WARNINGS
ATTENTION
All maintenance operations must be
performed by qualified staff and authorized by
RADIANT BRUCIATORI spa.
WARNING
The maintenance operations must be
performed once every twelve months starting from
the boiler installation date.
WARNING
To ensure longer life span and proper
operation of the device, during the maintenance
operations use only original spare parts.
DANGER
Before each components cleaning or
replacement operation, ALWAYS cut off the POWER,
WATER and GAS supply of the boiler.
Please perform the following operations once a year:
› check the pre-load pressure of the expansion tank;
› check the sealing of the water components, and
replace the gaskets if necessary;
› check that the wiring is installed in compliance with
the requirements in the boiler instruction manual;
› check the wiring inside the control panel;
› remove and clean the burner from oxidation;
› check the integrity and the position of the sealed
chamber sealing gasket;
› check the primary exchanger, if necessary, clean
it;
› check the operation of the gas burner start up
and safety systems. If necessary, remove and
clean the flame detection and start up electrodes
from incrustations paying attention to respect the
distances with respect to the burner;
› check the sealing of the gas components, and
replace the gaskets if necessary;
› visually check the flame and the condition of the
combustion chamber;
› if necessary make sure that the combustion is
adjusted correctly and if required proceed as
indicated in section 2.1.3 “CO2 VALUE CHECK AND
CALIBRATION”;
› periodically check the integrity of the venting
system for safety and proper operation;
› make sure that the permanent ventilation outlets
are present, correctly sized and functioning, based
on the in-stalled devices. Follow the requirements
provided by Local and National legislation;
› check the heating circuit safety systems: limit
temperature safety thermostat; limit pressure
safety;
› check the proper operation of the condensate
draining system, including the devices outside
the boiler such as condensate collection
devices installed along the path of the venting or
neutralization devices for acid conden-sate. Check
that the liquid flow is not obstructed and that there
is on combustion gas build up inside the internal
sy-stem;
› check the flow and temperature of domestic hot
water.
