Page 5: Quick Connect Multi System Installation
Quick Connect Multi System Installation • The Quick Connect Multi System allows the installation of two units together utilizing only the Quick Connect Cord. The Quick Connect Cord is 6 ft.(2m) long. Install the units 2-18" (50 - 457mm) apart from each other to ensure the cord will be able to reach between the units. (See Typical Plumbing diagram). (If the distance between the two units is too great, not only will the cord not be able to reach, but the water temperature may also become unstable because of the difference in pipe length between the two units). -
Page 6: Before Installation
Before Installation DANGER Checkup • Check the fixing brackets and vent pipe yearly for damage or wear. Replace if necessary. WARNING Precautions on Vent Pipe Replacement • The vent system will almost certainly need to be replaced when this appliance is being installed. Only use vent materials that are specified in this Installation Manual for use on this appliance. Refer to the "Vent Pipe Installation" section for details. If PVC, CPVC, or Category IV listed pipe is already installed, check for punctures, cracks, or blockages and consult with the vent pipe manufacturer before reusing. Improper venting may result in fires, property damage or exposure to Carbon Monoxide. Snow Precaution • If this product will be installed in an area where snow is known to accumulate, protect the vent termination from blockage by snow drifts or damage from snow falling off of roofs. Check the Gas • Check that the rating plate indicates the correct type of gas. EN19WI30LS1 • Check that the gas supply line is sized for 199,900 BTU 16,000 BTU 10.5" 199,900 Btuh. 2.8" Check the Power ANSI Z21.10.3-2011/CSA 4.3-2011 • The power supply required is 120VAC, at 60Hz. -
Page 7: Choosing Installation Site
Choosing Installation Site * Locate the appliance in an area where leakage from the unit or connections will not result in damage to the area adjacent to the appliance or to the lower floors of the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. The pan must not restrict combustion air flow. DANGER • Locate the vent terminal so that there are no obstacles around the termination and so that exhaust can't accumulate. - Page 8 • Before installing, make sure that the exhaust flue termination will have the proper clearances according to the National Fuel Gas Code (ANSI Z223.1). Prohibited State of California: The water heater must be braced, anchored or strapped to avoid moving during an earthquake. Contact local utilities for code requirements in your area or call: Electrolux Home Products, Inc. at 1-888-360-8557 and request instructions. The Commonwealth of Massachusetts: The water heater can be used for hot water only and not in a combination of domestic and space heating. For Venting Manufacturers Requirements, call Electrolux Home Products, Inc. at 1-888-360-8557 or visit us at www. electroluxappliances. com.

A malfunction may occur if two or more remote controllers are connected. * The water heater has been factory set to allow a maximum temperature setting of [120 °F / 50 °C]. To access higher temperature settings through the remote controller, follow the below steps. <When setting the maximum temperature to [125 -140 °F / 55 - 60 °C]> 1. Turn the water heater off by pressing the Power On/Off Button on the remote controller. 2. Press and hold the FLOW METER ALARM SET Button until a sound is heard (2 sec.) and [120 °F / 50 °C] appears on the display. 3. Set the upper limit of the hot-water supply temperature to [125 °F, 130 °F, 135 °F or 140 °F / 55 °C or 60 °C] using the UP and DOWN setting Buttons. 4. To put the water heater back into operation, press the Power On/Off Button on the remote controller. To keep the water heater off, let the unit sit for 30 sec. to return to the original display. • This unit can be programmed so that it will default to one of three temperatures if the remote controller is removed [140 °F (60 °C), 135 °F (57 °C), 120 °F (50 °C)]. To change the default temperature, adjust the dip switches as described below. The default temperature is 120 °F (50 °C). - Page 32 Connecting Remote Controller Cord to Unit • Keep the remote controller cord away from the freeze prevention heaters in the unit. • Tie the redundant cord outside the water heater. Do not put the extra length inside the equipment. • The remote controller cord can be extended up to 300' (90m) with 18AWG wire. • Use a Y type terminal with a resin sleeve. (Without the sleeve, the copper wire may corrode and cause problems). • Be sure to hand tighten when screwing to the terminal block. Power tools may cause damage to the terminal block. Remote controller cord • For extensions, a 26' (8m) cord can be purchased (Part #RC-CORD26) or use 18AWG wire. • Install according to the National Electrical Code and all applicable local codes. 1. Check to make sure that the remote controller cord has plenty of slack in order to reach the external connection terminal block. 2. Disconnect electrical power to the water heater. 3. Remove the single screw securing the terminal block cover and then remove the cover.

Page 35: Maintenance
Maintenance Periodically check the following to ensure proper operation of the water heater. • The venting system must be examined periodically by a qualified service technician to check for any leaks or corrosion. • The burner flame must be checked periodically for a proper blue color and consistency. • If the flame does not appear normal, the burner may need to be cleaned. • If the burner needs to be cleaned, it must be performed by a qualified service technician. • Do not obstruct the flow of combustion and ventilation air. • The pressure relief valve must be operated once a year to ensure that it is functioning properly and there is no obstruction. Turn the power off to the unit before opening the relief valve, and make sure that water draining out of the valve will not cause any damage. • If the relief valve discharges periodically, it may be due to thermal expansion in a closed water system. Contact the water supplier or a local plumbing inspector on how to correct this situation. Do not plug the relief valve. • See Use and Care Manual for further maintenance. Warning: There is a scald potential if the output temperature is set too high. Should overheating occur, or the gas supply fail to shut off, turn off the manual gas control valve to the appliance. Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water. -
Page 36: Lighting Instructions
CAUTION Handling after trial operation • If the unit will not be used immediately, close off all gas and water shutoff valves, drain all of the water out of the unit and the plumbing system to prevent the unit and system from freezing, and bleed the gas out of the gas line. Freezing is not covered by the warranty. WARNING A fire or explosion may result if these instructions are not followed, which may cause loss of life, personal injury or property damage. Lighting Instructions This water heater does not have a pilot. It is equipped with an ignition device that automatically lights the burner. Do not try to light the burner by hand. 1. Read the safety information in the installation manual or on the front of the water heater. 2. Turn off all electrical power to the unit. 3. Do not attempt to light the burner by hand. 4. Turn the gas control manual valve (external to the unit) clockwise to the off position. 5. Wait five minutes to clear out any gas.
