NOTE: To protect against untimely corrosion of hot and coid
water fittings, it

is strongly

recommended that di-electric

unions or couplings be installed on this water heater when
connected to copper pipe.

FitT

&

P valve insulation over valve. Make sure that the insulation

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

Secure all insulation using tape.

1. Look at the top cover of the water heater. The hot water outlet

is marked hot. 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” threaded nipple. Using flexible

connectors, connect the hot water pipe to the hot water outlet

of the water heater.

2.

Look at the top cover 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” threaded nipple. Using flexible

connectors, connect the cold water pipe to the cold water

inlet of the water heater.

NOTE:

Your water

heater

is insulated

to minimize

heat ioss

from the tank. Further reduction in heat ioss can be
accompiished by insulating 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.

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.

Temperature-Pressure Relief Valve

A

warning

Explosion Hazard

Temperature-pressure relief valve

must comply with ANSI A21.22

andASMEcode.

Properly sized temperature-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 for Hot Water Supply Systems, ANSI Z21.22 • CSA

4.4, 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 electric heaters, watts x 3.412 equals Btu/hr input

rate)

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.
