evening everyone, First time poster here. Have always had oil heating but this is a first for me. Moved into a new house 3 months ago with a Camray 5 oil boiler installed on it. Not one issue with it. I filled my tank this week (there was still 150 litre left in it) and since then there is a smell of oil from round the boiler. I have checked and round the burner is dry, no drops etc. I took out a drawer beside the boiler and the smell seems to be coming from this pipe. Any pointers as what that pipe is and what could be causing the smell? Thabks in advance.
