KOVARSON
which water production. The main design choices made by
ADAX
for the – the total pre-mix microflame burner combined with a steel
heat exchanger for heating and a rapid heat exchanger for DHW
– the sealed combustion chamber which can be classified
"Type C" or "Type B" in relation to the room where the boiler is installed, depending on the smoke outlet configuration adopted during installation
– the command and control microprocessor electronic board
provides efficient management of both heating and hot water production. It can also be connected to a remote control with an Open Therm protocol or to room thermostat and/or external sensor. If connected to an external sensor, the boiler temperature varies on the basis of the external temperature according to a selected optimal climatic curve providing
significant energy and economic savings. Other special features of the – the anti-freeze function which activates automatically if the
temperature of the water inside the boiler falls below the
threshold of the value set at parameter "PAR 10" and , if there
is an external sensor, if the external temperature falls below
the threshold of the value set at parameter "PAR 11" – the anti-blocking function of the pump and diverter valve. This
activates automatically every 24 hours if no request for heat
has been made – the chimney sweep function lasts 15 minutes and makes the
job of the qualified technician easier when measuring the
parameters and combustion efficiency – domestic hot water comfort function which allows the time
necessary for the hot water to become available to be reduced
and ensures that the temperature is stable – screen display of the operating and self-diagnostic
parameters with error code display when the fault occurs.
This makes repair interventions easier and allows appliance
operation to be restored correctly.

Before removing an old heat generator from an existing system, it is recommended that the user: – puts a descaling additive into the water system – allows the system to work with the generator active for a few
days
– drains the dirty water from the system and flushes the system
with clean water once or more than once. If the old generator has already been removed or is not available, replace it with a pump to circulate water in the system and then proceed as described above. Once cleaning operations have been carried out and before installing the new appliance, it is recommended that a fluid is added to the water system to protect it from corrosion and deposits.
Fig. 12
2.5 New installation or installation of a replacement appliance
When
ADAX
boilers are installed on old systems or systems requiring updating, it is recommended the installer checks that: – the connecting flue pipe is suitable for the combustion
temperature of the appliance, calculated and manufactured in compliance with Standards, that it is as straight as possible, air tight, isolated, with no obstructions or restriction and that it has appropriate condensate collection and evacuation systems
– the electrical system has been manufactured in compliance
with specific Standards and by professionally qualified personnel
– the fuel delivery line and the tank (LPG) comply fully with
specific Standards
– the expansion vessel ensures total absorption of the fluid
dilation in the system
– the pump flow-head performance is sufficient for the system
characteristics
– the system is clean, free of any sludge, deposits, de aerated
and air tight. For system cleaning, please refer to the relevant paragraph.
CAUTION
For further information on the type of additive and usage, please contact the appliance manufacturer.
2.7 Water system treatment
When filling and restoring the system it is good practice to use water with: – aspect: clear if possible – pH: 6÷8 – hardness: < 25°f. If the water characteristics are different from those indicated, it is recommended that a safety filter is used on the water delivery pipe to retain impurities, and a chemical treatment system to protect against possible deposits and corrosion which could affect boiler operation. If the systems are only low temperature systems, it is recommended that a product is used to prevent the development of bacteria. In any case, please refer to and comply with Legislation and specific Technical Standards in force.
2.8 Boiler installation
ADAX
boilers leave the factory with a paper template for installation onto a solid wall. For installation: – position the paper template (1) on the wall (2) where the boiler
is to be mounted – make the holes and insert the expansion plugs (3) – hook the boiler onto the plugs.

CAUTION
The manufacturer declines all liability for any damage caused by an incorrect implementation of the smoke outlet.
2.6 Cleaning the system
Before installing the appliance on a newly constructed system or replacing a heat generator on an existing system, it is important that the system is thoroughly cleaned to remove sludge, slag, dirt, residue etc.
