        • Hi, we apologize but we are not able to understand if 61 cm is the size of your kitchen chimney space or the size of your kitchen hob space.
          If it is the size of your kitchen chimney space, then go with a 60 cm kitchen chimney. If 61 cm is the size of your hobb space, then go with a 2 or 4 burner kitchen hobb. Hope this clears it out. If not, please elaborate your query.
