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 75 - 82°C flow temperature, the boiler should either maintain
maximum flow temperature (75 - 82°C) or shut down, without the overheat fault code appearing.
Note:
To speed up this test you may wish to reduce the heating circuit by turning off some radiators.
