A.

Requirements

CAUTION

•A mechanically driven ventilation system is REQUIRED for gas oven installations.

•A mechanically driven ventilation system is STRONGLY RECOMMENDED for electric oven installations.

PROPER VENTILATION OF THE OVEN IS THE RESPONSIBILITY OF THE OWNER.

B.Recommendations

NOTE THAT THE HOOD DIMENSIONS SHOWN IN FIGURE 2- 2 ARE RECOMMENDATIONS ONLY. LOCAL AND NATIONAL CODES MUST BE FOLLOWED WHEN INSTALLING THE VENTILATION SYSTEM. ANY APPLICABLE LOCAL AND NATIONAL CODES SUPERSEDE THE RECOMMENDATIONS SHOWN IN THIS MANUAL.

The rate of air flow exhausted through the ventilation system may vary depending on the oven configuration and hood design. Consult the hood manufacturer or ventilation engineer for these specifications.

To avoid a negative pressure condition in the kitchen area, return air must be brought back to replenish the air that was exhausted. A negative pressure in the kitchen can cause heat- related problems to the oven components as if there were no ventilation at all. The best method of supplying return air is through the heating, ventilation and air conditioning (HVAC) system. Through the HVAC system, the air can be temperature-controlled for summer and winter. Return air can also be brought in directly from outside the building, but detrimental effects can result from extreme seasonal hot and cold temperatures from the outdoors.

NOTE: Return air from the mechanically driven system must not blow at the opening of the baking chamber. Poor oven baking performance will result.

C.Other ventilation concerns

•Special locations, conditions, or problems may require the services of a ventilation engineer or specialist.

•Inadequate ventilation can inhibit oven performance.

•It is recommended that the ventilation system and duct work be checked at prevailing intervals as specified by the hood manufacturer and/or HVAC engineer or specialist.

This innovative oven combines cutting-edge technology with user-friendly features, making it an ideal choice for restaurants, pizzerias, and foodservice operations that demand efficiency and speed.

One of the standout features of the PS300F is its patented airflow technology. This system is designed to circulate hot air evenly throughout the cooking chamber, which helps create a perfectly baked pizza with a crispy crust and thoroughly cooked toppings. The even heat distribution ensures that every inch of the pizza receives the same level of cooking, reducing the chances of hot or cold spots that can affect the overall quality.

The PS300F is equipped with a double-deck design, allowing for increased production capacity without requiring additional floor space. Each deck can accommodate multiple pizzas at once, making it an ideal choice for busy establishments where speed is crucial. Operators can load pizzas into both decks simultaneously, significantly reducing cooking times during peak hours.

Another key characteristic of the PS300F is its digital control panel. This user-friendly interface allows operators to set precise cooking times and temperatures, ensuring optimal results every time. The oven also features programmable settings, enabling users to save specific cooking parameters for different types of pizzas, simplifying the process during high-volume service.

Energy efficiency is another important consideration in the design of the PS300F. The oven is constructed with high-quality insulation to minimize heat loss, contributing to lower energy consumption. This makes it not only an environmentally friendly option but also a cost-effective choice for businesses looking to reduce their utility bills.

Durability is a hallmark of the Middleby Marshall brand, and the PS300F exemplifies this commitment to quality. Built with robust materials and designed to withstand the rigors of a busy kitchen, this oven promises longevity and reliable performance.

In conclusion, the Middleby Marshall PS300F is a top-tier pizza oven that brings together innovative technology, efficiency, and durability.
