Just near Mannai R/a there is a big show room, selling all types of Ovens in the world. It is just near Bombay silk house. I think you cannot purchase the metal type Gas cylinder from the Truck gas distributers, because they stopped selling Metal gas cylinders. Just we can replace the empty Cylinder with filled one. I hope so. You can purchase plastic type Gas cylinder from Woqod Petrol Station near the Jaidha Tower. Regards
