I have seen this negative pressure actually cause boiling even when the water is nowhere near boiling." I have seen this happen and what it is a partial vacuum is being created and the water at around 180 in the vacuum flashes to steam, steam occupies 1700 time more space than water hence the gurgling and increase in pressure.
The gas pressure in the chimney needs to be less than atmospheric pressure in the boiler room for gases to leave. This sketch of a barometric damper used on oil fired heating equipment (heating boilers or water heaters) is provided courtesy of Carson Dunlop Associates.
