Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
CH Demand
Attach temperature clamp to the flow pipe as indicated by the red arrow
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Allow the boiler to ignite and run on central heating operation.
Turn the temperature control to the maximum position - approximately 80°C.
If the flow temperature is already at 80°C or above the boiler should either maintain flow temperature or shut down, if flow temperature is below 80°C the boiler should continue to increase flow temperature to approximately 80°C then either maintain the flow temperature or shut down, without overheat occurring.
Note:
To reduce the time taken for this test, reduce the heating circuit by turning off some radiators.
