8. MAINTENANCE AND CLEANING
The following operations are to be performed by qualified personnel only.
8.01 Seasonal inspection of the boiler and flue
Before the beginning of winter you should perform a general inspection of the boiler, heating system
and flue. The inspection should verify:
That the boiler flueways, burner and flue are clean.
That the water in the system is at the correct pressure – or correct level in the case of an open system.
That all control and safety devices operate properly.
That the probeand spark electrode are free of carbon deposits.
That the pilot flame correctly aligns with the probe.
That circulation pumps are free running.
That there are no gas leaks.
That the gas flow rate and pressure are correct.
That the pressure in the expansion vessel is as indicated in table 3 (paragraph 2.02).
8.02 Cleaning the boiler and the flue
To clean the boiler and the flue, remove the burner bars from the combustion chamber.
For access to the cast-iron exchanger, proceed as follows (fig. 10): Remove the cover of the casing
secured by slot pins; pull out the insulation covering the draft diverter, remove the smoke-box
inspection cover 2 and its insulation, secured with self-threading screws 1.
Now you may clean all the smoke passages in the boiler using a pipe brush 3. Remember you should
check and if necessary clean the flue and its connection to the boiler. Be careful not to damage the Flue
gas safety thermostat phial or capillary.
Important - Do not clean the burners with chemicals or a steel
brush, as these might change the air-gas mixture outlet holes.
When cleaning is complete, re-assemble carefully and in the
correct position. Then check the seal along the gas and smoke
circuits, functioning of the control and safety devices and gas
pressure and rate of flow.
