e:: All venting installations shall be in accordance with the latest edition of “Part 7, Venting of
Equipment of the National Fuel Gas Code, ANSI Z223.1 (NFPA 54), or applicable provisions
of local building codes”.
Natural venting models are equipped with a vent cap designed for natural venting. Air for
combustion enters at the base of the vent through a protective grille, and the design of the vent
cap is such that the products of combustion are discharged at the upper section of the cap. The
cap is shipped in a separate carton. It should be fastened in position as shown in the
Vent Cap
Assembly
figure below, and should not be altered in any way.
