LIFTING LUGS
(3 POSITIONS)
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 Boiler utilizes 4" 150# flanges for the water system supply and return piping connections.
The physical location of the supply and return piping connections are on the rear of the unit as shown in
