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
flow pipe as illustrated
| 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 65 - 80°C flow temperature, the boiler should either maintain
maximum flow temperature (65 - 80°C) or shut down, without F20 (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 F20 appears CLICK HERE.
