Benchmark 5000-6000 Boiler Installation & Startup Manual
SECTION 2: INSTALLATION
2.4.3 LIFTING PROVISIONS
Two (2) lifting lugs are provided at the top of the primary heat exchanger as shown in Figure 2-
4. The location of the lifting tabs is marked on the shrink-wrap coving the unit for shipping.
Remove the four (4) lag screws securing the unit to the shipping skid, and, if still in place,
remove the front Top Panel. Lift the unit off the shipping skid using a spreader bar and position
it on the (required) concrete Housekeeping Pad in the desired location.
WARNING!
When lifting or moving the boiler, do not attempt to manipulate the unit using the gas train or
blower. A spreader bar is required for all vertical lifts. Failure to use a spreader bar can put
excessive force on the unit and can cause boiler failure.
LIFTING LUGS
NOTE:
The front top panel must be
removed to access the front
lifting lug.
2.4.4 MULTIPLE UNIT INSTALLATIONS
In multiple unit installations, it is important to plan the position of each unit in advance. Sufficient
space for piping connections and future service/maintenance requirements must also be taken
into consideration. All piping must include ample provisions for expansion.
2.5 SUPPLY AND RETURN PIPING
The Benchmark 5000 and 6000 boiler utilizes 6" (15.24 cm) flanged fittings for the water system
supply and return piping connections. The physical location of the supply and return piping
connections are shown in Figure 2-5. Refer to Appendix A: Dimensional and Clearance
Drawings for additional dimensional data.
