1. Ventilation of boiler room must be adequate enough to
provide sufficient air to properly support combustion.
2. When boiler is located in an unconfined space in a
building of conventional construction frame, masonry
or metal, infiltration normally is adequate to provide
air for combustion and ventilation. However, in any
building which has been altered to conserve energy
or to minimize infiltration, the boiler area should be
considered as a CONFINED SPACE. Provide combustion
air and ventilation air in accordance with the section
“Air for Combustion and Ventilation,” of NFPA 31:
Standard for the Installation of Oil-Burning Equipment.

* Unconfined area: A space whose volume is not less than 50 cubic feet per 1000 Btu per hour of all
appliances installed in that space (cubic feet of space = height x width x length).
** Confined area: A space whose volume is less than 50 cubic feet per 1000 Btu per hour of all appliances
installed in that space (cubic feet of space = height x width x length).
3. When a boiler is installed in an unconfined space,
in a building of unusually tight construction, air for
combustion and room ventilation must be obtained
from outdoors or from spaces freely communicating
with the outdoors. A permanent opening or openings
having a total free area of not less than 1 square
inch per 5,000 Btu per hour of total input rating of all
appliances shall be provided. Ducts may be used to
convey make-up air from the outdoors and shall have
the same cross-sectional area of the openings to which
they are connected.

4. When air for combustion and room ventilation is from
inside buildings, confined space shall be provided with
two permanent openings, one starting 12 inches from
the top and one 12 inches from the bottom of the
enclosed space. Each opening shall have a minimum
free area of 1 square inch per one thousand (1,000)
Btu per hour of the total input rating of all appliances
in the enclosed space, but must not be less than one
hundred (100) square inches. These openings must
freely communicate with the interior areas having
adequate infiltration from the outside. See Figure #1.
5. When the boiler is installed in a confined space and
all air is provided from the outdoors, the confined
space shall be provided with two permanent openings,
one commencing within 12 inches from the top and
one commencing 12 inches from the bottom of the
enclosure. The openings shall communicate directly, or
by ducts, with the outdoors or spaces (crawl or attic)
that freely communicate with the outdoors. One of the
following methods must be used to provide adequate
air for ventilation and combustion.
A. When directly communicating with the outdoors,
each opening shall have a minimum free area
of 1 square inch per 4,000 Btu per hour of total
input rating of all equipment in the enclosure. See
Figure #2.

B. When communicating with the outdoors by means
of vertical ducts, each opening shall have a
minimum free area 1 square inch per 4,000 Btu per
hour of total input rating of all appliances in the
enclosed space. See Figure #3.
C. If horizontal ducts are used, each opening shall
have a minimum free area 1 square inch per 2,000
Btu per hour total input rating of all appliances in
the enclosed space. See Figure #4.
D. When ducts are used, they shall be of the same
cross sectional area as the free area of the area of
the openings to which they connect. The minimum
dimension of rectangular air ducts shall not be less
than 3 inches.
6. In calculating free area using louvers, grills or screens
for the above, consideration shall be given to their
blocking effect. Screens used shall not be smaller than
¼ inch mesh. If the free area through a design of
louver or grill is known, it should be used in calculating
the size opening required to provide the free area
specified. If the design and free area is not known,
it may be assumed that wood louvers will have 20-
25% free area and metal louvers and grills will have
60-75% free area. Louvers and grills shall be fixed in
the open position or interlocked with the boiler so that
they are opened automatically during boiler operation.

INSPECT CHIMNEY to make certain it is constructed
according to latest revision of the NFPA 211. Local codes
may differ from this code and should be checked. Where
there is a conflict, local code will prevail.
• Boiler must be installed into chimney which has
masonry or metallic chimney liner.
• Unlined chimney will have leaks that will cause poor
chimney performance (NO DRAFT), and could result in
poor positive pressure in combustion chamber.
• Horizontal portions of venting system should not
exceed 10 feet in length. Horizontal lengths over 10
feet will have negative effect on chimney performance.
• Chimney should extend at least 2 feet above any
portion of building within 10 feet. See Figure #15. It
should produce negative draft of .06 to .08 inches of
water column, (W.C.), as measured with draft gauge
between boiler and barometric draft control while
maintaining .02 inch W.C. negative draft in combustion
chamber. See chart “Chimney or Vent Sizes” for
recommended chimney or vent sizes.
• Inadequate draft will cause improper combustion,
resulting in dirty flue ways and high fuel bills.
CONNECT FLUE PIPE same size as boiler outlet to
chimney, sloping upward continuously toward chimney
approximately ¼” per foot. Bolt or screw joints together to
avoid sag.
If oil fired water heater is vented into same flue as
boiler, provide separate hole into chimney whenever
possible. When not possible, use “Y” connection in
flue pipe, using separate draft regulator for each unit.
When chimney will not provide adequate draft
to handle input from water heater and boiler
simultaneously, wire units so that only one will
operate at a time, favoring water heater.

• Install burner per instructions provided with burner-in-
a-box kit.
• Install oil tank and piping in accordance with the
National Board of Fire Underwriters and local
regulations.
• Oil storage tank, vent, fill pipe and caps should be as
prescribed by local codes.
• In no case should vent pipe be smaller than 1¼” I.P.S.
Fill pipe should not be less than 2” I.P.S.
• Suction line from tank to burner should be one
continuous piece of tubing to prevent air entering line.
• Suction line, must be ⅜” O.D. copper tubing for runs of
50 feet or less, and ½” O.D. for longer runs. Oil return
line, same size as suction line, must be used on any
installation where bottom of tank is below fuel unit of
burner.
• Oil lines should be buried or otherwise protected from
mechanical injury.
• Flare fittings on all oil lines are recommended.
Compression fittings on suction line often allow air to
be drawn into fuel pump, making it difficult to maintain
oil pressure at nozzle.
• Do not run overhead fuel lines from tank to oil burner.
• Fuel pump connections and by-pass should be made
according to instructions attached to fuel pump. If
tank is more than 20’ from boiler, a two stage fuel
unit should be installed in place of single stage pump
supplied as standard equipment with burner. Make
certain rotation and speed are same and pump is
suitable for burner horsepower rating.
• Oil line filter and shut-off valve should be installed in
suction line. Shut-off valves should be installed in both
suction and return lines at burner for convenience in
servicing burner.
• Allow extra tubing at burner so burner may be removed
from boiler for cleaning without disconnecting tubing.
(See Figures #16 & #17, below).
• Optional flexible oil line is available.

Thermostat Installation
1. Thermostat should be installed on inside wall about
four feet above the floor.
2. NEVER install thermostat on outside wall.
3. Do not install thermostat where it will be affected by:
• Drafts
• Hot or cold pipes
• Sun light
• Lighting fixtures
• Television sets
• Fireplace or chimney
4. Check thermostat operation by raising and lowering
thermostat as required to start and stop burner.
5. Instructions for final adjustment of thermostat
are packaged with thermostat ( adjusting heating
anticipator, calibration, ect.).
Electrically bond boiler to ground in accordance with
requirements of authority having jurisdiction. Refer to:
• USA- National Electrical Code, ANSI/NFPA 70.
Install fused disconnect switch between boiler and meter at
convenient location.
Sequence Of Operations
On call for heat, thermostat will actuate, completing
circuit to limit. In turn, circulator and ignition systems are
activated and ignition will begin.
In event boiler water temperature exceeds high limit
setting on boiler mounted limit, power will be interrupted
between limit and ignition system. Power will remain off
until boiler water temperature drops below high limit
setting. Circulator will continue to operate under this
condition until thermostat is satisfied.
ELECTRICAL WIRING
WARNING
Electrical shock hazard. Turn OFF electrical power supply
at service panel before making electrical connections.
Failure to do so could result in death or serious injury.

Operating Instructions
1. Inspect venting system at start of each heating season.
2. Check vent pipe from boiler to chimney for signs
of deterioration by rust or sagging joints. Repair if
necessary.
3. Remove vent pipe at base of chimney or flue and, using
mirror, check for obstruction.
Safety Relief Valve
WARNING
Burn and scald hazard. Safety relief valve could
discharge steam or hot water during operation.
!
• Operate lever of safety relief valve, on boiler
periodically to make sure it is functioning properly.
• Safety relief valve should open before water pressure
exceeds 30 psi. reading on gauge. If this pressure is
exceeded and safety relief valve leaks water when
boiler is operating at normal pressures, it should be
immediately replaced.
• Corrosion can build up rapidly at valve seat and
prevent its functioning as safety device. See Figure
#11, page 13.
Start-Up And Adjustment Of Oil Burner
(See oil burner instructions for nozzle and electrode
setting)
A. Check oil burner nozzle to make certain it is tight in
adapter. Burner mounting bolts should be tight.
B. Check electrode setting, they may have been jarred
out of position during transportation.
C. Lubricate burner motor and circulator motor if
required. Some circulators are water lubricated and
do not require oiling.
D. Set room thermostat to call for heat, or jump
thermostat contacts on the boiler control.
E. Open all oil line valves.
F. Turn service switch on. Burner should start.
G. On one pipe fuel systems only, vent pump as soon
as burner starts. Allow oil to run until all traces of
air in the suction line disappear.
H. Turn “OFF” burner and install pressure gauge port
on pump.
I. Start burner again and check oil pressure for 140
psi.. Adjust if necessary.
Do not set fire visually.
Instruments are only reliable
method to determine proper air adjustments.
Improperly adjusted burner causes soot and high fuel bills
because of incomplete combustion of fuel oil. This in turn
may require excessive boiler maintenance, service costs,
and in some instances, house cleaning or redecorating. A
competent service mechanic should be consulted to make
proper adjustments with smoke tester, CO2indicator and
draft gauge. Bacharach or Dwyer test kits include these
instruments.
Instructions For Proper Operation Of Boiler
Burner Unit
A ¼” diameter slot is provided in inspection cover plate to
take draft readings in combustion chamber. See Figure
#20. A ¼” diameter hole will be required in flue pipe
between boiler and barometric damper (if used) to take
draft, CO2, smoke and temperature readings. Adjust air
shutter on oil burner to obtain “trace” of smoke. Measure
CO2at this point. Increase air adjustment to lower CO2
approximately one (1) percent. Check to insure minimum
negative .02 w.c., (water column), “overfire” draft and
zero (0) smoke. If - .02 w.c. “overfire” draft can not be
maintained, changes and/or modifications may be required
in venting or chimney.
Following table (page 21) is provided as guideline for
initial start-up. Final adjustments MUST be made using
combustion instruments as previously mentioned.
Check Safety Control Circuit - after burner adjustments
have been made for satisfactory performance.
1. High limit control: remove cover and note temperature
setting. See Figure #20. With burner operating,
decrease setting to minimum point. When boiler water
temperature exceeds this set point, high limit switch
will open, shutting off power to oil burner. Return
setting to desired high limit point. Burner should
restart. Refer to instructions included with limit.
2. Primary control and flame sensor check following:
A. Flame failure - simulate by shutting off oil supply
with hand valve while burner is on. Sixty seconds
after flameout, the safety switch locks out, ignition
stops, motor stops and oil valve - when used -
closes. To restart, open oil supply valve and reset
safety switch.
B. Ignition failure - with burner off, close oil supply
valve and run through start-up procedure, The
safety switch should lock out as in flame failure.
