hi all thanks for the replys
only reason i/we need it out as the only thing it dos is keep the birds warm on the chimmey ,, the chimmey seens to all sealed and the house is only 45 years old and for 23 of them year iv lived here in this house with gas but gas was fitted in these houses around 35 years ago as i lived in the street when the council did them ,so the chimmey has had very little use ,heat wise v look at the chimmey via the loft and all has been seal with new plaster , and shows no signs of cracks ,, so the flue that is in is a gas flue which needs to be remove .. ,, iv had my head up the chimmey dirty job ,,and all looks good ,so am going to put a smoke bomb up it a and see what happends ,.i v red that i may not need a flue in the chimmey if its all sealed .. am i reet in thinking that i may just chuck thelog burner in with the pipe and plate ,, this log burner is only for heating the living room as its 35 ft long and 20 wide and NOT to heat water or work rads ,, and will be only used every now and again , and never to be left on all night . and yes i love a living flame been old school
