System Maintenance; Servicing Schedule - IDEAL Viceroy GT 8 Installation And Servicing

61 SYSTEM MAINTENANCE

Water Level
Check the water level in the installation regularly and if
necessary top it up without allowing a sudden inlet of cold
water into the hot boiler.
The operation should only be necessary a few times per
season; if it has to be done more frequently, there is probably
a leak which should be found and corrected without delay.
62 SAFETY
For boilers with gas burners:
It is the law that any service work must be carried out by a
registered CORGI installer.
WARNING. Always turn off the gas supply at the gas service
cock, switch off and disconnect the electricity supply to the
appliance and any external controls before servicing.
IMPORTANT. After completing the servicing or replacement of
components always:
• Test for gas soundness.

INSTALLATION
Safety Devices
Check that safety devices, particularly the heating circuit safety
valve, are working correctly at regular intervals and at least when
the boiler is cleaned.
Draining
It is recommended that the installation should not be emptied
unless absolutely necessary.
For example: when leaving for several months and/or there is a
risk of frost in the building.
• check the water system is correctly filled and free of air. Air
in the boiler could cause damage to the heat exchanger.
• With the system hot examine all water connections for
soundness.
• Check the gas rate and measure the combustion CO/CO
content.
• Complete the boiler log book.
• Carry out functional checks as appropriate.
3. Optional test for gas fired boilers - Connect a suitable gas
analyser to the sampling point fitted in the flue adapter. For
correct boiler operation the CO/CO2 ratio of the flue gas
should not be greater than 0.004 ratio. If this is the case
and the gas input is at least 90% of the nominal, no further
action need be taken. If not proceed to 4.
4. Remove and clean the burner.
5. Inspect the heat exchanger through the burner opening.
Clean the flueways.
6. Check that the flue terminal is unobstructed and that the
flue system is sealed correctly.
7. After completion of servicing refer to previous frame for
reference to final safety checks.
