Part 2 - Prepare the Water Heater
COLD WEATHER HANDLING
- If the water heater has been stored
in a very cold location (BELOW 0
o
F) before installation, handle with
care until the components come to room temperature. Failure to do
so could result in damage to the water heater.
Remove all sides of the shipping crate to allow the heater to be moved
into its installation location.
A. What’s in the Box
Components included with the water heater:
• Drain Valve
• Temperature and Pressure Relief Valve
• Use and Care Manual and Warranty
NOTE:
Some components may ship factory installed.
B. Locating the Water Heater
All water heaters eventually leak. Locate the water heater where any
leakage from the relief valve, related piping, tank, or connections
will not result in damage to surrounding areas or lower floors of the
building. Any water heater should be installed in such a manner that
if it should leak the resulting flow of water will not cause damage
to the area in which it is installed. National Plumbing codes require
a drain pan for any water heater installation. This drain pan should
be sized with a maximum depth of 2”, and a minimum diameter
2” greater than the diameter of the water heater. The drain pan
should empty into an open drain line. This drain line should be
3/4” ID minimum, piped to an open drain. Leakage damages ARE
NOT covered by warranty. Failure to install a drain pan is the sole
responsibility of the owner and/or installer. Reference UPC 2000
(Uniform Plumbing Code) Section 510 - Protection from Damage or
IPC 200 (International Plumbing code) Section 504 - Safety Devices.
Leakage damages ARE NOT covered by warranty.
In addition, water leak detection devices and automatic water shutoff
valves are readily available at plumbing supply houses. IT IS HIGHLY
RECOMMENDED BY THE MANUFACTURER TO INSTALL WATER LEAK
DETECTION DEVICES AND AUTOMATIC SHUTOFF VALVES IN ANY
WATER HEATER INSTALLATION WHERE A LEAKAGE OF WATER COULD
RESULT IN PROPERTY DAMAGES.
This water heater is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by warranty.
Failure to install the water heater indoors could result in property
damage, severe personal injury, or death.
2. Choose a location for the water heater as centralized to the piping
and electrical system as possible. Also, locate the water heater and
domestic water piping where it will not be exposed to freezing
temperatures. All piping should be insulated. Additionally, place the
water heater so that the drain, controls, and inlets/outlets are easily
accessible.
NOTE:
To save on heating costs and improve energy efficiency keep
the distance between the water heater and fixtures to a minimum
to reduce heat loss from excess piping and keep friction loss at a
minimum. Ensure all water heater piping is properly insulated to
minimize heat loss.
NOTE:
If you do not provide the minimum clearances shown in
Figure 1, it might not be possible to service the water heater without
removing it from the space.
NOTE:
A combustible door or removable panel is acceptable front
clearance.
NOTE:
In the State of California, the water heater must be braced,
anchored, or strapped to avoid moving during an earthquake.
Contact local utilities for code requirements in your area. Visit
http://www.dsa.dgs.ca.gov or call 1-916-445-8100 and request
instructions.
However, applicable local codes shall govern installation. For
residential water heaters of a capacity of greater than 52 gallons,
consult the local building jurisdiction for acceptable bracing
procedures.
3. Check area around water heater. Remove any combustible
materials, gasoline, and other flammable liquids.
1. Installation Area (Mechanical Room) Operating Conditions
• Ensure ambient temperatures are higher than 32
o
F / 0
o
C and
lower than 104
o
F / 40
o
C
• Avoid continuously high levels of humidity
• Never close existing ventilation openings
NOTE:
When installing in a zero clearance location, it may not be
possible to read or view some product labeling. It is recommended
to make note of the water heater model and serial number.
The service life of the water heater’s exposed metallic surfaces, such
as the junction box, is directly influenced by proximity to damp
and salty marine environments. In such areas higher concentration
levels of chlorides from sea spray coupled with relative humidity
can lead to degradation of water heater components.
Incorrect operating conditions can lead to damage to the heating
system and put safe operation at risk. Ensure that the installation
location adheres to the information included in this manual.
Failure to do so could result in property damage, serious personal
injury, or death. Failure of the water heater or components due
to incorrect operating conditions IS NOT covered by product
warranty.
This water heater must be installed upright in the vertical position
as described in this manual. DO NOT attempt to install this water
heater in any other orientation. Doing so will result in improper
water heater operation and property damage, and could result in
serious personal injury or death.
Households with small children, disabled, or elderly persons may
require a 120
o
F or lower temperature setting to prevent severe
personal injury or death due to scalding.
