1. When a boiler is located in an unconned
space in a building of conventional
construction frame, masonry or metal,
inltration normally is adequate to
provide air for combustion and ventilation.
However, in any building which has
been altered to conserve energy or to
minimize inltration, the boiler area
should be considered as a CONFINED
SPACE. If there is any doubt, install air
supply provisions for combustion and
ventilation in accordance with section 5.3,
Air for Combustion and Ventilation, of the
latest revision of the NFPA 54 code, the
recommendations that follow, or applicable
provisions of the local building codes.

* Unconned area: A space whose volume is not less than 50 cubic feet per 1000 BTU per hour of all appli-
ances installed in that space (cubic feet of space = height x width x length).
** Conned area: A space whose volume is less than 50 cubic feet per 1000 BTU per hour of all appliances in-
stalled in that space (cubic feet of space = height x width x length).
2. When a boiler is installed in an unconned
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.

!
WARNING
Air openings to combustion area must not be
obstructed. Follow the chart below to obtain
and maintain adequate combustion air.

3. When air for combustion and room ventilation is
from inside buildings, the conned 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 inltration from the outside. See
Figure #4.
4. When the boiler is installed in a conned space
and all air is provided from the outdoors, the
conned 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 #3.

INSPECT CHIMNEY to make certain it is constructed
according to the latest revision of NFPA211. Local codes
may differ from this code and should be checked. Where
there is a conict, the local code will prevail.
This boiler must be installed into a chimney which has
a masonry or metallic chimney liner.

WARNING
Boiler is to be vented by natural draft and
shall not be connected into any portion of a
mechanical draft system operating under a
positive pressure.
Figure 5

11
An unlined chimney will have leaks that will cause
poor chimney performance (NO DRAFT), and could
result in poor positive pressure in the combustion
chamber.
Horizontal portions of the venting system should not
exceed 10 feet in length. Horizontal lengths over
10 feet will have a negative effect on the chimney
performance.
The chimney should extend at least 2 feet above any
portion of the building within 10 feet. See gure 5 at
right. It should produce a negative draft of .06 to .08
inches of water column, (W.C.), as measured with a
draft gauge between the boiler and barometric draft
control while maintaining an .02 inch W.C. negative
draft in the combustion chamber. See chart below for
recommended chimney or vent sizes.
Inadequate draft will cause improper combustion,
resulting in dirty ue ways and high fuel bills.
When installing a single boiler, connect the ue
pipe with the same size as the boiler outlet to the
chimney, sloping upward continuously toward the
chimney approximately ¼” per foot. Bolt or screw
joints together to avoid sag.
If an oil red water heater is vented into the same
ue as the boiler, provide a separate hole into
the chimney whenever possible. When this isn’t
possible, use a “Y” connection in the ue pipe,
using a separate draft regulator for each unit.
When a chimney will not provide adequate draft to
handle the input from the water heater and boiler
simultaneously, wire the units so that only one will
operate at a time, favoring the water heater.

Oil tank and piping should be installed in accordance
with the National Board of Fire Underwriters and local
regulations. Oil storage tank, vent, ll pipe and caps
should be as prescribed by local codes. In no case
should the vent pipe be smaller than 1 ¼” I.P.S. The
ll pipe should not be less than 2” I.P.S.
The suction line from the tank to the burner should
be one continuous piece of tubing to prevent air
entering the line. The suction line, must be ⅜” O.D.
copper tubing for runs of 50 feet or less, and ½”
O.D. for longer runs. An oil return line, same size
as the suction line, must be used on any installation
where the bottom of the tank is below the fuel unit
of the burner. Oil lines should be buried or otherwise
protected from mechanical injury. Flare ttings on all
oil lines are recommended. Compression ttings on
the suction line often allow air to be drawn into the
fuel pump, making it difcult to maintain oil pressure
at the 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 the
fuel pump. If tank is more than 20’ from the
boiler, a two stage fuel unit should be installed
in place of the single stage pump supplied as
standard equipment with the burner. Make certain
the rotation and speed are the same and the
pump is suitable for the burner horsepower rating.
An oil line lter and shut-off valve should be
installed in the suction line. Shut-off valves
should be installed in both the suction and return
lines at the 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 #7 & #8). An
optional exible oil line is available.

The venting system should be inspected at the start
of each heating season. Check the vent pipe from
the boiler to the chimney for signs of deterioration by
rust or sagging joints. Repair if necessary.
Remove the vent pipe at the base of the chimney or
ue and, using a mirror, check for obstruction.
The lever of the pressure relief valve, shown in
Figure #9, on the boiler should be operated
periodically to make sure that it is functioning
properly. The pressure relief valve should open before
the water pressure exceeds the 30 lb. reading on the
gauge. If this pressure is exceeded and the pressure
relief valve leaks water when the boiler is operating
at normal pressures, it should be immediately
replaced. Corrosion can build up rapidly at the valve
seat and prevent its functioning as a safety device.
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, as 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
lbs. Adjust if necessary.
Instruments are the only reliable method to
determine proper air adjustments. An improperly
adjusted burner causes soot and high fuel bills
because of incomplete combustion of the 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 the proper adjustments
with a smoke tester, CO2indicator and draft
gauge. Bacharach or Dwyer test kits include these
instruments.
INSTRUCTIONS FOR PROPER OPERATION
OF THE BOILER-BURNER UNIT
A ¼” diameter slot is provided in the inspection
cover plate to take draft readings in the combustion
chamber. See Figure #9. A ¼” diameter hole will
be required in the ue pipe between the boiler
and barometric damper (if used) to take draft,
CO2, smoke and temperature readings. Adjust air
shutter on oil burner to obtain a “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),
“overre” draft and zero (0) smoke. If - .02 w.c.
“overre” draft can not be maintained, changes and/
or modications may be required in the venting or
the chimney.
The following table (on next page) is provided as a
guideline for initial start-up. Final adjustments MUST
be made using combustion instruments as previously
mentioned.
OPERATING INSTRUCTIONS
!
CAUTION
Do not set re visually.
!
CAUTION
Water will be boiling hot.

15
CHECK SAFETY CONTROL CIRCUIT after
burner adjustments have been made for satisfactory
performance.
A. High limit control: remove cover and note
temperature setting. See Figure #13. With
the burner operating, decrease this setting
to the minimum point. When boiler water
temperature exceeds this set point, the high
limit switch will open, shutting off the power to
the oil burner. Return setting to desired high
limit point. Burner should restart.
B. Primary control and ame sensor:
Check:
1. Flame failure - simulate by shutting off oil supply
with hand valve while burner is on. Sixty seconds
after ameout, 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.
2. Ignition failure - with burner off, close oil supply
valve and run through start-up procedure, The
safety switch should lock out as in ame failure.
3. Power failure - Turn off main power supply switch
while burner is operating. When burner stops,
restore power and burner should start.
If operation is not as described as above, check
wiring and controls.

Information in above table uses Beckett model AFG burner for model numbers SFM4150-5200 and Beckett model
SMG for models 6225 and 7275.
PREVENTIVE MAINTENANCE of an oil red
boiler reduces operating costs. The boiler and vent
pipe should be inspected for accumulation of soot
or scale deposits periodically but at least once every
year before the start of each heating season. When
soot is present on the section walls and ueways,
improper combustion will result, causing additional
sooting and scaling until ueways are completely
closed. To remove soot and scale from the ueways,
remove top jacket panel, top clean-out plate, open
burner swing door. (See Figure #9 next page)
PERIODIC INSPECTION and tightening of the
tankless heater/cover plate bolts will reduce the risk
of leaks. See part number 6, in Figure #14, Replace-
ment Parts “Heat Exchanger” section in the back of
this manual.

OPERATING INSTRUCTIONS

16
Using a ue brush, brush the soot and scale into the
combustion space where it can be removed through
the swing door opening.
It is recommended to replace the nozzle at the start
of each heating season. Lubricate the burner motor
and circulator motor - if required - with a few drops
of a good grade of light motor oil. Do not over oil.
Have a competent service person service the burner
and check the controls and check the electrodes for
carbon or cracks in the insulators. Burners should be
adjusted to produce the conditions shown in Start-
up and Adjustment of Oil Burner procedure covered
earlier in this section.
