Mains Power On
pipes close to the heat exchanger
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Allow boiler and system to heat, watching the temperature on the FGA.
The temperature should heat to approximately 80°C (or whatever MAX flow temp is set to).
The differential should be approx. 20°C or less.
The boiler should reach this temperature without cutting out on the overheat.
It should also shut the burner down when the temperature is reached.
