SPECIFICATIONS
Thank you for choosing NANO!
Nano by Zio-Ciro is a very light professional performance gas oven, ideal for residential use, with top and dome entirely made of
high quality refractory concrete.
Like a traditional wood-burning oven, once the cooking temperature has been reached, it is maintained for a long time, even after
the flame is extinguished. Nano is entirely insulated with high-density ceramic fiber and is a ready-to-use oven.
Ideal for cooking Italian-style pizza, it is also suitable for cooking other foods such as meat, fish, vegetables and desserts. The
oven is very light, it can be transported and used even in small spaces and on terraces, outdoor kitchens or gardens. The gas
consumption is very low, it is equipped with a Made in Italy burner of 7 KW of power.
Use with LPG or Propane gas only. Use with methane gas or natural gas is not allowed.
It is also supplied with a pressure regulator kit, hose, clamps and wrench to tighten the cylinder.
The oven can reach a cooking temperature of 450 ° C (850 ° F) in just 15 minutes. It has a hob of 38 × 40 cm. It comes with a
very convenient front shelf in stainless steel that allows the pizza to be turned even outside the oven.
