This boiler must be properly vented.

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 system 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 safety devices 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 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.

Boiler 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.

Failure to follow all instructions in the proper order can cause personal injury or death. Read all instructions, including all those contained in component manufacturers manuals which are provided with the boiler before installing, starting up, operating, maintaining or servicing.

Keep boiler area clear and free from combustible materials, gasoline and other ammable vapors or liquids.

All cover plates, enclosures and guards must be in place at all times.

This product must be installed by a licensed plumber or gas tter when installed within the Commonwealth

of Massachusetts.

I. Pre-Installation

WARNING

Carefully read all instructions before installing boiler. Failure to follow all instructions in proper order can cause personal injury or death.

1. Determine volume of space (boiler room). Rooms communicating directly with space (through openings not furnished with doors) are considered part of space.

Volume [ft³] = Length [ft] x Width [ft] x Height [ft]

A. Installation must conform to the requirements of the

authority having jurisdiction. In the absence of such requirements, installation must conform to the National Fuel Gas Code, NFPA 54/ANSI Z223.1, and/or CAN/CSA B149 Installation Codes. Where required by the authority having jurisdiction, the installation must conform to the Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1.

B. The boiler is not design certied for installation on

combustible ooring. The boiler must not be installed

on carpeting.

C. Provide clearance between boiler jacket and

combustible material in accordance with local re

ordinance. Refer to page 4 of this manual for minimum listed clearance from combustible material.

D. Install on level oor. For basement installation provide

concrete base if oor is not perfectly level or if water may be encountered on oor around boiler. Floor

must be able to support weight of boiler, water and all additional system components.

E. Protect gas ignition system components from water

(dripping, spraying, rain, etc.) during boiler operation and service (circulator replacement, condensate trap service, control replacement, etc.).

F. Provide combustion and ventilation air in accordance

with applicable provisions of local building codes or: USA - National Fuel Gas Code, NFPA 54/ ANSI Z223.1, Section 5.3, Air for Combustion and Ventilation; Canada - Natural Gas Installation Code, CAN/CSA - B149.1, or Propane Installation Code, CAN/CSA - B.149.2, Part 5, Venting Systems and Air Supply for Appliances.

WARNING

Adequate combustion and ventilation air must be

provided to assure proper combustion.

The following guideline is based on the National Fuel

Gas Code, NFPA 54/ANSI Z223.1.

2. Determine Total Input of all appliances in space. Round result to nearest 1,000 Btu per hour (Btuh).

3. Determine type of space. Divide Volume by Total Input.

a. If result is greater than or equal to 50 ft³ per

1,000 Btuh, space is considered an unconned space.

b. If result is less than 50 ft³ per 1,000 Btuh, space

is considered a conned space.

4. Determine building type. A building of unusually tight construction has the following characteristics:

a. Walls and ceiling exposed to outside atmosphere

have a continuous water vapor retarder with a rating of 1 perm or less with openings gasketed and sealed, and;

b. Weather-stripping has been added on openable

windows and doors, and;

c. Caulking or sealants applied in joints around

window and door frames, between sole

plates and oors, between wall-ceiling joints,

between wall panels, at plumbing and electrical penetrations, and at other openings.

5. For boiler located in an unconned space in a building of other than unusually tight construction, adequate combustion and ventilation air is normally

provided by fresh air inltration through cracks

around windows and doors.

NOTICE

Boilers operated with sealed combustion are exempt from needing provisions for combustion air from the room, provided air intake piping is installed per code and the instructions in this manual.

6. For boiler located within unconned space in building of unusually tight construction or within conned space, provide outdoor air through two

permanent openings which communicate directly or by duct with the outdoors or spaces (crawl or attic) freely communicating with the outdoors. Locate one opening within 12 inches of top of space. Locate remaining opening within 12 inches of bottom of space. Minimum dimension of air opening is 3 inches. Size each opening per the following:

a. Direct communication with outdoors. Minimum

free area of 1 square inch per 4,000 Btu per hour input of all equipment in space.

b. Vertical ducts. Minimum free area of 1 square

inch per 4,000 Btu per hour input of all equipment in space. Duct cross-sectional area shall be same as opening free area.

c. Horizontal ducts. Minimum free area of 1

square inch per 2,000 Btu per hour input of all equipment in space. Duct cross-sectional area shall be same as opening free area.

Alternate method for boiler located within conned

space. Use indoor air if two permanent openings communicate directly with additional space(s) of

sufcient volume such that combined volume of all spaces meet criteria for unconned space. Size each

opening for minimum free area of 1 square inch per 1,000 Btu per hour input of all equipment in spaces, but not less than 100 square inches.

7. Ventilation Duct Louvers and Grilles. Equip outside openings with louvers to prevent entrance of rain and snow, and screens to prevent entrance of insects

and rodents. Louvers and grilles must be xed in

open position or interlocked with equipment to open automatically before burner operation. Screens must not be smaller than ¼ inch mesh.

Consider the blocking effect of louvers, grilles and

screens when calculating the opening size to provide the required free area. If free area of louver or grille is not known, assume wood louvers have 20-25 percent free area and metal louvers and grilles have 60-75 percent free area.

DANGER

Do not install boiler where gasoline or other

ammable vapors or liquids, or sources of

hydrocarbons (i.e. bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.) are used or stored.

NOTICE

Due to the low water content of the boiler, incorrect sizing of the boiler with regard to the heating system load will result in excessive boiler cycling and accelerated component failure. Thermal Solutions DOES NOT warrant failures caused by incorrectly sized boiler applications. DO NOT oversize the boiler to the system. Modular boilers greatly reduce the likelihood of boiler oversizing.

II. Unpack the Boiler

NOTICE

Boiler crate is equipped with a tip and tell label. If

label indicates boiler has been tipped over during shipping, remove crate and inspect before trucker leaves.

CAUTION

Do not drop boiler. Do not bump boiler jacket

against oor.

A. Move boiler to approximate installed position.

B. Remove all crate fasteners.

C. Open outside container and remove all inside protective

spacers and bracing.

D. Remove all boiler hold-down fasteners.

WARNING

Installation of this boiler should be undertaken only by trained and skilled personnel from a

qualied service agency.

E. Remove unit from shipping skid (if provided).

1. Tilt the boiler to one side and slide a small roller

under the raised base.

2. Tilt the boiler to the other side and slide another roller under the base.

3. Place a larger pipe roller on oor behind the skid.

4. Roll the boiler forward or backward off the skid and onto the pipe roller.

F. Move boiler to its permanent location.

III. Installation

NOTICE

Although details for indoor installation may be rarely applicable, Thermal Solutions recognizes that instances may exist where such details are

required and have been included within this

manual for this purpose.

WARNING

Do not use vent dampers or barometric dampers with positive pressure vent systems.

b. Direct vent applications: For direct vent (ducted

combustion air) installations, the maximum vent length is 50 equivalent feet. The vent length is equal to the total length of straight pipe plus the equivalent length of

vent ttings.

d. Install a condensate drain to collect any condensate that

may form in the lined chimney/vertical vent.

e. Install a double acting barometric damper with integral

ue spillage interlock.

f. The chimney/vertical vent and ue connector must be

sized and congured to provide a minimum - 0.04 inch w.c. pressure (draft) at the boiler ue outlet.

g. The chimney must be protected from down drafts, rain

and debris by using a chimney cap or star.

4. General Guidelines

a. This boiler has been certied with AL29-4C® venting.

Select a vent material that is approved for use with

condensing ue gasses.

b. Install vent system before installing air intake, water,

gas or electrical connections.

c. For instances where the vent system manufacturer’s

instructions do not make a specication, refer to the

below points.

i. Make sure pipe and ttings are clean by swabbing

with alcohol. Use Dow Corning 736 or 732 RTV, Polybar #500 RTV or Sil-bond 4500 or 6500 to seal vent pipe.

c. Non-direct vent applications: For non-direct vent

installations (those without ducted combustion air), design the vent system so that the pressure measured at the outlet of the boiler is between 0”w.c. and 0.3”w.c. at

high re.

d. For sidewall venting, slope pipe toward vent

termination, if possible.

e. See Figures 2, 3 and 4 for examples of positive pressure

venting arrangements.

3. Negative Pressure (Conventional) Venting

Requirements

This section outlines requirements for conventional

venting installations, where a negative pressure at

the boiler ue outlet is achieved by means of natural

convection through a vertical length of vent pipe or lined chimney.

a. Refer to Figure 5 for an example of a typical

conventional venting arrangement.

b. A lined chimney or vertical length of vent pipe may be

used. Chimney lining must be acceptable for use with

condensing ue gas.

ii. Refer to the appropriate drawings in this section

of this manual to determine common acceptable

congurations of venting system.

Figure 5: Typical Negative Pressure (Conventional) Venting

B. COMBUSTION AIR - See Figures 6 and 7.

1. The boiler may be operated with inside or outside

air.

2. Refer to air intake piping drawings in this section

for proper outside air installation details.

3. Combustion air conduit can be galvanized smoke

pipe, PVC, CPVC, or exible aluminum conduit.

4. The maximum air intake pipe length is fty (50)

equivalent feet. Air intake pipe length is equal to the total length of straight pipe plus the equivalent

length of ttings. Consult intake pipe manufacturer for equivalent length of ttings and pipe.

5. Consult air intake pipe manufacturer's instructions

for proper method of sealing vent pipe sections

and ttings. Do not use other adhesives or sealants

except as expressly permitted by the vent pipe manufacturer's instructions.

WARNING

Do not reduce size of air intake pipe.

Read, understand and follow combustion air instruction restrictions contained in the PreInstallation instructions of this manual.

6. Air intake termination must be located at least

twelve (12) inches above grade plus the expected snow accumulation.

7. Boiler may be installed with vertical venting and sidewall intake air or visa versa.

8. The horizontal air intake pipe must be adequately

supported with straps or supports no less than ve

(5) feet apart. The completed air intake pipe system must be rigid and able to withstand impacts without collapse.

CAUTION

Dirty, contaminated or dusty air used for combustion will decrease the useful life of

the boiler air lter. Use outside air if inside air quality is questionable. Use outside air if

the boiler is installed in manufacturing plants, laundries, dry cleaners or other locations with heavy particulates in the air.

WARNING

Do not locate air intake where petroleum distillates, CFCs, detergents, volatile vapors or any other chemicals are present. Severe boiler corrosion and failure will result. Thermal Solutions does not warrant failures caused by contaminated air.

Do not locate air intake termination where natural convection or wind conditions may cause the boiler exhaust gases to be drawn into the air intake.

C. WATER TREATMENT

The quality of water used in the heating system is essential for the successful operation and longevity of the system components. A successful water treatment plan will help to

maintain efciency, reduce the regularity of repair and/or

replacement, and extend the working life of the boiler and other system equipment. If left untreated, poor water quality could cause a number of problems including, but not limited to, oxidation, scaling, corrosion, and fouling. See Table 1 for examples of typical chemical agents found in untreated water along with their potential effects.

CAUTION

The water shall have a maximum water hardness of 8.5 grains or 150 ppm. The recommended pH range is 8.8 to 9.2. However, other aspects

of water quality can affect boiler operation and longevity. A qualied water treatment expert

should be consulted to develop a complete water treatment plan.

Oxygen contamination of boiler water will cause corrosion of iron and steel boiler components, and can lead to boiler failure. Thermal Solutions Standard Warranty does not cover problems caused by oxygen contamination of boiler water.

Proper water treatment and boiler maintenance

is required to avoid scale build-up on the inside

of the boiler. Thermal Solutions Standard Warranty does not cover problems caused by scale build-up.

When using Glycol products, all Glycol

manufacturers' requirements, including rust

inhibitors, must be adhered. Max 50% Glycol.

Since the condition of water varies from location to

location, it is impossible to prescribe a one-size-ts-all

treatment plan for the system water. In order to develop an effective water treatment plan, it will be necessary to gain knowledge of the impurities dissolved in the water.

Once all the impurities are identied, the proper treatment

plan can be established. Therefore, it will be essential to

obtain the expertise of a qualied industrial water treatment

professional for establishing a treatment plan.

In addition, a periodic testing/sampling plan should be developed. The intent of the plan should be to: (1) ensure the protection of the boiler and system equipment, (2) prevent an unforeseen system failure, (3) provide information for use in addressing the water quality, and (4)

to conrm the proper concentration of chemicals in use.

D. WATER PIPING AND TRIM

CAUTION

Failure to properly pipe boiler may result in improper operation and damage to boiler or structure.

All piping either new or existing must be cleaned with a tri sodium phosphate (TSP) solution to remove mill scale and oils from the system. Failure to do so could result in premature failure of the heat exchanger (not covered by Thermal Solutions Standard Warranty).

On an existing or retrot system, a lter or

strainer must be installed on the system return prior to the boilers.

Return water temperature below 120°F will cause

ue gas condensation inside the boiler. Flue gas

condensate can lead to boiler failure. Thermal Solutions Standard Warranty does not cover

problems caused by ue gas condensation.

Supply and return water temperature differences

greater than 40°F at high re can lead to boiler

failure. Thermal Solutions Standard Warranty does not cover problems caused by temperature

differences greater than 40°F at high re.

1. Design and install boiler and system piping to prevent oxygen contamination of boiler water and frequent water additions.

a. There are many possible causes of oxygen

contamination such as:

i. Addition of excessive make-up water

as a result of system leaks.

ii. Absorption through open tanks and ttings.

iii. Oxygen permeable materials in the

distribution system.

b. In order to insure long product life, oxygen

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

i. Repairing system leaks to eliminate the need

for addition of make-up water.

ii. Eliminating and/or repairing ttings which

allow oxygen absorption.

iii. Using of non-permeable materials in the

distribution system.

iv. Isolating the boiler from the system water by

installing a heat exchanger.

v. Using properly designed and operating air

elimination devices in water piping.

c. Maintain ½" minimum distance between water

piping and combustible material.

d. Consult Thermal Solutions for unusual system

requirements.

CAUTION

Support weight of system piping adequately.

e. Design and install system piping to prevent

return water temperatures below 120°F. Refer

to Table 2 for boiler ow and pressure drop

requirements.

3. Remove protective cap from boiler drain line located in the rear of the boiler .

4. Install drain valve in the boiler drain line at bottom rear of the boiler.

5. If this boiler is used in connection with refrigeration systems, the boiler must be installed so that the chilled medium is piped in parallel with the boiler using appropriate valves to prevent the chilled medium from entering the boiler. Also consult I=B=R Installation and Piping Guides. If this boiler is connected to heating coils located in air handling units where they may be exposed to refrigerated air,

the boiler piping must be equipped with ow control

valves to prevent gravity circulation of boiler water during operation of the cooling system.

6. Install optional low water cut-off in system piping above the boiler, if not shipped with boiler.

7. Install an air eliminating device to remove air from the system.

2. Connect system supply and return piping to boiler.

a. Refer to Figure 8.

b. Consult I=B=R Installation and Piping Guides.

WARNING

E. GAS PIPING

Failure to operate the unit with the proper water

ow rate can lead to appliance failure. Always verify proper water ow switch operation so that the unit stops operating if improper water ow is

present.

Safety relief valve discharge piping must be piped such that the potential of severe burns is eliminated. DO NOT pipe in any area where freezing could occur. DO NOT install any shutoff valves, plugs or caps. Consult Local Codes for proper discharge piping arrangement.

If a high head system pump is installed, ensure that the boiler relief valve and system piping are capable of operating properly at the combined

pressure of the system ll pressure plus the

pump static head pressure.

Do not install valves, plugs or caps in safety relief valve piping.

Safety relief valve piping must be terminated such that in the event the safety relief valve opens, the discharge will not cause personal injury or damage.

Do not operate the boiler with ow rates in excess of the maximum ow rates listed in Table

2. Tube erosion and pitting will occur. Thermal Solutions Standard Warranty does not cover

problems caused by excessive water ow rates.

8. There must be a minimum of ve pipe diameters of straight horizontal run downstream of the ow switch. Otherwise, premature failure of ow switch paddle may occur. See ow switch instruction

manual included with boiler.

9. If the boiler is installed in a closed water supply

system, such as one having a back ow preventer in

the cold water supply line, means shall be provided to control thermal expansion. Contact the water supplier or local plumbing inspector on how best to control this situation.

10. A pressure relief valve is supplied with each boiler. No valve is to be placed between the relief valve and appliance.

a. Pipe the safety relief discharge to a suitable place

for disposal when relief occurs. b. Do not install reducing couplings or other

restrictive devices in the safety relief discharge line.

c. The safety relief discharge line must allow for

complete drainage of both the valve and line.

11. If the relief valve discharges periodically, this may be due to thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to correct this situation. DO NOT PLUG THE RELIEF VALVE.

WARNING

Failure to properly pipe gas supply to boiler may result in improper operation and damage to the boiler or structure. Always assure gas piping is absolutely leak free and of the proper size and type for the connected load.

An Additional gas pressure regulator may be needed. Consult gas supplier.

1. Size gas piping. Design system to provide adequate gas supply to boiler. Consider these factors.

a. Allowable pressure drop from point of delivery

to boiler. Refer to Table 3 for minimum and maximum boiler gas train inlet pressure at steady state. If gas supply pressure is higher than

maximum as listed in Table 3, an additional eld

supplied pressure regulator will be required.

b. If a lower minimum gas pressure is needed,

the low gas pressure build can be used. The minimum gas pressure on all the low gas pressure builds is 4.0 in. w.c. Consult factory if this option is desired. This option is not available on the EVO-500.

c. Maximum gas demand. Table 7 lists boiler input

rate. Also consider existing and expected future gas utilization equipment (i.e., water heater, cooking equipment).

d. Length of piping and number of ttings. Refer

to Table 4 for maximum capacity of schedule 40 pipe. Table 6 lists equivalent pipe length for

standard ttings.

i. Specic gravity of gas correction factor,

to be applied to the value found in Table 4, can be found in Table 5.

ii. For gas piping material other than schedule

40 pipe, refer to the National fuel gas code, NFPA 54/ANSI Z223.1 and/or CAN/GCA B149 Installation codes.

2. If step down regulator is required, it must be used in conjunction with the factory supplied regulator and be located as far away from the boiler as possible to prevent nuisance shutdowns. The minimum and maximum inlet gas pressure must not exceed the

value specied in Table 3.

3. Install eld supplied sediment trap, ground-joint

union and manual non-displacable shut-off valve upstream of factory supplied shut-off valve outside the boiler jacket. Use methods and materials in accordance with Local Codes and requirements of gas supplier. In absence of such requirements, follow National Fuel Gas Code, NFPA 54/ANSI Z223.1 and/or CAN/CSA B149 Installation Codes.

4. Use thread joint compound resistant to the action of

liqueed petroleum gas.

WARNING

Failure to use proper thread compounds on all

gas connectors may result in leaks of ammable

gas.

5. All above ground gas piping upstream from eld

supplied manual gas valve must be electrically continuous and bonded to a grounding electrode. Do not use gas piping as grounding electrode. Refer to National Electrical Code, ANSI/NFPA 70 and /or CSA C22.1 Electrical Codes.

WARNING

Gas supply to boiler and system must be absolutely shut off prior to installing or servicing boiler gas piping.

WARNING

boiler from gas supply piping by closing the boiler's individual manual shutoff valve.

b. Locate leaks using approved combustible

gas detector, soap and water, or similar

nonammable solution.

DANGER

Do not use matches, candles, open ames or

other ignition source to check for leaks.

Use an additional gas pressure regulator where the gas pressure is greater than 5 psig. Using one additional regulator for multiple boilers may result in unsafe boiler operation. The additional regulator must be able to properly

regulate gas pressure ow at the lowest input

of a single boiler. If the regulator cannot do this,

two or more additional regulators are required.

Consult regulator manufacturer's instructions for

minimum gas ow rate.

6. Pressure test. The boiler and its gas connection must be leak tested before placing boiler in operation.

a. Protect boiler gas control valve. For all testing

over ½ psig, boiler and its individual shutoff valve must be disconnected from gas supply piping. For testing at ½ psig or less, isolate

G. MODULAR SYSTEMS

1. General Guidelines

a. Read and follow all venting, combustion

air, water piping, gas piping and electrical instructions contained in this manual unless otherwise instructed in this section.

b. Design and installation of modular systems

should only be undertaken by skilled and knowledgeable engineers and contractors.

c. Consult Local Building Codes, National Fuel

Gas Code, or NFPA 54/ANSI Z223.1 for restrictions and instructions for modular boilers.

d. Refer to the Pre-Installation section for further

warnings, cautions, notices and instructions.

2. Module Sizing

Consult factory for recommended number and size

of boilers for a given input.

3. Venting

This section outlines venting requirements for

multiple boiler installations and should be used in

addition to the “VENTING” section earlier in this

manual.

a. Positive Pressure (Sidewall and Vertical) Venting

i. Positive pressure vent systems cannot be

manifolded together.

ii. Positive pressure systems can be piped

individually through a common vertical or horizontal chase provided minimum clearances to combustible materials are maintained.

iii. Positive pressure systems can be piped

individually through a common vertical chase so that a single roof penetration can be made. Each vent termination must be one (1) foot from all other terminations.

WARNING

DO NOT manifold vent components of multiple boilers without converting to a negative pressure venting arrangement.

b. Negative Pressure (Conventional) Venting

i. Refer to Figure 10 for an example of a

typical conventional venting arrangement for modular boilers.

ii. Refer to National Fuel Gas Code to

determine required chimney diameter and common venting diameter. Note that combined input, lateral length and chimney height affect vent diameter.

iii. Install a double acting barometric damper

with integral ue spillage interlock (as

shown in Figure 10).

iv. Locate boiler(s) with lowest input closest to

chimney/vertical common vent.

v. Chimney lining must be acceptable for use

with condensing ue gases.

vi. Install a condensate drain to collect any

condensate that may form in the lined chimney or vertical common vent (refer to

gure 10).

CAUTION

Installing multiple vent terminations close together promotes frost build up on buildings. To minimize this possibility, extend the distance from the building to the end of the vent termination and increase the horizontal distance between vent terminations.

4. Air Intake Piping

a. Consult intake pipe manufacturer for common

air intake pipe sizing.

b. Refer to Figures 11 and 12 for common air intake

guidelines for modular boilers.

c. Individual air intake pipes may be used in lieu of

common air intake piping.

d. Common air intake straight lengths and ttings

should be assumed to have the equivalent length the same as an individual air intake pipe, used for a given boiler intake pipe diameter.

e. Position horizontal air intake termination center

line below horizontal vent termination's center line.

f. Vertical air intake pipe must terminate at least

two (2) feet above the closest portion of the roof.

6. Gas Piping

a. Refer to National Fuel Gas Code, Local Codes

and Tables 2 through 7 for gas pipe sizing.

b. Refer to Gas Piping section for further warnings,

cautions, notices and instructions.

NOTICE

The pressure drop given in Table 1 is for the boiler only. The pressure drop of each system

tting and component must be added to the

boiler pressure drop to determine the system

pressure head requirement. See Table 6 for tting and component equivalent lengths.

g. Refer to the Combustion Air section for further

warnings, cautions, notices and instructions.

5. Water Piping

a. Refer to Figures 13 thru 18 for typical water

piping for modular boilers.

b. Installing a low water cut-off in the system

piping is highly recommended and may be required by Code, if not factory mounted on boiler.

c. Refer to Table 1 for pressure drop and ow

requirements for each boiler.

d. Consult I=B=R Installation and Piping Guide.

e. Maintain ½" minimum distance between water

piping and combustible material.

f. Refer to Water Piping and Trim section

for further warnings, cautions, notices and instructions.

7. Electrical

a. Each boiler must be provided with a dedicated

fused disconnect.

b. Install wiring and ground boiler in accordance

with requirements of authority having jurisdiction. In absence of such requirements, reference the National Electrical Code, ANSI/ NFPA 70 and/or CSA C22.1 Electrical Code.

c. Refer to Figure 1 for electrical data for each size

boiler.

d. Refer to the Electrical section for further

warnings, cautions, notices and instructions.

NOTICE

CAUTION

Failure to properly pipe condensate system will greatly reduce boiler life. Do not install plugs, caps or valves on condensate piping.

Do not manifold boiler condensate drains or vent drains together.

Do not crimp condensate lines or reduce drain line inner diameter size.

Each condensate drain must contain a siphon/

pigtail or trap to prevent ue gas ow through the

condensate piping. The height of the top of the syphon/pigtail loop or trap shall not exceed the height of the condensate drain outlet.

Do not install boiler and circulator pump on the same fused disconnect.

8. Condensate Piping

a. Each boiler requires separate condensate drains.

In addition, most venting congurations require

separate condensate drains in the vent system.

b. Refer to Section H for condensate removal

system.

H. CONDENSATE DRAINS

1. Each boiler contains a condensate drain. In

addition, most vent congurations require a drain

tee located in the vent piping. Pipe each condensate

drain separately to a oor drain or condensate pump/

sump.

2. Use continuous Teon, high temperature resistant

silicone tubing, or other tubing material compatible

with ue gas condensate, for condensate piping. Do

not install valves on condensate drain lines.

3. A common condensate pump/sump may be used. Run separate piping from each condensate drain to the sump. A common drain may be used to discharge condensate from the sump. Consult pump/sump manufacturer for compatibility of pump/sump materials of construction. If a common sump is used, individual drain lines should be connected such that one drain cannot back feed into another drain.

4. Consult local authorities regarding disposal of ue

gas condensate into public waste water system. Some jurisdictions require that the condensate be buffered before discharge. This buffering is commonly achieved by draining the condensate through a limestone (calcium carbonate) bed. The condensate will be slightly acidic and range between 3-5 on the pH scale. Consult Thermal Solutions or a chemical treatment company for buffering systems.

CAUTION

Do not use material that is not approved for use

with ue gas condensate for condensate piping.

IV. System Start-up

CAUTION

Failure to properly pipe boiler may result in improper operation and damage to boiler or structure.

Proper water treatment is required to avoid scale

build-up on the inside of the boiler. Thermal Solutions standard warranty does not cover problems caused by scale build-up.

On an existing or retrot system, a lter or

strainer must be installed on the system return prior to the boilers.

When using Glycol products, all Glycol manu-

factures' requirements, including rust inhibitors,

must be adhered. Max 50% Glycol.

A. System Check

1. Verify that the venting, water piping, gas piping and electrical system are installed properly. Refer to installation instructions contained in this manual.

supplied with the boiler conforms to Table 3 for maximum and minimum supply pressures.

2. Open the manual gas shut-off valves located

upstream of the gas regulator supplied with the boiler. Do not open manual gas valve inside of boiler jacket.

DANGER

Do not use matches, candles, open ames or

other ignition source to check for leaks.

3. Using soap solution, or similar non-combustible solution, electronic leak detector or other approved method, check that boiler gas piping valves, regulators and all other components are leak free. Eliminate any leaks.

4. Purge gas line of air.

5. Reset low gas pressure safety switch.

F. Turn the boiler operating switch to the on position.

1. Allow boiler to complete prepurge and trial for

ignition period. Once pilot ame is recognized by controller, position ame control switch to test

position.

2. Look through the boiler sight glass and conrm that

pilot ame is blue and steady and that the ame

signal is steady and between 1.5 and 5.0 volts DC.

On some boiler sizes, the pilot ame may not be visible. In these cases, conrm proper ame signal

(as indicated above.)

3. Adjust pilot gas regulator until proper pilot manifold

gas pressure is achieved per retest report label. Pilot ame should be blue with very little yellow.

4. Turn the boiler off, place ame control switch in

"run" position, and repeat Steps H.1 and H.2 at least

ve times until reliable pilot ignition and signal is achieved and conrmed.

5. With the pilot operating properly, allow boiler to

continue to trial for main ame. Conrm that the ame control locks out on main ame failure.

6. Open the manual main gas shut-off valve located

inside the boiler jacket. Using the procedure detailed in Step E.3, leak test gas piping and valves upstream of the boiler main gas valve. Eliminate any leaks.

7. Reset ame safeguard and allow boiler to run

through prepurge, trial for pilot and trial for main

ame.

8. Conrm that main ame ignites smoothly.

9. Observe main ame and conrm that burner element is evenly orange without ickering.

10. Observe ame signal and conrm signal is steady

and between 1.5 and 5.0 volts DC.

11. Using the procedure detailed in step E.3, leak test gas piping and valves downstream of the boiler gas valve. Eliminate any leaks.

12. Turn boiler off and repeat Steps H.7-H.10 at least

ve times to conrm proper main burner operation.

DANGER

I. Begin Commissioning the boiler - With main ame

on, at high re, measure gas pressure upstream and

downstream of the main gas valves

1. Adjust the manifold pressure to match the pressure

indicated on the factory retest label.

2. Ensure that the inlet gas pressure is within the acceptable range found in Table 3. Adjust if necessary.

WARNING

Failure to properly adjust gas input rate will

result in over ring or under ring of the

appliance. Improper and unsafe boiler operation may result.

3. Conrm that high and low gas pressure switches are functioning and are adjusted to prevent over ring or under ring of the boiler.

4. Adjust setting of air lter ow switch by rotating knob on switch counter clockwise until change

lter light switch is illuminated. Turn switch knob

clockwise ¼ turn past the point where the change

lter light goes out. Replace upper front jacket

panel.

5. With boiler running and all panels attached, measure oxygen (O2) and carbon monoxide

(CO) concentrations in the ue gas and ue gas

temperature. Compare results with values given on

factory retest report supplied with the boiler.

Failure to properly adjust excess air will result in unsafe levels of carbon monoxide. Variations in venting or combustion air pressure and temperature will change excess air. Adjust excess air levels so that variation in venting or combustion air pressures and temperatures caused by change of seasons, wind conditions, opening or closing of boiler room doors or windows do not cause the boiler to operate with carbon monoxide concentrations above 400 parts per million.

6. Verify that all safety and operating limits and ame

controls are operating properly. These controls and limits include combustion air switch, water temperature operating control, manual reset water temperature safety limit, vestibule fuseable link, mixer fuseable link, high and low gas pressure switches. Refer to manuals for these components for proper start-up and operating instructions. Follow all instructions contained in these manuals. This manual was provided with the boiler.

J. Finish Commissioning at the Boiler - Reconnect any

wires from the external control system, if applicable.

1. Test function of external control system.

2. Place system control back in normal operation, if

necessary.

K. Water Treatment - Contact reputable chemical

treatment company for recommendations on proper water treatment for the installation. Each installation is different and must be analyzed based on local water conditions and boiler operating schedule.

The treatment chemicals must be compatible with

copper, bronze, steel and cast iron materials of construction.

CAUTION

A proper water treatment and a monitoring program will extend the life of the boiler. The water shall have a maximum water hardness of 8.5 grains or 150 ppm. The recommended pH range is 8.8 to 9.2. However,

other aspects of water quality can affect boiler operation and longevity. A qualied water treatment expert

should be consulted to develop a complete water treatment plan.

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.

If the power draw of the control circuit exceeds approximately 5 amps, the circuit breaker trips and prevents the boiler from powering until circuit breaker is reset.

If this switch is in the off position, power is interrupted to the control circuit of the boiler which prevents the boiler from operating. If the switch is in the on position, power is supplied to the control circuit.

If the boiler water temperature exceeds the adjustable set point, power is interrupted to the control circuit of the boiler which prevents the boiler from operating. When the boiler water temperature drops below the set point minus the adjustable differential setting, power is again supplied to the control circuit.

If the boiler water temperature exceeds the adjustable set point, power is interrupted to the control circuit of the boiler which prevents the boiler from operating. Power is interrupted until the control is manually reset by pressing the control's reset button. When the button is depressed, power will again be supplied to the control circuit.

If the water ow through the boiler drops below the xed ow rate required to move the

control's paddle enough to close the controls contacts, power is interrupted to the control

circut, which prevents the boiler from operating. When the water ow rate is increased, the

paddle closes the control's contacts and power is supplied to the control circuit.

If the pressure inside the appliance exceeds the xed set point, the valve opens mechanically and discharges water. The valve remains open until the pressure inside the appliance drops below the set point.

If the temperature in the interior of the burner exceeds the xed set point, the contacts of

the switch open and power is interrupted to the control circuit which prevents the boiler from operating. Power is interrupted until the switch is replaced.

If the temperature in the interior of the vestibule enclosure exceeds the xed set point, the

contacts of the switch open and power is interrupted to the control circuit which prevents the boiler from operating. Power is interrupted until the switch is replaced.

If the gas pressure reaches a point below the adjustable set point, or above the adjustable set point, the contacts of the switch open and power is interrupted to the control circuit which prevents the boiler from operating. Power is interrupted until gas pressure is between the high and low set points and the control is manually reset by moving the switch to the reset position. The switches will not reset until the gas pressure is within the set point parameters.

If the differential air pressure drops below the xed set point, the contacts of the switch

open and power is interrupted to the control circuit, which prevents the boiler from operat-

ing. Power is interrupted until air ow increases so that the contacts close.

Refer to the manual supplied with the boiler.

The variable frequency drive's primary function is to vary the rotational speed of the blower fan based on the air requirements of the boiler combustion process. The VFD is used for Modulating boilers. The VFD responds to a 4-20 mA signal from the Digital Temperature Controller.

The microprocessor based temperature controller is used on all modulating boilers. The

controller's basic function is to control the ring rate of the boiler based on the difference

between the bulk boiler water temperature and the controller's set-point. The controller also has the ability to change the operating set-point based on an external signal (contact closure for reduced demand setting or outdoor reset.)

IX. Temperature Controller Operation for Modulating Boilers

A. Description

The microprocessor based temperature controller is utilized for all modulating Thermal Solutions water boilers. The basic

function of the controller is to modulate the ring rate of the burner in response to the boiler heat load. The controller monitors

the boiler water temperature through the use of a sensor located in the boiler pressure vessel. The controller compares the boiler

water temperature to the controller’s user dened operating set-point temperature.

An output signal from the microprocessor varies the blower speed through the use of a variable frequency drive (VFD). The gas

valve regulates an appropriate amount of gas ow for a given air ow or blower speed. The user may adjust the operating set-

point temperature for a given application. In addition, the controller has the ability to change to an alternate set-point through an external signal for low load conditions (i.e. weekend use, night setback). Outdoor reset is another standard feature, allowing the

boiler operating temperature to vary based on the outdoor ambient temperature. The typical result is a higher seasonal efciency.

Other features include:

Low Fire Hold Multiple Analog Inputs Multiple Set Points Mod Bus Communications Digital Inputs Manual Overrive

"AUTO TUNE" Optimization

B. Set-Up

All of the control parameters have been set at the factory. There are a few parameters called “Process Parameters” that must be dened by a qualied operator. The table below will help serve as a reference and record when making adjustments.

• Press “EXIT” button and hold for 5 -10 seconds.

• The red light above manual operation (hand) symbol illuminates.

• Press ▲button to raise ring rate. Press ▼ button to lower ring rate.

• 0 = 50% of Maximum ring rate and 100 = 100% of Maximum ring rate

• Press “EXIT” button and hold for 5 –10 seconds to return to automatic ring rate control.

• Automatic mode has been re-activated once the red light above the manual operation symbol goes out.
