The first note is that every time I connect the cylinder, it's empty within 3 weeks. The oven itself is clean. Perhaps the problem is with the cylinder's regulator. I even brought a repair technician, and the oven is fine and working, it just needs cleaning from the back. As for the electricity, I haven't tried connecting the oven since I bought it. It's for sale to the highest bidder. Contact via Haraj or via the mobile number provided: (Mobile number appears when you click the contact button). Please, only serious buyers.
