viessmann vito 100 F4 error code

My 14 month old Viessmann desided to crap out on me on the coldest day this year! It's giving me an F4 error code. I figured I would post here while I research it. A voicemail has been left with my installer. In the meantime, does anyone have some advice or a service guy in the Oyster Bay area. Thanks.

    I found the manual about 5 minutes after my installer called back! He just left after replacing the ignition/electrode block. A huge ty goes out to Bob at Technical Heating.
