Notes
1 As an Energy Star Partner, WM
Technologies has determined that
ECO
Tec 80, 110, 150 and 199 boilers meet
the Energy Star guidelines for energy
eciency.
NOTE: Adjusting boiler ring rate will
aect AFUE rating.
2 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 certied by AHRI. AFUE
is also know as Annual Fuel Utilization
Eciency or Seasonal Eciency.
3 Net AHRI ratings are based on net
installed radiation of sucient 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.
4
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
specied in this manual.
ECO Te c 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.
5 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 modications and automatically derates
itself by approximately 4% per 1000 feet
above sea level.
6 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 Section303ofthe
2007EnergyAct
, this boiler is equipped
with a feature that saves energy by
reducing the boiler water temperature as
the heating load decreases. is 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.
THISOVERRIDEMUSTNOTBEUSEDUNLESSATLEASTONEOFTHE
FOLLOWINGCONDITIONSISTRUE:
• An external energy management system is installed that reduces the boiler water
temperature as the heating load decreases.
• is boiler is not used for any space heating.
• is boiler is part of a modular or multiple boiler system having a total input of 300,000
BTU/hr or greater.
• is boiler is equipped with a tankless coil (not applicable to ECO Tec).
