Sir, Is ISI mark compulsory. I have got brand new pigeon glass top stove as a gift for my new house costing around Rs. 4000/- . Glass top will never have a ISI mark. My sister is using the same type of stove form past 1.5yrs and its perfectly fine. I am not in a position to by a steel gas stove. I have already paid 250/- for the gas stove check and the guy mentioned that all gas is new and the nob all are good. He says that it does not have a ISI mark. Also, I was not told that there is such a requirement. Now I cant even replace it. The agency is asking to by gas stove from them as its ISI marked but the quality of the stove is not worth ~Rs. 3000/-. Can you please advise the course of action that I am suppose to take.
