IMPORTANT: Hot Dog Burners produce large amounts of heat which is transferred by convection and radiation. Care must be taken when positioning the burners under and along the sides of the cars to ensure that they will not overheat exposed equipment such as hoses, journal boxes, axles or brake cylinders. The trough support legs provide 1" clearance under the burner. This promotes cooling air circulation under the center burners and prevents charring of the ties. THIS SPACING MUST BE MAINTAINED. If there is a clearance problem between the burner and the car hopper, either cut a groove in the ties or elevate the rails in the thawing area to provide the required clearance. To allow for expansion and contraction of the burner due to tem- perature changes, the spikes or bolts through the mounting holes at one end of the trough should be a loose fit. The length of heating time and the burner firing rates necessary to thaw cars without overheating, are determined by operating experience. By monitoring the thawing process, programs may be developed which cover various circumstances, including weather conditions and how solidly the loads are frozen.

WARNING: Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
