If one is not already installed,
install a manual shuto valve
in the cold water line that
supplies the water heater. Install the
shuto valve near the water heater so
that it is readily accessible. Only use
valves that are compable with
potable water. Use only full-ow ball
or gate valves. Other types of valves
may cause excessive restricon to the
water ow.
2
Install a Thermostac Mixing
Valve. Consult the valve
manufacturers instrucons
or a qualied person.

For water heaters that are fed
by a solar water heang
system (or any other pre-
heang system), always install a
Thermostac Mixing Valve or other
temperature liming device in the inlet
water supply line to limit water supply
inlet temperature to 120°F (49°C).
Solar water heang systems can supply
water with temperatures exceeding
170°F (77°C) and may result in water
heater malfuncon.

Determine the type of water pipes in
the plumbing system. Most systems
use copper water pipes, but some
use CPVC or cross-linked polyethylene
(PEX). Use ngs appropriate for the
type of pipe in the plumbing system.
Do not use iron or PVC pipe – they are
not suitable for potable water.
2
Connect the cold water
supply using 3/4 inch (19mm)
Naonal Pipe Thread “NPT
to the cold water inlet nipple.
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
local plumbing supplier). Dielectric
unions can help prevent corrosion
caused by ny electric currents
common in copper water pipes and
can help extend the life of the water
heater.

If the plumbing system has copper
water pipes, you can solder the
water pipe connecons or use
compression ngs which don’t
require soldering. Compression
ngs are easier to install than
soldering pipe. Check with local
plumbing ocials to determine
what types of pipe materials are
suitable for your locaon. Do not
use lead-based solder.
 Do not solder pipes while
they are aached to the water
heater. The water heaters inlet
and outlet connecons contain
non-metallic parts which could
be damaged. The proper way
to connect the water heater to
copper water pipes is as follows:
Solder a short length of pipe
(about a foot or so) to a
threaded adapter using only
95/5 n-anmony or equivalent
solder. Aach the threaded
adapters to the water heaters
connecons (using thread
sealant tape or pipe joint
compound). Connect the water
pipes by soldering, keeping the
connecons at the water heater
cool with wet rags.
