DIY book for oil fired combi central heating boiler

[Pirateboy]

After a few failed attempts to find a good central heating Engineer to service my oil fired combi central heating boiler (it's an HRM 25/19) I have decided that I may as well get a good book and have a go myself. Can anyone recommend a good publication?

Cheers, Tony.

Who were the boiler engineers who you decided were not good?
