GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

To ensure that the assembled sections will be centered

Figure 33

Front View - Odd Numbered Models

on the burner base the cast iron sections should be

 

 

assembled from the midpoint of the burner base outward.

 

 

On boilers having an even number of sections the first

 

 

intermediate section should be placed so it’s side surface

 

 

lines up with the midpoint marked on the burner base

 

 

front and rear panels, Figures 31 and 32.

 

 

For boilers having an odd number of sections, the

 

 

centerline of the first intermediate section should line up

 

 

directly with the midpoint marks on the burner base front

 

 

and rear panels, Figures 33 and 34.

 

 

Refer to Table 3 for the location of the intermediate

 

 

sections with steam riser tappings, the flue collector

 

 

brackets and the front jacket channel bracket. With the

 

 

rope seal in place set the first section on the base making

 

 

sure that the section is supported and will not fall over.

The large top port should be above the front of the burner

 

 

base, Figure 35. Set the hydronic seals from the X1 Box

 

 

in the port openings before carefully bringing the next

 

 

section along side of it, Figures 36 and 37.
