AFTER TIGHTENING BOTH FITTINGS AT THE WATER HEATER, PRIOR TO TURNING ON THE
POWER OF THE WATER HEATER, OPEN SEVERAL HOT WATER FAUCETS AND ALLOW WATER

air from the water lines and the heater.

Shower (1.5 gpm) ― Sink Faucet (1.0 gpm) - All data above are based on water leaving temperature 105º F (40º C). 1.5 gpm showerhead flow rate;
1.0 gpm sink faucet flow rate, and adequate water pressure @ 60 psi. Actual performance may be altered by variations from these parameters.
For voltages less than 240 V the heating capacities will vary and it would be necessary to consider a higher capacity model.
