•Certifications/approvals
Underwriters Laboratories has certified this burner to comply with ANSI/UL 296 and has listed it for use with #1 or #2 fuel oil as specified in ASTM D396. Low sulfur #1 and #2 fuel oils reduce heat exchanger deposits with all burners compared to the standard fuels. Reduced deposits extend the service interval for cleaning and improve the effi- ciency of the appliance over time. Low sulfur fuels reduce particulate and oxides of nitrogen emis- sions as well. The Oilheat Manufacturers’ Associa- tion recommends these fuels as the preferred fuels for this burner.
