Based on standard test procedures outlined by DOE for individual boilers.
Net AHRI ratings are based on piping and pickup allowance of 1.15.
Consult WM Technologies Technical Services for other allowances.
Foundation sizes in Figure139,page138 provide 6 inches between boilers and 2 inches from boiler to edge of foundation.
Smaller foundations are possible with reduced service clearances.
See page58 for details.
• For side-to-side installations, see Figure56,page58.
• For back-to-back installations, see Figure57,page58.
Operating weight is the total weight of the boiler, including water.
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 Figure59,page59, for manifolded air piping.
