*Typical  flow  rates  are  based  on  40  PSI  to  the  home  and  faucets  with  standard  flow  restrictors.  Higher  PSI  and 
unrestricted faucets may result in higher flow rates, which may result in a maximum temperature increase of 72ºF.
**Incoming flow rates lower than 1 GPM through the water heater, or incoming water temperatures higher than 80ºF, 
may result in water heating to higher than its set point. Avoid scalds!! Always test the water with your hand before using it 
to be sure that cold water doesn't need to be mixed in first.
