BOILER LOCATION
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:
* Without tankless coil
B. The ntrepid boiler can be installed on both combustible and non-
combustible floors, but must NOT be installed on or above carpeting.
C. The ntrepid Boiler has full wet base sections which surround fire-
box for maximum heat absorption of burning fuel, and low floor
temperature.
D. f 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.
CAUT ON: NEVER BURN GARBAGE OR PAPER N THE UN T AND
NEVER LEAVE COMBUST BLE MATER AL AROUND T.
MINIMUM CLEARANCE
Provide accessibility clearance of 24" from surfaces requiring servicing (top
and front) and 18" on any side requiring passage. The boiler shall be
installed with the following M N MUM clearances from combustible materials:
BACK AND S DES- 6"
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.
VENTING REQUIREMENT
• The terminal shall not be closer than 3 feet above or 10 feet horizon-
tally 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.
• The terminal shall not be less than 7 ft above grade when located
adjacent to 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 ter-
minate 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.
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 recommenda
tions 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. Flex-
L and Field Controls are the two approved manufacturers for venting kits.
When installing the vent kits the manufacturers instructions must be fol-
lowed.

Notes: Jacket must be installed on boiler units prior to installation of trim.
. WATER BO LER TR M, see page 2 for tapping locations, and figures
1 and 2 for illustration of water boiler.
A. Pressure- temperature - Altitude gauge — use tapping no. 6.
B. High temperature limit — use tapping no. 7.
C. Operating control (if used) — use tapping no. 7.
D. Water relief valve — use tapping no. 3, piped full size to boiler.
E. Automatic air vent or compression tank tappings — if
used, install in tapping no. 2.
F. Combustion safety control — mounted on burner.
PIPING
IMPORTANT: Boilers are to be used with closed system. Any application
that uses steam or 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 UNIT
NOTE: On knock down boiler only, jacket may be installed after supply and
return piping connection, but must be installed prior to adding trim.
. C RCULAT NG SYSTEM
A. FORCED C RCULAT ON hot water heating system: Use the top
tapping as supply tapping, and use the front or rear bottom
tappings for the return.
B. A FLOW CONTROL VALVE (See figure 4) will prevent gravity
circulation and usually is required when tankless heater is installed.

. A R CONTROL SYSTEMS
A. D APHRAGM-TYPE COMPRESS ON TANKS are used to control
system pressure in an A R EL M NAT NG SYSTEM: an automatic
air vent is used to REMOVE air from the system water. See figure 4.
f 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.
B. CONVENT ONAL COMPRESS ON TANKS (non-diaphragm type)
are used to control system pressure in an A R COLLECT NG
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.
f 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 5)
C. HOT WATER RAD AT ON VENT NG - 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 LOCAT ON - Locating low-head pump(s) on return to boiler is
acceptable for smaller boiler sizes in residences of one or two stories.
(See figure 4) The pump location shown in figure 5 is required in large,
multi-story building installations, especially when high-head pumps
are used.
E. A conventional compression tank may be connected to the 3/4"
tapping as shown in figure 5.
IMPORTANT: Hot water heating systems containing high water volume, such
as would occur with cast iron radiation, require special care with air elimina-
tion. 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.
(See Figure 4, Alternate Pump Location.)
PIPING TANKLE HEATER (if used)
. Heater capacities are listed on page 2.
. Pipe the built-in tankless heater using the inlet and outlet tappings
indicated on the heater (figure 6).
A. Tempering valve (illustrated, but not furnished) is suggested to provide
more volume of temperate water to kitchen and bath.
B. High temperature water, for dishwasher and laundry, may be piped direct.
C. A flow control valve should be used to control the rate of flow of water
through the coil, otherwise the heating capacity of the coil will be
exceeded. To insure sufficient hot water, the flow rate through the coil
should be limited to a maximum shown for intermittent draw in the ratings
table on page 2.
IMPORTANT: Escape pipes or drain pipes from relief valves, blow-down
valves, and low-water cut-offs must be piped off to a safe place.
IN TALLING THE BURNER
See Burner Data, pages 8-11, and Burner Manual supplied with burner. f
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 8-11. Check to see
that nozzle and settings are as given in burner data tables, pages 8-11.

OIL UPPLY PIPING
nstall the oil tank or tanks and piping from tank to burner. Follow local
codes and practices, NFPA No. 31, NSTALLAT ON OF O L BURN NG
EQU PMENT 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. n 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 nec-
essary, especially at low fuel oil flow rates (small nozzle sizes), to pre-
vent nozzle plugging. See Slant/Fin publication on one-pipe and two-
pipe fuel oil systems.
WIRING THE BOILER
• The wiring diagrams for the burner and boiler may be found on
pages 6-7.
• 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.
PRECAUTION BEFORE TARTING OIL BURNER

See Figure 6 for test port location.
• Smoke reading should be a trace or less on the smoke paper. Adjust
the burner as necessary for proper operation.
CLEANING AND FILLING A NEW WATER BOILER
. BEFORE F LL NG WATER BO LER
A. Check burner to be certain it is ready for firing. DO NOT F RE
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.
. CLEAN NG WATER BO LER SYSTEM
A. Prepare a boil-out solution of sodi m hydroxide (caustic soda) or
tri-sodi m phosphate.
NOTE: Use caution in handling chemicals. Caustic soda is
harmful to skin, eyes and clothing.
1. Proportions: 1 lb. of either chemical per 50 gallons of sys-
tem water.
2. Stir chemical in water until dissolved and pour into the boiler
through a top tapping. Replace plug.
B. Fill the entire system with water.
C. Start the burner, using the start-up procedure.
D. Circulate the water through the entire system.
E. Vent the system, including the radiation.
F. Allow boiler water to reach operating temperature, if possible.
G. Continue to circulate the water for a few hours.
H. Shut off the burner.
. With CAUT ON, drain the boiler solution to a safe location. DO
NOT LEAVE SOLUT ON S TT NG N SYSTEM OVER 2
HOURS.
J. Wash the water side of the boiler thoroughly using a high pres-
sure water stream. Fill and drain the boiler several times.
. TREAT NG WATER FOR CORROS ON CONTROL
(This is not scale control)
A. Prepare a solution of sodi m chromate.
Proportions: 6 oz. per 50 gallons of system water.
B. Stir chemical into water until dissolved and pour into the boiler
through a top tapping. Replace plug.
V. F LL NG AND VENT NG THE WATER BO LER
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. f brand-name air-control devices are used, venting instructions
furnished with the devices should be followed.
V. 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 tempera-
ture is reached, the high limit switch should open, and the burner
should shut off automatically. f the high limit does not operate to
shut off the burner, the high limit or the wiring is faulty. Repair or
replace immediately.
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 base-
ment or other boiler area. The homeowner should be made familiar with
operating the toggle to provide or stop the power to the boiler.

FIRING HEAD ADJU TMENT
By turning the head adjustment screw clockwise, the
burner head will move inside the blast tube AWAY from
the end cone. This achieves lower firing rates. Similarly,
by turning the head adjustment screw co nter-clock-
wise, the burner head will move inside the blast tube
toward the end cone, increasing the firing rate.
AIR HUTTER ADJU TMENT
Air adjustment is set at the factory. By turning the air
adjustment screw clockwise, the air shutter opening
increases. To achieve proper combustion, the air shutter
may need to be adjusted.

I. EXTENDED HUTDOWN, CLEANING OR REMOVAL OF BOILER
FROM ERVICE.
DANGER: Use CAUT ON when handling chemicals and draining hot
water from a boiler. Scalding water and/or chemicals can cause per-
manent 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 SW TCH 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. To clean the fireside boiler surfaces, first shut down burner by dis-
connecting all electrical power to the burner by turning OFF the
O L BURNER EMERGENCY SW TCH 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. nspect the entire vent connector back to the chimney and
clean if necessary.
3. nspect the chimney for soot, debris and other unsafe condi-
tions of the chimney and take the necessary action.
4. Remove the flue collector by first removing the top jacket
panel. The flue collector is held in place by two hex 1/4-20
screws. Remove the screws and carefully remove the flue col-
lector. Try not to disturb the flat fiberglass rope under the flue
collector.
5. When necessary to clean the combustion chamber you must
first CLOSE the suction valve (and return valve if two pipe).
Then disconnect the oil lines from the burner. 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 direc-
tion of the conduit until it is disconnected. Remove the single
3/8-16 hex head screw on the LEFT side of the swinging door.
You will need a 9/16” drive socket. Open the door to complete-
ly expose the combustion chamber for thorough cleaning and
for inspection of target wall, blanket (provided in certain mod-
els; see rating plate), main cast iron burner door insulation
and burner door fiberglass sealing rope. f combustion cham-
ber parts above are badly deteriorated then replace with origi-
nal factory parts available at your distributor.
6. Use the flue brush to clean the pinned flueways between the
sections.† 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.
7. nspect 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 opera-
tion ONLY THE NOZZLES SPEC F ED N TH S MANUAL OR
ON THE BURNER LABEL SHOULD BE USED FOR
REPLACEMENT.
8. Protect all of the fireside surfaces by swabbing with neutral
mineral oil.
9. 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
3/8-16 x 1” long hex head bolt and tightening.
10. Check the flue collector seal. This is the flat rope seal on top
of the heat exchanger. The rope must be in place adjacent to
the long bosses on front and rear sections and adjacent to the
short bosses on the intermediate sections. The rope should
be directly under the flue collector flanges when the flue col-
lector is replaced. Use the two 1/4-20 x 3/4” washer hex head
screws to fasten the flue collector. n order to assure a proper
seal be sure that the flue collector is compressing the flat rope
and not hanging up on the section bosses. Tighten the two
screws.
C. f boiler room is damp, provide ventilation.
CAUTION: ALWAYS KEEP THE O L SUPPLY VALVE SHUT OFF F
THE BURNER S SHUT DOWN FOR AN EXTENDED PER OD OF
T ME.
II. PROVIDING PROTECTION FOR FREEZING
Anti-freeze is sometimes used in hydronic heating systems to pro-
tect against freeze-up in the event of power failure, or safety control
shutdown when the building is unoccupied. t 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. ts use may be permitted when tankless 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 Hydronics nstitute, 35 Russo
Place, Berkeley Heights, N.J. 07922. 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 strainers, etc., should be
performed by a professionally trained service person.
nspect 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 and draft regulator, using test instru-
ments to obtain recommended CO2and draft without smoke.
Refer to page 5.
IV. GENERAL MAINTENANCE
These operations are recommended to be performed at regular
intervals:
A. BO LER HEAT NG SURFACES: clean off all coatings found.
Reseal covers.
B. BO LER CONTROLS: check contacts, settings, correct
functioning.
C. P P NG: check piping and accessories for leaks.
D. CH MNEY or STUB VENT and BREECH NG: check for obstruc-
tions and leaks.
E. COMBUST ON A R TO BURNER: check for continued POS T VE
supply of air as required. Air needs are greatest in coldest
weather. Refer to A R 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.
4. Low water cut-off, for operation (see instructions furnished
with unit). See page 9.
G.BO LER ROOM A R SUPPLY: air vents terminal should be open
and free of obstruction. See page 3.
† A flue brush (2-1/4" dia.) is supplied with boiler. Replacements
are available from dealer or hardware stores.
