Location
This water heater should be located as close as possible to a power
supply and to the main use of hot water. This location must not
be subject to freezing temperatures. The water heater should be
positioned so that the element and thermostat access doors can be
removed for inspection, adjustment, and servicing of the elements
and thermostats. The drain valve must also be accessible. The water
heater must be located close to a suitable free-flowing floor drain.
Where a floor drain is not adjacent to the water heater, a suitable
drain pan must be installed under the water heater (see Figure 1A
or 1B). This drain pan should be at least four (4) inches (10.2 cm)
larger than the diameter of the water heater, and at least one (1) inch
(2.5 cm) deep providing access to the drain valve. This pan must be
piped to a suitable drain to prevent damage to property in the event
of a water leak from the piping, the relief valve, or the water heater.
Sooner or later, all water heaters leak. The manufacturer,
based on national building codes has given the neces-
sary advice to prevent damage to the building. Under no
circumstances is the manufacturer to be held liable for
any water damage in connection with this water heater.
Should this water heater be installed on carpeting, the carpeting must
be protected by a wood or metal panel beneath the water heater. This
panel must extend at least three (3) inches (7.6 cm) beyond the width
and depth of the water heater. Should the water heater be installed in
an alcove or closet, the entire floor area must be covered by the panel.
Water Piping
Refer to Figure 1A or 1B 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 3/4” N.P.T. male
thread. Make sure that the dip-tube is installed in the cold water inlet
(Top entry Models). 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 discon-
nected, if servicing is required.
When assembling the hot and cold piping, use Teflon™ food grade of
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 dam-
age or destroy the plastic lined fittings. This will result in premature
failure of the fittings, which is not covered by the warranty.
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, 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, CSA 4.4, in Canada, and ANSI Z21.22, in the United
States MUST BE installed by the installer when it has not been factory
installed. The relief valve should have a maximum set pressure that does
not exceed the hydrostatic working pressure of the water heater (150 psi
= 1,034 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 tem-
perature and pressure-relief valve. Never install an old or existing relief
valve, as it may be damaged or inadequate for the working require-
ments of the new water heater. This new relief valve must meet all local
codes or, at a minimum, the requirements listed above. Never install
another 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 six (6) inches (15.2 cm) and not more
than twelve (12) inches (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˚F (99˚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.
Pressure Build-up in a Water System
When the water heater operates, the heated water expands creat-
ing 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 1A or 1B). An indication of pressure
build-up is frequent discharges of water from the relief valve. 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.
Filling the Water Heater
NEVER operate the water heater unless it is completely
filled with water. Failure to follow this instruction can result in
premature failure of the water heater and its component parts
that is not covered by the warranty.
Check that all of the water piping connections have been made. To
fill the water heater:
1) Make sure that the water heater drain valve is closed by inserting
a flat head screwdriver into the slot on the head of the drain valve
and turning the knob clockwise .
2) Open the cold water supply manual shut-off valve. This valve
must remain open, as long as the water heater is in use. NEVER
operate the water heater with the cold water supply manual
shut-off valve closed.
3) To make sure the water heater is completely filled with water, open
all of the hot water faucets in the house to let the air out of the
water heater and plumbing system. Leave the faucets open until a
constant flow of water is obtained.
4) Check all of the plumbing connections to make sure there are no
leaks.
