Dunkirk q90-100

Please help. I have a q90-100. Live in chicago. Weather is pretty cold. I cannot find anyone that really knows how to troubleshoot this type of furnace/boiler. I will attach a video to show what it's currently doing. It is short cycling and struggling to turn on

    There are a few options.
    1. Try the Find s contractor link above
    2. Call the manufacturer's tech support number
    3. Go to the local plumbing supply house where the installer might go for parts. Ask which of their customers they have that is good with trouble shooting and repair of this equipment. The local suppliers know who is good qt this stuff.
