The model GL8Ti can be piped horizontally from the side or vertically from the top. If you wish to install the unit horizontally, with the piping connections on the right side, you will have to be certain the tap between the two water tappings is plugged, the supplied Temperature and Pressure Relief Valve will need to be installed on top. See location of T&P relief valve in Fig. 2/2. If you wish to install the unit vertically, with the piping connections on top, you will have to be certain the tap on the side is plugged, the supplied Temperature and Pressure Relief Valve will need to be installed on top. See location of T&P relief valve in Fig. 2/3. FIG. 3/1 V C FW FIG. 3/2 G H E A Z F X Y T MODEL GL 2.5Ti - GL 4Ti The GL 2.5Ti and GL 4Ti water heaters can be installed under the sink. Wall mounting Fasten the supplied mounting bracket to the wall. Use screws that are suitable for the wall material and the weight of the heater. Hang the water heater on the bracket. Tug down wards on the heater to ensure that both “fingers” of the bracket are seated in the mounting slots. Floor Mounting Pipe connections CAUTION Closed system thermal expansion (for all models) Heater can sit on floor. Connect the cold water inlet pipe to the inlet nipple (marked with a blue ring) and the hot water outlet pipe to the outlet nipple (marked with a red ring). To reduce the risk of excessive pressures and temperatures in this water heater, install the supplied temperature and pressure protective equipment required by local codes but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems, ANSI Z21.22.The supplied temperature and pressure relief valve is marked with a maximum set pressure (150 psi) that does not exceed the marked maximum working pressure of the water heater. Install the valve in the opening provided and marked for this purpose in the water heater, and orient it or provide tubing so that any discharge from the valve will exit within 6 inches above, or at any distance below, the structural floor, and cannot contact any live electrical part.The discharge opening must not be blocked or reduced in size under any circumstances. National Plumbing codes require a drain pan for any water heater installation. Failure to install one is the sole responsibility of owner and/or installer. Reference UPC 2000 (Uniform Plumbing Code) Section 510- Protection from Damage or IPC 2000 (International Plumbing Code) Section 504- Safety Devices. Periodic discharge of the temperature and pressure relief valve or failure of the element gasket may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a check valve, backflow preventer or water pressure reducing valve which will create a closed water system. During the heating cycle of the water heater, the water expands causing pressure inside the water heater to increase. The temperature and pressure relief valve may discharge hot water under these conditions which results in a loss of energy and a build-up of lime on the relief valve seat. To prevent this from happening, there are two recommendations: 1. 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 1.5 U.S. gallons for every 50 gallons of stored water. 2. Install a 125 PSI pressure relief valve in the cold water supply line. Make sure the discharge of this valve is directed to an open drain and protected from freezing. Contact the local water supplier or plumbing inspector for information on how to control this situation. Do not plug the temperature and pressure relief valve. Instructions for use Starting and testing Temperature Setting Before connecting the power, fill the tank and system with water and check for leaks. To be certain that all air is out of the water system, open the hot water faucets on your fixtures until constant water flows from them, otherwise damage to the element may occur. To start the heating cycle: A) first make sure tank is full. Otherwise the heating element may be damaged. B) the red light will come on and remain on until that temperature has been reached, at which point the light will go off, but will automatically come back on when the water temperature drops below the setting chosen. After installation check the water temperature. If adjustment is necessary, remove front cover to adjust thermostat (D Fig. 4 -clockwise to increase the temperature and counter clockwise to decrease it). To reach the thermostat: 1. Pry off the round cover plate (V Fig. 3/1) from its right hand edge (W Fig. 3/1) with a small flat-head screwdriver. 2. Remove the Phillips screw revealed beneath the round cover plate. 3....
