SECTION II. DIRECT SUPPORT MAINTENANCE PROCEDURES
Instructions for removal and replacement of installed components are listed in a logical removal sequence as prescribed
by the Maintenance Allocation Chart (MAC). Procedures will include (as applicable) disassembly, cleaning, inspection,
reassembly, installation, and testing to return the heater to an operational condition.
Because this heater is used in many different installation configurations, power, fuel,
exhaust, and ductwork connections vary. Disconnect as required.
