A. Locating the Water Heater
High heat sources (generating heat 100
o
F / 37
o
C or greater, such as
stove pipes, space heaters, etc.) may damage plastic components
of the water heater as well as plastic vent pipe materials. Such
damages ARE NOT covered by warranty. It is recommended to keep
a minimum clearance of 8” from high heat sources. Observe heat
source manufacturer instructions, as well as local, state, provincial,
and national codes, laws, regulations, and ordinances when installing
this water heater and related components near high heat sources.
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 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.
This water heater is certified for indoor use only. DO NOT INSTALL
OUTDOORS. Outdoor installations ARE NOT covered by warranty.
Choose a location for the water heater as centralized to the piping
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 boiler and water heater to a minimum
to reduce heat loss from excess piping and keep friction loss at a
minimum. Ensure all piping between the boiler and water heater is
properly insulated to minimize heat loss.
The water heater may be located some distance from the boiler
provided the circulator meets flow requirements through the coil.
The greater the distance from the water heater to the boiler the
longer the response will be to a call for hot water.
This water heater must be installed vertical on a level surface.
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 greater than 52 gallons, consult
the local building jurisdiction for acceptable bracing procedures.
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.

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.
NOTE: If you do not provide the minimum clearances shown in

NOTE: A combustible door or removable panel is acceptable front
clearance.
