Why a Liner is Essential
Oil vs. Gas Exhaust — Why Your Old Flue Won’t Work
Oil combustion produces hot exhaust that rises quickly and dries out residues as it goes. Gas combustion produces cooler, wetter exhaust that condenses on the flue walls — creating acidic liquid that rapidly destroys clay tile liners.
