READ AND FOLLOW ALL INSTRUCTIONS. - This heater is designed only for the heating of water and should not be used for other applications or used to heat any other media. When using this equipment, basic precautions should always be followed. Safety Definitions This symbol is the safety alert symbol which is used to alert you to potential hazards that can kill or hurt you and/or others. Indicates an imminently hazardous situation which if not avoided will result in death or serious injury.
- A 120 V / 60 Hz power source should be used. Fire, electrical shock or damage to the water heater may occur if an incorrect power supply is used. - This appliance is equipped with a three-prong grounded plug for increased protection against electrical shock. Ensure the plug is properly inserted into a clean, dry outlet that complies with all electrical codes. Only insert and remove the plug using the plug head and never use a wet hand to plug or unplug the power plug.
Control Panel “Water valve” - Indicates one of the following three states: The Control Panel and display are used to adjust the operational settings of the unit as well as give information about the current state of operation. The following illustration shows all possible symbols and signs that may appear in various states of operation. In operation only the symbol or sign corresponding to the actual state will appear on the control panel display.
6. When the desired temperature is set above 122ºF (50ºC), the temperature display blinks for approximately 4 seconds before the display switches to show actual water temperature. 3. Displayed volume: Please note that the readout indicates the water quantity divided by ten (10). Example – if the display shows “10”, this correlates to a volume of 10x10 = 100 gallons (English unit mode) or 100 liters (metric unit mode). 7.
OPTIONAL WIRED REMOTE CONTROL PANEL (GA16ETL) The heater may be controlled by a wired remote control (optional). The controller can be located near a bath, shower or other location. Figure - Wired Remote Control Panel to the system. At any given time, one of the control panels can become the “priority” controller. The priority controller becomes the master temperature control device for the system.
- After a power outage, all settings return to their factory default values. 7. Open the drain valve plugs and completely drain the water heater. 8. Continue draining to empty the whole hot water system. The heater and water within the unit may be very hot. Allow time for the system to cool and use caution when draining to minimize risk of injury. Note: Freezing temperatures below 32ºF (0ºC) can cause permanent damage to the heater and/or the piping system. 9.
Cold Weather with Potential Freezing Temperatures Routine Inspection Keep water flowing through the system to guard against freezing. Follow these steps: The heater and exhaust piping will be hot during and shortly after use. Use caution when working in the area around the heater. 1. Close the fuel gas valve. 2. Turn off the power by pressing the “ON/OFF” button. “CL” will be displayed when off. 3. Open the hot water faucet at one or more points of use (sink, upstairs bathtub, etc.
Examine venting system to insure system is clear of blockages, debris, and damage. - Four gallons of virgin food grade white vinegar or virgin food grade citric acid. - Small inline recirculation pump capable of circulating 2 - 4 gpm (8 – 16 l/m). Clean inside of unit by vacuuming or blowing out dust that collects in the unit. The burner and heat exchange are sealed units and should not be opened. - Set of hoses for connecting recirculation pump to and from the pump and the five gallon container.
7. Open valves V1 and V2 into the water heater. 8. Operate the pump. Circulate the cleaning solution through the water heater for at least 45 minutes. Trouble No “CL” displaying. Possible Cause Power outage. Unit requires 120V power. Use unit when power is restored. Check circuit breaker and reset if needed. Check ground fault circuit interrupter (GFCI) if circuit includes one and reset if necessary. Unit is unplugged. Check power plug and ensure properly plugged. Plug the power plug properly.
Trouble Hot water is not the right temperature (too hot or too cold). Possible Cause Temperature set point was reset due to power outage. Power outage restores default settings and custom set points must be re-entered to unit Temperature set point incorrect. A remote wired controller is controlling temperature set point. Release override control of this remote (see “Remote Control Panel Functions”) or change set point to desired temperature with that remote. Flow is beyond capacity.
Trouble The volume alarm does not sound even though the volume appears to be adequate. Possible Cause Units incorrect during input Measuring flow of only hot water instead of hot water and cold water combined Unresolved problem. Other assistance required. Remedy Refer to “Set a Desired Volume” section to ensure units (metric vs. English) and volume (displayed volume number represents 1/10th of the actual total flow) is correctly set. Code Indication E0 Blower system problem occurred.
Code E3 Indication Remedy 2.Ignition sequence was unsuccessful. 2. Check fuel gas supply (especially when first installed as air pockets might exist in the gas line. Retry the ignition process several times). sudden event such as excessively low pressure in water supply or excessively high gas supply pressure. 3.An accidental flameout occurred. 3. Check if the fuel gas pressure is too high or too low 2. The temperature controller or the high temperature fusible protection wire has separated. 4.
Only properly qualified personnel should install this equipment. Improper installation or installation by a non-qualified installer may void warranty. Failure to comply with state and local codes pertaining to water heater installations may void also warranty. The following contents are included. If any items are missing contact authorized after sales service.
- Ventilation requirements must be considered when choosing installation location. - Minimizing vent piping will reduce installation costs and maximize efficiency. We recommend that a service valve kit be used for the installation as it will reduce installation costs and make servicing the water heater easier. The Webstone 44043PR or similar service valve kit.
3. Measure and mark the center locations for three (3) holes according to the installation measurements below. Ensure compliance with applicable electrical codes during installation including the U.S. National Electric Code (NFPA 70) or the Canadian Electrical Code – Part 1 (CGAS C22.1) depending on location. 1. Ensure that a properly grounded 120 V/ 60 Hz three prong outlet is available. DO NOT PLUG IN THE UNIT UNTIL INSTALLATION IS COMPLETE, TESTED, AND READY FOR INITIAL START UP.
8. Attach the wires to the terminal connectors using Y shaped crimp connections or wrap the thermostat wires around the screws then fasten the screws to secure the terminal connectors. Inspect and insure that the Y connectors or the thermostat wires are not touching each other. 5. Reinstall the PCB controller and replace the front cover of unit. 9. Mount controller to wall by drilling 2) 6mm holes 92mm (4") apart at installation location, and insert the Expansion Anchors supplied.
Ensure any leak check solution is non-corrosive and is completely rinsed from the piping after leak check is complete. Corrosion of the gas piping and subsequent leaks could occur. Never use flammable solutions or an open flame to test for gas leaks! Install proper drainage for discharge of temperature and pressure relief valves per local code when relief occurs and do not reduce or restrict line. Discharge line shall be installed to allow complete drainage of both valve and line.
- Air intake pipe may be ABS, PVC, galvanized steel, corrugated aluminum or other materials acceptable to local codes. - The heater requires a direct vent. Exhaust vent must be of AL 29-4C® Stainless Steel vent directly to the outside of the building. - The exhaust vent will have been tested to meet Underwriters Laboratories, Inc. to UL 1738 and ULC-S636. - The system must use outside air for combustion. Ensure the incoming air is not contaminated by any potential source of fumes or chemicals.
