My chimney has not been used for several years and i wish to use it again by fitting a gas fire heater. Can someone tell me which type of gas cowl i require for my chimney. As you can see from the picture, current cowl insert is a Hood Top, i have been told this is incorrect for gas fuel heaters. Went to my local building merchants and they said they do stock gas cowls but were not in a position to give advice which type of cowls to use as this is something a gas safe engineer can only give advise. But they did mention DFE gas cowl flue terminal 225mm and Insert Terminals GC2 / GC5 external dia 205mm
Can someone please explain to me which one would be suited for my setup.
Thanks
