Hazard denitions
The following dened terms are used throughout this manual to bring attention to the presence of hazards of
various risk levels or to important information concerning the life of the product.
Indicates an imminently hazardous situation which, if not avoided, will result in death, serious injury or substantial property damage.
Indicates a potentially hazardous situation which, if not avoided, could result in death, serious injury or substantial property damage.
2
Indicates a potentially hazardous situation which, if not avoided, may result in moderate or minor injury or property damage.
Indicates special instructions on installation, operation, or maintenance which are important but not related to personal injury hazards.
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.
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 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.
Return water cannot be lower than 135°F for prolonged periods of time. Operation under these conditions will result in sustained condensing within the combustion chamber and potentially reduce boiler longevity. In addition, the return water cannot be introduced into the boiler if it is more than 40°F less than the idle boiler temperature. Continued operation under these conditions may result in premature boiler failure through thermal shock. Example: A boiler that has been idle for some time since the last heat demand cycle may have it’s boiler water temperature reduced to 150°F. The return temperature from the next zone activation cannot be less than 110°F. If the above conditions exist, an RTC (or similar type of control system) system must be installed to protect the boiler from sustained condensing operation and thermal shock. See separate RTC Manual, P/N 8146382.

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 No. 2 fuel oil,, 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.
Probe and Float type low water cutoff devices require annual inspection and maintenance. Refer to
instructions in Section V, Paragraph C for inspection and cleaning instructions.
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.
All V11H Series 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 V11H 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 V11H are as follows:
MAWP, Steam - 15 psi MAWP, Water (USA) - 80 psi MAWP, Water (Canada) - 50 psi
It is common and acceptable practice to install these boilers in lower pressure systems, below the boiler MAWP. Therefore, Burnham Commercial offers safety relief valves set at or below the MAWP of the boiler. See Table 1 for available safety relief valve set pressures.

Important Product Safety Information
Refractory Ceramic Fiber Product
The Repair Parts list designates parts that contain refractory ceramic fibers (RCF). RCF has been classified as a possible human carcinogen. When exposed to temperatures above 1805°F, such as during direct flame contact, RCF changes into crystalline silica, a known carcinogen. When disturbed as a result of servicing or repair, these substances become airborne and, if inhaled, may be hazardous to your health.
AVOID Breathing Fiber Particulates and Dust
Precautionary Measures:
Do not remove or replace RCF parts or attempt any service or repair work involving RCF without wearing the following protective gear:
1. A National Institute for Occupational Safety and Health (NIOSH) approved respirator
2. Long sleeved, loose fitting clothing
3. Gloves
4. Eye Protection
Take steps to assure adequate ventilation.
Wash all exposed body areas gently with soap and water after contact.
Wash work clothes separately from other laundry and rinse washing
machine after use to avoid contaminating other clothes.
Discard used RCF components by sealing in an airtight plastic bag. RCF and crystalline silica are not classified as hazardous wastes in the United States and Canada.
First Aid Procedures:
If contact with eyes: Flush with water for at least 15 minutes. Seek
immediate medical attention if irritation persists.
If contact with skin: Wash affected area gently with soap and water.
Seek immediate medical attention if irritation persists.

A. INSPECT SHIPMENT carefully for any signs of
damage.
1. ALL EQUIPMENT is carefully manufactured, inspected and packed. Our responsibility ceases upon delivery of crated Boiler to the carrier in good condition.
2. ANY CLAIMS for damage or shortage in shipment must be led immediately against the carrier by the consignee. No claims for variances from, or short­age in orders, will be allowed by the manufacturer unless presented within sixty (60) days after the receipt of goods.
B. LOCATE THE UNIT
Recommended clearance for service may be reduced to minimum clearance to combustible material. However, increased service and
maintenance difculty will result.
1. RECOMMENDED SERVICE CLEARANCE
- Locate the unit in the boiler room so as to provide ease of venting and adequate clearance for maintenance, serviceability, and installation of piping. Refer to Figure 1 for boiler dimensional data.
FRONT --- Provide 54" service clearance for
removal, maintenance, and servicing of burner and controls.
REAR --- Provide a minimum service clearance
from the boiler jacket for access to pressure relief door, ame observation port, rear ue damper and vent piping, relief valve, and boiler return piping. See following chart.
LEFT SIDE --- Provide a minimum clearance from
the boiler jacket of 36" for cleaning of ueways.
RIGHT SIDE --- Less Tankless Heater - Provide a
minimum clearance from boiler jacket of 12".
With Tankless Heater - Provide a minimum
clearance from the boiler jacket of 35" for installation and removal of tankless heater(s).
TOP --- Provide a minimum clearance from the
boiler jacket of 24".
2. FOR MINIMUM CLEARANCES to combustible materials, See Table II.
3. PROVIDE ADEQUATE FOUNDATION for the

Table III: Recommended Rear Service Clearance
Figure 2: Boiler Foundation
This boiler is NOT suitable for installation on
combustible oor.
Floor construction should have adequate load
bearing characteristics to bear the weight of
the boiler lled with water (see Table 1). A
boiler foundation similar to the one shown in Figure 2 is recommended if the boiler room
oor is weak or uneven or if a water condition
exists.
4. PROVIDE AIR SUPPLY AND VENTILATION to accommodate proper combustion.
Failure to supply adequate air to the boiler will
result in unsafe boiler operation.
For commercial and industrial equipment,
permanent facilities for supplying an ample amount of outside air shall be provided in accordance with the following.
For boiler rooms adjacent to outside walls, and
where combustion air is provided by natural ventilation from the outside, there shall be a permanent air supply inlet having a total free area of not less than 1 sq. in. per 4,000 Btu per hr. (35 sq. in. per gal. per hr.) (5.5 cm2 per kw.) of total input rating of the burner or burners and in no case less than 35 sq. in. (0.425 m2).
For boiler rooms not adjacent to outside walls,
the combustion air shall be supplied in a manner acceptable to the authority having jurisdiction. a. In the absence of local requirements, the
conned space shall be provided with two
permanent openings, one in or near the top of the room and one near the bottom. The openings shall communicate by means of ducts, with the outdoors or to such spaces (crawl or attic) that communicate with the outdoors.
i. Where communicating by means of vertical
ducts, each opening shall have a free area of not less than 1 sq. in. per 4,000 Btuh (35 sq. in. per gph.) (5.5 cm2 per kw) of total input rating of all appliances in the enclosure.
ii. If horizontal ducts are used, each opening
shall have a free area of not less than 1 sq. in. per 2,000 Btuh (70 sq. in. per gph.) (11
2
cm
per kw) of total input of all appliances
in the enclosure.
5. CHIMNEY OR VENT
When a V11H gas red boiler is connected to
a venting system that is designed so that it will operate under a negative pressure, the use of Type C, B, or other manufactured vent systems designed for negative pressure is acceptable.
When a V11H oil red or combination gas/oil red boiler is connected to a venting system
that is designed so that it will operate under a negative pressure, the use of Type C, L or other manufactured vent systems designed for negative pressure is acceptable.
Unlined masonry chimneys are not accept­able. Lined masonry chimneys are acceptable with the appropriate vent connectors using materials described above.
11
When a V11H gas red boiler is connected
to a venting system that is designed so that it will operate under a positive pressure, manufactured vent systems, designed and approved for positive pressure application per UL1738, must be used (for example, Van-Packer model CS, Protech Model FasNSeal / FasNSeal
W2, Heatfab Saf-T-Vent or equivalent).
When a V11H oil red or combination gas/oil red boiler is connected to a venting system
that is designed so that it will operate under a positive pressure, manufactured vent systems, designed and approved for positive pressure application, must be used (for example, Selkirk Metalbestos Model PS / IPS,
Van-Packer Model ES or equivalent).
The V11H Series boiler is designed for forced draft
ring and may be used with a conventional natural draft stack (15’ minimum height) or a stub vent, sometimes called a diesel stack (see Figure 3a). See Table I for the proper vent outlet size. For low silhouette vent terminations, see Figure 3b. Draft controls are not normally required, although they may be used on installations where a natural draft stack is used or on multiple boiler installations with a common stack. The boiler is provided with a breeching damper, which should be adjusted to maintain a positive pressure of 0.1” W.C. in the vent connector box during burner high re operation (see breeching pressure sensing port in Figure 1).
Figure 3a: Typical Arrangement For Stub Vent
If the venting system is designed for positive or forced
draft venting, the boiler, vent connector and stack will operate under positive pressure. Gas tight vent systems designed for pressure systems must be used to prevent ue by-product leakage. The vent height is usually limited to prevent negative draft, typically three (3) feet above the roof line (see Figure 3a). The damper shall be adjusted to maintain a positive pressure of 0.1” W.C. in the vent connector box during burner high re operation (see breeching pressure sensing port in Figure
1).
If the venting system is designed for negative pressure
(natural draft), the boiler still operates with positive pressure in the chamber and up to the xed damper on the ue collar. However, if the venting system is larger than what is required, the stack will provide a surplus draft (or negative pressure) that may require the use of a barometric damper to maintain the positive 0.1” W.C. pressure at the ue outlet. Multiple forced draft boiler stacks should always be designed as negative to ensure the products of combustion do not exit a boiler that is not ring.
Venting instructions are guidelines only. Consult a venting expert on the design of a specic vent
system for your application. The ASHRAE Venting Guide and The National Fuel Gas Code, NFPA 54 should be considered in all venting systems.
Conventional vent material may not be suitable for the application. Flue gases can leak carbon monoxide from the joints on these materials and can result in severe personal injury or death.
Installations having long horizontal runs or an excessive amount of tees or elbows will restrict the ow of combustion gases and can result in condensation, ue gas leakage of carbon monoxide, resulting in
severe personal injury or death.

VENT SIZING - Area must be the same as or greater than the boiler breeching (Smoke Outlet). A barometric damper may be required on installations with a high draft condition.
1. If improper vent is suspected, remove pipe at breeching and operate boiler. This will determine if excessive down draft, blocked or restricted ue, etc. is causing the problem.
2. If using type shown in A above, be sure cap is raised sufciently above main pipe to allow ue gases to vent unimpeded.

SECTION II - CAST IRON BLOCK ASSEMBLY
A. FACTORY ASSEMBLED SECTIONS - The
assemblage should be set in the proper location as outlined in Section I. Lifting arrangement and weights are given in Figure 4.
THEN THE DRAW-UP ROD NUTS SHOULD BE
LOOSENED UNTIL FINGER TIGHT AND THEN TIGHTENED ½ TURN WITH A WRENCH. Now proceed to Paragraph C of this section, “HYDRO­STATIC TEST”.
B. FIELD ASSEMBLED SECTIONS - If the boiler
was ordered to be eld assembled, follow the assembly procedure outlined on the following pages.
1. ASSEMBLY OF SECTIONS (MANUAL DRAW-UP)
These sections are designed to be drawn together
one section at a time using the 11" long draw-up rods (provided) and ordinary hand tools.
Tools required: (1) ¾" Drive Ratchet (1) 1¼" Socket (1) 1¼" Combination or Open End Wrench (1) Can Thread Cutting Oil or Grease
WHEN ASSEMBLING SECTIONS WITHOUT
HYDRAULIC DRAW-UP EQUIPMENT, NEVER ASSEMBLE MORE THAN ONE SECTION AT A TIME.
a. Place the rear section in its approximate nal
position, as outlined in Section I and support it with a suitable prop. See Figure 5.
Figure 5: Positioning of Back Section
14
Figure 4: Lifting Instruction
b. On sizes 1104 thru 1106 only - Open target wall
carton, apply silastic to back of target wall and secure target wall to rear section.
c. Clean the groove in the ground joint along the
edge of the section with the wire brush.
d. Open the Boiler Assembly Carton(s) and remove
the bottle of adhesive. Using the dauber supplied in the bottle, apply the adhesive to the groove. Be sure to use enough adhesive to sufciently coat the entire groove surface. If so desired, a multi-purpose spray adhesive (supplied by others) may be used instead. HOWEVER, GREAT CARE MUST BE TAKEN TO ENSURE THAT THE ADHESIVE DOES NOT COME IN CONTACT WITH THE NIPPLES OR NIPPLE PORTS.
e. While the adhesive is becoming tacky, clean the
nipples and nipple ports thoroughly with a de­greasing 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 nipple ports. Use approximately 25 ml of Loctite #592 per ueway [(1) 7" and (2) 3" nipples and their (6) corresponding nipple ports].
f. Drive nipples squarely into section using
block of wood and hammer, or preferably, an aluminum head hammer. Burnham Commercial offers a polyethylene block for setting the nipples (part no. 8052601). Place block over entire nipple edge and hit the wood with the hammer.
droop or hang outside of the groove. When the end of the groove is reached, cut off the excess rope. Push the length of the excess rope into the groove at the top corner of the section face end of the groove is reached, cut off the excess rope. Push the length of the excess rope into the groove at the top corner of the section face (opposite of the 7" nipple port). Cut off and discard any remaining rope after groove is lled. See Figure 7.
i. From the "Section Arrangement" chart, select
the next section according to the "Identication Code" at the top of the chart. See Figure 8.
Nipples must be driven in evenly and to the proper depth to assure tight joints. Most nipple leaks are caused by tilted or cocked nipples.
DO NOT use steel/iron head hammer to drive nipples without using a wood block. Nipple damage may result.
g. A special nipple setting gauge is provided for the
nipples. Gauge nipple at 90° angles to insure that it is driven to the proper depth into the nipple opening (nipple port). Cut-out in gauge must rest on nipple, with the legs of the gauge touching nished face of section, when nipple is properly driven. See Figure 6.
h. Remove a 127" length of berglass rope from
the assembly carton. Starting with the area around the upper 7" nipple port, rmly press the rope into the groove, so that the adhesive holds it in place. (If more than 25 minutes have passed since the adhesive was applied, it may be necessary to reapply.) Continue to afx the rope to the groove in this fashion around the perimeter of the section. Make sure that the rope does not

NOTES: 1. Chart depicts steam boiler with maximum number of 'CT' Sections.
2. (u) Denotes location of Center Section to which Canopy 'J' Bolts are attached to lugs on the casting. If a lug is broken or missing, casting
must be relocated to an alternate location in the assembly.
3. (l) Denotes location of Single 'CX' Center Section required on water boilers.
4. (n) Denotes location of 'C' Center Section to which jacket support brackets must be attached during block assembly, see Figure 10 for
bracket details.
5. For boilers less tankless water heaters, replace the 'CT' Sections with 'C' Sections.
The sections must be assembled according to the arrangement shown to ensure proper operation, proper assembly of canopy, jacket and alignment of piping and tankless heaters with jacket knockouts. Start with the back section and work towards the front.
Use a brush to clean the groove in the face of
the next section. Then, using a cartridge of RTV 6500 or RTV 736 sealant in a caulking gun, ll the groove in this section with the silastic sealant. Touch-up any missed spots before draw-up. Touch-up after draw-up has no value.
This is a forced draft red boiler and sealant must be applied where specied for proper
and safe performance. Burnham Commercial has approved section joint sealants (silastics) manufactured by Dow-Corning under the product number RTV 736, and Sil-Bond under the product number RTV 6500.
Sections must be drawn-up tight immediately after properly applying sealant for best results. Although sections may be joined within two (2) hours of applying sealant, humidity and temperature affect cure time. If a “thick skin” has been formed on the sealant bead, remove and re-apply sealant.
Sealant must be properly applied to ALL boiler joints. Failure to properly seal the boiler joints will result in combustion gas leaks through the joint. DO NOT operate boiler with combustion gas leaks.
j. Clean and lubricate nipple ports on next section
to be assembled and place on nipples previously installed in rear section. To facilitate assembly, it is advisable to enter the upper nipple rst in its port. Then enter the lower nipples in their respective ports. If necessary, place a lifting bar (crowbar) under the center of the section and lift the nipple port onto the upper nipple. Drive section in place with a heavy block of wood, striking blows as squarely as possible over nipple ports.
k. Large draw-up rod lugs with dual holes are cast in
the four corners of each casting. STARTING WITH THE UPPER HOLES, install four 3/4" x 11" lo ng draw-up rods along with washers and nuts (see Figure 9).
Figure 9: Connection Inspection Locations and
Manual Draw-Up Tie Rod Pattern
To avoid damage to the draw-up rod threads while drawing up sections, apply oil or other lubricant to tie rod threads while assembling sections to prevent stripping of threads on rod and to make assembling easier.
l. DRAW UP SECTION SLOWLY AND
EVENLY using an alternating pattern starting with the upper right lug (closest to the 7" port) and proceeding to the lower left , lower right and nishing with upper left lug. When you start, grind surfaces between adjoining sections should be approximately 3/8” apart. Use three (3) or four (4) passes at tightening the four (4) draw-up rods a little at a time so that sections are pulled up evenly. During the last pass, pay close attention to the silastic sealant as it squeezes when the sections come in close contact. The silastic sealant should continue to squeeze out wafer thin until the sections are connected metal to metal. If the silastic has stopped squeezing out from the connection and the sections still do not appear to be drawn metal to metal, use a feeler gauge to measure any gaps at the locations identied in Figure 9. (Unless specied otherwise, gaps should be measured at these locations on both sides of the sections). A maximum gap of .025" is acceptable. Measure gaps at the outer edge of the connection only, making sure not to puncture the gasket created by the silastic and rope.
17
When tightening the draw-up nuts, DO NOT EXCEED 165 FT-LB OF TORQUE. If the maximum
torque limit has been reached and a gap greater
than .025” still exists between the sections,
consult the regional ofce.
KEEP NIPPLES ALIGNED WITH NIPPLE
PORTS. If necessary, tap edge of nipples lightly with a blunt tool or rod to keep nipples from cocking while sections are being drawn-up. DO NOT DRAW UP SECTION WHEN NIPPLES ARE COCKED. If the torque required becomes excessive, periodically place a heavy block of wood over each nipple port and strike as squarely as possible with several blows to relieve tension on the draw-up rods.
m. CONTINUE ASSEMBLING SECTIONS IN
THEIR RESPECTIVE ORDER alternating the draw-up rods from the upper to lower set of holes in draw-up lugs. Be certain that all sections are drawn up IRON-TO-IRON at all three (3) nipple ports.
BE SURE TO APPLY THE FIBERGLASS
ROPE AND SEALANT to the grooves in the ground joints between adjacent sections as the boiler operates with a positive pressure in the rebox and products of combustion will escape between sections unless they are properly sealed. The rope and sealant should be applied before each section is placed on the assembly.
JACKET SUPPORT BRACKETS must be attached to the appropriate center section during the assembly process on boiler sizes V1113H thru V1123H. Check "Section Arrangement" Chart for location of center section to which jacket support brackets must be attached (see Figure 8 on Page
16).
i. LOCATE JACKET INTERMEDIATE
PANEL MOUNTING BRACKETS NO. 1, NO. 2 AND NO. 3 IN JACKET CARTON. Brackets are shipped at and must be formed by hand, bend as shown in Figure 10.
ii. WHEN APPROPRIATE SECTION is
being assembled to block, slide brackets over draw-up rod lugs prior to inserting draw-up rods, washers and nuts. To prevent the brackets from turning during the draw-up process, insert a large punch or draw-up rod through second hole in each

bracket. Refer to Figures 11 and 12 for proper location of each bracket and typical attachment.
n. If a joint springs apart it must be re-drawn tight
within four (4) hours of the time of application of Silastic to that joint.
o. EXCESS LENGTH OF DRAW-UP RODS
must not extend beyond front and rear sections to ensure proper t of jacket, adjust accordingly.
p. AFTER ALL SECTIONS HAVE BEEN
DRAWN UP, THE DRAW-UP ROD NUTS SHOULD BE LOOSENED UNTIL FINGER TIGHT AND THEN TIGHTENED ½ TURN WITH A WRENCH.
q. Now Proceed to Paragraph C of this section,
Hydrostatic Test.
2. ASSEMBLY OF SECTIONS (HYDRAULIC DRAW-UP)
V1104H through V1112H Section Assemblies
The entire assemblage may be drawn-up at one time
using the hydraulic draw-up equipment providing the operation is completed within four (4) hours after application of the sealant.
V1113H through V1123H Section Assemblies
The total assemblage should be rst drawn-up into
two (2) sub-assemblies. Each sub-assembly may be drawn-up at one time using the hydraulic draw-up equipment providing the operation is completed within four (4) hours after the application of the sealant.
"Hydraulic Draw-Up Equipment" is available
through Burnham Commercial by ordering part number 6196008.
a. Repeat steps 1a through 1j under "Field
Assembled Sections (Manual Draw-Up)".
b. Continue driving sections in place (in their
respective order) until all sections are in the assemblage. Ground surfaces between adjoining
sections should be spaced 1/4" to 3/8" apart. Spacing of more than 3/8" will limit number of sections that can be drawn up in one unit and could indicate cocked nipples.
Sealant must be properly applied to ALL grooves. Failure to properly seal the boiler joints will result in combustion gas leaks through the joint. DO NOT operate boiler with combustion gas leaks. The sealant should be applied before each section is placed on the assembly.
On long boiler assemblies, it may be necessary
to draw up a partial block if the entire boiler is not ready to be drawn up tight within four (4) hours of the rst application of the Silastic. If the block assembly time extends overnight, the partial block completed must be drawn up tight before leaving the boiler overnight. If a joint springs out, it must be re-drawn tight within four (4) hours of rst application of Silastic to the joint.
c. Insert the three 3/4" draw-up rods (and
couplings, if appropriate) through the tapped holes in the rear section extending them through the tapped holes in the front section. Be sure to screw draw-up rods into couplings far enough to prevent stripping threads.
d. Place a 12" long steel channel on each end of the
upper draw-up rod and an 8½” long steel channel on each end of the lower draw-up rods. Install nuts and washers on one end of the draw-up rods and the hydraulic rams, washers and draw-up rod clamps on the other. See Figure 13.
e. Draw-Up Sections
Use hydraulic rams to draw up sections by applying pressure alternately on the draw-up rods. When rams reach stroke limit, release pressure in ram pumps and then move clamps to new position.
19
Do not apply pressure directly on threaded tappings on front and rear sections with draw-up channels during assembly procedures. Rods should be approximately centered in openings so that rods and couplings (when used) do not drag on pipe thread in end section tappings.
READ THE STATEMENTS BELOW BEFORE
ATTEMPTING TO USE HYDRAULIC EQUIPMENT.
Release pressure in ram pumps before attempting to remove clamps.
Do not stand in line with draw-up rods at either end when hydraulic pressure is being applied. As a safety measure, ends of draw­up rods should be covered while sections are being drawn in case rods should snap while under tension.
Do not operate ram against draw-up coupling.
Do not operate pump after ram has reached stroke limit.
f. Continue to draw-up until all sections make
contact at the ground joints.
g. After all sections have been drawn up, but before
removing the hydraulic rams and draw-up rods, the 11" long tie-rods must be installed.
Large draw-up rod lugs with dual holes are cast
in the four (4) corners of each casting. Starting with the upper holes in the back section, install four (4) ¾" x 11" long tie rods along with washers and nuts. Continue installing the tie rods alternating from the upper to lower set of holes in draw-up lugs until front section is secured. Be certain that all sections are drawn up iron to iron at all three nipple ports.
Jacket Support Brackets must be attached to the appropriate center section during this process. Check "Section Arrangement" chart for location of center section to which jacket support brackets must be attached (see Figure 8).
Figure 14: Boiler Section Assemblage
Brackets are shipped at and must be formed
by hand, bend as shown in Figure 10.
ii. Slide brackets over draw-up rod lugs prior
to inserting the 11" long tie rods, washers and nuts. Refer to Figures 11 and 12 for proper location of each bracket and typical attachment method.
h. Excess length of draw-up rods must not extend
beyond front and rear section to ensure proper t of jacket, adjust accordingly. TIGHTEN ALL TIE ROD NUTS UNTIL FINGER TIGHT. THEN TIGHTEN THEM AN ADDITIONAL ½ TURN WITH A WRENCH.
C. HYDROSTATIC TEST - 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.
1. Tankless Heater Installation
If boiler is ordered with tankless heaters, install
heaters with the gaskets provided. Table V gives the maximum number of heaters permissible per assemblage and the heater ratings.
2. Plug all boiler tappings and ll entirely with cold water.
20
i. LOCATE JACKET INTERMEDIATE
PANEL MOUNTING BRACKETS NO. 1, NO. 2, AND NO. 3 IN JACKET CARTON. Brackets are shipped at and must be formed by hand, bend as shown in Figure 10.
DO NOT install gauge until after hydrostatic testing the boiler. Gauge failure may result.
3. All completed boilers shall satisfactorily pass the prescribed hydrostatic test.
a. STEAM BOILERS: The assembled boiler shall
be subjected to a hydrostatic test of not less than 45 psig.
b. HOT WATER BOILERS: The assembled boiler
shall be subjected to a hydrostatic test of not less than 1½ times the maximum allowable working pressure, as established by the relief valve provided with the boiler. For example, a boiler with a 50 psi relief valve must be subjected to a test pressure of 75 psig to 85 psig.
Failure to properly hydrotest all boilers at the correct pressure may result in section assembly failure in operations.
4. 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.
5. After making certain that there are no leaks, drain boiler and remove plugs for boiler trim and other connections.
