PART 4 – HEATER PIPING
Failure to follow the instructions in this section WILL VOID the warranty and may result in property damage, serious 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 product warranty.
Do not apply heat to the Hot or Cold water heater connections. If sweat connections are used, sweat tubing to the adapter before fitting
adapter to the water connections on the heater. Any heat applied to the water heater connections will permanently damage the dip tube
and/or heat traps. Damages due to improper installation practices ARE NOT covered by warranty.
A. GENERAL PIPING INFORMATION
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. The
control module also provides low water protection by sensing the water level in the tank. Some codes/jurisdictions may require
additional external controls.
NOTICE
Installing the Optional High Output Cold Water Dip Tube – For longer hot water draw, remove the factory installed dip tube from the
cold water inlet and replace with the Optional High Output Cold Water Dip Tube. This can be done by hand.
Never use dielectric unions or galvanized steel fittings when connecting to a stainless steel storage tank or heater. Use only copper or
brass fittings. Teflon thread sealant must be used on all connections.
