Section III. OPERATION UNDER UNUSUAL CONDITIONS

TM 10-7360-204-13&P Change 11 2-25 Allow the unit to cool before releasing the air pressure from fuel tank. Do not smoke, and make sure there is no open flame in the vicinity. c. Remove burner unit from cabinet and release fuel tank air pressure. To release air pressure, place unit in vertical position, and turn fuel filler cap slowly counterclockwise. d. Install the burner unit in the bottom burner unit position and secure with retaining bar. e. If the range outfit is installed as a multiple unit, and the equipment is to be moved some distance, separate the range into individual units and handle them separately. 2-9. REINSTALLATION AFTER MOVEMENT. Refer to paragraph 2-1 to reinstall the equipment. Section III. OPERATION UNDER UNUSUAL CONDITIONS 2-10. GENERAL. This section contains instructions for operation of the equipment in the following conditions: extreme cold, extreme heat, dusty or sandy areas, rainy or humid conditions, salt water areas, and high altitudes. 2-11. OPERATION IN EXTREME COLD (BELOW 0^oF). a. Initial tank pressure may need to be pumped until pressure reads 8 pounds per square inch (psi) as indicated on the air pressure gauge. b. Keep the fuel tanks filled with 8 quarts (7.6 liters) of gasoline or until fuel can be seen at the bottom of the fuel filler tube, when the burner unit is vertical and not in operation. This will help to prevent moisture from accumulating in the fuel tank. c. A flat rubber filler cap gasket must be used for cold weather applications. Filler Cap Gasket installation is an Organizational Maintenance procedure (paragraph 4-9.8). d. Adjust the air control shutter as required to insure a greenish color flame. e. Remove any accumulation of moisture at regular intervals. 2-12. OPERATION IN EXTREME HEAT. a. Never place more than 8 quarts (7.6 liters) of gasoline in the burner unit. The unit is properly filled when the fuel can just be seen at the bottom of the fuel filler tube. Overfilling does not leave sufficient space for expansion. During extreme heat tank pressure may be pumped to 3 to 5 psi on gauge. b. If the unit is to be operated indoors, provide adequate ventilation. c. Observe the air pressure gage often. 2-13. OPERATION IN DUSTY OR SANDY AREAS. a. Erect a protective shelter for the unit where possible. In temporary installations, take advantage of natural barriers. b. Where water is available, keep the immediate area wetted down. Keep the unit and accessories as clean as possible; pay special attention to the burner unit and utensils. c. Keep dirt and grit out of the fuel system and reserve fuel supply. 2-14. OPERATION UNDER RAINY OR HUMID CONDITIONS. When the equipment is operated outdoors, erect a shelter if possible. When not in use, the unit will be covered with canvas or other waterproof material. Remove the cover during dry periods, open the doors, and allow the unit to dry out. Keep the fuel tank filled with 8 quarts (7.6 liters) of fuel. WARNING
