GUARANTEE LIMITATION - IMPORTANT INFORMATION
All 316 stainless steel products, although having very high corrosion resistance, are at risk when
exposed to relatively high sulphur content fuels, such as processed coal products (smokeless fuels),
particularly if the appliance can be left burning all night. When the appliance is under-fired, the flue
gas temperature is low, and excessive condensation can result. This level of condensation and high sulphur
content fuel residue can very quickly destroy even the best quality twin wall liner. Your installer will
advise on which products to avoid.
