AWARNING
A gas water heater cannot operate property without the cor*
rect amount of air for combustion. Do not install in a confined
area such a closet, unless you provide air as shown in the
“Locating The New Water Heater“ section. Never obstruct

The New Witer Heater” section of this manual and also the
latest edition of the National Fuel Gas Code, ANSI Z123.I, also
referred to as NFPA 54 for specifics provided concerning air
required.
