THIS BOILER HAS A LIMITED WARRANTY, A COPY OF WHICH IS PRINTED ON THE BACK OF THIS MANUAL.
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is complete. The warranty for this boiler is valid only if the boiler
has been installed, maintained and operated in accordance with these instructions.
DO NOT store or use gasoline or other ammable vapors or liquids in the vicinity of this or any other
appliance.
If you smell gas or fuel oil vapors, do not try to operate the burner/boiler system. Do not touch any
electrical switch or use any phone in the building. Immediately call the gas or oil supplier from a remotely
located phone.
Burner/boiler systems produce steam or hot water in a pressurized vessel by mixing extremely ammable
gaseous, liquid or solid fuels with air to produce combustion and very hot products of combustion.
Explosions, res severe personal injury, death and/or property damage will result from improper, careless
or inadequate installation, operation or maintenance of fuel-burning and boiler equipment.
IMPORTANT INFORMATION -
READ and save these instructions for reference

3
Improper installation, adjustment, alteration, service or maintenance can cause property damage, personal
injury or loss of life. Failure to follow all instructions in the proper order can cause personal injury or
death. Read and understand all instructions, including all those contained in component manufacturers
manuals which are provided with the appliance before installing, starting-up, operating, maintaining or
servicing this appliance. Keep this manual and literature in legible condition and posted near appliance
for reference by owner and service technician.
This boiler requires regular maintenance and service to operate safely. Follow the instructions contained
in this manual.
Installation, maintenance, and service must be performed only by an experienced, skilled and knowledgeable
installer or service agency.
All heating systems should be designed by competent contractors and only persons knowledgeable in
the layout and installation of hydronic heating systems should attempt installation of any boiler.
It is the responsibility of the installing contractor to see that all controls are correctly installed and are
operating properly when the installation is completed.
Installation is not complete unless a pressure relief valve is installed into the specied tapping on the
supply manifold located on top and at rear of appliance - See Section III, Paragraph 33, ‘e’ of this manual
for details.
This boiler is NOT suitable for installation on combustible ooring.
Do not tamper with or alter the boiler or controls. Retain your contractor or a competent serviceman to
assure that the unit is properly adjusted and maintained.
Clean boiler at least once a year - preferably at the start of the heating season to remove soot and scale.
The inside of the combustion chamber should also be cleaned and inspected at the same time.
Have Burner and Controls checked at least once a year or as may be necessitated. Do not operate
unit with jumpered or absent controls or safety devices. Do not operate unit if any control, switch,
component, or device has been subject to water.

4
Appliance materials of construction, products of combustion and the fuel contain alumina, silica, heavy
metals, carbon monoxide, nitrogen oxides, aldehydes and/or other toxic or harmful substances which
can cause death or serious injury and which are known to the state of California to cause cancer, birth
defects and other reproductive harm. Always use proper safety clothing, respirators and equipment when
servicing or working nearby the appliance.
This boiler contains very hot water under high pressure. Do not unscrew any pipe ttings nor attempt
to disconnect any components of this boiler without positively assuring the water is cool and has no
pressure. Always wear protective clothing and equipment when installing, starting up or servicing this
boiler to prevent scald injuries. Do not rely on the pressure and temperature gauges to determine the
temperature and pressure of the boiler. This boiler contains components which become very hot when
the boiler is operating. Do not touch any components unless they are cool.
This appliance must be properly vented and connected to an approved vent system in good condition.
Do not operate boiler with the absence of an approved vent system.
This boiler needs fresh air for safe operation and must be installed so there are provisions for adequate
combustion and ventilation air.
The interior of the venting and air intake systems must be inspected and cleaned before the start of the
heating season and should be inspected periodically throughout the heating season for any obstructions.
Clean and unobstructed venting and air intake systems are necessary to allow noxious fumes that could
cause injury or loss of life to vent safely and will contribute toward maintaining the boiler’s efciency.
This boiler is supplied with controls which may cause the boiler to shut down and not re-start without
service. If damage due to frozen pipes is a possibility, the heating system should not be left unattended in
cold weather; or appropriate safeguards and alarms should be installed on the heating system to prevent
damage if the boiler is inoperative.
This boiler is designed to burn natural and/or LP gas only. Do not use gasoline, crankcase drainings, or
any oil containing gasoline. Never burn garbage or paper in this boiler. Do not convert to any solid fuel
(i.e. wood, coal). All ammable debris, rags, paper, wood scraps, etc., should be kept clear of the boiler
at all times. Keep the boiler area clean and free of re hazards.
Float type low water cutoff devices require annual inspection and maintenance. Refer to instructions in
Section V, Paragraph 7 for inspection and cleaning instructions.
Series 5B cast iron boilers are designed, built, marked and tested in accordance with the ASME Boiler and
Pressure Vessel Code, Section IV, Heating Boilers. An ASME Data Label is factory applied to each Series 5B
jacket, which indicates the boiler Maximum Allowable Working Pressure (MAWP). Each cast iron section is
permanently marked with the MAWP listed on the boiler’s ASME Data Label. Those values for the Series 5B
are as follows:
MAWP, Water - 50 PSI
MAWP, Steam - 15 PSI

SECTION II – GENERAL INFORMATION
1. BOILER INSTALLATION must conform to the
requirements of the authority having jurisdiction, or in
the absence of such requirements, to:
USA – “National Fuel Gas Code, ANSI Z223.1”.
When required by the authority having jurisdiction,
the installation must conform to American Society of
Mechanical Engineers Safety Code for Controls and
Safety Devices for Automatically Fired Boilers, No.
CSD-1.
CANADA – “Installation Codes for Natural and
Propane Gas Burning Appliances and Equipment,
CAN/CSA-B149 (.1 or .2)”.
DO NOT INSTALL THIS BOILER ON CARPETING.
2. BOILER LOCATION – locate on a level NON-
COMBUSTIBLE FLOOR as close as possible to
chimney so that vent connection is short and direct.
Boiler must not be installed directly on
combustible ooring. A concrete pad is not
sufcient to protect combustible ooring.
The boiler shall be installed such that the gas ignition
system components are protected from water (dripping,
spraying, rain, etc.) during boiler operation and service
(circulator replacement, control replacement, etc.).
Do not install boiler where gasoline or other ammable
vapors or liquids, or sources of hydrocarbons (i.e.
bleachers, cleaners, chemicals, sprays, paint removers,
fabric softeners, etc. ) are used or stored.
Refer to table below for minimum clearances, service
clearances, and clearances for removal of Tankless
Heaters.
3. PROVIDE COMBUSTION AND VENTILATION
AIR.
In the USA refer to National Fuel Gas Code, NFPA
54/ANSI Z223. Section 5.3, Air for Combustion and
Ventilation. In Canada refer to Natural Gas Installation
Code, CAN/CSA-B149.1 – latest edition or Propane
Installation Code, CAN/CSA-B149.2 – latest edition.
Local code provisions may apply and should be
referenced.
Adequate combustion and ventilation air must be
provided to assure proper combustion.
a. Determine volume of space (boiler room). Rooms
communicating directly with the space, in which
the appliances are installed, through openings not
furnished with doors, are considered a part of the
space.
Volume (ft³) = Length (ft) x Width (ft) x Height (ft)
b. Determine total input of all appliances in the space.
Add inputs of all appliances in the space and round
the result to the nearest 1000 Btu per hour.
c. Determine type of space.
Divide Volume by Total Input of all appliances
in space. If the result is greater than or equal to
50 ft³/1000 Btu per hour, then it is considered an
unconned space.
If the result is less than 50 ft³/1000 Btu per hour,
then the space is considered a conned space.
d. For boiler located in an unconned space of a
conventionally constructed building, the fresh
air inltration through cracks around windows
and doors normally provides adequate air for
combustion and ventilation.
e. For boiler located in a conned space or an
unconned space in a building of unusually tight
construction, provide outdoor air with the use
of two permanent openings which communicate
directly or by duct with the outdoors or spaces
(crawl or attic) freely communicating with the
outdoors. Locate one opening within 12 inches of
top of space. Locate remaining opening within 12
inches of bottom of space. Minimum dimension
of air opening is 3 inches. Size each opening per
following:
1. Direct communication with outdoors. Minimum
free area of 1 square inch per 4,000 Btu per hour
input of all equipment in space.
2. Vertical ducts. Minimum free are of 1 square
inch per 4,000 Btu per hour input of all
CLEARANCES - From Table below and from dimensional data in Fig. 1, determine BOILER ROOM space necessary for appropriate access
to and servicing of Boiler. Consideration should be given to other appliances installed in the same area. Consult with local Building and
Safety Codes for compliance.

shall be same as opening free area.
3. Horizontal ducts. Minimum free area of 1
square inch per 2,000 Btu per hour input of all
equipment in space. Duct cross-sectional area
shall be same as opening free area.
Alternate method for boiler located within
conned space. Use indoor air if two permanent
openings communicate directly with additional
space(s) of sufcient volume such that combined
volume of all spaces meet criteria for unconned
space. Size each opening for minimum free area
of 1 square inch per 1,000 Btu per hour input of
all equipment in spaces, but not less than 100
square inches.
4. LOUVERS AND GRILLES of Ventilation Ducts
All outside openings should be screened and louvered.
Screens used should not be smaller than ¼ inch mesh.
Louvers will prevent the entrance of rain and snow.
a. Free area requirements need to consider the blocking
effect of louvers, grilles, or screens protecting the
openings. If the free area of the louver or grille
is not known, assume wood louvers have 20-25
percent free area and metal louvers and grilles have
60-75 percent free area.
b. Louvers and grilles must be xed in the open
position or interlocked with the equipment to open
automatically during equipment operation.

Boiler is to be installed.
d. Join Base Sub-assemblies together (15 section &
larger boilers) by rst removing upper shipping
strip and lower shipping angles from subassemblies.
Use (4) ¼”-20 x ¾” MS, nuts and washers to attach
subassemblies, see Fig. 3.
e. Attach Front Intermediate Jacket Panel Support
Bracket and Lower Rear Intermediate Panel Support
Bracket to lower channel on Front Base Frame and
Rear Base Frame, respectively, using (4) ¼”-20 x
¾” MS, nuts and washers.
f. Base must be level in both directions and secure on
the oor. Shim and grout under Base if necessary.
g. Place cardboard covering over the top of the burner
assembly to protect them during the assembly of the
boiler sections.
2. CLEAN BOILER SECTIONS inside and out to remove
dirt due to shipment and handling.
Open Tie Rod Bundle(s). Open Draw-up Rod
Bundle(s).
Open Boiler Assembly Carton(s).
3. SET LEFT END SECTION ON BASE so that locating
lugs on bottom of section go inside Front and Rear Base
Frames. Slide section on base until these lugs strike
High Base End Panel at left end of Base, see Fig. 4.
(Note – if High Base End Panel is at right end of Base,
section assembly must start with Right End Section).
Left end sections are identied by “LEH” cast on
section; Right End Sections are identied by “REH”
cast on section.
4. CLEAN NIPPLES AND NIPPLE PORTS thoroughly
with a de-greasing solvent. Use the Loctite® #592
supplied to lubricate the nipples and nipple ports.
Apply the lubricant to the nipples and nipple ports, then
use a brush to disperse it evenly around the nipples and
the nipple ports. Use approximately 25 ml of Loctite®
#592 per ueway [(1) 7” and (2) 3” nipples and their
(6) corresponding nipple ports]. Use Nipple Gauge
furnished – follow instructions included with gauge to
set nipples. USE ALL PRECAUTIONS TO AVOID
COCKED NIPPLES.
5. PAINT ALL GROUND SURFACES of each section
with the Sealer Compound furnished.
6. ASSEMBLE CENTER SECTIONS. Refer to Fig. 6
for proper location of Tapped, and sometimes plugged,

nipple ports on both sections, see Fig. 5.
d. Place two (2) at washers, draw-up channel and a
nut on each end of draw-up rods and nger tighten.
e. DRAW UP CENTER SECTION SLOWLY AND
EVENLY, tightening each DRAW-UP ROD a little
at a time so that sections are equally spaced. KEEP
NIPPLES ALIGNED WITH NIPPLE PORTS. If
necessary, tap Nipples lightly with a blunt tool or
rod to keep Nipples from cocking while Sections are
being drawn up. DO NOT DRAW UP SECTION(S)
WHEN NIPPLES ARE COCKED. Continue
tightening Draw-Up Rods equally until Sections
meet iron-to-iron on the ground surface. BUMPING
OUTER EDGES OF SECTION WITH WOODEN
BLOCK WILL EASE DRAW-UP OPERATION.
f. KEEP DRAW-UP ROD THREADS, NUTS AND
WASHERS LUBRICATED with grease or heavy oil
to prevent damage to rods and threads and to make
assembling easier.
g. USING A PINCH BAR, insert WOOD WEDGES
under last Center Section assembled so as to raise
it just above Boiler Base. This will keep the next
section to be assembled above the base, thus making
it easier to join and draw-up. MOVE WOOD
WEDGES FORWARD EACH time a Section has
been drawn up.
7. ASSEMBLE REMAINING END SECTION WITH
DRAW-UP RODS in a manner similar to that for
assembling Center Sections. Remove wedges from
under Boiler. Be sure Boiler is aligned and seated on
Base.
a. After section assembly is completed install 5/8” tie
rods from tie rod bundle through the upper lug holes
in the front of Boiler and Lower lug holes in the rear
of Boiler sections and tighten until they are nger
tight only, to allow for expansion. This is necessary
in order to allow clearance for installation of Flue
cover plates. Finally, remove ¾” draw-up rods from
nipple ports.

10. HYDROSTATIC TEST, see Fig. 9: After the boiler
sections have been assembled, it is essential that the
boiler be hydrostatically tested before the canopy, ue
cover plates, jacket, or piping is installed.
a. Plug all boiler tappings and ll boiler completely
with cold water.
DO NOT install gauge until after hydrostatic
testing the boiler. Gauge failure may result.
b. All completed boilers must satisfactorily pass the
prescribed hydrostatic test.
(1) STEAM BOILERS: The assembled boiler must
be subjected to a hydrostatic test of 45 psig to 55
psig.
(2) HOT WATER BOILERS: The assembled boiler
must be subjected to a hydrostatic test of 75 psig
to 85 psig.
Failure to properly hydrotest all boilers at the
correct pressure may result in section assembly
failure in operation.
11. EXAMINE BOILER CAREFULLY, INSIDE AND
OUTSIDE, to insure against leaks from cocked nipples
or through concealed breakage caused in shipping and
handling. This precaution is for your protection and
will simplify handling of necessary replacements and
adjustment claims. After making certain that there are
no leaks, drain boiler and remove plugs for boiler trim
and other connections.
Open Boiler Sealing Carton.
12. SEAL BETWEEN BOILER SECTIONS AND BASE,
see Fig. 10.

13. INSTALL FLUE COVER PLATES over cleanout
openings on Front and Rear of Boiler. Use ¼” Carriage
Bolts installed at top and bottom of ue openings and
secure with washer and jam nut to provide a xed
stud. Install ue cover plates over studs with insulation
against Boiler and secure with washers and nuts, see
Fig. 11.
14. CONNECT SUPPLY AND RETURN PIPING TO
HEATING SYSTEM.
CLEARANCES – Steam and Hot water pipes shall
have clearances of at least ½” from all combustible
construction.
Before using copper for steam piping, consider
the following characteristics of copper piping:
1) high coefcient of thermal expansion can
induce mechanical stresses and cause expansion/
contraction noises if not accounted for in the
piping system design and installation,
2) high heat transfer rate (heat loss) of uninsulated
copper piping must be included in the normal
piping and pickup factors used to size the boiler,
3) soldering or brazing pastes and uxes that end
up in the system can cause poor heat transfer,
surging, and unsteady water line and wet steam
if not thoroughly removed during the boil out
procedure and,
4) galvanic corrosion of the adjoining metal may
occur due to dissimilar metals in certain water
chemistries if dielectric unions are not used.
a. With Steam Heating System, refer to Fig. 12, 13, 14
or 15.
b. With Forced Circulation HOT WATER HEATING
SYSTEMS, see Fig. 16A and 16B. For additional
reference, consult I=B=R Installation and Piping
Guide No. 250.
NOTE: When Hot Water Heating Boilers are
connected to Heating Coils located in Air Handling
Units where they may be exposed to refrigerated
air circulation, the Boiler Piping System must
be equipped with Flow Control Valves or other
automatic means to prevent gravity circulation of
the Boiler Water during the cooling cycle.
c. With COMBINATION HEATING AND COOLING
(REFRIGERATION) SYSTEMS having the same
Distributing Units, Piping and Circulator, See Fig.
17. For additional reference, consult ASHRAE
Systems Handbook 2008 Edition.
d. NOTE: Valves must be installed in the supply and
return branches to the Heating Boiler and Water
Chiller so as to prevent circulation of Chilled Water
through the Boiler or Heated Water through the
Chiller.
OXYGEN CORROSION:
Oxygen contamination of the boiler water will cause
corrosion of the iron and steel boiler components,
which can lead to failure. As such, any system must
be designed to prevent oxygen absorption in the rst
place or prevent it from reaching the boiler. Problems
caused by oxygen contamination of boiler water are not
covered by Burnham’s standard warranty.
