I was getting a knock sound (not very loud but slightly undesirable at night) a couple of minutes after the (warm air) boiler switched off. Found it was from where the flue enters the loft - one side of the flue was knocking against the hole in the ceiling.
Wedging (with a piece of wood) the flue from the opposite side so that the flue was in contact the ceiling, successfully stopped the knocking. However, I am wondering if this is a good idea, or if there should always be a gap. Is there something better I should use to fill the gap?
Also the majority of the flue is insulated and wire caged but a couple of inches off the ceiling is not insulated. Is it safe for normal loft insulation to come in contact with the flue at this point?
