Hi, I have an ideal classic ff230 and this evening when the heating came on I noticed a rather loud whining noise coming from the boiler near the top and when I looked in the little inspection window, the flames were yellow rather than blue, so I have immediately turned it off and phoned the landlord and am waiting for him to get back to me, I'm now worried about how long this has been going on for and are we at risk from carbon dioxide? (we have an alarm which hasn't gone off) or as its all sealed would it all just go out the flue?
Thanks.
Carlos.
