ment line during normal boiler functioning. If the rubber

2.17 Maintenance
Regular maintenance is a legal requirement. It is also essen-
tial for the safety, efciency and durability of the boiler. Prop-
er maintenance keeps consumption and emissions 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 qualied heating engineer.
Analyse the combustion fumes before commencing any mainte-
nance. The results of fume 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.
OPENING THE DOOR
− Make sure that the top safety bolts (2) and bottom safety
bolts (3) on the hinged side of the boiler are tight;
− completely unscrew the main xing bolts (1) and open
the door (these bolts are captive in the door and cannot
be removed).
