Utica Boilers JE 安装指导

Base Assembly
300, 400 and 500 boilers are the basic models. 

• 300 model has (6) burners
• 400 model has (8) burners
• 500 model has (10) burners 

Combinations of basic models are used to assemble 600 

through 1500 models. 
Refer to Chart 3 for proper order of assembly. When two or 

more bases are used to assemble boiler, verify tops of bases 

are even. 

Fasten bases together with 5/16 cap bolts and nuts. 

Insert two bolts in front posts and two in rear posts as 

shown in Figure 7A . 

After bases are fastened, install base end panels. 

Install end panels before assembling sections. See 

Figure 7B.   

Verify bases are level after assembly.

Start sections from left or right end of base. 

Place end section on base with center-line of section 

directly over joint of base end closure. 

With boilers having two or more bases, as you progress 

be sure parting line (center-line of section) of intermediate 

sections fall on junction of two bases.  See Figure 8.

Note: First 

Section Alignment 

is critical. Use side 

of base to align 

first section. Do 

not allow side to 

overhang base.
