A:  I helped my ex-wife to have this installed in her home. Unfortunately, I have not kept up with any installation manual updates. However, the Westinghouse technical support team is very competent, and I'm sure they can help you. They actually have the water heaters installed in their office, for training and customer support services. The unit has been working perfectly, after the initial startup adjustments that must be made to insure high efficiency. That requires a competent HVAC technician with the proper exhaust gas measuring equipment, to achieve the desired results. Hope this helps. Warmest Regards; Rich

A:  I used the "HTP Phoenix Light Duty" documentation. This unit is made by HTP and relabeled for Westinghouse.

As you know, this Maker has absolutely ZERO to-do with our very old, famous USA Corporation ... instead, it is simply a "purchased" name only, in an obvious attempt to make potential Customers that they ARE actually One-in-THE same!! ZERO Customer Reps or Authorized Servicing Technicians or Dealer Organization, either. There's zero means in my own actual experiences to ever get an Answer / Reply / Clarification regarding their various South Korea Products! Apologies BUT, Thanks for your Question! .... eli2

A:  Upon installation mine initially sounded like it had a small train in it. Adjusted using a flue gas analyzer and noise went away. Had access to the analyzer and know how to use. If you do not have access call a pro. I have had mine for a little over a year. A month ago got a recurring unstable flame error. Called tech support and they were great and directed me to the problem which was totally different from the fix listed in the manual under the error code. You might give them a call if you have not.

A:  I helped my ex-wife to get this installed in her home. The exhaust should be extremely quiet "if adjusted properly". Unlike a conventional hot water heater, you can't just install it and turn it on, and expect it to work properly. A professional HVAC person with the proper exhaust gas measuring equipment is needed, to adjust it properly. This is probably the most efficient hot water heater on the market today. To achieve this high efficiency, it has adjustments to compensate for the incoming gas line pressure on your street, the altitude of the heater above sea level, the length of the incoming fresh air PVC pipe, and the length of the exhaust PVC pipe. All of these variables effect the heating efficiency of the burning gas. Your HVAC expert must have a Westinghouse technical support person on the phone, when the adjustments are being made. There is a very specific order to the adjustments, and your HVAC expert must relay the exhaust gas measurements to Westinghouse technical support, as the adjustments are being made. It can sometimes take a few hours, depending on the specific details at you location. Once adjusted, it should be very quiet and efficient. You only need to do this once, unless some type of problem develops in the future. This could be a change in the gas line pressure coming in from the street, or a problem with the gas pressure regulator and meter attached to your home. In my situation, it was noisy when first started, and the adjustments worked perfectly to where you almost can't tell when it's on. The supplied installation instructions reference the need and importance of the adjustments. It is most important that Westinghouse be on the phone when the adjustments are made, otherwise you will not achieve the quoted high efficiency. It's truly a remarkable design, that may be the last water heater you will ever need Warmest Regards; Rich

A:  I had a noise issue with my unit and it was caused by an unbalanced air intake pipe length vs exhaust. If you think this an issue you may need to add some elbows and pipe length to the intake. It made my unit very quiet.

A:  If it's making any significant noise it's not operating properly. The gas valve will need to be adjusted by a technician. Mine makes a noise similar to an engine, especially on start-up. I hope you have better luck than I in getting a tech to look at it. It shouldn't be a difficult job for them, but no one wants anything to do with these!

A:  You can try to make a exhaust muffler?!?! This thing sounds like a growing sputtering freight train when it runs! Weird thing is it is quiet inside the house, the noise is outside. YouTube has what you need to do to make a muffler just not sure how much noise it will silence.

A:  To: 'Stefan' dated Jan12th Re:{ Why is exhaust so very loud / how to silence?} Sir: In the accomplishment of these ultra-high Efficiency Appliances, it was mandatory to incorporate double combustion chambers - E.G. - there is the primary Chamber which we all understand as being THE location of the fuel being burned. BUT, now, there must be designed and incorporated a new, Second Stage which captures or receives the exhaust from that initial combustion, "wring-out" all of the heat energy which previously went 'UP 'n OUT" our chimneys! ...to accomplish all of that pushing of large volumes of hot gases inside any Ultra-Efficient Furnace, Boiler, or, in your instance, DHW Heater, there MUST BE a powerful blower to overcome the associated resistance. No, there is absolutely zero means of silencing your Water Heater w / o dangerously-affecting the design & operation of that Unit.....that is one reason that many are installed very remote from any Bedrooms, etc., far corner of attached Garage, etc......eli2
