NOTES:
1. Minimum pipe size should match connection
size. Upsize pipe accordingly if greater fl ow is
required.
2. Drains and check valve between will assist in
purging air from system.
3. These drawings are meant to demonstrate
system piping only. The installer is responsible
for all equipment and detailing required by
local codes. In Massachusetts, you must install a
vacuum relief valve per 248 CMR.
4. A temperature and pressure (T&P) relief valve
is not required for most installations, but may be
required to meet local, state, or provincial codes.
If codes require a T&P valve, install according to
code and manufacturer instructions.
5. Mixing valve application is optional, but
recommended to help prevent scalding.
6. 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.
B. Plumbing
It is mandatory that all plumbing be done
in accordance with federal, local, and state
Failure of the water heater due to lime scale build-up on the heating surface, low pH, or other imbalance IS NOT
covered by the warranty.
Do not apply heat to the Hot or Cold water heater connections. If sweat connections are used, sweat tubing to
the adapter before fi tting adapter to the water connections on the heater. Any heat applied to the water heater
connections will permanently damage the water heater. Damages due to improper installation practices ARE
NOT covered by warranty.
C. Pressure Relief Device (PRD)
For protection against excessive pressures in this water heater, install the supplied pressure relief device (PRD).
The supplied PRD is marked with a maximum set pressure (123 psi). Install the PRD on the cold inlet line adapter
of the water heater, and orient it or provide tubing so that any discharge from the valve will exit at least 6” above
the structural fl oor. The relief line cannot be in contact with any live electrical parts. The discharge opening must
not be blocked or reduced in size under any circumstances.
National Plumbing codes require a drain pan for any water heater installation. Failure to install one is the sole
responsibility of 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.
Figure 8 - Installation Detail
plumbing codes and practices. Failure to properly install the water heater WILL VOID the warranty. It is also
necessary to use both thread tape and pipe dope on all mechanical plumbing connections.
Install unions on the hot and cold water connections to easily disconnect the water heater for servicing.
•
Connect the water inlet line to the entry point of the heater (left side inlet), and connect the outlet line to
the water outlet. Use a line that can withstand a minimum pressure of 58 psi. Using any other type of line
will cause damage. See Figure 8.
•
Residential plumbing systems with unstable pressure or pressure above 73 psi require the application of a
pressure stabilizer valve, set to 58 - 73 psi.
•
Do not install the appliance with water inlets and outlets at the top. See Figure 7.
D. Scalding
This water heater can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain
appliances such as dishwashers and automatic clothes washers may require increased water temperatures. By
setting the thermostat on this heater to obtain the increased water temperature required by these appliances
you may create the potential for scald injury.
