I need some advice please I have a Keston Celsius 25 boiler and over the last couple of months it has started blowing out gas when it shuts down. I have had the gas engineer out twice and first time he replaced the gas seals but it didn't seem to make any difference and then 2nd time he couldn't smell anything wrong. The boiler is fine when it's on and after it's gone off so there's no constant gas leak. However, a couple of minutes after it has just shut down I can smell gas it's like it blows it out at the end. Is this normal for a Keston?
