The Rivelin 24kw burner is constructed from stainless steel and available in both a Natural Gas and LPG version. The burner is pre-aerated, producing a clean burning flame on both LPG (propane) and Natural Gas. The LPG burner comes in 2 variations, an 18kw output or a 22 Kw output. The 18kw burner requires a 19 Kg LPG, propane bottle whereas the 22kw LPG burner requires a 47kg gas bottle. It is important to note this to safely deliver the required gas flow, ensuring the regulator does not freeze over extended usage periods. The gas bottle cannot be fitted below the fire table, and is normally housed away from the fire table and piped into the burner beneath the decking or floor.
