Installation
water in sufficient quantities, should circumstances demand, to prevent bodily injury, hazard to life, or property
damage. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause
property damage.
THE DISCHARGE PIPE:
• Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other
restrictions.
• Shall not be plugged or blocked.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the
discharge pipe.
• Shall terminate at an adequate drain or external to the building or structure.
• Shall not have any shut-off valve between the relief valve and tank nor in the discharge pipe.
The temperature-pressure relief valve must be manually operated at least once a year. Caution should be
taken to ensure that no one is in front of or around the outlet of the temperature-pressure relief valve discharge
line, and the water manually discharged will not cause any bodily injury or property damage because the water
may be extremely hot.
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. Open the cold water supply valve to the water heater. The cold water supply valve must be left open when
the water heater Is In use.
2. To ensure 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.
3. Check all water piping and connections for leaks. Repair as needed.
4. Never alter or modify the certified construction of the water heater or its components, or bypass any safety
features. Doing so voids all warranties.
WIRING
Never use the water heater unless it is completely full of water. To prevent damage to the tank and the heating
element, the tank must be filled with water. Water must flow from the hot water faucet before turning on the
power.
