Have just had new Faber serene fire installed in purpose built false chimney breast acc. to manufacturers specification. Heat convects into room from top of firebox but also heats the top edge of metal surround and wall for about 10" above fire. I would prefer to wallpaper the chimney breast & not paint it but fear that the wallpaper will not stick properly and will curl up at the edges when the fire is in use. Are there any tricks of the trade that i need to know? How come all the magazines show wallpaper in these modern show homes? Do they never put the fire on?
