What is the stack constructed of and what is the chance of the stack catching on fire?
Our stacks are constructed from steel plate and are fully lined with 3″ of insulating castable material capable of withstanding temperatures in excess of 2500 degrees. Stacks on cremation equipment do not catch on fire like fireplace chimneys, as no creosote is present in the cremation process after the secondary burning process. However, some manufacturers attempt to use unlined stacks with air-cooling. Under certain conditions the temperature inside the stack can rise to a point where combustion of certain construction materials can begin causing a building fire.
