NOTE: Vent pipe is not included with the water heater.
When the installation is complete, visually inspect the venting
system to make sure that all joints are properly connected and all
instructions have been followed. Failure to properly install the
venting system can result in property damage, personal injury, or
death.
E. Water Piping
Refer to Figure 13 for a typical installation. Before making the
plumbing connections, locate the COLD water inlet and the HOT water
outlet. These ttings are both 1 ½” NPT male thread. Install shut-o
valves close to the water heater in both the hot and cold water lines.
It is recommended that unions be installed in the cold and hot water
lines so that the water heater can be easily disconnected if service is
required.
NOTE: It is recommended to use dielectric unions when connecting to
the water heater.
When assembling the hot and cold piping, use food grade pipe joint
compound and ensure all ttings are tight. It is imperative that open
ame is not applied to the inlet and outlet ttings, as heat will damage
or destroy the plastic lined ttings. This will result in premature failure
of the ttings, which is not covered by warranty.
1. Temperature and Pressure Relief Valve
DO NOT plug the temperature and pressure relief valve or its
discharge line. DO NOT remove the relief valve. Make sure the
relief valve is properly sized for the water heater. If the relief valve
continuously discharges water, call a qualied service technician
to correct the problem. Failure to follow these instructions can
result in property damage, personal injury, or death.
To protect from excessive pressure and/or temperature, the
manufacturer has installed a temperature and pressure relief valve
that meets the requirements of the Standard for Relief Valves and
Automatic Gas Shut-O Devices for Hot Water Supply Systems, ANSI
Z21.22 in the United States, and CSA 4.4 in Canada. This relief valve
has a maximum set pressure that does not exceed the hydrostatic
working pressure of the water heater (150 psi = 1,035 kPa) and a
BTU/H rating equal to or greater than the input rating, as shown on
the water heater rating plate. It should never be plugged or removed
from the opening marked for it on the water heater.
If this relief valve should need to be replaced, use only a new
temperature and pressure relief valve. Never install an old or existing
relief valve, as it may be damaged or inadequate for the working
requirements of the new water heater. This new relief valve must
meet all local codes, or, at minimum, the requirements listed above.
Never install any other type of valve between the relief valve and
the water heater.
To avoid water damage or scalding due to relief valve operation:
• Discharge line must be connected to relief valve outlet and
run to a safe place of disposal. Terminate the discharge line
in a manner that will prevent possibility of severe burns or
property damage should the relief valve discharge.
• Discharge line must be as short as possible and the same
size as the valve discharge connection throughout its entire
length.
• Discharge line must pitch downward from the valve and
terminate at least 6” above the oor drain, making discharge
clearly visible.
• The discharge line shall terminate plain, not threaded, with
a material serviceable for temperatures of 375
o
F or greater.
• Do not pipe discharge to any location where freezing could
occur.
• No valve may be installed between the relief valve and
heater or in the discharge line. Do not plug or place any
obstruction in the discharge line.
• Test the operation of the relief valve after lling and
pressurizing the system by lifting the lever. Make sure the
valve discharges freely. If the valve fails to operate correctly,
immediately replace with a new properly rated relief valve.
• Test T&P valve at least once annually to ensure the waterway
is clear. If valve does not operate, turn the heater “o” and
call a plumber immediately.
• Take care whenever operating relief valve to avoid scalding
injury or property damage.
FAILURE TO COMPLY WITH THE ABOVE GUIDELINES COULD
RESULT IN FAILURE OF RELIEF VALVE OPERATION, RESULTING
IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE
PERSONAL INJURY, OR DEATH.
Do not thread a cap or plug into the relief valve or relief valve
line under any circumstances! Explosion and property damage,
serious injury, or death may result.
