Foundation sizes in Figure 126 provide 6 inches between boilers and 2 inches from boiler to edge of foundation.
Smaller foundations are possible with reduced service clearances.

Ultra-80 and -105 vent/air pipes can be either 2” or 3” pipe. Vent/air pipe length limits for 2” piping are not as long as for 3” piping.
Ultra-230 vent/air pipes can be either 3” or 4” pipe. Vent/air pipe length limits for 3” piping are not as long as for 4” piping.
All Ultra installations require a separate vent pipe and termination for each boiler.
Vent piping cannot be manifolded. Install and
terminate vents as described in vent/air installation instructions in this manual.
Combustion air piping can be individually piped or manifolded. See Figure 59, page 55, for manifolded air piping.
