There is less of a concern with gas as the fuel, as it tends to never smoke unless there is a great problem. Oil can collect soot slowly and corrode the metal sooner with the sulphur content, also overfiring can wear the baffles. If you get a draft pressure gauge, you can see if the pressure before and after the baffles (chamber and chimney pressures) changes over time to see possible cleaning time and not make it necessary to open it every year. However, Peerless engineers made the recommendations because they have some concerns in mind, so it is usually best to follow recommendations. Peerless would do well to make such annual disassembly disappear.
Low-mass tube boilers need such refurbishment yearly as they can clog and burn without such reassembly. Your boiler is probably an oil burner boiler, (because it has a tankless coil) which needs annual combustion testing to establish that it will be dependable through the season. That includes a draft check. A worn baffle will change the air adjustment requirement. Keeping yearly records of draft and efficency can establish a trend. Cast iron boilers have been a standard because they didn't need such attention and could be left for a years. Times are changing.
