John Wood Power Direct Vent (ENERGY STAR) - Manual (Page 15)

Before plugging in the water heater, always make sure:
•
The voltage and frequency correspond to that specified
on the water heater wiring diagram.
•
The electrical outlet has the proper overload fuse or
breaker protection.
•
Fill the tank with water and check all connections for
leaks. Open the nearest hot water faucet and let it run
for 3 minutes to purge the water lines of air and sediment
and to ensure complete filling of the tank. The electrical
power may then be turned on. Verify proper operation
after servicing.
Note: Always reference the wiring diagram for the correct
electrical connections.
