ADDITIONAL CONSIDERATIONS
Always keep the area around the Pizza Oven free of obstructions and debris. Maintain at least 3” [7.5
cm] of space around the Pizza Oven to ensure proper airflow, and keep all ventilation openings in your
enclosure (island) clear and free of debris. Clean the appliance after each use, and check for blockages,
especially at the burner orifices, after periods of prolonged non-use. To maintain the appearance of
your Hestan Pizza Oven for many years, keep it covered when not in use. Backyard environments are
harsh on your appliance’s finish. Long exposure to sun, water, yard chemicals and the elements could
diminish the appearance of the stainless steel. This is very evident in ocean-front locations.
Our appliance materials have been tested in saline solutions with higher salinity than seawater. They
have also been tested by exposure to highly acidic foods. During and after these tests, we found these
materials were able to withstand exposure over prolonged periods of time. However, the above-
mentioned corrosive substances, along with neglect, can lead to a situation whereby conditions might
combine to cause some damage to occur. Therefore, we suggest that you always keep your Pizza
Oven clean, dry and covered when not in use. This is even more important when long term storage is
required. Always store the Pizza Oven clean, dry and covered with your Hestan Pizza Oven cover. A
dirty Pizza Oven will attract insects and rodents which is highly unsanitary. In addition, rodents are
known to chew on the insulation of wiring which will cause permanent damage to the wiring and
possibly electrical components.
For those in desert communities, wind-driven sand is highly abrasive and constant exposure will
eventually pit and scratch the surface. Another reason to keep your Pizza Oven covered when not in
use.
