Regular maintenance is a legal requirement. In Italy it is required by Presidential Decree 412 of the 26th August 1993. It
is also essential for the safety, efficiency and durability of the boiler. Proper maintenance keeps consumption and emis-
sions down, and ensures that the boiler continues to operate reliably over time.
Have your boiler serviced either by
r
's Technical Assistance Service or by a qualified heating engineer.
Analyse the combustion fumes before commencing any maintenance. The results of fume analysis can give a clear idea
of what servicing or repairs are needed.
MAINTENANCE
OPENING THE DOOR
- Make sure that the top safety bolts (2) and bottom safe-
ty bolts (3) on the hinged side of the boiler are tight.
- Completely unscrew the main fixing bolts (1) and open
the door. (These bolts are captive in the door and can-
not be removed.)
b
The first time you open the door, remove the
spare hinge assembly ‘B’ (bushing (10), bolt (9),
and washer (11)) opposite the hinged side of the
door.
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 pressurised furnace. Proceed as fol-
lows to adjust the door seals:
- Push the door shut and tighten the main fixing bolts (1)
until the seals start to compress.
- Loosen the safety bolts (2 and 3) then fully tighten the
main door fixing bolts (1).
- Re-tighten the safety bolts (2 and 3).
b
Make sure that the door is properly adjusted after
every maintenance operation.
- Turn the system’s main power switch OFF
- Close the fuel shut-off cocks.
