PRESSURE REGULATION AND TESTING

The gas pressure to the appliance must be rated for each appliance while the burners are on. A suf- ficient gas pressure must be present at the inlet to satisfy these conditions. Refer to the table below for correct gas pressure.

Each appliance has been adjusted at the factory to operate with the type of gas specified on the rat- ing plate attached to the right side of the ap- pliance.

Each oven is supplied with a regulator to maintain the proper gas pressure. The regulator is essen- tial to the proper operation of the oven and should not be removed.

DO NOT INSTALL AN ADDITIONAL REGULATOR WHERE THE UNIT CONNECTS TO THE GAS SUPPLY UNLESS THE INLET PRESSURE IS GREATER THAN 14” W.C. (1/2 PSI) (37mbar).

The oven and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45kPa).

The oven must be isolated from the gas supply piping system by closing its individual manual

shutoff valve during any pressure testing of the gas piping system at test pressures equal or less than 1/2 psig (3.45kPa).

Prior to connecting the appliance, gas lines should be thoroughly purged of all metal filings, shavings, pipe dope, and other debris. After con- nection, the appliance must be checked for cor- rect gas pressure.

The Blodgett BC-20G is a high-performance gas convection oven designed for commercial kitchens, catering operations, and foodservice establishments. Recognized for its reliability and efficiency, the BC-20G stands out as a versatile tool that enhances cooking capabilities while ensuring consistent results.

One of its main features is the 20 cu. ft. capacity, which allows for large batches of food to be prepared simultaneously. This spacious interior accommodates up to five full-size sheet pans, making it ideal for bakeries and restaurants that require substantial baking or roasting space. The oven’s ability to handle various cooking tasks—from baking bread to roasting meats—makes it a key asset in busy kitchen environments.

The BC-20G utilizes a unique convection cooking system that circulates hot air evenly throughout the cavity. This technology ensures uniform cooking results, allowing food to be cooked quickly and efficiently. The built-in, adjustable, high-quality blower provides even air circulation, minimizing hot and cold spots within the oven, which ultimately leads to better browning and overall texture of the food.

The oven features an intuitive digital control panel, which allows users to set precise cooking times and temperatures with ease. It also includes a programmable timer that helps in maintaining consistency across different dishes and cooking styles. The adjustable humidity feature further enhances the cooking process by allowing operators to introduce steam when needed, which is particularly useful for baking delicate items like soufflés or crusty bread.
