I am posting this topic as a warning to unsuspecting customers considering buying a wall hung flueless gas fire. I recently bought such a fire , a contemporary design which has a glass front with a line of flame inside. Being flueless it hangs directly on a wall. When fitted I was delighted with the product. Then I turned it on. What I hadn't realised was that these fires have a convector grill on the top edge which emits hot/ warm air. The problem was that the hot air heated the plaster skimmed wall to such an extent that an area of plaster about three foot above the fire bellied out, cracked and literally fell off the wall. To be fair the instructions do say not to hang below a TV, picture frame etc but I hadn't realised it would affect the actual wall in this way. I would suggest that you read my query, and the responses I received, on this subject before deciding to buy one yourself. My advice would be DON'T !!! but I would be interested in any views from retailers or fitters of this type of fire.
