V Knockdown Boiler Assembly Instructions A. Prior To Assembly 1) Thoroughly inspect the cast iron heat exchanger sections for any shipping damage, i.e. cracks in the castings, broken lugs or punctures due to mishandling. 2) Do not use a damaged heat exchanger section. Replace it with an undamaged heat exchanger section. 3) Keep the base in the shipping carton until it is time to perform the assembly. This keeps foreign material from contami- nating the burners or creating other hazards. Do

C. Section Assembly 1) Clean the boiler sections inside and out to remove dirt due to shipping and handling. 2) Clean all nipples and nipple ports with kerosene immediately prior to section assembly. 3) Set the left end section on the base so that the locating lugs on the bottom of the section go inside the front and rear base panels. Left end sections are identified by “LEH” cast on the section. Right end sections are identified by “REH” cast on the section. 4) Apply the Loctite 592 lubricant/s

NOTE Installation of the draft hoods will be easier if one person supports the rear of the hood while another installs the carriage bolts, nuts and washers. 6) Hang a rear tie rod channel bracket on the 4" stud installed in the left end section (Figure 12a). 7) Facing the rear of the boiler, find the square mounting holes underneath the draft hood. Drop a 5/16 x 5" carriage bolt through this hole and through the hole in the rear tie rod channel bracket. Loosely secure with a wing nut and washer
