20 Most Recent Noritz 6.9 Gallon Residential Tankless Water Heater - N-069M - Page 5 Questions & Answers

You are describing normal operation. Does it NOT work any other time? If so, go to your remote and hold in the up and down arrows at the same time and hit up until you find number 14. this shows the flow rate. your flow rate has to be above 005 in order for the unit to start. try running a bathtub. if this starts it the problem is your faucets not allowing enough water through them. if this doesn't start it then you probably DO have a cross connection and you just haven't found it yet. Especially if the unit is running but the water never gets hot. Either way, call Noritz for them to walk you through it and you'll get it working.

If the water is coming down over the fan motor, you probably have a heat exchanger leak. If the heat exchanger is leaking, it needs to be replaced. The heat exchanger is the large copper box on top of the heater.

Hi,
Is the vent going straight up???

If so maybe you can get a better cap or a 90 on there to keep the rain from coming in...

But it may also be a humidity problem and the higher humidity change the air fule mixture just enough to keep it from working...
