Notes
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 Weil-McLain Technical Services for
other allowances.
Total amp requirement includes up to four
circulators, not exceeding 2.2 amps per
circulator.
Operating weight is the total weight of the
boiler, including water.
EVG 70 vent/air pipes can be either 2" or 3"
pipe.
EVG 110 and 155 vent/air pipes must be 3".
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 139 for details.
All EVG installations require a separate vent
pipe and termination for each boiler.
piping cannot be manifolded
terminate vents as described in vent/air
installation instructions in this manual.
Combustion air piping can be individually
piped or manifolded. See the Advanced
Manual for manifolded air piping.
