good luck with that, unless you know them!
The chances are that its actually faulty!
Why?
In that case unless it was disclosed to you during the conveyancing process the seller has the responsibility for paying to have it fixed.
Only if the qustion regarding satisfactory operation was asked by the buyers solicitor (or unlkess you live in scotland, apparently)
If you are satisfied that you have set it correctly and the seller is not available to ask then it would be a good idea to get a competent boiler engineer to come and service it and repair it if necessary.
Tony, she isn't satisfied that she knows waht she is doing, hence the question.
Do you have a gas cooker? If so who fitted that?
Why, Tony, you gonna offer to fit it for £84?
poigirl,
Generaklly, don't listen to Tony's ramblings. setting a boiler is normally easy, but on top of everything else you have to do, when you move to a new home, it can be tiresome, and apparently daunting.
I am not familiar with that boiler, but Tony did raise one good point. I always advice folk moving into a new home to get the gas checked out, unless you KNOW it has been done alread. You won't know the history, and, espedially if you have open flued appliances, gas fires etc, there can be danger lurking. I am not trying to be a scaremonger, but it is a serious issue.
Is this your boiler. This is the user manual, that I hope you will find useful.

Good luck in your new home.
And remember to buy a new gas fire from a "proper" shop
