This was an exact replacement for the old one that lasted about 10 years. kzbin.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

The navien hot is hot but the honeywell heater box is cold along with above brass pipe. How to turn that on as when I called navien no help because I'm the home owner

Installed a new 240A2 with navicirc valve at distant sink. What is the settings on the machine internal vs external circulation? Right now there is no pipe entering the recirculating port on the water heater. Please help. Thanks

just wondering if running the recirculation all the time is a concern for the pump or system? Only reason I ask is that was a option shown on the menu of your video but the speaker didn't speak to it

Constant recirculation can erode copper water piping over time, causing pinhole leaks. For newer houses with all PEX water piping, the risk and electricity usage is pretty minimal.

How do I configure the HotButton recirculation to recirculate as long as the other modes when they kick on? The other modes recirculate until the return temp is 9F less than the hot outlet set temp, but the HotButton recirculates only until the return reaches 100F. Worst, it doesn't do this by default either, as the default settings have it running only ~10s; the farthest fixture setting has to be changed from the default of 30 ft to some high unrealistic value (200+ ft) in order for the HotButton recirculation to run long enough for the return temp to rise that high. Whatever formula it's using here to calculate runtime, it's broken, as it doesn't reflect reality. Edit: Found the solution to the HotButton issue. On my A2 model, turn on dipswitch 2 on the HotButton PCB to disable Energy Savings Mode, and it'll recirc like the other recirc modes. I called Navien Support, and they wouldn't tell me how. Had to google and do a bit of reading to find it. Navien, maybe you guys can also explain why you won't tell me how to configure my equipment to work the way other modes already work. Pretty infuriating how useless support is.

My unit is running cold water from time to time. It's brand new. WASN'T an issue a week ago. Should I set it to recirculation mode?
@stephenbonner32311 ай бұрын
My NPE-A2 ran perfectly fine using the recirculating system until the end of December. Unit was installed in the late fall of 2022. Now, in either recirculation mode, it no long works, pumping only at a minimum rate, taking 5 minutes or more to get water temp to the set 125 degree temperature. The Navien recirculating valve is installed by our dealership that sold us the tankless. They cannot figure out what the problem is. They claim the pump is working properly, and it does until they leave my home. I'm getting really frustrated and need help. No one has offered to replace the pump or the control board to see if that could be a problem. It is still under warranty. Please help me.

Trying to find a solution for the NPE-240a with external recirculation line. The unit was installed over 2 years ago, and dip switch setting is Sw1 & 2 are both on for Intelligent mode. Over the past 6 months, when the recirculation pump turns on, I get pipe tapping noise (like air in line), and are trying to figure out how to fix it. The unit was installed with all PEX lines and insulated. Additionally I wanted to ask if it's okay to lower the pump run time to 10 minutes vs. the default 20 minutes. Thanks in advance for your support.

Those are all changeable in the settings menu. Find the recirc settings and go through all of them. You will be able to address all of those.

If I use it in external circulation mode. Would it hurt the unit if I control the pump seperate from the unit. Would Turing the pump off cause it to over heat seeings that water movement would stop?
@marksplace Жыл бұрын
Basically I want to use an aquastat to control the pump without the machines knowledge. I know on some boilers it you turn the pump off while it's on will cause it to shake around due to the water boiling in the heat exchanger without any movement. Thanks

how is the hot water being returned in that loop? is there a dedicated 3rd pipe dedicated that needs to be tied in into faucets? or does it use the cold water line as return .

@brycemcguire94772 жыл бұрын
Unless you have a recirc pipe that is several hundred feet in length, 1" is very oversized. This could cause laminar flow, temperature fluctuations, and unnecessary work for your recirc pump.

What should you do when you have an external unit & when you plug in the recirculating pump it’s stays running and never shuts down. I added the smart plug as well and it’s shuts off but it’ll automatically turns on & off with no by itself with no water calling in the house. When it runs it stays on for awhile before it shuts off
@jbyers300510 ай бұрын
With an external pump it is controlled by the outlet it’s plugged into. The easiest way to address it is a timer that plugs into the outlet, and the pump plugs into the timer. Sounds like you got something similar. You should be able to turn it on or off in 15 to 30 minute increments.
