Section 4 VENTING

This appliance is certified under the ANS/CSA Standard for Vented Gas-Fired Space Heating Appliances. In accordance with these standards all sidewall venting must conform to the supplied diagram for Vent Terminal Clearances, which are stated for both U.S. and Canadian installations. These clearances should be compared to but not less than those specified in the current ANSI Z223.1/NFPA 54, National Fuel Gas Code, or CSA B149.1, Natural Gas and Propane Installation Code. Clearances not covered in the table or above listed codes must comply with local installation codes and the requirements of your local gas supplier.
