In addition to the other requirements of FC609, solid fuel cooking systems shall be operated and maintained in accordance with this section.
609.5.1 Cooking Operations
Unless otherwise approved by the Commissioner of Buildings, the burning of solid fuel in commercial cooking equipment, such as briquettes, mesquite, hardwood, or charcoal, shall be allowed only for purposes of flavor enhancement. Solid fuel shall be ignited with a match or other approved means. Combustible or flammable liquids shall not be used. Matches shall not be stored in the immediate vicinity of cooking equipment. Solid fuel shall be added to the fire in a safe manner and only in quantities that will not create a flame higher than required. Long-handled tongs, hooks and other required devices shall be provided and used in order to safely add fuel, adjust the fuel, position and control the fire without having to reach into the fire box. The room where solid fuel is stored or used shall be protected throughout by a sprinkler system.
609.5.2 Solid Fuel Storage
Not more than a one-day supply may be kept in the same room as the solid fuel cooking equipment or masonry oven or in the room with the fuel loading or clean-out doors. Solid fuel shall not be stored:
  1. within 3 feet (914 mm) of any portion of a solid fuel burning equipment, masonry oven or any other heating or cooking appliance.
  2. within 6 feet (1829 mm) of any solid fuel loading opening or door of the solid fuel cooking equipment or masonry oven.
  3. above any heating or cooking equipment, flue or vent.
609.5.3 Water Supply
A water supply with a flexible hose shall be readily available to solid fuel cooking appliances and masonry ovens to cool down any fire that becomes too hot and to completely extinguish any fire before leaving the premises. The water source shall be a fixed pipe system with a hose of adequate length to reach to the combustion and cooking chambers of the appliance. The nozzle shall be equipped with a manual shutoff device, and shall be of the type to provide a fine to medium spray. A full flow or strong stream shall not be used.
609.5.4 Spent Fuel
Spent fuel, ash, cinders and other fire debris shall be removed from the fire box at regular intervals, but at least once a day, and, once removed, shall not be stored indoors. Adequate long handle rakes, hoes, scrapers and shovels shall be provided for such removal. When being removed from the fire box, the spent fuel shall be wetted down and cooled with water from the required water supply. Metal containers with covers shall be provided for such spent fuel removal. Such metal containers shall be of a minimum 16 gauge construction and shall be limited in size to a capacity not exceeding 20 gallons (75.7 L), so as to facilitate easy handling by any employee assigned to the task and to enable such containers to easily pass through any door or passageway. The spent fuel shall be placed outdoors in a dumpster or heavy metal container used exclusively for this purpose and kept covered at all times. Such dumpster or container shall be kept separate from combustible construction, and stored combustible materials and combustible waste.
