qualified
staff, who is authorized to release a conformity certificate according with the normative
in force and current standards.
•All the normative concerning civil town planning and/or industrial in force must be
respected inside the installation roomof the appliance.
•All laws, standards and regulations in force on the installation site must be observed,
regarding: flues, electricity, water and steam, drains and wastedisposal,
•The appliance should be connected to an electrical plant suitable with the declared
electrical power ofthe appliance itself(see data plate).
•The manufacturer disclaims all responsibility caused by incorrect installation,
using, tampering, maintenanceor no respectof normative inforce.
•In order to avoid problems arising from residuals and/or deposit it is deeply
recommended to effect a complete washing of the plant (specially by new plants) before
connecting the appliance.
•Cut-off cocks must be installed out of the appliance, which permits to insulate the stove
in casethe thermal plant should be disconnected for maintenance and/or repair purposes.
•Flexible tubes are preferred to connect the appliance to the plant.
•Verify that the thermal plant is suitable with declared power ofthe appliance. The values
are reported on the technical data plate, which is placed on the appliance, a copy of it is
at tach ed in th is manual.

Directions:
The appliance is equipped with a security valve, which (in case that for any reason the
pressure of the thermal plant is exceeding 3 bar) intervenes, discharging the fluid
contained into the boiler. In order to avoid annoying outlets of water (not due to
problems of the appliance) generated by overpressure of the hydraulic plant, we
recommend to install a pressure reducing valve regulated at 2 bar, placed before the
thermal plant charging cock.
The eventual intervention of the security valve brings forth outlets of water and/or
steam, which flows on the floor, therefore the plant should be prearranged so that the
valve intervenes effectively only for real necessity and not for other causes, such as
overpressures due to an incorrect plant.
In case of outlets of the thermal plantfluid, due to the intervention of the securityvalve,
LINCAR S.p.A. declines any responsibilityfor eventual damages to floors or what else
had comein contact with thefluid.
During the operating phase of the appliance, speciallyat reduced heating power (owing
to the high efficiencyof the heat exchanger) the combustion products, convoyed into the
chimney, mayreach temperatures which maycause condense.
In order to avoid scalingsand or other inconvenient due to condense, use well insulated
flues and condense collection systems, which are normallyavailableon the market. As
forseen bythe local standars.

PRODUCTION OFDOMESTIC WATER
Mod. 740 – 840. The production of domestic water is possible EXCLUSIVELY when the
appliance is set at work with presence of fire. If the appliance is in OFF or STAND-BY
modality the production ofdomestic water will not be possible
This model is equipped with a rapid exchanger for the production of domestic water, if there
is a request of warm domestic water, the appliance signals to the electrocin card the necessity
of producing warm domestic water; the power level rises till pow. 5 is reached, in case the
selected domestic water temperature is exceeded, the appliance reduces the combustion
(modulation) in order to maintain the temperature. Once the domestic water is no longer
requested, the appliance returns on normal working cycle.
The time for the production of warm domestic water with a rapid exchanger may differ in
function of some factors; power level at the moment of request of domestic water, kind of
fuel, boiler temperatureselected, length oftubes, insulation ofheating plant.
Mod. 740/SA-840/SA- The production of warm domestic water with an appliance which is
NOT including a rapid exchanger depends from the type of heating plant, connected to the
appliance. Should you desire to have warm domestic water, you have to utilize an
accumulator out of the appliance, which will be heated by mean of appropriate deviations of
the heatingplant.
