MODERN BURNER UNIT (MBU)
OPERATION UNDER USUAL CONDITIONS
This section outlines the siting requirements of field feeding systems determined by the MBU power and
fuel requirements, as well as the installation, preparation, and operation of the MBU under usual
Read all warnings and cautions within this section and follow procedures outlined herein to ensure safe
operation of the MBU and associated equipment.
Siting of the field feeding system may be influenced by the power and fuel requirements of the MBU.
When using the primary power (110V AC) as with the MFK, MKT, and FSC, the power source must be
located within 50ft of the power converter. When a 24V DC power source is used as in the KCLFF, it
must be located within 25ft of the MBU (or battery pack, depending on the power configuration used). The
internal location/distribution of the burners within each field feeding system must be in accordance with
the prescribed layout for that system so that the 24V DC extension and branch cables can reach each
burner. In some cases, limited flexibility is possible or additional burners can be connected to the branch
cable end plug. Refer to the specific field feeding system technical manual listed in WP 0037.
ASSEMBLY AND PREPARATION FOR USE
Initial fielding and installation of the MBU and associated equipment into field feeding systems, including
application of modification work orders for the MKT, will be accomplished through contracting resources.
Subsequent MBU or component replacements received at the unit level do not require deprocessing and
can be used in the manner prescribed herein, after unpacking. Assembly is limited to the installation of
new batteries into the battery pack as described in WP 0031.
Before Operation Preventive Maintenance Checks and Services (PMCS) . Perform the Before
Operation PMCS on all MBU system components as outlined in WP 0010, prior to preparing the system
