Part 4 - Piping

Failure to follow the instructions in this section WILL VOID the 

warranty and may result in property damage, severe personal injury, 

or death.

DO NOT pipe this water heater with black iron, galvanized steel, steel, 

or lead pipe. Doing so will result in premature product failure and 

property damage, and WILL VOID the warranty. 
Do not apply a torch within 12” of the water heater. If sweat 

connections are used, sweat tubing to the adapter before fitting 

adapter to the water connections on the heater. Damages due to 

improper installation practices ARE NOT covered by warranty.
Dielectric unions or galvanized steel fittings must not be used in a 

system with this water heater. Doing so WILL VOID the warranty. Use 

only copper, brass, or stainless steel fittings. Teflon thread sealant 

must be used on all connections.

Plumbing of this appliance should only be done by a qualified, licensed 

plumber in accordance with all local plumbing codes. 

Use two wrenches when tightening water piping at heater. Use one 

wrench to prevent the heater return or supply line from turning. 

Failure to prevent piping connections from turning could cause 

damage to heater components.
The heater control module uses temperature sensors to provide both 

high limit protection and modulating temperature control. Some 

codes / jurisdictions may require additional external controls. 
Pump motors should not be supported by any type of stand due 

to possible misalignment of pump and motor. Failure to follow this 

instruction may result in property damage or personal injury.

A. General Plumbing Information

The domestic water connections must be installed in accordance to all 

local and national plumbing codes, or any applicable standard which 

prevails. The inlet (cold) and outlet (hot) ports are 3/4” on all models.

• 

Pipe material must be suitable to meet local codes and industry 

standards.

• 

The pipe must be cleaned and without blemish before any 

connections are made.

• 

All water piping should be insulated.

It is recommended to install a sweat shut-off valve and a union in the 

cold inlet piping and hot outlet to ease future servicing. If there is a 

backflow preventer or any type of a no return valve in the system, install 

an additional tee here, suitable for a potable hot water expansion tank.

In the hot outlet, install a suitable adapter to match the copper tubing 

of the plumbing system. A thermal trap or heat trap loop may be 

installed here to provide additional energy savings and prevent the 

thermal siphoning of domestic hot water.

B. Auxiliary Connections

The auxiliary connections are additional connections for a recirculation 

connection, air handlers, plate exchangers, or other devices that 

supply hot water. These connections must be installed in accordance 

with all local and national codes or any applicable standard that 

prevails. Auxiliary connections are 3/4” on all models. Never use 

dielectric unions or galvanized steel fittings. Use only copper or brass 

fittings. Sealant must be used on all connections.

Never connect auxiliary connections to any system that uses glycol 

or other solutions formulated for hydronic systems. These auxiliary 

connections are to be used only in a potable water system. Failure 

to follow this warning could result in serious injury or death.

D. Potable Expansion Tank

A potable hot water expansion tank is required to offset heated 

water expansion. In most city plumbing systems, the water meter 

has a no return or back flow device built into the system to prevent 

back flowing of water into city mains. Some local codes require 

back flow preventers on all incoming water supplies. The hot water 

expansion tank must be listed for potable water use. The expansion 

tank should be located on the cold inlet piping close to the water 

heater.

Expansion Tank and Make-Up Water

1. Ensure that the expansion tank is sized to correctly handle heater 

and system water volume and temperature.

Undersized expansion tanks cause system water to be lost from 

the relief valve, causing make-up water to be added. Eventual 

heater failure can result due to excessive make-up water addition. 

SUCH FAILURE IS NOT COVERED BY WARRANTY.

The expansion tank must be suitable for hot potable water 

systems.

2. The expansion tank must be located as shown in Applications, this 

manual, or following recognized design methods. See expansion 

tank manufacturer’s instructions for details.

Expansion tanks must be sized according to total system volume. 

This includes all length of pipe, all fixtures, heaters, etc. Failure to 

properly size for system expansion could result in wasted time, 

money, possible property damage, serious personal injury, or death.

WARNING

!

C. Backflow Preventer

Use a backflow preventer specifically designed for water heater 

installations. This valve should be installed on the cold water fill 

supply line per local codes.

E. Temperature and Pressure Relief Valve

Overheated water and high pressures can cause water tank 

explosion. A properly sized temperature and pressure relief valve 

must be installed in the opening provided on the water heater. 

Failure to install a properly sized temperature and pressure relief 

valve could result in explosion and property damage, serious 

injury, or death.
Do not thread a cap or plug into the relief valve or relief valve 

line under any circumstances! Explosion and property damage, 

serious injury, or death may result.
