INSTALLATION
2
Connect the cold water supply
using 3/4 inch Na onal Pipe
Thread “NPT” to the fi ng marked “C”
(COLD).
For ease of removing the water heater
for service or replacement, connect
the water pipes with a coupling
called a union. We recommend using
a dielectric-type union ( available at
your local plumbing supplier). Dielec-
tric unions can help prevent corro-
sion caused by ny electric currents
common in copper water pipes and
can help extend the life of the water
heater
NOTICE: Most water heater models
contain energy saving heat traps in the
inlet and outlet connec ons. Do not
remove the heat traps.
3
Connect the hot water supply
using 3/4 inch NPT to the
fi ng marked “H” (HOT).
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 e
ffi ciency.
5
Adjust (or install) the home’s
Pressure Reducing Valve to
50-60 psi and install a Thermal
Expansion Tank.
Figure 28 - A Pressure Reducing Valve is required
if your home’s water pressure is above 80 psi.
Figure 29 - The Thermal Expansion Tank should
be pressurized with air, using a hand pump, to
match the home’s incoming water pressure.
Step 9:
Verify Connec ons and
Completely Fill 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 debris in plumbing
system to be washed out of the pipes.
2
Turn the cold water supply
back on and
fi ll the tank.
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 minutes.
5
Close the hot water faucet
and replace the aerator.
