Weil Mclain Ultra Boiler, E 02 error and water dripping out of intake snorkel

I realize this is an old thread. I was wondering if OP had any resolution to water dripping out of the intake snorkel as I have the same problem with an Ultra 155 Series 2. Outside air and exhaust are through Weil Mclains vent (same as the one in the picture). However this is mounted up 10 feet from the ground with no inside corners or other encumbrances. This problem has been going on for a long time, it existed when I bought the house 16 years ago. Boiler throws E 02 codes occasionally, especially when weather is cold. (In fact I set up a remote reset function so i can reset when away from the house.) Weil Mclain tech support when told of this said "that's impossible". Is it water in the propane? Any help or insight greatly appreciated.

Your issue is your issue. It would be best to start your own thread, or describe your particular situation and history. Make and model boiler. Pics are good. Show venting inside and out.
