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. Use of this layout
should provide a trouble-free installation for the life of the
water heater. Before making the plumbing connections, locate
the COLD water inlet and the HOT water outlet. These fittings
are both 1 ½” NPT male thread. Install a shut-off valve close to
the water heater in the cold water line. 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 fittings are tight. It is imperative
that open flame is not applied to the inlet and outlet fittings,
as heat will damage or destroy the plastic lined fittings. This
will result in premature failure of the fittings, 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 qualified 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-Off 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.
A discharge line must be installed into the relief valve. The
discharge line:
• Must not be smaller than the outlet pipe size of the relief
valve.
• Must not terminate less than 6” (15.2 cm) and not more
than 12” (30.5 cm) above a floor drain.
• Must not be restricted in any way. Do not thread, cap, or
in any way restrict the end of this outlet.
• Must be of a material capable of withstanding 210
o
F
(99
o
C) without distortion.
• Must be installed to allow complete drainage of the relief
valve and discharge line.
• Must terminate at an adequate free-flowing drain.
2. Pressure Build-Up in a Water System
When the water heater operates, the heated water expands
creating a pressure build-up. This is a natural function and is one
of the reasons for installing a temperature and pressure relief
valve. If the cold water supply line has a built-in water meter,
check valve, or pressure-reducing valve, a suitable expansion
tank must be installed to prevent pressure build-up or water
hammer effect. Otherwise, the warranty is void. See Figure
13. An indication of pressure build-up is frequent relief valve
discharge. If the relief valve discharges water on a continuous
basis, it may indicate a malfunction of the relief valve and a
qualified service technician must be called to have the system
checked and the problem corrected.
