exhaust required by fireplaces, gas furnaces, gas water
heaters and other naturally vented systems. To minimize the
chance of interruption of such naturally vented systems, follow
the heating equipment manufacturer’s guidelines and safety
standards such as those published by NFPA and ASHRAE.
When applicable, install any makeup (replacement) air system
