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 during standby. Do not remove
the heat traps.
3
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.
4
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.
5
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.
6
If needed, install (or adjust)
the home’s Pressure Reducing
Valve to 50-60 psi and install a
Thermal Expansion Tank.
Figure 15 - A Pressure Reducing Valve is required
if your home’s water pressure is above 80 psi.
Figure 16 - The Thermal Expansion Tank should
be pressurized 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:
1
Remove the aerator at the
nearest hot water faucet. This
allows any debris in the tank
or plumbing system to be washed out.
2
Turn the cold water supply
back on.

valve.
3
Open a hot water faucet and
allow the water to run un l it
fl ows with a full stream.
4
Let the water run full stream
for three full minutes.
5
Close the hot water faucet
and replace the aerator.
6
Check inlet and outlet
connec ons and water pipes
for leaks. Dry all pipes so that
any drips or leaks will be apparent.
Repair any leaks. Almost all leaks occur
at connec ons and are not a tank leak.
