(Pressure always moves from high to low, we all know). In short, the pressure may be artificially lower within the boiler room/enclosure or artificially high outside the chimney exit, or a combination of both. Armed with that, the first things I look at are sources of negative pressure within the boiler room or affecting the boiler enclosure.

Operating Instructions Solid fuel boiler - bosch-climate.us

V Operate the boiler with a minimum return temperature of 131 °F. Ensure that this temperature limit is adhered to with a suitable set-up. V The minimum boiler water temperature must be above 131 °F, because with a lower temperature, steam can condense. This has negative consequences for the proper operation of the boiler and its life span.
