Wood or gas fire pits should not be placed on top of Trex decking. However, gas fire pits may be installed beside or between deck boards with a protective wall made of stone or other fire-resistant material used for insulation.
Wood burning fire pits should not be placed on top of Trex decking unless installed with DeckProtect, a product designed to temper extreme heat and loose embers. For more information, please visit their website.
