7. MAINTENANCE
To maintain the high degree of efficiency of the unit, it is
necessary to service it regularly. Depending on the type
of operation, annual or semi-annual servicing is
recommended.
The boiler and firing must be inspected by a qualified
specialist in accordance with the official regulations.
Before performing any work on the unit, it must be
disconnected from the mains and the fuel supply
must be shut off.
DANGER
:
The device contains components made of synthetic silicon mineral fibers (ceramic
and glass fibers, insulation wool). In order to avoid all types of health hazards, suitable
clothing and a protective mask must be worn for work on or with these components.
7.1. Periodical checks and maintenance operations
- Check manometer with circulation pump off. Low water
or pressure level indicates that the system must be filled
up with water.
- Check that the expansion chambers function properly.
- Check safety valves as well as heating and hot water
system blowers.
- Carry out burner maintenance according to the
recommendations given in the burner manual.
- Check fuel oil level.
- Clean boiler and chimney.
7.2. Boiler cleaning
Boiler should be cleaned by your chimney sweeper and engineer.
The cylindrical type construction of the boilers makes cleaning much easier to perform. However, we recommend that
heating surfaces in fuel oil boilers be cleaned with appropriate chemical products. Your installation contractor, as an
engineer, will know how to best advise you.
