When i removed the box from the car which had been loaded by the staff of the good guys i realized the box was not sealed. When your recommended gas fitter inspected the contents he informed that there were several items missing(Manuals ,fittings, conversion jets, sealer and maybe other items) He did the best he could to get me going, but the jets he had were the wrong size. I returned to the store the next day and was given some jets from a gas stove which i have not had the time to change yet. If i wanted a manual i was informed to go on the internet and download it. After spending over 2000 dollars on the cooktop and installation i am disappointed.
