Installed a jacuzzi tankless water heater when I turned it on it beeps and has an 11 in the display what does this mean and how do I fix it
The error 11 indicates that the burner did not ignite the incoming gas properly. Make sure that the gas valve is open (at the water heater and the meter/tank, depending on the type of gas). If you have propane, check that the tank isn't empty. Make sure that the water heater is properly grounded.
The other causes for the error may require a professional to check them out. Check that the water heater is compatible with your incoming gas. (Propane burners do not work with natural gas and the reverse is true, as well.) Check that the gas pressure available is high enough for the unit. (Tankless water heaters often need larger diameter pipes to bring in the gas than their tanked predecessors.) Check that there is no air in your gas lines. Make sure that the condensation collar was correctly installed on the water heater and that the vent pipe isn't too long. There are some DIP switches that need to be set depending on the installation; make sure that all of these are in the correct positions. Next the burner, the igniter and the solenoid gas valve need to be checked. The wiring for the igniter and the valve need to be checked. The burner cover has to be removed to check if the burners are properly seated. The burner plate has to be removed so that the burner surface can be checked for debris or condensation. The igniter has to be checked to see if it is operational. Finally, the solenoid valve needs to be checked for a short or an open circuit.
I hope this helps.
(I've also had to check the end of the vent pipes for blockages - animal nests in the summer or ice in the winter.)
