CAUTION

NOTICE

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.

DANGER

DO NOT store or use gasoline or other ammable vapors or liquids in the vicinity of this or any other

appliance.

WARNING

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 located at the rear of

appliance - See Section III of this manual for details.

This boiler is suitable for installation on combustible ooring. Do not install boiler on carpeting. Do not operate on oors where heat affected material is below.

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 combustion chamber should also be cleaned and inspected at the same time. Have Burner and Controls must be 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 must be installed to protect the boiler from sustained condensing operation and thermal shock. See separate RTC Manual, P/N

8146382.

WARNING

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 pressures. 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). Do not convert to any gaseous fuel (i.e. natural gas, LP). 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.

Always keep the oil supply valve shut off if the burner is shut down for an extended period of time.

Probe and oat type low water cutoff devices require annual inspection and maintenance. Refer to

instructions in Section V, Paragraph C for inspection and cleaning instructions.

NOTICE

All V9A 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 V9A 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 V9A are as follows:

MAWP, Steam - 15 psi MAWP, Water (USA) - 80 psi MAWP, Water (Canada) - 45 psi

It is common and acceptable practice to install these boilers in lower pressure systems, below the boiler MAWP. Therefore, Burnham offers safety relief valves set at or below the MAWP of the boiler. See Table 1 for available safety relief valve set pressures.

WARNING

Failure to supply adequate air to the boiler will

result in unsafe boiler operation.

C. PROVIDE AIR SUPPLY AND VENTILATION to

accommodate proper combustion.

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. inch per 4,000 Btu per hr. (35 sq. inch per gallon per hour) (5.5 cm2 per kw.) of total input rating of the burner or burners and in no case less than 35 sq. inch (0.425m2).

For boiler rooms not adjacent to outside walls, the

combustion air shall be supplied in a manner acceptable to the authority having jurisdiction.

1. 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.

a. Where communicating by means of vertical

ducts, each opening shall have a free area of not

less than 1 sq. inch per 4,000 Btuh (35 sq. inch per gph) (5.5 cm2 per kw) of total input rating of all appliances in the enclosure.

b. If horizontal ducts are used, each opening shall

have a free area of not less than 1 sq. inch per 2,000 Btuh (70 sq. inch per gph.) (11 cm2 per kw) of total input of all appliances in the enclosure.

D. CHIMNEY OR VENT

NOTICE

When a V9A 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 V9A 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.

WARNING

When a V9A 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 V9A 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 V9A 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.

WARNING

Venting instructions are recommendations 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.

RAIN CAP

RIGHT

WRONG

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.

3. A popular type cap is shown in B.

4. The tee is frequently used as shown in C.

5. D and E should not be used due to possible uctuations in back pressure.

SECTION II - CAST IRON BLOCK ASSEMBLY

A. FACTORY ASSEMBLED SECTIONS — If the

boiler was ordered with factory assembled sections, the assembly should be set in the proper location as outlined in Section I. Lifting arrangement and weights are given in Figure 4.

1. Proceed to Paragraph C of this Section, “HYDROSTATIC TEST”.

CAUTION

Boiler sections must be drawn-up on perfectly level surface or improper assembly may result.

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 DRAWUP)

These sections are designed to be drawn together,

one section at a time, using the 9¾” long draw-up rods (provided) and ordinary hand tools.

Tools required: (1) ¾” Drive Ratchet (1) 1-1/16” Socket (1) 1-1/16” Combination or Open End Wrench (1) Container of grease, oil or other appropriate

lubricant.

CAUTION

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 and wedges. See Figure 5.

Figure 4: Lifting Instruction

Figure 5: Positioning of Back Section

b. On size V903A 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

nipples and nipple ports thoroughly with a degreasing solvent. Use the Loctite #592 provided 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].

f. Drive nipples squarely into section using

block of wood and hammer, or preferably, an aluminum head hammer. (Burnham offers a Polyethylene Block for setting the nipples, part number 8052601). Place block over entire nipple edge and hit the wood with the hammer.

WARNING

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 legs of gauge touching

nished face of section, when nipple is properly

driven. See Figure 6.

Figure 7: Afxing the Fiberglass Rope

Figure 6: Setting of Nipples

h. Remove a 96” 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 droop or hang outside of the groove. When the end of the groove is reached, cut off the excess rope. Push the length of 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.

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.

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. Use a wire 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 silastic sealant.

Touch-up any missed spots before draw-up. Touch-up after draw-up has no value.

WARNING

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.

NOTES: FOR BOILERS LESS TANKLESS HEATER, REPLACE THE "CT" SECTIONS WITH "C" SECTIONS.

Figure 8: V9A Section Arrangement

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.

k. Drive sections in place with a heavy block of

wood, striking blows as squarely as possible over nipple port.

l. The large draw-up rod lugs with dual holes

are cast in the four (4) corners of each casting. STARTING WITH THE UPPER HOLES, install four (4) 5/8” x 9¾” long draw-up rods along with washers and nuts (see Figure 9).

CAUTION

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.

m. 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.

Figure 9: Connection Inspection Locations and

Manual Draw-Up Tie Rod Pattern

WARNING

When tightening the draw-up nuts, DO NOT EXCEED 150 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.

n. CONTINUE ASSEMBLING SECTIONS IN

THEIR RESPECTIVE ORDER alternating draw-up rods from the upper to lower set of holes in draw-up lugs (see Figure 13). Be certain that all sections are drawn up iron-to-iron at all three (3) nipple ports.

BE SURE TO APPLY THE SEALANT to

the groove 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 the sections are properly sealed. The sealant should be applied before each section is placed on the assembly.

o. If a joint springs apart it must be redrawn tight

within four (4) hours of the time of application of Silastic to that joint.

p. EXCESS LENGTH OF DRAW-UP RODS must

not extend beyond front and rear section to

ensure proper t of jacket, adjust accordingly.

q. After all sections have been drawn up, the

draw-up rod nuts should be loosened until

nger tight and then tightened ½ turn with a

wrench.

r. Now Proceed to Paragraph C of this Section,

Hydrostatic Test.

2. ASSEMBLY OF SECTIONS (HYDRAULIC DRAW-UP)

The entire boiler assembly may be drawn up at one

time using hydraulic draw-up equipment providing the operation is completed within two (2) hours after application of the sealant.

a. Repeat steps 1a through 1k under “Field

Assembled Sections (Manual Draw-Up).”

b. Continue driving sections in place (in their

respective order) until all sections are in the assembly. 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.

WARNING

Sealant must be properly applied to ALL boiler joints. Failure to properly seal the boiler joints will result in combustion gas leaks through to 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 two (2) hours

of the rst application of 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 redrawn tight within four (4)

hours of rst application of Silastic to the joint.

c. Insert the three (3) ¾” 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 3” x 12” lg. steel channel on each end of

the upper draw-up rod and a 3” x 8½” lg. steel channel on each end of the lower draw-up rods.

Refer to Figures 10 and 11 for proper placement

of channel block during assembly procedures. Install nuts and washers on one end of the drawup rods and the hydraulic rams, washers and

draw-up rod clamps on the other. These items are all located in the Draw-Up Kit.

See Figure 12.

CAUTION

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.

WARNING

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 draw-up 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.

Figure 11: Center Section Channel Block Position

(Partial Block Draw-Up)

The large draw-up rod lugs with dual holes cast

in the four (4) corners of each casting. Starting with the upper holes in the back section, install four (4) 5/8” x 9¾” 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.

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 nger tight. Then tighten them an additional ½ turn with a wrench.

Figure 10: Front and Rear Section Channel

Block Positions (Hydraulic Draw-Up)

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.

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 9¾” long tie rods must be installed.

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 IV gives the maximum number of heaters permissible per assembly and the heater ratings.

2. Plug all boiler tappings and ll boiler completely

with cold water.

CAUTION

DO NOT install gauge until after hydrostatic testing the boiler. Gauge failure may result.

3. All completed boilers must satisfactorily pass the prescribed hydrostatic test.

Figure 12: Hydraulic Draw-Up Sections

Figure 13: Boiler Section Assembly

a. STEAM BOILERS: The assembled boiler must

be subjected to a hydrostatic test of 45 psig to 55 psig.

b. HOT WATER BOILERS: The assembled boiler

must 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.

WARNING

Failure to properly hydrotest all boilers at the correct pressure may result in section assembly failure in operation.

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.

J. BURNER INSTALLATION

Refer to burner manufacturer’s installation manual

for proper installation, fuel piping, wiring, burner adjustment, burner start-up and service instructions. Consult Section VI of this manual for burner

specications and burner settings.

K. PACKAGED BOILER

1. The packaged boiler comes on it’s own shipping skid (see Figure 25) and the assembled block is hydrostatically tested at the factory. Once the boiler

is in it’s nal position, perform another hydrostatic

test at 1½ times the working pressure of the boiler. Before boiler is put into service, all draw up rod nuts

should be loosened and then retighten to nger tight

plus 1/2 turn. The shipping skid can be used as a housekeeping pad unless local codes say otherwise. All controls are pre-wired down to the burner. If burner is equipped with a lead lag panel, lead lag controls will be shipped loose for header mounting. The power can be supplied to the burner if equipped

with a control panel. If burner has no panel, the power is supplied to the J-box on the front jacket.

2. SUPPLY CONNECTIONS - Removal of top jacket is not required to connect the supply riser(s),

however one may nd it easier. Refer to Figure

26 or 27 for water boilers and Figure 32 for steam boilers.

3. RETURN CONNECTIONS - The boiler is secured to the shipping skid with U bolts and 3” shipping nipples. Remove the bolts and nipples. Using 3” plugs and an appropriate pipe sealant, plug the unused return connections according to the minimum piping recommendations. Refer to Figure 26 or 27 for water boilers and Figure 32 for steam boilers.

4. If the boiler burner unit was factory re tested, the

burner was adjusted to approximately 10% CO2

(gas) or 12% CO2 (oil) with an over re pressure as listed in the Burner Specications, Section VI of this

manual. Final adjustments should be made once the unit is installed and adjusted.

L. BOILER PIPING - HEATING APPLICATIONS

CONNECT SUPPLY AND RETURN PIPING TO

HEATING SYSTEM

Connect supply and return piping to heating system (see

Figures 26 through 32). Flow direction for hot water boilers must be from the rear return out through the top front supply. Steam boilers can pipe return to the front as an alternate location. Some boiler sizes may require the use of additional supply and return tappings. Check Figure 24 and applicable piping diagram for the boiler size you are installing.

WARNING

Failure to properly pipe boiler may result in improper, unsafe system operation and void manufacturer’s warranty. DO NOT improperly pipe boiler.

WARNING

All steam and hot water pipes must have clearances of at least 1/2” from all combustible construction.

WARNING

A hot water boiler installed above radiation level must be provided with a low water cutoff device as part of the installation.

1. HOT WATER HEATING - This boiler must be installed in strict accordance with this installation manual Deviations from these installation instructions may void manufacturer’s warranty. Also consult I=B=R Installation and Piping Guides.

WARNING

Continued boiler operation for prolonged periods of time under conditions when temperature differential across the system exceeds 40°F and/ or, return water temperature stays below 135°F,

may result in premature boiler failure due to ue

gas condensation and/or thermal shock.

a. If the boiler is used in connection with

refrigeration systems, boiler must be installed with chilled medium piped in parallel with heating boiler using appropriate valves to prevent chilled medium from entering boiler. See Figure

35.

b. If the boiler is connected to heating coils

located in air handling units where they may be exposed to refrigerated air, boiler piping must

be equipped with ow control valves to prevent

gravity circulation of boiler water during cooling system operation.

c. Burnham Commercial recommends maintaining

temperature differential (drop) across the system at 40°F or less, and return water temperature at minimum of 135°F for optimum operation and long-term reliability.

i. If minimum return water temperature can

be maintained at 135°F and temperature differential across the system is at 40°F or less, refer to Figure 26 or 27 for recommended minimum boiler piping details.

ii. If minimum return water temperature cannot

be maintained at 135°F or the temperature differential across the system varies, a blend pump is recommended as a minimum to help

protect the boiler from ue gas condensation

and/or thermal shock. See piping details in Figure 28. Primary secondary piping with a by-pass is an alternate to the blend pump method and is shown in Figure 29.

d. If conditions exist where the boiler is subjected

to prolonged periods of operating conditions below 135°F, other mixing methods such as three or four way valves or variable speed injection should be used. Burnham Commercial offers an RTC Return Temperature Control kit to protect the boiler. See separate RTC manual.

e. Multiple Boilers - Recommended minimum

multiple boiler piping is shown in Figure 30 as primary secondary with a by-pass. The boiler

circulator will maintain a constant ow through

the boiler during every heat demand while the by-pass diverts a portion of hot water back to the return. Alternate minimum multiple boiler piping is shown in Figure 31. The blend pump

will maintain constant ow through the boiler

during every heat demand and provide a hot water blend back to the return.

f. Glycol Antifreeze Solutions - Many systems

today use ethylene or propylene glycol antifreeze solutions as a measure for freeze protection, as well as a pump lubricator and corrosion inhibitor. The properties of the glycol mixture have an impact on valve and pump sizing. All glycol

solutions have a lower specic heat than water.

This means that the glycol solution cannot transfer heat as well as pure water, resulting in

the need for higher ow rates. In addition, the

viscosity of the glycol solution is usually higher than water, requiring a higher pump head for the

same given ow. Consult factory for specic applications, pump selection and ow rate.

WARNING

A properly constructed Hartford Loop must be installed on all gravity return steam systems.

Hartford Loop is not required on pumped return

systems.

2. STEAM HEATING, consult I=B=R Installation and Piping Guide No. 200. For piping details, see Figure 32. Figure 33 shows a typical pumped return/boiler feed unit arrangement. Figure 34 illustrates the required elevations for McDonnell and

Miller 150 and 63 oat low water cut-offs.

M. BOILER PIPING, DOMESTIC HOT WATER

(DHW) APPLICATION – The V9A boiler can be

used in many different piping applications to produce Domestic Hot Water (DHW). In some applications, depending on the control strategy (outdoor reset, setpoint operation, etc.) and size of boiler, it is recommended to isolate the space heating load from the DHW load. For example, if the domestic load is

more than the space heating load, it is benecial to

dedicate one or more boilers solely to DHW production and one or more other boilers to solely space heating, since during mild weather conditions, the boiler(s) will have more capacity than is required. Piped in the recommended manner, the space heating boiler(s) can be shut down during the summer months to conserve energy and to avoid short cycling. This section will address four methods of piping and controlling domestic hot water generation.

1. Hot Water Boiler/Tankless Coil(s) - Tankless coils, mounted into the side of the boiler, have been used successfully for many years and may be used in single and multiple boiler applications. When a boiler is arranged with tankless coils, it is not recommended that outdoor reset be used, unless there are control systems in place to prevent overheating of the space heating zones.

Figure 37a depicts the addition of an automatic

mixing valve to the tankless heater piping to obtain a dual temperature domestic system. The mixing

valve provides tempered water to the xtures,

while the branch prior to the valve provides high temperature water for dishwashing, washing machines and other appliances.

2. Hot Water Boiler/Tankless Coils/Storage Tank - This application involves the use of several tankless coils piped in parallel, emptying into a large storage tank, and is typically used in larger DHW production

applications, such as hotel showers and laundries. See Figure 37b for recommended piping and wiring details for this type of application. The tempering valve and recirculation loop are advantageous in these applications, because they provide both high temperature and tempered domestic hot water to the system, eliminating the need to purge and waste water until it reaches the desired temperature. In the case where the boiler is used for domestic production only, and there is no space heating

involved, a destratication pump is utilized to provide ow within the boiler. This ow acts as a

means of preventing the hot water from stratifying

at the top of the boiler. Destratication pump ow

rates are given in the table in Figure 37b.

3. Hot Water Boiler/Indirect Water Heater - The use of indirect water heaters for domestic hot water generation is common and somewhat advantageous over tankless coils alone, since they also provide DHW storage. A tempering valve and recirculating pump are again recommended for a dual temperature system, to provide a constant temperature to the

xtures without waiting for cooler water to warm

up. Figure 37c shows a typical indirect heater piping application with no space heating. Indirect pump ow rates are calculated based on a 20°F DT.

NOTICE

DO NOT use the boiler circulator as an indirect domestic hot water system circulator.

4. Steam Boiler/Indirect Water Heater – Consult I=B=R Installation and Piping Guide No. 200. Use the Indirect Water Supply tapping, “R” (Special Order Only – see Figure 24) when connecting an Indirect Water Heater directly to the boiler.

NOTICE

When possible, domestic hot water production should utilize a dedicated boiler(s). This will allow the other boiler(s) to be shut down and isolated during the summer months. If the boiler load is shared between

heating and domestic hot water, then one needs to determine if a hot water priority is required. If a priority

is not selected, erratic domestic hot water production may result during the beginning and end of every

heating season. Conversely, a priority for domestic hot water production may cause a signicant heating zone activation delay, in an improperly balanced system. Parallel piping conversions may require isolation from the heating system to prevent system ow inuence on DHW performance. Consult a qualied system

heating professional to design for the proper application.

N. CONNECT TANKLESS HEATER PIPING as

shown in Figure 37a. See Table IV for Tankless Heater Ratings.

NOTICE

The following guidelines should be followed when piping the tankless heater:

1. Install Flow Regulator

If ow through the heater is greater than its rating,

the supply of adequate hot water may not be able to keep up with the demand. For this reason a FLOW REGULATOR matching the heater rating should be installed in the cold water line to the heater. Refer to Figure 37a for piping recommendations. Locate

the ow regulator below the inlet (cold water side)

of the heater and a minimum of 36” away from the inlet so that the regulator is not subjected to excess temperatures during “off” periods when it is possible for heat to be conducted back through the supply

line. The ow regulator will limit the ow of supply

water regardless of inlet pressure variations ranging from 20 to 125 psi.

2. Install Water Temperature Mixing Valve

WARNING

Install a mixing valve at the tankless heater outlet to avoid risk of burns or scalding due to

excessively hot water at xtures. Do not operate the boiler when equipped with a tankless heater

unless mixing valve is operating properly.

Refer to Figure 37a for piping recommendations.

Adjust and maintain the mixing valve in accordance with manufacturers instructions.

Installation of a mixing valve will also lengthen the

delivery of the available hot water by mixing some cold water with the hot. In addition, savings of hot

Figure 35: Recommended Piping for Combination

Heating & Cooling (Refrigeration) Systems

Water Boilers

water will be achieved since the user will not waste as much hot water while seeking desired water temperature. Higher temperature hot water required by dishwashers and automatic washers is possible by piping the hot water from the heater prior to entering the mixing valve. An electric hot water booster can also be used. The mixing valve should be “trapped” by installing it below the cold water inlet to heater to prevent lime formation in the valve.

3. Flushing of Heater

All water contains some sediment which settles

on the inside of the coil. Consequently, the heater should be periodically backwashed. This is accomplished by installing hose bibs as illustrated in Figure 37a and allowing water at city pressure to run into hose bib A, through the heater, and out hose bib B until the discharge is clear. The tees in which the hose bibs are located should be the same size as heater connections to minimize pressure drop.

4. Hard Water

A water analysis is necessary to determine the

hardness of your potable water. This is applicable to some city water and particularly to well water. An appropriate water softener should be installed based on the analysis and dealer’s recommendation.

This is not only benecial to the tankless heater but to piping and xtures plus the many other benets

derived from soft water.

Float Low Water Cut-Offs

CAUTION

Do not operate tankless heater with hard water. Tankless failure will result. Install water softener if hard water is present.

WARNING

If you do not follow these instructions

exactly, a re or explosion may result

causing property damage or personal injury. If any unusual or improper operation or site

conditions are observed, turn the boiler off and contact an experienced and skilled service agency.

Follow component manufacturer’s instructions. Component manufacturer’s instructions were provided with the boiler. Contact component manufacturer for replacement if instructions are missing. Do not install, start up, operate, maintain or service this boiler without reading and understanding all of the component instructions. Do not allow the boiler to operate with altered, disconnected or jumpered components. Only use replacement components identical to those originally supplied with the boiler and burner.

A. ALWAYS INSPECT INSTALLATION BEFORE

STARTING BURNER.

B. FILL HEATING SYSTEM WITH WATER.

Boiler must be cleaned and fully free of oil and dirt.

a. Close isolation valve in boiler supply piping.

b. Isolate all circuits by closing zone valves or

balancing valves.

c. Attach a hose to bib cock located just below

isolation valve in boiler supply piping.

(Note - Terminate hose in ve gallon bucket at a

suitable oor drain or outdoor area).

d. Starting with one circuit, open zone valve.

e. Open bib cock.

f. Open ll valve (Make-up water line should be

located directly above isolation valve in boiler supply piping).

g. Allow water to overow from bucket until

discharge from hose is bubble free for 30 seconds.

h. Open zone valve to the second zone to be

purged, then close the rst. Repeat this step until

all zones have been purged, but always have one zone open. At completion, open all zone valves.

i. Close bib cock, continue lling the system until

the pressure gauge registers normal system

design operating pressure. Close ll valve.

(Note - If make-up water line is equipped with pressure reducing valve, system will

automatically ll to normal system design

operating pressure. Leave globe valve open).

j. Open isolation valve in boiler supply piping.

k. Remove hose from bib cock.

CAUTION

Failure to clean the system will result in erratic water lines and surging, and other improper system operations.

CLEAN HEATING SYSTEM IF boiler water or

condensate return water is dirty or if erratic water lines or surging exist after a few days of boiler operation. Refer to Paragraph (F) for proper cleaning instructions for steam and water boilers.

1. STEAM BOILERS - Fill boiler to normal water line. As shown in Figure 1, the normal water line

is 41½” from the oor or bottom of casting. At

the start of each heating season and once or twice during the season try SAFETY VALVE to be sure it is in working condition. To do this, fasten wire or cord to lever of valve and pull lever — standing safe distance away from valve.

2. HOT WATER BOILERS - Fill entire Heating System with water and vent air from system. Use the following procedure on a Series Loop or Multizoned System to remove air from system when

lling:

DANGER

Do not operate boiler with pressure above maximum allowable working pressure listed on the Boiler Rating Label.

DO NOT draw water from boiler while in use. When adding water while boiler is in operation, do not open supply valve fully but add water slowly.

C. SET CONTROLS with burner service switch turned

“OFF”.

1. PRESS RESET BUTTON on primary control and release.

2. On STEAM BOILERS set cut-in pressure on L404A Pressuretrol for three (3) PSI and differential pressure for two (2) PSI. These pressures may be varied to suit individual requirements of installation.

3. On STEAM BOILERS WITH TANKLESS DOMESTIC WATER HEATERS, set boiler water temperature dial on low limit operating control at 190°F (max.). Set differential at 10°.

4. ON WATER BOILERS WITHOUT TANKLESS HEATERS, set high limit dial on L4006A at 210°F. This temperature may be varied to suit requirements of installation.

5. ON WATER BOILERS WITH TANKLESS HEATERS, set low limit operating control dial at 190°F and high limit dial 210°F. Operating control must be a minimum of 20° below high limit setting. Set differential at 25°.

CAUTION

Probe and oat type low water cutoff devices require annual inspection and maintenance.

4. CHECK OPERATING CONTROL on boiler equipped with tankless heaters. With burner off, draw hot water until burner starts, then turn off hot water and check burner shutdown.

D. ADJUST BURNER according to the Burner Manual.

1. FLAME FAILURE

The V9A boiler controls operate the burner

automatically. If for unknown reasons the burner

ceases to re and the reset button on the primary

control is tripped, the burner has experienced ignition failure. Before pressing the reset button, call your serviceman immediately.

WARNING

Do not attempt to start the burner when excess oil or gas has accumulated in the combustion chamber, when the unit is full of vapor, or when the combustion chamber is very hot.

E. TEST CONTROLS

WARNING

Before installation of the boiler is considered complete, the operation of the boiler controls should be checked, particularly the low water cutoff and the high limit control.

All controls must be checked prior to putting the boiler

in service.

1. CHECK OPERATING CONTROL OPERATION.

Raise and lower operating control setting as required

to start and stop burner.

2. CHECK OPERATION OF HIGH LIMIT CONTROL —

Jumper Operating Control Terminals. Allow burner

to operate until shutdown by limit. Installation is not considered complete until this check has been made. REMOVE JUMPER.

3. CHECK LOW WATER CUTOFF control with water level at normal water line (see Figure 1). Raise operating control setting to allow burner to operate. Open boiler drain to allow water level to drop to bottom of sight glass until burner operation is shut down by low water cutoff.

Close boiler drain and rell to normal water line.

Burner should automatically restart during ll.

RESET OPERATING CONTROL.

F. BOILER AND SYSTEM CLEANING - STEAM

BOILER

NOTICE

A qualied water treatment chemical specialist

should be consulted for recommendations regarding appropriate chemical compounds and concentrations which are compatible with local environmental regulations.

WARNING

Chemicals used in treating boiler water are toxic and/or harmful. Always use protective

clothing and equipment when working with/

near chemicals. Contact local authorities to determine if treated boiler water can be discharged into local waste water system.

1. Oil, greases & sediments which accumulate in a new boiler and piping must be removed in order to prevent an unsteady water line and carry over of the water into the supply main above boiler. Operate the boiler with steam in the entire system for a few days allowing the condensate to return to the boiler. If the condensate can temporarily be wasted, operate boiler only for the length of time it takes for condensate to run clear. If the latter cannot be achieved or if the condensate is returned to the boiler, boil out the boiler using the SURFACE BLOWOFF connection. See Figure 38a.

a. Drain boiler until water is just visible in gauge

glass. Run temporarily 1½” pipe line from the surface blowoff connection to an open drain or some other location where hot water may be discharged safely. Do not install valve in this line.

b. Add an appropriate amount of recommended

boilout compounds.

c. Start burner and operate sufciently to boil

the water without producing steam pressure. Boil for about 5 hours. Open boiler feed pipe

sufciently to permit a steady trickle of water

from the surface blowoff pipe. Continue this

slow boiling and trickle of overow for several hours until the water coming from the overow

is clear.

d. Stop burner and drain boiler in a manner and to

a location that hot water can be discharged with safety.

e. Rell boiler to normal water line. If water in

gauge glass does not appear to be clear, repeat steps (a. thru e.), and boil out the boiler for a longer time.

2. Low pressure steam boilers such as the V9A Series should be maintained with appropriate water treatment compounds. After cleaning process has been completed, add water treatment compounds

as recommended by your local qualied water

treatment company.

3. Remove temporary surface blowoff piping and replug tapping. Boil or bring water temperature to 180°F promptly in order to drive off the dissolved gases in the fresh water.

4. If unsteady water line, foaming or priming persist, install gate valve in Hartford Loop and drain valves in return main and at boiler and proceed as follows:

a. Connect hoses from drain cocks to oor drain.

Close gate valve in Hartford Loop and open drain valve in return main. Fill boiler to normal water level, turn on burner and operate boiler at this water level for at least 30 minutes after the condensate begins to run hot, then turn off burner.

Close all radiator valves. Remove all supply

main air valves and plug the openings in supply main.

b. Draw about 5 gallons of hot water from boiler

into a container and dissolve into it appropriate amount of a recommended boilout compound. Remove surface blowoff plug and pour this solution into boiler, then reinstall plug.

c. Turn on burner and keep operating while feeding

water to boiler slowly. This will raise water level in boiler slowly so that water will be boiling hot and will rise slowly into supply main and back

through return main, owing from drain hose

at about 180°F. Continue until water runs clear from drain hose for at least 30 minutes.

d. Stop feeding water to boiler but continue

operating burner until excess water in boiler

ows out through supply main and water lowers

(by steaming) until it reaches normal level in boiler. Turn off burner. Drain boiler. Open all radiator valves. Reinstall all supply main air valves. Open gate valve in Hartford Loop.

e. When boiler has cooled down sufciently (crown

sheet of sections are not too hot to touch), close the drain cocks at boiler and in return main and feed water slowly up to normal level in boiler. Turn on burner and allow boiler to steam for 10 minutes then turn off burner. Draw off one

quart of water from bottom gauge glass tting

and discard. Draw off another quart sample and

if this sample is not clear, repeat the cycle of

draining the boiler and return main and relling

the boiler until sample is clear.

f. If the boiler water becomes dirty again at a later

date due to additional sediment loosened up in the piping, close gate valve in Hartford Loop, open drain valve in return main, turn on burner

and allow condensate to ow to drain until it has

run clear for at least 30 minutes while feeding water to boiler so as to maintain normal water level. Turn off burner, drain boiler, open gate valve in Hartford Loop, then repeat step (1) above.

5. Make pH or Alkalinity Test.

After boiler and system have been cleaned and

relled as previously described, test the pH of the

water in the system. This can easily be done by drawing a small sample of boiler water and testing hydrion paper which is used in the same manner

as litmus paper, except it gives specic readings.

A color chart on the side of the small hydrion dispenser gives the reading in pH. Hydrion paper is inexpensive and obtainable from any chemical supply house or through your local druggist. The pH should be higher than 7, but lower than 11. Add some appropriate water treatment chemicals, if

necessary to bring the pH within the specied range.

6. Boiler is now ready to be put into service.

G. BOILER AND SYSTEM CLEANING - WATER

BOILERS

1. Filling of Boiler and System --- General --- In a hot water heating system, the boiler and entire system (other than the expansion tank) must be full of water for satisfactory operation. Water should be added to the system until the boiler pressure gauge registers normal system design operating pressure. To insure that the system is full, water should come out of all air vents when opened.

2. Boiling Out of Boiler and System. The oil and grease which accumulate in a new hot water boiler can be washed out in the following manner.

a. Remove safety relief valve using extreme care to

avoid damaging it.

b. Add an appropriate amount of recommended

boilout compound.

c. Reinstall safety relief valve.

d. Fill the entire system with water.

e. Start ring the boiler.

f. Circulate the water through the entire system.

g. Vent the system, including the radiation.

h. Allow boiler water to reach operating

temperature, if possible.

i. Continue to circulate the water for a few hours.

j. Stop ring the boiler.

k. Drain the system in a manner and to a location

that hot water can be discharged with safety.

l. Remove plugs from all available returns and

wash the water side of the boiler as thoroughly as possible, using a high-pressure water stream.

m. Rell the system with fresh water.

3. Add appropriate boiler water treatment compounds

as recommended by your local qualied water

treatment company.

4. Make pH or Alkalinity Test.

After boiler and system have been cleaned and

relled as previously described, test the pH of the

water in the system. This can easily be done by drawing a small sample of boiler water and testing with hydrion paper which is used in the same

manner as litmus paper, except it gives specic

readings. A color chart on the side of the small hydrion dispenser gives the reading in pH. Hydrion paper is inexpensive and obtainable from any chemical supply house or thru your local druggist. The pH should be higher than 7 but lower than 11. Add some appropriate water treatment chemicals, if

necessary to bring the pH within the specied range.

With this lower level of protection, care must be exercised to eliminate all of the free oxygen in the system.

5. Boiler is now ready to be put into service.

IMPORTANT

IF, DURING NORMAL OPERATION, IT IS NECESSARY TO ADD MORE WATER PER MONTH THAN INDICATED BELOW, CONSULT A QUALIFIED SERVICE TECHNICIAN TO CHECK YOUR SYSTEM FOR LEAKS.

water are dissolved minerals and oxygen. When the fresh, cool make-up water is heated in the boiler the minerals fall out as sediment and the oxygen escapes as a gas. Both can result in reduced boiler life. The accumulation of sediment can eventually isolate the water from contacting the cast iron. When this happens the cast iron in that area gets extremely hot and eventually cracks. The presence of free oxygen in the boiler creates a corrosive atmosphere which, if the concentration becomes high enough, can corrode the cast iron through from the inside. Since neither of these failure types are the result of a casting defect, the warranty does not apply. The maintenance of system integrity is the best method to prevent these types of failure.

I. OXYGEN CORROSION:

WARNING

Oxygen contamination of the boiler water will cause corrosion of iron and steel boiler components, and can lead to boiler failure. Burnham’s standard warranty does not cover problems caused by oxygen contamination of boiler water or scale (lime) build-up caused by

frequent addition of water.

There are many possible causes of oxygen

contamination such as:

a. Addition of excessive make-up water as a result

of system leaks.

b. Absorption through open tanks and ttings.

c. Oxygen permeable materials in the distribution

system.

In order to insure long product life, oxygen sources

must be eliminated. This can be accomplished by taking the following measures:

a. Repairing system leaks to eliminate the need for

addition of make-up water.

b. Eliminating open tanks from the system.

c. Eliminating and/or repairing ttings which allow

oxygen absorption.

d. Use of non-permeable materials in the

distribution system.

e. Consult your local water treatment specialist for

specic recommendations.

and remove the plates. The insulation should be removed with the plates taking care not to damage the insulation.

c. Using a 1¼” diameter wire or bre bristle brush

(36” handle) clean the ueways. Start at the top of each ueway opening and work down the pin

rows using two or three horizontal strokes per row for best results.

3. CLEAN TOP OF BOILER SECTIONS

Remove the jacket top panel. Remove the top ue

canopy cover or outlet assembly. Use a ashlight to inspect the upper portion of the ueways and top of

castings for soot and debris. Heavy accumulations over 1/16” thick must be removed. Remove the canopy being careful not to damage the cerafelt

strips. Brush and vacuum the upper ueways and

tops of castings.

4. CLEAN THE FIREBOX

5. REASSEMBLE BOILER

CAUTION

Do not start the burner unless canopy, smokepipe,

burner mounting plate and all ue plates are

secured in place.

a. If removed, install the canopy taking care to

align the cerafelt strips. If strips are damaged replace as needed.

b. Reinstall burner mounting plate to front section

making sure 3/16” diameter rope gasket is in place and forms gas tight seal. If gasket is damaged, replace.

c. Bolt burner to burner mounting plate. Inspect

gasket to assure adequate seal. Replace if damaged. Connect oil line(s) and/or gas line(s).

d. Reinstall ue plates making sure gasket on each

plate is in place and forms gas tight seal. If damaged, all edges of the cleanout plates should be sealed with Silastic sealant when reinstalled until insulation can be replaced.

e. If removed, reinstall jacket top.

f. Reinstall left side panels.

g. Reinstall smokepipe.

C. MAINTENANCE OF LOW WATER CUTOFF

DEVICES.

NOTICE

Probe and oat type low water cutoff devices require annual inspection and maintenance.

1. PROBE TYPE LOW WATER CUTOFF

Although these devices are solid state in their

operation, the probe is exposed to possible contamination in the boiler water and subject to fouling.

It is important to physically remove the probe from

the boiler tapping annually and inspect that probe for accumulation of scale or sediment.

Follow these steps to inspect, clean and/or replace

the probe:

a. Turn off electric service to the boiler.

b. Drain boiler water to a level below the tapping

for the probe.

DANGER

Assure that the boiler is at zero pressure before removing the LWCO probe. Do not rely on the pressure gauge to indicate that the boiler is at zero pressure. Open the safety valve to relieve all internal pressure prior to proceeding. Safety valve discharge piping must be piped such that the potential for burns is eliminated.

c. Disconnect wiring connections between the low

water cutoff control and the probe.

d. Dismount the low water cutoff control from the

probe.

e. Unscrew the probe from the boiler tapping.

f. Inspect that portion of the probe that is exposed

to the boiler water for a scale or sediment buildup.

g. Light deposits may be removed by wiping the

probe with a damp cloth. Wiping the probe with a cloth soaked in vinegar will remove more tenacious lime deposits. The most stubborn deposits may be removed from the probe by using a diluted amount (three 3 parts of water to one (1) part) of phosphoric acid (H2PO4).

WARNING

Exercise caution when handling phosphoric acid and follow the instructions on container label.

Always use protective clothing and equipment

when working with/near chemicals.

h. Wire brushing of the probe is not recommended

as the soft platinum guard ring sandwiched between the ceramic insulators may be damaged. Care must be taken not to damage this ring in any way or the useful life of the probe may be shortened.

i. Clean the pipe threads of the probe to remove

old, hardened pipe dope and other foreign matter.

j. Apply a moderate amount of good quality pipe

dope to the pipe threads on the probe. Leaving the two end threads bare. Do not use PTFE

(Teon) tape.

k. Screw the probe into the boiler tapping.

l. Mount the low water cutoff control on the probe.

m. Reconnect the control to probe wiring.

n. Fill the boiler to its normal waterline.

o. Add boiler water treatment compound as needed.

p. Restore electric service to the boiler.

q. Fire burner to bring the water in the boiler to a

boil to drive off free oxygen.

r. BEFORE RETURNING BOILER TO

SERVICE Follow the low water cutoff checkout procedure in Section IV, Paragraph E, Step 3.

2. FLOAT TYPE LOW WATER CUTOFF

During the heating season, if an external low water

cutoff is on the boiler, the blow off valve should be opened once a month (use greater frequency

where conditions warrant), to ush out the sediment

chamber so the device will be free to function properly.

Low water cutoffs and water feeders should be

dismantled annually by qualied personnel, to the

extent necessary to insure freedom from obstructions

and proper functioning of the working parts. Inspect connecting lines to boiler for accumulation of mud, scale, etc., and clean as required. Examine all visible wiring for brittle or worn insulation and make sure electrical contacts are clean and that they function properly. Give special attention to solder

joints on bellows and oat when this type of control is used. Check oat for evidence of collapse and

check mercury bulb (where applicable) for mercury separation or discoloration. DO NOT ATTEMPT TO REPAIR MECHANISMS IN THE FIELD. Complete replacement mechanisms, including necessary gaskets and installation instructions, are available from the manufacturer.

D. CHECK BURNER AND CONTROLS at least

once a year. See Section IV - Operating Instructions, Paragraph E for control checks. See Burner Manual for burner tests and adjustments.

E. LUBRICATE BOILER COMPONENTS according

to manufacturer’s instructions. Generally, this involves the oil burner and circulator. This includes the type of lubricant to use, frequency of lubrication, and points to lubricate.

F. GENERAL MAINTENANCE CONSIDERATIONS

1. Keep radiators and convectors clean.

2. If a hot water radiator is hot at the bottom but not at the top, it indicates that air has accumulated inside and should be vented. To vent radiator, hold small cup under air vent (located near top of radiator), open vent until water escapes and then close.

3. If much water is added to system, it is advisable to heat system to a high temperature and vent again.

This will make less venting necessary during the winter.

4. Where an expansion tank is used, make sure that neither the tank nor its drain pipe is exposed to freezing temperatures. Never place valves in piping leading to or from expansion tank.

5. Boiler and system cleaning will help assure trouble free operation. See Section IV - Operating Instructions, Paragraphs F or G for procedure.

G. ATTENTION TO BOILER WHILE NOT IN

OPERATION

WARNING

If boiler is not used during winter time, it must be fully drained to prevent freeze damage.

1. Spray inside surfaces with light lubricating or crankcase oil using gun with extended stem so as to reach all corners.

2. With steam boilers, at end of season add sufcient water to ll boiler to top of water column and leave

it that way until fall when water should be drained again to proper level. If at this time boiler water is

dirty, drain water, ush out boiler, and rell with

clean water to prescribed water level.

3. Always keep the manual fuel supply valve shut off when the burner is shut down for an extended period of time.

4. To recondition the heating system in the fall season after a prolonged shut down, follow the instructions outlined in Section IV - Operating Instructions, Paragraphs B through G.
