    what the normal temperature of the flue collar should be?

    Hi,
    I noticed that flue collar temperature is about 200F when my HVAC Carrier 58UHV is working.
    1. What should be the normal flue collar temperature?
    2. What is the temperature when blocked vent safeguard switch trips over?

    Mine does it about once or twice a season but since it works for months between these failures I am not sure if this along signifies a serious issue to be treated immediately or if I can wait another year and then just ask the technician to investigate this during a regular inspection.

    call a contractor, you most likely have flue issues.
