Installing a Noritz Water Heater
If you are a homeowner who does not mind getting their hands dirty, installing a Noritz tankless water heater, or any water heater, could be an interesting adventure. This installation process is nothing too complicated if you are prepared to study the manual through and through because this process requires some expertise and knowledge of plumbing and electrical connections. Below are the general steps involved in installing a Noritz tankless water heater.
Step 1: Review the installation manual
You must familiarise yourself with the installation guidelines, requirements, and safety precautions about the tankless water heater you are trying to install- this exercise will save you a lot of pain, especially those associated with determining where what goes. Moreso, ensure that it is a manual specifically made for the device you are trying to install to get a tailor-made guide.
Step 2: Choose a suitable location
Picking a suitable location for installation is another necessary consideration to be made. You have to ask yourself- will my tankless water heater be accessible for maintenance or seamless troubleshooting where it is? Does this location comply with local building codes? Etc. If you can answer these questions in the affirmative, your Noritz tankless water heater may be in the appropriate location.
Step 3: Prepare Utilities such as;
Gas Supply: Confirm that you have an adequate gas supply line with the correct pipe size and pressure rating. Following local codes and regulations, install a sediment trap and a shutoff valve.
Water Supply: Provide a dedicated cold-water line with isolation valves for the tankless water heater. Consider using a 3/4-inch line for optimal flow.
Electrical Connection: Ensure you have the correct electrical voltage and amperage. Follow the manufacturer’s instructions for wiring the unit to a dedicated electrical circuit.
Step 4: Install a venting system
Determine the appropriate venting type (direct vent or Category III stainless steel vent) based on the model and your home’s layout, and install it appropriately according to the user’s manual.
Step 5: Mount the water heater and connect the utilities
In this step, all you have to do is to mount the water heater and connect all the utilities.
Step 6: Install condensate drain
If your model requires a condensate drain, follow the manufacturer’s guidelines to install the drain pipe. Ensure proper slope and termination of a suitable drain system.
Step 7: Test and check for leaks while you perform initial startups.
Right before the initial startup you have to perform certain tests. Carefully check the leaks. If you are satisfied with the test then move on otherwise fix that first.
How To Flush a Noritz Tankless Water Heater
A Noritz water is great in its performance. Indeed, it possesses some interesting features that give you your money’s worth; however, when necessary maintenance measures are not taken effectively and regularly, you may soon experience a dip in performance. One of the maintenance measures you must regularly implement is flushing your tankless water heater to clear off debris and mildew that may be stuck on the water heater. Follow the step-by-step guide below to flush your Noritz tankless water heater.
Step 1: Turn off the power
Do not try to be a hero without first considering your safety. Your safety should always be primary when you flush your water heater. Go to the breaker that turns your unit on and off and put it off. You may also disconnect the power cord and follow the safety precautions prescribed in your manual for further necessary safety measures.
Step 2: Shut Off the Water Supply:
If water finds its way into your unit while flushing is on, it may disturb the process. Hence, shut off the water supply to the unit by turning off the valve on the cold water line leading to the water heater. This will prevent water from entering the unit during the flushing process.
Step 3: Prepare Flushing Solution
Prepare a descaling solution by mixing white vinegar and water in a 1:1 ratio. For example, mix equal vinegar and water in a bucket or container. This method is also quite effective for removing grease and stains from a stainless steel appliance.
Step 4: Connect Noritz Flushing Kit
Noritz flushing kit usually comprises a hose, a circulation pump, and other items found in an appliance repair kit, like a screwdriver, a wrench, etc. Hence, follow your user’s manual to determine how to connect the flushing kit to your tankless water heater, as they vary according to models.
Step 5: Open Service Valves
Locate the service valves on the tankless water heater. These are usually located near the isolation valves. Open both service valves to allow the descaling solution to flow through the unit.
Step 6: Start the Circulation Pump
If your flushing kit includes a circulation pump, turn it on to initiate the flow of the descaling solution through the tankless water heater. Ensure the solution is circulating through the unit and all the internal components. To allow thorough circulation throughout the internal parts of the water heater, you may wait it out for about 40 minutes and rinse it out with fresh water.
Step 7: Shut service valves and reconnect the water supply
Now in this step shut all the service valves. After that reconnect the water supply to move to the final step.
Step 8: Final Inspection
This is the final step. Once you find everything is as per the guidelines and working fine and you check for leaks or other latent faults now all you have to do is to restore the power.
