•
Check proper boiler lighting by doing several tests, turning it on and off with the room thermostat or remote control.
•
Using a combustion analyser connected to the boiler fume outlet, check that the CO
boiler operating at max. and min. output, corresponds to that given in the technical data table for the corresponding
type of gas.
•
Make sure the fuel consumption indicated on the meter matches that given in the technical data table on sec. 4.4.
•
Check the correct programming of the parameters and carry out any necessary customization (compensation curve,
power, temperatures, etc.).
3.3 Maintenance
IMPORTANT
ALL MAINTENANCE WORK AND REPLACEMENTS MUST BE CARRIED OUT
B
BY SKILLED QUALIFIED PERSONNEL.
Before carrying out any operation inside the boiler, disconnect the power
and close the gas cock upstream. Otherwise there may be a danger of explo-
sion, electric shock, suffocation or poisoning.
Periodical check
To ensure lasting proper operation of the unit, it is necessary to have an annual inspection carried out by qualified per-
sonnel, providing for the following:
•
Heat exchanger check and cleaning with suitable products if dirty or clogged.
The exchanger can be cleaned only when its temperature is under 40°C.
Clean only with suitable products approved by the manufacturer, e.g.:
ALU CLEANGEL
BIO HALL LIQUID
•
Check and cleaning (if necessary) of burner (do not use chemical products or wire brushes).
•
Check and cleaning of electrodes, which must be free of deposits and properly positioned.
•
Check of gaskets and seals (burner, sealed chamber, etc.).
•
Check and cleaning of sludge remover filters and system filters.
•
Check, cleaning and filling of condensate drain traps.
•
Check of wiring, contacts, electrical actuators.
•
Check and cleaning of generator air inlets and boiler room air intakes.
•
Check and cleaning of fume evacuation duct-manifold-flue system.
•
Check of expansion tank and precharge.
•
Check of correct and stable system water pressure, ensuring conformity with the required working pressure.
The use of automatic filling systems for reinstatement of operating conditions
B
must provide for adequate treatment of the water (ref. )
•
check of heating system water chemical and physical parameters (ref. )
•
water and gas system tightness check
•
check of correct and stable gas supply pressure to the plant (20 mbar for operation with natural gas); any fluctuations
or pressure drops below the declared value can create malfunctioning and stops with need for manual resetting.
•
check of correct burner ignition and operation of control and safety devices (gas valve, flow meter, thermostats, etc.)
•
check of circulating pump operation, freeing them when necessary
•
fume analysis and check of combustion parameters
The boiler casing, control panel and aesthetic parts can be cleaned with a damp, soft cloth, if necessary
A
soaked in soapy water. Do not use abrasive detergents and solvents.
