Customer Questions & Answers

If i did use this liner for oil burner what are the hazards

Asked by: Brian
I don;t want to be overly dramatic, but the potential hazard is death. When you burn home heating oil, AKA #2 oil, one of the bi-products of combustion is acid and at times water. This is another way of saying sulfuric acid. Within roughly six months the acid will eat major holes in the aluminum and the liner will be compromised. Flue gas will then have a path into places where it should not go. Flue gas will cause carbon monoxide poisoning. Further eventually the liner will break apart into pieces that could block the chimney. Bottom line is that you should not use aluminum on oil under any circumstances. It is not just a minor technicality. Don't do it and if you have remove it immediately. Carbon monoxide kills hundreds of people a year. As equipment becomes more efficient the danger grows, which is why we line chimneys to begin with. Don;t put yourself at risk by underestimating the danger.

Asked by: haleylu
No you can not use aluminum liners to vent an oil appliance. The flue gas temperature is to hot. For oil you need to use stainless steel.
