Notes



Based on standard test procedures outlined by DOE for individual boilers.

Net water ratings are based on piping and pickup allowance of 1.15. Consult Weil-McLain Technical Services for other allowances.

Total amp requirement includes up to three circulators, not exceeding 2.2 amps per circulator.



Operating weight is the total weight of the boiler, including water.

Evergreen

220 vent/air pipes can be either 3” or 4” pipe.

Evergreen

299/300/399 vent/air pipes must be 4”.

All of the boilers will automatically de-rate as vent/air pipe length increases, due to the pressure loss through the piping. See

Figure123,page129 for details.

All Evergreen

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 Advanced Manual for manifolded air piping.
