Inspect all components. The contents of your box should include one of the following units:
This product is designed to be installed indoors only.
DO NOT install this product in a location where it may be subjected to freezing temperatures. If the water inside your tankless water heater freezes, it can cause severe and permanent damage that is not covered under your warranty.
DO NOT locate the water heater in a location that is difficult to access.
Make sure that the water heater and hot water outlet pipe are out of reach of children so they are unable to tamper with the temperature controls or injure themselves by touching the hot water outlet pipe. The outlet water pipe can get very hot.
This product does NOT require venting.
Avoid installing your tankless water heater in a location prone to excessive humidity, moisture, or dust, or in an area where it may be splashed with water or other liquids. DO NOT install under water pipes or air conditioning lines that might leak or condense moisture that could then drip onto the heater. DO NOT install above electrical boxes or junctions.
CAUTION The water heater should not be located in an area where leakage will result in damage to the area adjacent to it or to lower floors of the structure. Where such areas cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the water heater. Make sure to follow all code requirements for such installations as required for your area. We recommend that you install a drip pan (connected to a safe drain) below the water heater to avoid property damage in the unlikely event of a leak. Alternatively, you can install an active water leak detector and shutoff valve designed to turn off your water supply in the event that a leak is ever detected.
Your tankless water heater should be secured to the mounting surface with 4 screws (minimum 1” (25.4mm) long) using the built-in mounting brackets on each side of the heater (heaters 18-36kW) and follow the installation template for heaters 8-13kW. Make sure that the mounting surface is solid and secure, and ensure that the unit is level prior to securing the screws. For ease of installation and servicing, we recommend that this product be installed in an upright position with the inlet and outlet water connections at the bottom of the unit for the 18, 24, 27, and 36 kW heaters, and with the inlet and outlet water connections on the left and right sides of the unit for the 8, 11, and 13 kW heaters.
Recommended Clearances:
Flammable materials should be kept at least 24” (609.6mm) away from your water heater and the hot water outlet pipe.
Please follow all plumbing instructions carefully. We recommend that this product be installed by a licensed and qualified plumber in accordance with all applicable national, state, provincial, and local plumbing codes.
Installation Instructions
STEP 1: Thoroughly flush cold supply line of debris and connect the HOT WATER line to the water heater OUTLET located on the left side of the heater when facing unit. Connect the COLD WATER line to the water heater marked COLD WATER INLET on the right side when facing unit.
STEP 2: After tightening both fittings at the water heater, open several hot water faucets and allow water to run though the water heater for at least 2 to 3 minutes. This process purges all the air from the water lines and MUST be performed prior to turning on the power at the unit. FAILURE TO FOLLOW THIS STEP CAN CAUSE PERMANENT DAMAGE TO THE HEATING ELEMENTS. If any maintenance is performed on the water heater or the home’s plumbing system that may introduce air into the plumbing pipes, it is important to turn the power off to the water heater and purge the air out of the lines before allowing the unit to power up.
STEP 3: Carefully inspect all connections, unions, and the pressure relief valve (if installed) for leaks.
IMPORTANT NOTES:
We recommend that all the water pipes or hoses within 3’ (1m) of the inlet and outlet connections be rated for high temperature applications with a 150°F (66°C) minimum.
WARNING-CHECK FOR LEAKS BEFORE PROCEEDING TO ELECTRICAL INSTALLATION
WARNING Manufacturer recommends that this product be installed by a licensed and qualified electrician in accordance with all applicable national, state, provincial, and local electrical codes. As with all electrical appliances, under no circumstances should you attempt to install, repair or disassemble this water heater without first shutting off all power to the unit directly at the fuse or breaker box. Make sure to shut off all breakers. SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
All wiring (wire gauge) and circuit protection (breakers) must comply with the U.S. National Electrical Code (NEC) in the USA, or the Canadian Electrical Code (CEC) in Canada. Failure to do so could result in property damage and/or personal injury, and void your warranty. Note: The Canadian Electrical Code generally requires that all supply wires and corresponding circuit protection used for domestic hot water heating and hydronic heating applications be sized to a minimum of 125% of the maximum current rating of the heater (see heater specifications below for details).
Before installing this product, ensure that the home has sufficient electrical power available to handle the maximum amperage load of the applicable heater.
IMPORTANT NOTES:
Please see electrical specifications by heater input and wiring diagram on the next page for additional electrical information.
Each set of wires must be connected to its own individual double pole breaker.
Installation Instructions
STEP 1: Take each wire pair and connect them to one breaker (see wiring diagram). Make sure that each breaker is connected with one black wire and one red wire
STEP 2: Using a suitable wire gauge that meets all applicable electrical codes for the size of the breakers used, run the correct sets of wire from the home’s main breaker panel to the tankless water heater.
STEP 3: A separate ground conductor for each incoming circuit is required.
STEP 4: DOUBLE CHECK the electrical connections to make sure they are correct and that all wire connections are tight and secure. Also confirm that the correct breaker size and wire gauge has been used and confirm that the unit has been connected to a ground in accordance with applicable codes.
STEP 5: Confirm that all the air has been purged from the water lines prior to turning on power to the unit. Refer to STEP 2 in the plumbing installation section.
CAUTION: Ensure that you have made the correct connections. You must follow the wire connection as shown to ensure proper operation of the unit. If you mix up one set of wires with another, the unit will not operate correctly even though it turns on and otherwise appears to function properly.
The water heater is now installed and ready to use! Follow the General Operating Instructions to complete the setup. We highly recommend that this is done with the homeowner present.

FLOW REGULATOR – OPTIONAL
To ensure the optimal temperature output and overall performance of your tankless water heater you may require a flow regulator. These flow regulators are installed on the outlet connection of your tankless water heater and limit the maximum volume coming out of your unit to a specified flow rate to prevent the exit temperature from becoming too cool. To learn more about flow regulators or find out how to purchase one for your tankless water heater contact Manufacturer’s national service department at 1-(800)-374-8806.
Steps for Choosing a Flow Regulator
*Selection based on inlet temperature above and outlet temperature of 105°F (41°C)
Operating your new tankless water heater is similar to using any traditional water heating system. However, it is very important that you carefully read all of the setup procedures and operating instructions and tips to ensure the maximum performance and energy savings from your new water heater. We recommend that all members of the household read these General Operating Instructions.
How your new water heater works: Your tankless water heater does not store hot water like a conventional tank-type water heater. It contains heating elements that are capable of heating water on-demand. As soon as you turn on a hot water faucet, a sophisticated flow sensor recognizes that you have turned on the water. This sensor measures flow rate while another sensor measures the incoming water temperature. This information is transmitted continually to the computer logic controls which decide how much power to send to the heating elements to heat the water to your desired temperature. Once the water faucet is turned off your water heater will turn off as well.
Water Quality: Quality of water should be taken into consideration when installing and maintaining the water heater. Water conditions outside the recommended levels outlined below are not permitted and can damage the water heater. Manufacture reserves the right to deny any warranty claim regarding damage suffered due to use in water conditions not in accordance with the table below.
If water heater is installed in an area that is known to have hard water that cause scale build-up, the water must be treated and/or the heater exchanger flushed regularly to prevent damage to heat exchanger and/or heating elements.
A water treatment device or water softener should be installed to maintain optimal performance of the water heater in hard water areas. Contact customer service for additional information on these accessory kits.
IMPORTANT NOTES:
DANGER As with all electrical appliances, under no circumstances should you attempt to install, repair or disassemble this water heater without first shutting off all power to the unit directly at the fuse or circuit breaker. SERIOUS BODILY INJURY OR DEATH COULD OCCUR IF YOU IGNORE THIS WARNING.
When any maintenance is performed on the water heater or the home’s plumbing system that may introduce air into the plumbing pipes, it is important to turn the power off to the water heater and purge the air out of the lines before allowing the unit to power up. FAILURE TO DO SO COULD CAUSE PERMANENT DAMAGE TO THE HEATING ELEMENT AND VOID YOUR WARRANTY.
If you have a water supply with a high level of mineralization (hard water), you should increase the frequency of your maintenance.
