John Wood POWER VENTED GAS FIRED WATER HEATER Installation And Operating Instructions Manual page 20

•
Ensure that the water heater and the outlet are properly
grounded. Failure to properly ground the heater can pre-
vent the unit from operating.
•
Ensure that the water heater is installed in accor-
dance with prevailing provisions of the latest edition of
"Canadian Electrical Code (CAN/CSA C22.1), Part I".
Before applying power to 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. If all the steps
in the "Installation Checklist" have been completed, the
electrical power may be turned on. Verify proper opera-
tion after servicing.
Note: Always reference the wiring diagram for the correct
electrical connections.
WARNING
When the unit is plugged in, 120VAC is pres-
ent at the electric connections of the gas
control/thermostat.
