This  appliance  has  been  design  certified  as  complying  with
American National Standard/CSA Standard for water heaters and
is considered suitable for:
Water  (Potable)  Heating  and  Space  Heating: All  models  are
considered suitable for water (potable) heating and space heating.
HOTTER WATER CAN SCALD: 
Water heaters are intended to produce hot water. Water heated
to  a  temperature  which  will  satisfy  space  heating,  clothes
washing,  dish  washing,  and  other  sanitizing  needs  can  scald
and permanently injure you upon contact. Some people are more
likely to be permanently injured by hot water than others. These
include the elderly, children, and the physically or developmentally
disabled. If anyone using hot water from this heater fits into one
of these groups or if there is a local code or state law requiring
a certain temperature water at the hot water tap, then you must
take special precautions. In addition to using the lowest possible
temperature setting that satisfies your hot water needs, a means
such  as  a  Mixing  Valve,  should  be  used  at  the  hot  water  taps
used by these people or at the water heater, see Figure 2. Mixing
valves  are  available  at  plumbing  supply  or  hardware  stores.
Consult  a  Qualified  Installer  or  Service Agency.  Follow  mixing
valve  manufacturer’s  instructions  for  installation  of  the  valves.
Before changing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual.
  * the side recirculation loop connections may not be used as the primary water inlet and outlet connections. for your convenience, plugs are installed 
in these fittings at the factory. Remove these plugs if needed for your specific installation. Otherwise (as with all connections) check for leaks while 
filling the tank with water and after completing the installation.
