This gas water heater requires an adequate source of clean air for combustion and
ventilation. Without sufficient air, your water heater may not operate properly and
may emit excessive and abnormal amounts of carbon monoxide which may result in
carbon monoxide poisoning or death.
WARNING
The guidelines in this section apply to installations within the United States. All
U.S. installations must conform to the National Fuel Gas Code, ANSI Z223.1/NFPA
54 (current edition) and local codes.
Canadian requirements differ from the guidelines in this section. In Canada,
follow the requirements of B149.1 (Natural Gas and Propane Installation Code,
current edition) as well as local and provincial codes. Contact your local code
enforcement agency for direction.
NOTICE
Before installing the water heater, you must determine the amount of air needed to supply this water
