Yes. There are different types of gas valves depending on the method of opening etc. As well as the dangers of leaks/explosions/liabilities/family safety etc it is best to get a licensed gas fitter to do it.
Some things You will need to know....the voltage, does it open in stages or all at once, inlet outlet size. how many BTU'S are needed for the boiler. If you install this. check for any gas leaks & the operation..
