If after manually operating the valve, it fails to completely reset and
continues to release water, immediately close the cold water inlet to
the water heater, follow the draining instructions, and replace the
temperature-pressure relief valve with a new one.
FILLING THE WATER HEATER
Never use this water heater unless it is completely full of
water. To prevent damage to the tank and heating element,
the tank must be filled with water. Water must flow from the
hot water faucet before turning “ON” electrical supply to the
water heater. The manufacturer will not warrant any elements
damaged by failure to follow instructions.
To fill the water heater with water:
1. Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
2. Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
3. To insure complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run
until a constant flow is obtained. This will let air out of the
water heater and the piping.
4. Check all water piping and connections for leaks. Repair
as needed.
5. Never alter or modify the certified construction of the water
heater or its components, or bypass any safety features.
Doing so voids all warranties.
T&P VALVE and PIPE INSULATION
(On Selected Models)
Remove insulation for T&P Valve and pipe connections from carton.
Fit pipe insulation over the incoming cold water line and the hot water
line. Make sure that the insulation is against the top cover of the heater.
Fit T&P Valve insulation over valve. Make sure that the insulation
does not interfere with the lever or outlet of the T&P valve.
Secure all insulation using tape.
