3. Blower
The advanced blower design and air inlet silencer on ECO Wall
Mount boilers result in very quiet operation.
Air enters the boiler enclosure through the air intake adapter (16),
flows through the enclosure, enters the air inlet silencer (5), then
enters the blower. The blower pulls air through the silencer and
pushes it into the venturi (6), where it mixes with gas before enter-
ing the burner (11).
'ASVALVE
The automatic gas valve senses the vacuum in the venturi (6) caused
by flowing air and allows gas to flow when power is applied. A
manual gas valve is shipped loose with the boiler. It allows shutting
off the gas supply for servicing or shutdown. See instructions in this
manual for manual gas valve installation.
!IRINLETSILENCER
The horn-shaped air inlet silencer significantly reduces fan noise,
providing exceptionally quiet operation.
6. Venturi
When air flows through the venturi, it creates a negative pressure.
This vacuum pulls gas from the gas valve (4). Gas will only flow
if air is flowing. The gas mixes with air in the venturi. The gas/air
mixture then flows into the burner (11).
3UPPLYWATERTEMPERATUREDUALSENSOR
This dual sensor monitors boiler outlet water temperature. The ECO
control adjusts boiler firing rate so the outlet water temperature
is correct, based on the calculated (if outdoor reset used — see
page 119) or fixed target temperature.
2ETURNWATERTEMPERATURESENSOR
This sensor monitors return water temperature. The ECO control
reduces or increases boiler input, depending on how close the return
water temperature is to the outlet water temperature.
%LECTRONICDISPLAYBUTTONS
The electronic display is used to configure boiler settings and
monitor boiler operation. The buttons allow changing display mode,
selecting and adjusting control settings, and resetting the control
after lockout. This display can be mounted either on the boiler (as
shown) or on the wall.

"URNERNOTSHOWN
Made with high-grade stainless steel construction, the burner uses
pre-mixed air and gas. The burner and control provide modulat-
ing firing.

'ASCONNECTIONPIPE
Manual gas valve is shipped loose. Other ½” NPT gas connection
pipe and fittings external to boiler must be supplied by the installer.
#ONTROLMODULE
The control module responds to signals from the room thermostat,
DHW aquastat (if used), boiler sensors (boiler return, boiler supply,
flue temperature, and outdoor temperature, if used — see page 119).
The control automatically adjusts blower speed (and gas flow rate) to
match boiler output to space heating and/or DHW heating demand.
The control provides for one heating zone and one DHW zone.
!IRINTAKEADAPTERlTSv06#
A%LECTRICALENTRANCESLINEVOLTAGE
The top left side knockouts are designated for line voltage wiring
only. Ensure all wiring entrances are sealed.
B%LECTRICALENTRANCESLOWVOLTAGE
The top right side and bottom knockouts are designated for low
voltage wiring only. Ensure all wiring entrances are sealed.
"OILERDRAINVALVENOTSHOWN
Shipped loose for field piping. Pipe drain valve on reducing tee
at the lowest point of return piping to boiler. See instructions in
this manual.
#ONDENSATETRAPNOZZLE
The outlet at the bottom of the condensate collection dish. This is
where condensate is discharged from the boiler. The condensate
trap assembly attaches here.
&LUEGASCONDENSATEDRAINTRAPASSEMBLYNOTSHOWN
The condensate trap assembly is field-installed, connected to the
condensate trap nozzle as shown in this manual.
*ACKETDOOR
The jacket door is sealed to the boiler assembly around its entire
perimeter.
*ACKETDOORSCREWS
Two screws secure the jacket door in place.
)GNITIONELECTRODEmAMESENSOR
The burner flame is ignited by applying a high voltage to the igni-
tion electrode. This causes a spark (from electrode to ground). After
ignition, the electrode measures flame signal.
&LAMEINSPECTIONWINDOW
The quartz glass window provides a view of the burner surface, the
flame, and the ignition electrode.
&LUEGASDUALSENSOR
This dual sensor monitors the flue gas exit temperature. The ECO
control will shut down the boiler if flue gas temperature gets too hot.
This protects the flue pipe and the heat exchanger from overheating.
'ASVALVEREFERENCEHOSEONLY
This rubber line connects the gas valve diaphragm reference
chamber to the venturi intake to insure the valve senses the correct
reference pressure.
4RANSFORMER
The 120V/24V transformer provides 24V to low voltage control
circuitry.
Do NOT splice wiring into transformer.
!IRBAFmE
The air baffle protects internal boiler components by diverting any
incoming moisture or debris away from critical components. It
must be temporarily removed while servicing the heat exchanger.
