Maximum operating pressure 60 psi.
All boilers hydrostatically tested — A.S.M.E.
* For forced hot water heating systems where the boiler and all piping are

located within the area to be heated, the boiler may be selected on the basis
of D.O.E. capacity output. The net AHRI output ratings shown are based on
an allowance for piping and pickup of 1.15 (water). D.O.E. capacity output is
divided by the allowance to obtain net rating. The Slant/Fin Technical Service
department should be consulted before selecting a boiler for unusual piping
and pickup requirements such as intermittent system operation, extensive
piping, etc.

† Ratings apply to the use of light oil at 140,000 Btu per gallon and apply only

when burner models listed on pages 8 of this manual are used, and are
properly adjusted to produce 13% CO2.

# All dimensions subject to normal manufacturing tolerance.
NOTE: All boilers under 300,000 Btuh (87.9 kw) input are tested and rated for

AROUND IT.

Provide a level, solid foundation for the boiler.
A. The foundation must be capable of supporting the weight of

the boiler when filled with water:

* Includes burner, circulator and controls

B. These boilers have full wet base sections which surround fire box for

maximum heat absorption of burning fuel, and low floor temperature.

C. The boiler can be installed on both combustible and non-combustible

floors, but must NOT be installed on or above carpeting.

D. If boiler is to be located over buried conduit containing electric wires

or telephone cables, consult local codes or the National Board of Fire
Underwriters for specific requirements.

MINIMUM CLEARANCE

Provide accessibility clearance of 24" from surfaces requiring servicing (top
and front) and 20" on any side requiring passage. The boiler shall be
installed with the following MINIMUM clearances from combustible materials:
BACK-6"
SIDES-2"
NOTE: Except in closets and alcoves, clearances above may be reduced by
providing forms of protection as specified in NFPA 31, latest edition.

VENTING REQUIREMENTS

CAUTION: AN OIL-FIRED UNIT SHALL BE CONNECTED TO

A VENT HAVING SUFFICIENT DRAFT AT ALL TIMES TO
ENSURE SAFE AND PROPER OPERATION OF THE UNIT.

• The terminal shall not be closer than 3 feet above or 10 feet horizontally
from any forced air inlet into the building.

• The terminal shall not be closer than 4 feet below, 4 feet horizontally
or 1 foot above any door, window or gravity air inlet into the building.

• The terminal shall not be less than 3 ft from an inside corner of an “L”
shaped building.

public walkways.

• The terminal shall not be less than 2 ft from an adjacent building.

• The terminal shall be located at a height not liable to blockage from leaves,
snow or other debris, at least 1 ft above grade or anticipated snow line.

• The terminal shall be positioned so that flue gases are not directed where
they can jeopardize people, overheat combustible structures or enter
buildings.

• Vent terminal should be away from shrubbery or other obstructions that
would prevent free air flow to and from vent terminal. Do not terminate vent
under decks, stairways or car ports. When ever possible, locations under
windows should be avoided.

• Vent termination should not be mounted directly above or within 3 ft
horizontally from an oil tank vent.

BOILER INTERNAL BAFFLES
IMPORTANT

: EC-10 series boilers Direct Vent version is different from
standard series. Direct Vent version boilers usually have fewer internal cast
iron baffles.

VENT PIPING

A. The vent piping minimum bend radius is 12”.
B. Place metal strapping every 36” to support vent pipe and

prevent it from sagging.

C. Maximum wall thickness is 14”. Contact Slant/Fin Corp. for

recommendations in case of thicker wall.

D. Gases will form white plume in winter. Plume could obstruct

window view.

E. Prevailing winds could cause freezing of condensate and water/ice

buildup on building, plants or roof.

F. Locate or guard vent to prevent accidental contact by people or pets,

and condensate from damaging exterior finish.

G. Do not terminate vent in window well, stairwell, alcove, courtyard

or other recessed areas.

All venting kits must be double wall construction for the flue gas piping. Field
Controls is the only approved manufacturer for venting kits. When installing
the vent kits the manufacturers instructions must be followed.

PIPING

IMPORTANT

: Boilers are to be used with closed system. Any application that

uses water from system, causes the introduction of a frequent supply of fresh
water into the boiler. This will cause damage to the boiler. Use of heat
exchangers will prevent this damage.

PIPING FOR WATER UNITS

NOTE: On knock down boiler only, jacket may be installed after return piping
connection, but must be installed prior to adding trim & supply piping.
I. CIRCULATING SYSTEM

A. FORCED CIRCULATION hot water heating system: Use the top
tapping as supply tapping, and use the rear bottom tappings for

the return.

B. A FLOW CONTROL VALVE will prevent gravity circulation.

II. AIR CONTROL SYSTEMS

A. DIAPHRAGM-TYPE COMPRESSION TANKS are used to control
system pressure in an AIR ELIMINATING SYSTEM: an automatic
air vent is used to REMOVE air from the system water. See figure 3.

EUTECTIC EC-10 DV

5

If system pressure needs further control, add an additional tank or install a
larger capacity tank. The automatic air vent should be installed in the top of
the boiler, as in figure 3.

B. CONVENTIONAL COMPRESSION TANKS (non-diaphragm type) are

used to control system pressure in an AIR COLLECTING SYSTEM. Within
the system, after initial start-up and venting, air is collected in the tank and
acts in contact with the water to control pressure. Air is not vented from this
system. If system pressure needs further control, add another tank in
parallel with the original tank or install a large capacity tank. Locate the
tank at the inlet end of the pump near the boiler. (See figure 3)

C. HOT WATER RADIATION VENTING - Manual air vents should be installed

at the top of all "drops" (where piping goes downward). Air must be vented
or purged from all zone lines to permit proper system heating.

D. PUMP LOCATION - Locating low-head pump(s) on return to boiler is

acceptable for smaller boiler sizes in residences of one or two stories.
The pump location shown in figure 3 is required in large, multi-story
building installations, especially when high-head pumps are used.

IMPORTANT: Hot water heating systems containing high water volume, such
as would occur with cast iron radiation, require special care with air elimina­tion. The circulator pump should be located on the boiler supply pipe and the
expansion tank and air scoop should be located near the pump suction.

INSTALLING THE BURNER

See Burner Data, pages 12-13, and Burner Manual supplied with burner. If
burner is not mounted as received, mount to boiler, placing flange over
mounting studs. Use gasket between flange and boiler. Distance between
flange and nose of burner must be as shown in table on page 12 (Burner
Insertion Depth). Check to see that nozzle and settings are as given in burner
data tables, pages 12-13.

OIL SUPPLY PIPING

Install the oil tank or tanks and piping from tank to burner. Follow local
codes and practices, NFPA No. 31, INSTALLATION OF OIL BURNING
EQUIPMENT and the instruction sheet attached to the oil burner pump. A
one-pipe system should be used for gravity fed fuel systems and for lift sys­tems, where the total lift is less than 8 ft. Where the total lift is greater than 8
ft., a two-pipe system must be used. In some instances, local codes may
require a two-pipe system for below grade fuel oil tanks. Be sure to set-up
the fuel oil pump for the piping system used; follow the instructions attached
to the pump. Be sure to include a good quality, low pressure drop fuel oil fil­ter in the supply line from the tank. This is necessary, especially at low fuel
oil flow rates (small nozzle sizes), to prevent nozzle plugging.

WIRING THE BOILER

• The wiring diagrams for the burner and boiler may be found on pages 7-10.

• 24 volt control wiring should be approved Safety Circuit wire, protected
as needed.

• Power supply wiring to the burner must be 14 gauge or heavier, as
required, and should have a properly fused disconnect switch. 120 volt
wiring to pumps and safety controls must also be 14 gauge or heavier.
Wire must be enclosed in approved conduit.

• All wiring must be installed in compliance with the National Electric
Code, or any local or insurance codes having jurisdiction.

Wiring to the boiler must come through an emergency power
isolation switch with a clearly marked red switch plate. This
switch should be located so that it is apparent to the home­owner when entering the basement or other boiler area. The
homeowner should be made familiar with operating the toggle
to provide or stop the power to the boiler.

PRECAUTIONS BEFORE STARTING OIL BURNER

C. Oil supply is connected to the burner; nozzle is installed correctly; oil

valve is open at tank.
D. All combustible materials are cleared away.
E. All vent piping is properly installed and sealed.
F. Burner settings are adjusted as per pages 12-13 and as shown on

boiler jacket label.
G. Main cast iron door on which burner is mounted is bolted shut and

fiberglass rope seal is making good contact.
H. Make sure boiler has correct quantity of baffles (see top of page 3).
I. Make sure vent pipe, vent terminal and air supply pipe are properly

installed and clear of obstruction.

Note: Neither overfire nor flue draft should
exceed 0.35" WC during burner operation

THE FLUE IS UNDER POSITIVE PRESSURE DURING

OPERATION. ALL VENTING MUST BE SEALED AND

CHECKED ON A REGULAR INTERVAL.

OPERATING INSTRUCTIONS

CLEANING AND FILLING A NEW WATER BOILER

I. BEFORE FILLING WATER BOILER

A. Check burner to be certain it is ready for firing. DO NOT FIRE

into an empty boiler.

B. Be prepared to heat raw water to at least 180°F. as soon as it is

introduced into the boiler. This procedure will remove dissolved,
corrosive gases.

C. Provide drain line, with valve, from boiler. Use a bottom tapping.

Line and drain must be suitable for handling caustic solution.

II. CLEANING WATER BOILER SYSTEM

A. Use a commercial cleaning solution, such as Rhomar Hydro-Solv

9100 Cleaner as directed in product instructions.

B. Use a commercial treatment solution, such as Rhomar Pro-Tek 922

Treatment as directed in product instructions.

III. FILLING AND VENTING THE WATER BOILER

A. Refill the system with fresh water.

B. Bring water temperature to at least 180° F. promptly.
C. Circulate water through entire system.
D. Vent the system, including the radiation.
E. The boiler is now ready to be put into service or on standby.
F. If brand-name air-control devices are used, venting instructions
furnished with the devices should be followed.

IV. SAFETY CHECK FOR CONTROL SYSTEM

High limit control test: Set thermostat high enough for boiler water
temperature to reach high limit control setting. When this temperature is
reached, the high limit switch should open, and the burner should shut off
automatically. If the high limit does not operate to shut off the burner, the
high limit or the wiring is faulty. Repair or replace immediately.

START-UP (COMBUSTION TEST INSTRUMENTS MUST

BE USED) THIS BOILER IS A POSITIVE PRESSURE BOILER

.

SETTING THE AIR DAMPER ADJUSTMENT (see figure 7 & picture 2)

1. The initial air damper setting is made by turning screw (2) until the top edge of the air damper (3) is aligned with the
number according to the burner setup chart.

2. Further adjustments can be made with the burner cover in place by removing plastic plug on the top right hand side
of the cover. Turn the screw counter clockwise (+ indicator) to increase combustion air, turn the screw clockwise ( ­indicator) to decrease combustion air.

3. The final position of the air damper will vary on each installation. Use instruments to establish the proper settings
for maximum CO2 and a smoke reading of trace to zero.

NOTE: Variations in flue gas, smoke, CO2 and temperature readings may be experienced when the burner cover
is put in place. Therefore, the burner cover MUST be in place when making the final combustion instrument
readings, to ensure proper test results.

CARE AND MAINTENANCE

I. EXTENDED SHUTDOWN, CLEANING OR REMOVAL OF

BOILER FROM SERVICE.
DANGER: Use CAUTION when handling chemicals and
draining hot water from a boiler. Scalding water and/or
chemicals can cause permanent injury to the skin, eyes
and respiratory system.
A.Shut down burner by disconnecting all electrical power to

the burner by turning OFF the BURNER EMERGENCY
SWITCH of this boiler. After shutting down burner, while
the boiler is still hot (180°F to 200°F), drain water from
the bottom of the boiler until it runs clear.

B.Provide corrosion protection conditioning to the boiler water

in the heating system. There are a number of commercial
heating system preparations available from your distributor.
Follow the preparation manufacturer’s instructions.

C.To clean the fireside boiler surfaces, first shut down

burner by disconnecting all electrical power to the burner
by turning OFF the OIL BURNER EMERGENCY
SWITCH of this boiler in order to perform the following
work in (1) through (10) below.

1. Remove the flue pipe from the boiler flue collar and
clean thoroughly.

2. Inspect the entire vent connector back to the chim­ney and clean if necessary.

3. Inspect the chimney for soot, debris and other unsafe
conditions of the chimney and take the necessary
action.

4. The burner mounting door must be fully open to
clean the flue passages and the combustion
chamber. If the oil line is not flexible enough it should
be disconnected from the burner during the cleaning
process. The flexible electric conduit connected from
the junction box on the boiler to the burner via a
plastic connector must be disconnected from the
burner by grasping the plastic half of the connector
closest to the flexible conduit and gently pulling it in
the direction of the conduit until it is disconnected.
Remove all four 13 mm hex head screws on the
sides of the swinging door. You will need a 13 mm
open end or box wrench. Open the door to
completely expose the combustion chamber for
thorough cleaning and for inspection of main cast
iron burner door insulation and burner door fiberglass
sealing rope.

5. Use the flue brush to clean the flueways. Remove cast
iron baffle plates for cleaning [(2) baffle plates in EC­13, (0) baffle plates in EC-14, 15, and EC-16.]† A wire
brush may be used to remove any carbon accumula­tion that may have developed in the combustion cham­ber. Vacuum the loose soot and debris from the boiler.
Replace baffle plates.

6. Inspect the burner combustion head. Clean if neces­sary and make sure all the adjustments are correct.
(See burner data pages for the burner installed.)
Replace oil nozzle with new one and readjust elec­trodes. To insure proper burner operation ONLY THE
NOZZLES SPECIFIED IN THIS MANUAL OR ON
THE BURNER LABEL SHOULD BE USED FOR
REPLACEMENT.

† A flue brush (triangular shape) is supplied with boiler.

7. Protect all of the fireside surfaces by swabbing with
neutral mineral oil.

8. Close main cast iron burner door

(door on which
burner is mounted). Make sure that the entire seal
(fiberglass rope) is making good contact with the
boiler casting when replacing four 13 mm hex head
screws and tightening.

D.If boiler room is damp, provide ventilation.

CAUTION: ALWAYS KEEP THE OIL SUPPLY VALVE SHUT
OFF IF THE BURNER IS SHUT DOWN FOR AN EXTENDED
PERIOD OF TIME

II. PROVIDING PROTECTION FOR FREEZING

Anti-freeze is sometimes used in hydronic heating sys­tems to protect against freeze-up in the event of power
failure, or safety control shutdown when the building is
unoccupied. It should be recognized that unless the build­ing is kept above freezing temperature by some means,
the plumbing system is not protected.

PROPYLENE GLYCOL is used in the quick-freeze food
industry; it is practically non-toxic. Its use may be permitted
when indirect water heaters are used. When anti-freeze
must be used, inhibited propylene glycol is recommended.
Useful information on the characteristics, mixing propor­tions, etc. of glycol in heating systems is given in Technical
Topics No. 2A, available from the Slant/Fin website, go to
http://slantfin.com. Go to library, select current literature,
select boiler model. See related topics and select
antifreeze and hydronic systems. Consult glycol manufac­turers for sources of propylene glycol.

DO NOT USE ETHYLENE GLYCOL BECAUSE IT IS TOXIC.

III. OIL BURNER

All service to the oil burner, oil filter, oil strainer, etc.,
should be performed by a professionally trained service
person. Inspect and clean annually and following any
period of improper operation. Recheck and adjust settings
as specified for burner model and nozzle size. Set burner
air using test instruments to obtain recommended CO

2

and

draft without smoke. See the Burner Data page in this
manual that corresponds to the burner installed.

IV. GENERAL MAINTENANCE

These operations are recommended to be performed at
regular intervals:
A.BOILER HEATING SURFACES: clean off all coatings

found. Reseal covers.
B.BOILER CONTROLS: check settings, correct functioning.
C.PIPING: check piping and accessories for leaks.
D.STUB VENT and BREECHING: check for obstructions

and leaks.
E.COMBUSTION AIR TO BURNER: check for continued

POSITIVE supply of air as required. Air needs are great-

est in coldest weather. Refer to AIR SUPPLY,

page 3.
F. WATER SYSTEM: check

1. System to be full of water and pressure to remain
stable (between 12 psi and 25 psi).

2. Air-control system: noise and air binding in radiation
should not occur.

3. Water lines: slightest leaks should be corrected.

G.BOILER ROOM AIR SUPPLY: air vents should be open

and free of obstruction.
