General Information continued-
This water heater has been manufactured for operation at altitudes from sea 
level to 2000 feet (610m) (unless otherwise specified on the water heater). 
For use of this appliance at an elevation greater than 2000 feet (610m), contact 
the dealer or manufacturer listed on the rating plate for information on any 
necessary modification. Uncorrected operation of this appliance may create a 
hazard to life and property. 
Make sure to check the rating plate and combination gas control on the water 
heater to be certain that the type of gas being supplied corresponds with the 
marking on the rating plate and combination gas control. 
A sacrificial anode is used to extend tank life. The removal of this anode, for 
any reason, will nullify the warranty. In areas where water is unusually active, 
an odor may occur at the hot water faucet due to a reaction between the 
sacrificial anode and the impurities in the water. If this should happen, an 
alternative anode may be purchased from the supplier that installed this water 
heater. This will minimize the odor while protecting the tank. Additionally, the 
water heater should be flushed with appropriate dissolvers to eliminate any 
bacteria. 
INSTALLATION
Locating the Water Heater
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. 
The location of this water heater is of the utmost importance. Before installing 
this water heater, read the Installation section of these instructions. 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
.
DANGER

corrosive vapors and liquids in the vicinity of this or any other 
appliance.
