water heater installation

t&p ValVe disCharge pipe

Explosion Hazard

Temperature-Pressure Relief Valve

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 water heater is provided with a properly rated/sized and

certified combination temperature - pressure (T&P) relief valve

by the manufacturer. See Temperature-Pressure relief Valve

on pages 13-14 for information on replacement and other

requirements.

Water Damage Hazard

Temperature-Pressure Relief Valve discharge

pipe must terminate at adequate drain.

•

CAUTION

Install a discharge pipe between the T&P valve discharge opening

and a suitable floor drain. Do not connect discharge piping

directly to the drain unless a 6” (15.2 cm) air gap is provided.

To prevent bodily injury, hazard to life, or property damage, the

relief valve must be allowed to discharge water in adequate

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.

t&p Valve discharge pipe requirements:

• Shall not be smaller in size than the outlet pipe size of the

valve, or have any reducing couplings or other restrictions.

•  Shall not be plugged or blocked.
•  Shall not be exposed to freezing temperatures.
•  Shall be of material listed for hot water distribution.
•  Shall be installed so as to allow complete drainage of both

the Temperature-Pressure relief Valve and the discharge

pipe.

• Must terminate a maximum of six inches above a floor

drain or external to the building. In cold climates, it is

recommended that the discharge pipe be terminated at an

adequate drain inside the building.

• Shall not have any valve or other obstruction between the

relief valve and the drain.

water line ConneCtions

The water piping installation must conform to these instructions

and to all local code authority having jurisdiction. Good practice

requires that all heavy piping be supported.
read and observe all requirements in the following sections

before installation of the water piping begins:
1.  Water Temperature Control and Mixing Valves on page 12.
2.  Dishwashing Machines on page 13.
3.  Closed Systems and Thermal expansion on page 13.
4.  Temperature-Pressure relief Valve on page 13-14.
5.  For  multiple  water  heater  installations  see  Water  Piping

Diagrams beginning on page 35.

water (potaBle) heating and spaCe heating

1. All piping components connected to this unit for space heating

applications shall be suitable for use with potable water.

2. Toxic chemicals, such as those used for boiler treatment,

shall NeVer be introduced into this system.

3. This unit may NeVer be connected to any existing heating

system or component(s) previously used with a non-potable

water heating appliance.

4. When the system requires water for space heating at

temperatures higher than required for domestic water

purposes, a tempering valve must be installed. Please refer

to installation diagrams on pages 35-49 of this manual for

suggested piping arrangements.

5. These water heaters cannot be used in space heating

applications only.

thermometers (not supplied)

Thermometers should be obtained and field installed as shown

the installation diagrams.
Thermometers are installed in the system as a means of detecting

the temperature of the outlet water supply.

water piping diagrams

This manual provides detailed water piping diagrams for typical

methods of application for the water heaters, see Water Piping

Diagrams beginning on page 35. The water heater may be

installed by itself, or with a separate storage tank. When used

with a separate storage tank, the circulation may be either by

gravity or by means of circulating pump. Adjust flow by throttling

a full port ball valve installed in the circulating line on the outlet

side of the pump. Never throttle flow on the suction side of a

pump. See the Water Piping Diagrams beginning on page 35.

note:

In addition to the factory installed Temperature-Pressure

relief Valve (T&P valve) on the water heater, each remote

storage tank that may be installed and piped to a water heating

appliance must also have its own properly sized, rated and

approved Temperature-Pressure relief Valve installed.
Call the toll free technical support phone number listed on the

back cover of this manual for further assistance in sizing a T&P

valve for remote storage tanks.
