MAINTENANCE
Any maintenance and repair work must only be carried out by qualified personnel.
The manufacturer recommends Customers to contact the fondital Helpline UK for maintenance and repairs, they are best trained for that
procedure.
Appropriate boiler maintenance ensures efficient operation, environment preservation, and safety for people, animals and objects.
6.1.
Maintenance schedule
The boiler must be serviced at least once every year.
Isolate the appliance from the electric power supply before starting any maintenance procedure, involving replacement of
components and/or cleaning inside parts of boiler.
The combustion chamber internal insulating material contains aluminium silicate wool (RCF/ASW).
Tests on animals have shown that the inhalation of RCF/ASW powder can cause the cancer.
Avoid inhaling the powder released by such material.
Use the personal protection equipment as recommended.
Read the ECFIA code of conduct as well as the safety sheets before using the products.
For further information, please visit the website www.label.ecfia.eu
Only skilled personnel is allowed to handle this material.
Routine maintenance schedule are to include the following:
Inspections and checks:
- check visually general integrity of the boiler;
- check boiler and network gas supply for leakage;
- check inlet gas supply pressure to boiler;
- check boiler ignition sequence;
- check boiler combustion parameters by flue gas analysis;
- check the condition and seal integrity of the flue gas discharge pipes;
- check the state of combustion fan;
- check integrity of safety devices of the boiler in general;
- check for water leaks and oxidised areas on the boiler’s couplings;
- check efficiency of the system safety valve;
- check expansion vessel loading pressure;
- check safety flow switch, preventing low water pressure operation;
- check correct draining of condensate from the condensate trap installed on the boiler;
- check visually the flue discharge pipe throughout the flue length.
The following cleaning is to be done:
- clean the general interior of the boiler;
- clean the gas injectors;
- clean the air intake and flue gas discharge circuits;
- clean the heat exchanger (burner side);
- condensate trap and discharge ducts.
When checking the boiler for the very first time, also verify:
- boiler room suitability;
- diameter and length of flue gas system ducts;
- boiler installation in accordance to this “
Installation use and maintenance
” manual instructions.
Should the boiler not correctly operate, while not creating any danger to people, animals or property, inform the Fondital hel-
pline UK both verbally and in writing.
After servicing, complete the relevant Service Interval Record section of the Benchmark Checklist located on the inside back
pages of this document.
6.2.
Combustion analysis
The combustion parameters of the boiler, which have to be checked in order to determine efficiency and emissions, must be measured in
compliance with applicable legislation and standards, which are considered as fully transcribed in this manual.
