Indeed, the most likely way you will cause injury with a boiler is to not correctly fit the flue such that combustion by-products are vented inside the building.

The class 2 flue blocks in my house went up through the bedroom above the baxi bermuda back boiler and allowed the buider to fit a rad only 2/3rds of the size of the one in the other identically-sized bedroom. After I added just an inch of celotex on the inside of the front (north) wall of this bedroom, even before I refitted the rad I noticed that even in really cold weather, that the heat from these flue blocks kept this bedroom comfortably warm.
