New IN6 Boiler install

It's is cool enough for a trial operating cycle.
The old AS oil boiler was 640 sq ft, the IN6 is 450 sq ft. Same house of course is the same.

I noticed that the 1 psi pressure limit was reach much quicker - within the first 15 min of running, and the radiators were just starting to get hot. The old boiler would run for over an hour to reach the first pressure trip out.

Could it be that my two main vents are now too small?
