The Direct-Temp for multifuel stoves (DT-M) is a unique venting system designed to address the problem of highly corrosive flue gases produced by burning corn or other biofuels. The DT-M converts any conventional corn-burning or multifuel stove into a direct-vent system. The DT-M comes with a full array of parts that meet or exceed appliance manufacturers’ recommendations.
