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.

T & P Valve and Pipe Insulation

Remove insulation for T & P valve and pipe connections from

carton.

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/

CSA 4.4 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 Shut-off 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 = 1,035kPa) 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.
