Its in line with site glass, there are multiple spots where wires are burnt, and melted plasticDoes the wiring insulation look melted or black and burnt? Melted something shorted out pulling enough amps on small wires to overheat them. Burnt isn't that burn hole in cover in line to burner sight glass?
nope broken right offGlass intact?
Burner either overfired , delayed ignition or burning really crappie ( just like the fish) making the glass fail.
Went and looked at this wall hung boiler. Lots of wires inside are cooked too. What would cause this
I have no idea what happened above, but I have been running a Navien in my home for about eight years, and just installed one for my daughter last month. The only thing I have done with mine is clean out the incoming screen on the air intake two years ago. I'm on Woodinville city water which is pretty clean.

And just because you did not experience the above does not mean there isn't an issue with these units. Hope this is a fair statement.I have no idea what happened above, but I have been running a Navien in my home for about eight years, and just installed one for my daughter last month.

Probably not it wouldn't be flame failure burner is running with delay ignition, flue temperature limit 230* for 10 seconds before it trips, if burner was burning dirty flue temperature is down and flame might be wiping the glass. Without tearing heater apart its only a guess.Wouldn't there be error codes
This is awkward, but...
