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 13 and 17 of this manual are used, and
are properly adjusted to produce 13% CO2.
§ Boiler models have two firing rates. The boiler is factory shipped at the lower
firing rate. To obtain the higher firing rate, refer to the boiler installation
instructions for the appropriate field adjustments.
# All dimensions subject to normal manufacturing tolerance.
NOTE: All boilers under 300,000 Btuh (87.9 kw) input are tested and rated for
capacity under the U.S. Department of Energy (D.O.E.) Test Procedures for
Boilers.

THE INSTALLATION INSTRUCTIONS IN THIS MANUAL
ARE ABBREVIATED. SEE THE FRONT COVER OF THIS
MANUAL FOR REFERENCES TO CODES AND STANDARDS.
BOILER LOCATION
CAUTION: NEVER BURN GARBAGE OR PAPER IN THE
UNIT, AND NEVER LEAVE COMBUSTIBLE MATERIAL
AROUND IT.
Provide a level, solid foundation for the boiler. Location should
be near the chimney so that the Flue Pipe Connector or
Breeching to the chimney is short and direct.
A. The foundation must be capable of supporting the weight
of the boiler when filled with water:
* Includes burner, circulator and controls
B. The EC-10 Boiler has full wet base sections which sur-
round 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:
A. CHIMNEY CONNECTOR-18"
B. BACK- 6" EXCEPT as limited by 18" clearance from chim-
ney connector
C. SIDES- 2" EXCEPT as limited by 18" clearance from chim-
ney connector
NOTE: Except in closets and alcoves, clearances above in (A)
and (B) may be reduced by providing forms of protection as
specified in NFPA 31, latest edition.
See bottom of page 4 for clearance diagrams.
CHIMNEY REQUIREMENTS (see NFPA 211, latest edition)
A. The chimney must be constructed in accordance with all
local applicable codes and the National Board of Fire
Underwriters. See boiler models and rating table shown on
page 2 for chimney sizes.
B. Check chimney condition.
Existing chimneys and stacks may have deteriorated; without repairs their use would be hazardous. Before connecting to an old chimney or stack:
1. Clean it.
2. Inspect it thoroughly.
3. Remove obstructions.
4. Replace worn sections of metal stacks.
5. Seal bad masonry joints.
6. Repair damaged lining.
C. Breeching area must not be reduced at connection into
chimney. Breeching must be inserted into, but not beyond,
inside of chimney liner.
D. Chimney height shall extend at least 3 feet above where it
passes through the roof of the building, and at least 2 feet
above any ridge within 10 feet of the chimney.
E. The use of a vent cap, where permitted by code, gives
additional protection against adverse wind conditions and
precipitation.
F. Flue Connection: Connect flue pipe between top of boiler
and chimney. Horizontal sections of flue pipe must be
pitched upward to the chimney at least 1/4" per foot. Flue
must be inserted into, but not extend beyond, the inside
wall of the chimney flue. Draft regulator is not required but
may be installed if conditions warrant it. Install draft regulator in flue pipe, as shown in figure 2.
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.
AIR SUPPLY AND VENTILATION (see NFPA 31, latest edition)
Sufficient air for combustion and ventilation in the boiler room
must be provided. Failure to do this will result in poor combustion, heavy sooting and health hazards. Any oil-fired boiler
must have a steady draft* and an ample supply of combustion
air at all times during firing. If air supply or chimney draft* is

unreliable, CO2and overfire draft* will change unpredictably.
DO NOT vent this boiler to the same chimney flue used by a
fireplace or coal or wood burning furnace or boiler. The draft*
produced by solid fueled devices varies tremendously
between high fire and low fire:
In modern, weather stripped, energy-saving buildings or older
buildings which have been modified similarly, natural infiltration may not supply enough air for combustion, particularly if
other fuel burning appliances, exhaust fans or draft inducers
are competing for the same air supply. Fireplaces, other solid
fuel burning appliances and exhaust fans consume great
quantities of air; if air supply is not ample, such an appliance
will create a downdraft in the oil-fired boiler flue. This can create a hazardous condition. Flue gases can be sucked out of
the chimney through the vent regulator into the living space.
DO NOT operate this boiler and a solid fuel burning appliance
at the same time, unless the solid fuel burner is provided with
its own outside air supply.
See Table 2, “Provisions for Combustion and Ventilation Air
Supply” for determining need and method of providing air for
combustion and ventilation.
If fly screen must be used over air supply openings, areas calculated should be doubled; the screen should be inspected
and cleaned frequently to maintain free air flow.
Protect air openings against closure by snow, debris, etc.
Openings such as doors or windows, if used, must be locked
open.
TABLE 2: Provisions for Combustion and Ventilation Air Supply. See NFPA 31, latest edition for more detailed information.
Boiler Location Air Supply
2.1 Unconfined space Is there sufficient air for combustion by natural infiltration (see
NOTE (1), “Test...” below)?
2.2 Unconfined space If there is NOT sufficient air for
combustion by natural infiltration
due to tight construction or other
conditions, then it REQUIRES AIR
FROM OUTDOORS. SEE
“ACTION REQUIRED” column at
right. See Notes (1) and (2) below.
2.3 Confined space If there is sufficient air for combustion from within building but it
comes from outside of the
confined space, see “ACTION
REQUIRED” column at right.
See Note (1) below.
2.4 Confined space If there is NOT sufficient air for
combustion due to tight construction or other conditions it
REQUIRES AIR FROM OUTDOORS. SEE “ACTION
REQUIRED” column at right.
See NOTE (2) below.
Action Required
NONE
Provide air from outdoors directly through a permanent outside wall opening or openings with a free open area of not
less than 1 sq. in. per 4000 Btu/hr of TOTAL input of ALL fuel
burning appliances in the building. See Note (1) and (3).
The confined space shall be provided with two permanent air
openings, one near the top of the enclosure and one near the
bottom. EACH opening shall have a free air opening of not
less than 1 sq. in. per 1000 Btu/hr. of TOTAL input of ALL fuel
burning appliances within the enclosure. The two openings
shall freely communicate with the interior areas of the building
which in turn would have to have adequate infiltration of air
from outdoors. See Notes (1, 3) and Figure 3a.
(a) Air from the outdoors shall be provided to the confined
space by two permanent openings, one in or near the top
of the enclosure space and one in or near the bottom. The
openings shall communicate directly, or by means of
ducts, with outdoors or to such spaces (crawl or attic) that
freely communicate with outdoors (See figures 3b, 3c
and 3d).
(b) Where directly communicating with outdoors or by means
of vertical ducts, each opening shall have a free area of
not less than 1 sq. in. per 4,000 Btu/hr. (35 sq. in. per gal.
per hr.) of total input rating of all appliances in the enclosure. If horizontal ducts are used, each opening shall have
a free area of not less than 1 sq. in. per 2,000 Btu/hr. (70
sq. in. per gal. per hr.) of total input of all appliances in the
confined space. See Figures 3b, 3c and 3d.
(1) Test for sufficient air for combustion by infiltration by running this boiler for 30 minutes under all of the following conditions and at the same time: a) all doors, win-
dows and other like openings must be closed, b) all fuel burning appliances should be FIRING, c) all exhaust fans and clothes dryers turned ON. At the above
conditions the CO2, smoke and draft readings must be normal. (CO2between 11% and 13%, smoke between ZERO and a TRACE, draft between .02” W.C. and
.04” W.C. negative pressure in the breeching.)
(2) Aside from tight construction, some of the conditions that steal air for combustion from a boiler are other fuel burning appliances, exhaust fans and clothes dryers.
(3) Generally, louvers made of wood have a free open area of 20% and those made of metal have a 60% to 70% free open area. Screens also reduce the open area
of the louvers. Fly screen can reduce air opening by 50%.
* Draft is negative or suction pressure

INSTALLING CONTROLS AND ACCESSORIES
ON BOILER UNITS
Notes:Jacket must be installed on boiler units prior to
installation of trim.
WATER BOILER TRIM, see page 2, figures 1 and 2 for tapping locations.
WATER PIPING FOR HOT WATER HEATING BOILERS
NOTE: On knocked-down boiler only, jacket may be installed
after return piping connection, but must be installed prior to
adding trim, supply piping and drain valve.
I. CIRCULATING SYSTEM
A. FORCED CIRCULATION hot water heating system: Use
the top tapping as supply tapping, and use the rear bottom tapping for the return.
B. A FLOW CONTROL VALVE will prevent gravity circula-
tion and is required when an external tankless heater,
an indirect water heater or multiple circulators are
installed.
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 4)
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 4 and at radiation high points.
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 except at radiation high points.
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.
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 only acceptable in residences of one
or two stories. The pump location shown in figure 4 is
required in large, multi-story building installations, especially when high-head pumps are used and is also rec-
ommended for all applications.
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. For alternate circulator pump location on
return for low-head pumps and one or two story buildings ONLY.
DOMESTIC HOT WATER
For Indirect-fired storage water heater application, see
Slant/Fin publication WH-10, Sizing Guide WH-SG and
Installation manual WH-40. The installation manual includes
several control systems and relay centers for space and
domestic water heating in addition to plumbing.
INSTALLING THE BURNER
See Burner Data, pages 13-17, 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 on pages 13-17. Check to see
that nozzle and settings are as given in burner data tables,
pages 13-17.
CAUTION: Do Not use gasoline, crankcase drainings, or any
oil containing gasoline.

OIL SUPPLY PIPING
Install the oil tank or tanks and piping from tank to burner.
Follow local codes and practices, INSTALLATION OF OIL
BURNING EQUIPMENT, NFPA 31, latest edition, 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 feet. Where the total
lift is greater than 8 feet, 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. Fuel oil shutoff
valves should be installed at the burner on the supply (and
return if two-pipe) to facilitate servicing. See Slant/Fin publication on one-pipe and two-pipe fuel oil systems.
WIRING THE BOILER
(see National Electric Code ANSI/NFPA 70-latest edition)
A. The wiring diagrams for the burner and boiler may be found
on pages 11 through 15.
B. 24 volt control wiring should be approved Safety Circuit
wire, protected as needed.
C. Power supply wiring to the burner must be 14 gauge, as
required, and should have a properly fused disconnect switch.
120 volt wiring to pumps and safety controls must also be 14
gauge. Wire must be enclosed in approved conduit.
D. The wires supplying power to the burner MUST go through
the quick disconnect plugs provided with the boiler.
E. 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.
VENT PIPING AND DRAFT REGULATOR
(see NFPA 31, latest edition)
A. Vent connectors must be the same diameter as the boiler
flue collar. (See page 2)
B. Vent pipes and breeching must be pitched upward a mini-
mum of 1/4" per foot.
C. Connect vent pipe to the chimney using as few elbows as
possible and as short as possible within NFPA 31 or
authority.
D. Horizontal vent connector into the chimney should not be
inserted beyond the inside wall of the chimney.
E. Install barometric draft regulator on horizontal breeching,
near chimney, with hinge horizontal and face vertical condi-
tions permitting as in Figure 3a. See Figure 3b as a second
choice. See manufacturer's instructions packed in carton
with barometric draft regulator.
F. If two or more appliances are used on the same chimney,
see CHIMNEY, page 3.
G. Make up all joints with minimum air leaks, secure with
sheet metal screws.
PRECAUTIONS BEFORE STARTING OIL BURNER
Make a positive check of A through F before starting burner:
A. Boiler and system are full of water. All air is vented from
system. See below.
B. All wiring is completed. See page 11 through 15.
C. Oil supply is connected to the burner; nozzle is installed
correctly; oil valve is open at tank.
D. Main cast iron door on which burner is mounted is bolted
shut and fiberglass rope seal is making good contact.
E. Smokepipe is connected to chimney.
F. All combustible materials are cleared away.
G. Combustion air supply is provided. See page 3.
H. Burner settings are adjusted as per pages 8, 9, 17-21 and
as shown on boiler jacket.
START-UP (COMBUSTION TEST INSTRUMENTS MUST
BE USED) THIS BOILER IS A POSITIVE PRESSURE BOILER.
A. Make sure the boiler is installed and wired properly and is full
of water.
B. The observation port cover is mounted on the hinged burner
mounting door (see figure 2 on page 2). NEVER touch the
port cover or any surrounding surfaces with hands. They may
be HOT. Use tools. Loosen the 2 screws and swing cover
until window is directly below pivot (and tighten 2 screws) to
observe through window. Loosen the 2 screws and swing
cover until slot is directly below pivot (and tighten 2 screws)
to be able to insert probe through slot. See the burner
instructions for bleeding air, etc. Step away from the boiler
and start the oil burner.
C. IMMEDIATELY, set burner air bands to obtain a bright fire
without smoke or oil stain. Set the DRAFT REGULATOR to
obtain .02" – .04" draft at the breeching.
D. Tighten the observation door screw. Allow the burner to fire
for at least one hour total firing time, to bake out the volatile
binders in the combustion chamber before taking final com-
bustion readings.
E. By alternate adjustment of the barometric draft regulator, the
burner air regulation and head regulation devices (whichever
apply), set for a zero to a trace of smoke and 12% CO
2
.
Then open the air bands or shutter (whichever apply) an
additional 1/8". This should result in zero smoke with NO raw
oil on the smoke paper and a smooth light-off. DO NOT
ATTEMPT TO SET FIRE BY EYE. Flame retention burners
may appear efficient and smoke free from an inefficient 7%
up to an overly high 14% CO
2
. However, a very low CO2can
also result in poor ignition and raw (unburned) oil entering the
fire box. At very high CO
2
, any slight decrease in air flow for
any reason will cause incomplete combustion, with high
smoke and dry soot formation in the fire box.
F. Once burner and draft have been set up, then smoke, CO
2
and stack temperature should be checked and recorded. If
smoke is greater than trace, review the burner instructions
and replace the nozzle if necessary. Normal smoke to be
expected is zero to a trace.
G. Make sure that the observation port cover is closed and
the screw is tightened.
CLEANING AND FILLING A NEW WATER BOILER
I. There are a number of commercial preparations available
from your distributor for cleaning and for corrosion protection
conditioning the internal (waterside) surfaces of boilers.
Follow the preparation manufacturer’s instructions.
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.
