5 INSPECTION AND MAINTENANCE

5.1 Why is regular maintenance important?

Heating systems require regular maintenance and service for the
following reasons:
− to maintain a high level of efficiency and to operate the
system economically (low fuel consumption),
− to achieve a high level of operational reliability
− to maintain the cleanest possible combustion
The operator is required to have the entire heating system at least
once a year maintained, serviced and cleaned.
We recommend that an annual inspection and as-required ser-
vice contract is signed.
The servicing work carried out should be recorded.
Burner servicing should be carried out in accordance with the in-
structions of the burner manufacturer.

5.2 Maintenance

Regular maintenance is a legal requirement. It is also essential for
the safety, efficiency and durability of the boiler. Proper mainte-
nance keeps consumption and emissions down, and ensures that
the boiler continues to operate reliably over time.
Have your boiler serviced either by
vice or by a qualified heating engineer. Analyze the combustion
exhaust gases before commencing any maintenance. The results
of the flue gas analysis can give a clear idea of what servicing or
repairs are needed.
− Turn the system's main power switch OFF
− Close all the gas cocks.

NOTICE:
− All cover plates, enclosures, and guards must be in place at
all times, except during maintenance and servicing.
Analyze the combustion flue gas before commencing any main-
tenance.
The results of flue gas analysis can give a clear idea of what servic-
ing or repairs are needed.

under the caps (3) holding the door in place.
ADJUSTING THE DOOR
Make quite sure that the door presses uniformly all around the
double seal to prevent dangerous fumes escaping into the air from
the pressurized furnace. Proceed as follows to adjust the door
seals:
System A
− Fit the door and tighten the main fixing bolts (2) until the
seals start to compress
− Loosen the safety bolts (1) then fully screw in the main door
fixing bolts (2)
− Make sure that the door is properly adjusted after every
maintenance operation.
System B
− Put the door in its correct position and tighten the main
locking screws (4) until the packing starts to be compressed.
