I could be wrong, and usually are 
But Most combi's now are of a moduluating type! Overgassing doesn't present a problem as zero governor on gas valve, or pressure regulator on standard gas valve regulates gas pressure to operating requirements! Over gassing tends to give a you a boom (possibly flying flue terminals and sharpnel on isars, icos etc ) and slight bending of boiler casings upon combustion. A high limit/over heat stat activates at a set temp. Over gassed/ under gassed the stat still works at it's fail safe point. Thats it's job
