PREMIER E SERIES DUAL CAPACITY INSTALLATION AND MAINTENANCE MANUAL
WATER TANK PREPARATION
A family of four should have a water heater with a minimum 50-gallon capacity. For families of
more than four, use an 80-gallon water heater or two 50-gallon water heaters connected in a series as
shown in Figure 12 on page 11. Electric water heaters are recommended.
CAUTION:
Elements will burn out if energized dry.
1) Turn off the power to the water heater.
2) Attach a water hose to the water tank drain connection and run the other end of the hose to an
open drain or outdoors.
3) Close the cold water inlet valve to the water heater tank.
4) Drain the tank by opening the valve on the bottom of the tank, then open the pressure relief valve
or hot water faucet.
5) Flush the tank by opening the cold water inlet valve to the water heater to free the tank of
sediments. Close when draining water is clear.
6) Disconnect the garden hose and remove the drain valve from the water heater.
