we had the fire serviced and it failed the smoke match test as some came back in the lounge...............all the doors and windows were shut and most of it went up the flue..but every so often a bit came back .now conditions outside were blowing a severe wind off and on. so he now tells me i need a rotovent to sort it out .the houses have been here 20 years and no one else has got one fitted.........maybe no one else has had their gas fire serviced i don't know.i am being told that he should have done the test with the doors or windows open as well to see if it was just a lack of ventilation? anyway he has disconnected my fire and sort of capped it off.i mean if i turn the gas supply on it will come out of the bit he has supposedly capped. is something not right with the test or is it all correct,they did not try to sell me a rotovent ,just said he rang his boss and he told him thats the answer........he his corgi registered as i saw his id .......................any offers of advice or indeed anything would be greatly appreciated.
