Heat traps installed in the inlet and outlet con-
nec ons help save energy.
NOTICE: Most water heater models
contain energy saving heat traps in the
inlet and outlet connec ons to avoid
the circula on of hot water within the
pipes. Do not remove the heat traps.
Connect the hot water supply

using 3/4 inch NPT to the
fi ng marked "H" (HOT).
Follow the same connec on guidelines
as for the cold water supply.
Install insula on (or heat

tape) on the water pipes
especially if the indoor
installa on area is subject to freezing
temperatures. Insula ng the hot water
pipes can increase energy effi ciency.
Double check to make sure

the hot and cold water pipes
are connected to the correct
hot and cold water fi ngs on the
water heater.
If needed, install (or adjust)

the home's Pressure Reducing
Valve to 50-60 psi and install a
Thermal Expansion Tank.
A Pressure Reducing Valve is required if your
home's water pressure is above 80 psi.
The Thermal Expansion Tank should be pres-
surized with air, to match the home's incoming
water pressure.
Step 8:
Verify connec ons and
completely fi ll tank
To remove air from the tank and allow
the tank to fi ll completely with water,
follow these steps:
Remove the aerator at the

nearest hot water faucet. This
allows any debris in the tank
or plumbing system to be washed out.
