16 BOILER ROOM APPLICATION RECOMMENDATIONS

Gassero is strictly advising to use water softening unit before commissioning process for long term usage. Otherwise, system could
harm because of undesirable substances.
It is strictly advising to use plate heat exchanger, if there is floor heating system on line.
The devices that are commissioned outside of the required conditions, could be out of warranty.

As GASSERO, we recommend flushing in the system to prolong the life of system and boilers. No acid-based products should be used during flushing.
The boiler must be serviced annually. All this maintenance should be made by authorized service, water values and the water softening unit (resin, salt etc.)
values should be measured and maintained by service
Depending on the water conditions specified in the table, the problems that may occur in the boiler heat exchanger could make out of warranty.
The water used in the installation must be city-water. Never use well-water
Assembly and installation should made according to Gassero sample schemes.
Boiler (primary) pump must be selected to in accordence with the required pressure and flow rate.
The boiler (primary) pump must be in the direction of the installation return line to the boiler.
The system operating pressure should match with the working pressure of boiler. Sales Engineers could give consultancy.
All heat exchanger manufacturers; recommends to use of plate exchanger instead of the hydraulic separator for seperate the primary circuit and the secondary
circuit.
Domestic waste system could be used for condensate water. In system with a total power of 200 KW and above, a neutralization tank must be used.
Boiler output and input diameters must be strictly followed, other equipment should be selected according to the this diameters. In order to install other
equipment, the diameter of the boiler out should not be reduced.
It is mandatory to use a suitable diameter filter and check valve to the boiler return line pipe at each boiler turn.
Please contact our service department about detail of collector connection in installation of floor type boiler.
Additional zone control modules and sensors must be requested if there are equipment such as three-way valves and boilers that must be checked on the
heating collector. Please contact our Sales Engineer for more information.
Must use air separator and dirt separator with hydraulic separator.
In case the plate heat exchanger is used instead of the hydraulic separator as the system separator, expansion tank must be placed in the primary circuit.
If an automatic filling valve is used in the system, a water meter must be used for following how much water is added to the system.
In cascade systems, the sensor housing must be placed on the hydraulic separator or on the secondary flow line. If the system is separated by a plate heat
exchanger, place the sensor housing on the secondary circuit flow line.

Chimney connections must be made in accordance with the chimney types and regulations.
The flue gas analysis measuring probe (probe hole) must be opened by the flue company for each boiler.
Boiler chimneys should be extended by a minimum 1 meter from the boiler flue outlet direction and then connected to the chimney collector without elbows
or with elbows.
If the chimney connections passes over the boiler, the connections should be checked properly and water tightening should be provided. Water in the chimney
due to leaks may cause the system out of warranty. Adequate ventilation should be provided for the boiler room.
The operating pressure of the boilers in the natural gas installation is 21 Mbar. Therefore, it is necessary to use a regulator in the gas line. There should be a
minimum distance of 1-2 meters between the regulator and the boiler gas flange. There should be discharge line after regulator for discharge of the excess air.

In order to control the gas pressures, the manometer must be fitted before and after the regulator.
Gassero boilers are manufactured for heating and domestic water. Not suitable for commercial or industrial purposes. GASSERO shall not be held responsible
for any problems arising out of the design purpose.
