The desired air/exhaust flange location is specified at the time of placing an order by selecting the appropriate regenerator part number. For example, 4343-7-A/CRG/LF would select the Left Front location per above. However, for convenience in selecting alternative field piping arrangements, the plenum can be removed from the bottom of the regenerator housing and rotated (90 degree increments are recommended) to suit. This needs to be done prior to adding the heat transfer media to the regenerator.
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.
