Look at the top of the water heater. The cold water inlet is
marked “COLD". Put two or three turns of teflon tape around

the threaded end of the threaded-to-sweat coupling and
around both ends of the 3/4” NPT threaded nipple. Using
flexible connectors, connect the cold water pipe to the cold
water inlet of the water heater.

NOTE: This water heater is super insulated to minimize
heat ioss from the tank. Further reduction in heat loss

can be accomplished by insuiating the hot water lines
from the water heater.

PIPE

INSULATION FLUE PIPE

Fit pipe insulation over the incoming cold water line and the hot
water line. Make sure that the insulation is against the top
cover of the heater.

Fit T & P valve insulation over valve. Make sure thatthe insulation

does not interfere with the lever of the T & P valve.

Secure all insulation using tape.

Temperature-Pressure Relief Valve

A

warning

Explosion Hazard

Temperature-pressure relief vaive

must comply with ANSI Z21.22

and ASME code.

Properly

sized

temperature-

pressure relief valve must be

installed in opening provided.

Can result in overheating and
excessive tank pressure.

Can cause serious injury or death.

This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.

The valve is certified by a nationally recognized testing

laboratory that maintains periodic inspection of production of
listed equipment of materials as meeting the requirements for
Relief Valves and Automatic Gas Shutoff Devices for Hot Water
Supply Systems, ANSI Z21.22 and the code requirements of

ASME.

If replaced, the valve must meet the requirements of local codes,
but not less than a combination temperature and pressure
relief valve certified as indicated in the above paragraph.

The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water

heater (150 psi = 1,035 kPa) and a discharge capacity not less

than the water heater input rate as shown on the model rating

plate.

For safe operation of the water heater, the relief valve must not
be removed from its designated opening nor plugged.

The temperature-pressure relief valve must be installed directly

into the fitting of the water heater designed for the relief valve.
Position the valve downward and provide tubing so that any

discharge will exit only within 6 inches (153 mm) above, or at
any distance below the structural floor, see Figure 16. Be certain
that no contact is made with any live electrical part. The
discharge opening must not be blocked or reduced in size

under any circumstances. Excessive length, over 30 feet
(9.14 m), or use of more than four elbows can cause restriction

and reduce the discharge capacity of the valve.

No valve or other obstruction is to be placed between the relief

valve and the tank. Do not connect tubing directly to discharge
drain unless a 6 inch air gap is provided. To prevent bodily

injury, hazard to life, or property damage, the relief valve must
be

allowed

to

discharge

water

in

quantities

should

circumstances demand. If the discharge pipe is not connected
to a drain or other suitable means, the water flow may cause

property damage.
