We moved into a property in early spring and the living room has an old fashioned gas fire. We’re renting and know everything has been properly checked as we actually viewed while the engineer was here. I’ve just switched the fire on for the first time after a lot of fiddling and it really smells! Not of gas but just a faintly, hot things burning kind of smell. I’m assuming (hoping) that this is just because it’s not been used for a while and is probably a bit dusty inside? Is it still safe to use? Is there anything I can do to get rid of the smell or will I just have to keep it in til it stops? Picture of the ugly beast so you know what I’m talking about
