•Must be installed to allow complete drainage of both the valve and discharge line.

•Must not discharge so as to come in contact with any electrical part or wiring.

Under no circumstances is the manufacturer to be held responsible for any water damage in connection with this water heater.

IMPORTANT:

This water heater must be installed strictly in accordance with the instructions enclosed, and local electrical, fuel and building codes. It is possible that connections to the water heater, or the water heater itself, may develop leaks. IT IS THEREFORE IMPERATIVE that the water heater be installed so that any leakage of the tank or relat- ed water piping is directed to an adequate drain in such a manner that it cannot damage the building, furniture, floor covering, adjacent areas, lower floors of the structure or other property subject to water damage. This is particular- ly important if the water heater is installed in a multi-story building, on finished flooring or carpeted surfaces. GSW WILL NOT ASSUME ANY LIABILITY for damage caused by water leaking from the water heater, pressure relief valve, or related fittings. Select a location as centralized within the piping system as possible. In any location selected, it is recommended that a suitable drain pan be installed under the water heater. This pan must limit the water level to a MAXIMUM depth of 45mm (1 3/4 in.) and have a diameter that is a minimum of 50mm (2 in.) greater than the diameter of the water heater. Suitable piping shall connect the drain pan to a properly operating floor drain.

WARNING!

Closets without drains and carpeted areas are examples of unsuitable locations for any water heater. Select a location as centralized within the piping system as possible. The heater should be located in an area not subject to freezing temperatures. If this heater is to be installed directly on car- peting, the carpeting must be protected by a metal or wood panel beneath the heater, extending beyond the full width and depth of the heater by a minimum 80mm (3 in.). If the heater is installed in a closet or alcove, the entire floor must be covered by the panel. This panel must be strong enough to support the weight of the heater full of water without breaking. Failure to heed this warning may result in a fire hazard.

Closed System/Thermal Expansion

During the heating cycle of the water heater, the water expands causing pressure inside the water heater to increase. The water utility supply meter may contain a check valve. This will create a closed water system. If the pressure in a closed water system exceeds 1034kPa (150 PSI), water will discharge from the temperature and pres- sure (T&P) relief valve. This is the normal safety function of a relief valve and indicates the proper functioning of the valve. Only if the discharge from the relief valve is continu- ous or for an extended period of time does this indicate a malfunction of some sort. Should this occur, have the oper- ation of the heater checked by a technician qualified to do so. Frequent operation of the T&P valve can result in a build up of natural mineral deposits on the valve seat, rendering the valve inoperative. Should this happen, the valve needs to be replaced. To prevent this from happening install a diaphragm-type expansion tank, that is suitable for potable water, on the cold water supply line. The expansion tank must have a minimum capacity of 6 litres (1.5 USG.) for every 190 litres (50 USG) of stored water and be rated for 1034kPa (150 PSI) or the working pressure of the water heater. NEVER PLUG OR REMOVE the T&P valve.

Important: Do not plug or remove the temperature and pressure relief valve.

WARNING

Excessive Weight Hazard

Use two or more people to move and install water heater.

Failure to do so can result in back or other injury.

Unpacking the Water Heater

Important: Do not remove any permanent instructions, labels, or the data label from the outside of the water heater or on the inside of panels. Remove exterior packaging and place installation components aside. Inspect all parts for damage prior to installation and start-up. Completely read and understand all instructions before attempting to assem- ble and install this product. After installation, dispose of packaging material in the proper manner.

Important: Strictly follow the installation instructions before making electrical connections.

Piping Installation

Piping, fittings, and valves should be installed according to the installation drawing (Figure 4). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation. Water supply pressure should not exceed 80% of the working pressure stated on the water heater’s data plate. If the supply pressure is high- er than this limit, a pressure limiting valve with a bypass must be installed in the cold water inlet line. This should be placed on the supply to the entire building in order to main- tain equal hot and cold water pressures.
