Water heater installation

Water Line Connections

This manual provides detailed installation diagrams (see pages 34-48 of this manual) for typical methods of application for the water heater(s).

The water heater may be installed by itself, or with a separate storage tank, on both single and two-temperature systems. When used with a separate storage tank, the circulation may be either by gravity or by means of a circulating pump. When a circulating pump is used it is important to note that the flow rate should be slow so that there will be a minimum of turbulence inside the heater.

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 34-48 of this manual for suggested piping arrangements.

Thermometers (not Supplied)

Thermometers should be obtained and field installed as shown in 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 34.

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. When a circulating pump is used, it is important to note that the flow rate should be slow so that there will be a minimum of turbulence inside the water heater storage tank.

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 34.

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.

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 12-13 for information on replacement and other requirements.

CAUTION

Water Damage Hazard

•Temperature-Pressure Relief Valve discharge pipe must terminate at adequate drain.

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.
