Observation:
Allow the burner to ignite and the boiler to start to heat the radiators, measure the temperature differential between the flow and return pipes to the primary heat exchanger.
Expect a differential of approximately 25°C or less.
Is the temperature differential as expected?
Note:
The differential measured on initial firing may be slightly higher, also this appliance can take a significant time to ramp up, only select an outcome on this test once the appliance has ramped up.
