please help before i light it ???
we bought a house with a normal gas fire in the lounge - now its getting colder I want to light it but decided to remove the coals to have a hoover up of old dust etc first and saw what looks like a thick layer of cotton wool under the coals !!!
Is this normal and okay to light
Its a Jetmaster gas fire with a gas pipe going in and a knob underneath saying OFF PILOT and HIGH as the 3 options
