Water Supply Connections Continued....
In regards to the HOT WATER OUTLET:
• Connections between the water heater and point(s) of use should
be as short and direct as possible.
• DO NOT use lead or non-approved plastic pipe.
• To conserve energy and minimize heat loss, insulation of hot
water piping is recommended.
NOTICE: The ow rate of hot water may vary when more than two
faucets (appliances, xtures, etc.) are being used simultaneously.
NOTICE: The pipes MUST be completely drainable. If the hot water
faucets are located at a point higher than the water heater, place a
drain valve at the lowest point (see diagram to the left).
A new pressure relief valve, complying with the Standard for relief Valves and Automatic Gas Shut-Off Devices
for Hot Water Supply Systems, ANSI Z21.22, must be installed at the hot water outlet connection of the water
heater at the time of installation. Local codes shall govern the installation of relief valves.
For safe operation of the water heater, be sure that:
• The pressure rating of the relief valve must not exceed 150 psi, the maximum working pressure of the water
heater as marked on the rating plate.
• The BTUH rating of the relief valve must equal or exceed the BTUH input of the water heater as marked on its
rating plate.
• No valve of any type should be installed between the relief valve and the water heater.
• Discharge from the relief valve should be piped to a suitable drain to eliminate potential water damage. Piping
used should be of a type approved for the distribution of hot water.
• Hot and cold water lines should be insulated up to the water heater.
• The discharge line must be NO SMALLER than the outlet of the valve and must pitch downward to allow
complete drainage (by gravity) of the relief valve and discharge line.
• The end of the discharge line should not be threaded or concealed and should be protected from freezing. No
valve of any type, restriction or reducer coupling should be installed in discharge line.
NOTICE: The diagram below illustrates a pressure only relief valve. If local codes require a combination temperature
and pressure relief valve be installed, an extension piece may be needed.
Relief Valve
NOTICE: Local codes govern the installation of relief
valves. If local codes require that a temperature
and pressure relief valve should be installed the
manufacturer recommends a type 40XL Watts T&P
relief valve or an equivalent model be used.
NOTICE: Manual operation of relief valves should be
performed at least once a year. Turn off the electrical
power and gas shutoff valve. Lift and release lever
on the relief valve and check the manual operation of
the relief valve. You should take precaution to avoid
contact with the hot water coming out of the relief
valve and to prevent water damage.
NOTICE: If the relief valve on the system discharges
periodically, this may be due to thermal expansion
in a closed water supply system. Contact the water
supplier or local plumbing inspector on how to
correct this situation. Do not plug the relief valve.
