Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
CH Demand
Attach temperature clamp to primary heat exchanger
flow pipe as illustrated
Note:
Ensure a good connection is made with the flow pipe
or mis-diagnosis will occur

| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Allow the appliance to ignite and run for central heating.
Observe the flow temperature.
At approximately 75 - 80°C flow temperature, the boiler should either maintain
temperature or shut down, without overheat fault code appearing.
Note.
1. To speed up this test, reduce the heating circuit by turning off some radiators.
2. If a fault code other than overheat appears CLICK HERE.
BOILER MAINTAINED AND/OR SHUT DOWN AT APPROX 75 - 80°C - OVERHEAT DID NOT OCCUR - CLICK HERE
BOILER GOES TO OVERHEAT - TEMPERATURE BELOW 80°C - CLICK HERE
BOILER FLOW TEMPERATURE EXCEEDS 88°C AND BOILER STILL FIRED - CLICK HERE
