Section 2G-2 specifies requirements for provision of combustion and ventilation air for one-pipe installations. Section 2G-3 covers two-pipe installation. An important consideration in selecting one or two pipe installation is the quality of the combustion air. Indoor air is sometimes contaminated with vari
