TYPE B-VENT INSTALLATION (Listed B-0 or Greater)
Before beginning installation be sure that the overall height and gas vent size conform to building code requirements. Gas vents extending
through pitched roofs can extend a minimum height of at least 600 mm (2') higher than any obstruction within 3m (10'). Gas vents extending through flat roofs are required to extend at least 600 mm (2') above the roof and at least 600 mm (2') higher than any portion of the building or adjoining building within 3m (10') of the gas vent.
•In absence of local codes, follow Section 7.0 of the current Na- tional Fuel Gas Code NFPA 54/ANSI Z223.1 and the Natural Gas Installation Code - vent sizings for Category I systems us- ing double wall

•Situate the gas vent in the structure so that it can be installed without cutting joists, sills, plates, or major load bearing parti- tions or members. It is also important to locate the base of the gas vent as near as possible to the heating appliance.
•This burner system must be properly connected to a venting system. This burner system is equipped with a vent safety shutoff system.
•Use only vents labeled "FOR EXTERIOR USE" above the roofline.
•Consult the authority having jurisdiction to select the correct gas vent diameter. Avoid using a larger than necessary diameter.
