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.
