INSTALLATION
Locating the Water Heater
WARNING
Water heaters are heat producing appliances. To avoid damage or injury, 
there must be no materials stored against the water heater or vent-air intake 
system, and proper care must be taken to avoid unnecessary contact, 
especially by children, with the water heater and vent-air intake components. 
UNDER NO CIRCUMSTANCES SHALL FLAMMABLE MATERIALS SUCH 
AS GASOLINE OR PAINT THINNER BE USED OR STORED IN THE 
VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN 
ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER 
HEATER OR VENT-AIR INTAKE SYSTEM. 
 
This water heater must NOT be installed in any location where gasoline or 
flammable vapors are likely to be present, unless the installation is such to 
eliminate the probable ignition of gasoline or flammable vapors. 
Water heaters in residential garages must be installed and located, or 
protected, to avoid physical damage. For other installations refer to local 
codes. In the absence of local codes, the water heater must be installed in 
compliance with the National Fuel Gas Code, ANSI Z223.1- Latest Edition, or 
in Canada, Natural Gas Installation Code, CAN/CGA B149.1-Latest Edition, or 
Propane Installation Code, CAN/CGA B149.2-Latest Edition. 
The location of this water heater is of the utmost importance. Before installing 
this water heater, read the Installation section of these instructions. After 
reading these Installation and Operation Instructions, select a location for the 
water heater where the floor is level and is easily accessible to gas and water 
supply lines. DO NOT locate the water heater where water lines could be 
subjected to freezing temperatures. Make sure the cold water pipes are not 
located directly above the gas control, so that condensate during humid 
weather does not drip on the controls. 
This water heater MUST be installed indoors out of the wind and weather.
To comply with NSF requirements, this water heater is to be:
a) Sealed to the floor with sealant, in a smooth and easily cleanable
way, or;
b) Installed with an optional leg kit that includes legs and/or extensions
that provide a minimum clearance of 6” beneath the water heater.
