The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to
ensure that (1) no one is in front of or around the outlet of the
temperature-pressure relief valve discharge line, and (2) 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, the tank must be filled with
water. Water must flow from the hot water faucet before turning
“ON” gas to the water heater.
To fill the water heater with water:
• 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.
• 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.
• 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.
• Check all water piping and connections for leaks. Repair
as needed.
Wiring
USE WITH POWER CORD
The water heater comes equipped with a 7 foot power cord
which can be used to connect to a 110/120 volt power source if,
(1) local codes allow, and (2) there is a three prong grounded
receptacle available. This unit must have a grounded outlet to
operate.
FIGURE 25.
You must provide all wiring, (1) to a receptacle or, (2) between
the water heater and junction box when power cord is not used.
Do not use an extension cord. If there is not a suitable
receptacle and/or local codes prohibit use of a power cord,
field wiring must be provided.
If you are not familiar with electric codes and practices, or if you
have any doubt in your ability to connect the wiring to this water
heater, obtain the service of a competent electrician or contact
your local electric utility.
If wiring from the fuse box or circuit breaker box was aluminum
for the old water heater, replace it with copper wire. If you wish
to reuse the existing aluminum wire, have the connection at
the water heater made by competent electrician. Contact a local
electrical contractor and/or the local electric utility.
