Notes
As an Energy Star Partner, Weil-McLain
has determined that
ECO Tec 80, 110,
150 and 199 boilers meet the Energy Star
guidelines for energy efficiency.
NOTE: Adjusting boiler firing rate will
affect AFUE rating.
Based on standard test procedures
prescribed by the United States
Department of Energy. Ratings also
referred to as CSA Output.
NOTE that only DOE Heating Capacity
and AFUE are certified by AHRI. AFUE
is also know as Annual Fuel Utilization
Efficiency or Seasonal Efficiency.
Net AHRI ratings are based on net
installed radiation of sufficient quantity
for the requirements of the building
and nothing need be added for normal
piping and pickup. Ratings are based on a
piping and pickup allowance of 1.15. An
additional allowance should be made for
unusual piping and pickup loads.
ECO Tec boilers must be direct-vented.
ECO Tec boilers require special venting,
consistent with Category IV boiler.
Use only the vent materials and methods
specified in this manual.
ECO T ec
boilers may be direct exhaust
vented with Kit option.
ECO Tec vent/air pipes can be either
2" or 3". An adapter is required for 2"
venting.
All vent and air pipe elbows must be sweep
elbows, NOT short-radius elbows.
Ratings shown are for sea level applications
only. For altitudes from sea level to 2,000 feet
above sea level, the
ECO Tec boiler requires no
modifications and automatically derates itself
by approximately 4% per 1000 feet above sea
level.
All of the boilers will automatically de-rate
as vent/air pipe length increases, due to the
pressure loss through the piping. For vent/air
pipe lengths less than the maximum, the derate
equals the value above (% Input derate vs. vent
length) times vent length ÷ 100, for all except
for the 199 - 2" venting. 199 -2" derate equals
13% times vent length ÷ 50.

IMPORTANT
In accordance with
3ECTIONOFTHE
%NERGY!CT , this boiler is equipped
with a feature that saves energy by
reducing the boiler water temperature as
the heating load decreases. This feature
is equipped with an override which is
provided primarily to permit the use of
an external energy management system
that serves the same function.
