I have a Navien CH-240 NG combo boiler. The trouble I am having to every time we get the slightest bit of snow on the outside air intake plastic pipe the sensor in the boiler senses that there is a obstruction and automatically shuts the boiler down. This has happened serveral times and now we are afraid to leave our house overnight.. The boiler is only a year old and my local installer has no answers for me. Please help.
