Initial Observations: What We Look For First
Before touching any appliance, we'll perform a visual sweep. We're looking for common indicators of potential issues that might be immediately obvious. This includes checking for visible sooting or staining around an appliance, which often points to incomplete combustion. We also inspect the flame itself – a lazy, yellow flame on an atmospheric burner is a red flag, as opposed to a crisp blue flame. Ventilation is crucial; any alterations or blockages in the room where a boiler is installed can be problematic. We also check the flue's route, especially if building work or an extension has recently occurred, as this can easily compromise its integrity.

- Yellow, lazy flames instead of blue
- Blocked or altered appliance ventilation
- Flue path disturbed by recent building work
