Pre-Installation Items
SECTION I - Pre-Installation Items
Code Compliance
This product must be installed in accordance to the following:
- All applicable local, state, national and provincial codes, ordinances, regula­tions and laws.
- For installations in Massachusetts, code requires the boiler to be installed by a licensed plumber or gas fitter, and if antifreeze is utilized, the installation of a reduced pressure backflow preventer device is required in the boiler’s cold water fill or make up water supply line.
- For installation in Massachusetts all direct vented appliances must comply with the guidelines as outlined on page 11.
- The National Fuel Gas Code NFPA54/ ANSI Z 223.1 - Latest edition.
- National Electric Code ANSI/NFPA 70.
- For installations in Canada -“Installation Code for Gas Burning Equipment” CGA/B149.1 or B149.2 Canadian Electrical Code Part 1 CSA C22.1.
- Standards for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1, when required.
Ensure the boiler location allows the combus­tion air/vent piping to be routed directly through the building and terminate properly outside with a minimum amount of length and bends.
Ensure the area chosen for the installation of the PRESTIGE Solo is free of any combustible materials, gasoline and other flammable liquids.
WARNING
Failure to remove or maintain the area free of combustible materials, gasoline and other flammable liquids or vapors can result in severe personal injury, death or substantial property damage.
Ensure the PRESTIGE Solo and its controls are protected from dripping or spraying water during normal operation or service.
The PRESTIGE Solo should be installed in a location so that any water leaking from the boiler or piping connections or relief valve will not cause damage to the area surrounding the unit or any lower floors in the structure.
Boiler Replacement
If the PRESTIGE Solo is replacing an existing boiler, the following items should be checked and corrected prior to installation:
NOTICE
The PRESTIGE Solo boiler gas manifold and gas controls meet the safe lighting and other performance requirements as speci­fied in ANSI Z21.13 latest edition.
Determining Product Location
Before locating the PRESTIGE SOLO check for convenient locations to:
- Heating system piping
- Venting
- Gas supply piping
- Electrical service
- Boiler piping leaks and corrosion.
- Improper location and sizing of the expansion tank on the boiler heating loop.
- If applicable, level and quality of freeze protection within the boiler system.
Recommended Clearances
The PRESTIGE Solo is approved for zero clearance to combustibles, excluding vent and boiler piping.
- Boiler Piping - 1/4 inch from com­bustible materials.
3
Page 10
Pre-Installation Items
- Reference the appropriate vent supple­ment for clearance requirements.
BEST PRACTICES
To provide serviceability to the unit it is recommended that the following clear­ances be maintained:
Top boiler jacket - 24 inches [610 mm].
Front - 24 inches [610 mm].
Bottom boiler piping - 24 inches [610 mm].
Rear - 0 inches
Sides - 6 inches [153 mm]
WARNING
If the clearances listed above cannot be maintained or the enclosure in which the boiler is installed is less than 85 cubic feet, the space must be ventilated. See page 6 for ventilation requirements.
Residential Garage Installations
When installing the PRESTIGE Solo in a resi­dential garage, the following special precautions per NFPA 54/ANSI Z223.1 must be taken:
- Mount the unit a minimum 18 inches [458 mm] above the floor level of the garage. Ensure the burner and ignition devices / controls are no less than 18 inches [458 mm] above the floor level.
- Locate or protect the unit in a manner so it cannot be damaged by a moving vehicle.
Boiler Freeze Protection Feature
The boiler control has a freeze protection feature built in. This feature monitors the boiler temper­ature and responds as follows when no call for heat is present:
- 46ºF Boiler circulator is ON
- 38ºF Boiler circulator is ON and burner operates at low fire
- 50ºF Burner OFF and boiler circulator operates for approximately 10 minutes
NOTICE
When maintaining zero clearance or less than recommended clearances, some product labeling may become hidden and unreadable.
WARNING
When installing the PRESTIGE Solo in a confined space, sufficient air must be provided for proper combustion and venting and to allow, under normal oper­ating conditions, proper air flow around the product to maintain ambient temper­atures within safe limits to comply with the National Fuel Gas Code NFPA 54 ­latest edition.
CAUTION
The boiler freeze protection feature is disabled during a hard lockout, however the CH circulator will operate.
CAUTION
The boiler freeze protection feature is designed to protect the boiler. The boiler should be installed in a primary/sec­ondary piping arrangement if it is installed in an unheated space or exposed to water temperatures of 46ºF or less. See Section IV for primary/sec­ondary piping examples. See Section IX for antifreeze guides.

Combustion Air Contamination
WARNING
If the PRESTIGE Solo combustion air inlet is located in any area likely to cause or contain contamination, or if products, which would contaminate the air cannot be removed, the combustion air must be repiped and terminated to another loca­tion. Contaminated combustion air will damage the unit and its burner system, resulting in possible severe personal injury, death or substantial property damage.
WARNING
Do not operate a PRESTIGE Solo if its combustion air inlet is located near a laundry room or pool facility. These areas will always contain hazardous con­taminants.
Potential contaminating products
- Spray cans containing chloro/fluorocar­bons
- Permanent Wave Solutions
- Chlorinated wax
- Chlorine - based swimming pool chem­icals / cleaners
- Calcium Chloride used for thawing ice
- Sodium Chloride used for water soft­ening
- Refrigerant leaks
- Paint or varnish removers
- Hydrochloric acid / muriatic acid
- Cements and glues
- Antistatic fabric softeners used in clothes dryers
- Chlorine-type bleaches, detergents, and cleaning solvents found in household laundry rooms
- Adhesives used to fasten building prod­ucts and other similar products
Pool and laundry products and common household and hobby products often contain fluorine or chlorine compounds. When these chemicals pass through the burner and vent system, they can form strong acids. These acids can create cor­rosion of the heat exchanger, burner components and vent system, causing serious damage and presenting a possi­ble threat of flue gas spillage or water leakage into the surrounding area.
Please read the information listed below. If contaminating chemicals are located near the area of the combustion air inlet, the installer should pipe the combustion air inlet to an outside area free of these chemicals per SECTION V of this installation manual.
Areas likely to contain these products
- Dry cleaning / laundry areas and estab­lishments
- Beauty salons
- Metal fabrication shops
- Swimming pools and health spas
- Refrigeration Repair shops
- Photo processing plants
- Auto body shops
- Plastic manufacturing plants
- Furniture refinishing areas and estab­lishments
- New building construction
- Remodeling areas
- Garages with workshops

Ventilation and Combustion Air Requirements - Direct Vent
A Direct Vent appliance utilizes uncontamined outdoor air (piped directly to the appliance) for combustion.
For Direct Vent installations, involving only the PRESTIGE Solo, in which the minimum service clearances are maintained as listed on page 4, no ventilation openings are required.
For Direct Vent, zero clearance installations involving only the PRESTIGE Solo, the space / enclosure must provide two openings for ven­tilation. The openings must be sized to provide 1 square inch of free area per 1,000 BTUH of boiler input. The openings shall be placed 12 inches from the top of the space and 12 inches from the floor of the space.
For installations in which the PRESTIGE Solo shares the space with air movers (exhaust fan, clothes dryers, fireplaces, etc.) and other com­bustion equipment (gas or oil) the space must be provided with adequate air openings to pro­vide ventilation and combustion air to the equipment. To properly size the ventilation / combustion air openings, the installer must comply with the National Fuel Gas Code NFPA 54, ANSI Z223.1 for installations in the U.S or CSA B149.1 and B149.2 for installa­tions in Canada.
WARNING
The space must be provided with venti­lation / combustion air openings proper­ly sized for all make-up air requirements (exhaust fans, clothes dryers, fireplaces, etc.) and the total input of all appliances located in the same space as the PRES­TIGE Solo, excluding the input of a Direct Vent PRESTIGE Solo which uses combustion air directly from the outside, thus additional free area for the open­ings is not required. Failure to provide or properly size the openings could result in severe personal injury, death or substantial property damage.
Ventilation and Combustion Air Requirements - Category IV
A Category IV appliance utilizes uncontami­nated indoor or outdoor air (surrounding the appliance) for combustion.
BEST PRACTICES
In order to reduce the potential risks associated with indoor contaminates (listed on page 5), flammable vapors and tight housing construction (little or no infiltration air), it is recommended to pipe uncontaminated combustion air directly from the outdoors to the appli­ance. This practice also promotes higher system efficiency by reducing heated indoor air from being exhausted from the house and replaced by cold infiltra­tion air
into the house.
For installations in which the PRESTIGE Solo shares the space with air movers (exhaust fan, clothes dryers, fireplaces, etc.) and other com­bustion equipment (gas or oil) the space must be provided with adequate air openings to provide ventilation and combustion air to the equipment. To properly size the ventilation / combustion air openings, the installer must comply with the National Fuel Gas Code NFPA 54, ANSI Z223.1 for installations in the U.S or CSA B149.1 and B149.2 for installations in Canada, as referenced in this section of the manual and titled Methods of Accessing Combustion Air into a Space.
WARNING
The space must be provided with venti­lation / combustion air openings proper­ly sized for all make-up air requirements (exhaust fans, clothes dryers, fireplaces, etc.) and the total input of all appliances, including the PRESTIGE Solo when located in the same space. Failure to pro­vide or properly size the openings could result in severe personal injury, death or substantial property damage.

DANGER
Do not install the PRESTIGE Solo into a common vent with other gas or oil appli­ances. This may cause flue gas spillage or appliance malfunction, resulting in possi­ble severe personal injury, death or sub­stantial property damage.
Combustion Air and Vent Piping
The PRESTIGE Solo requires a Category IV venting system, which is designed for pressur­ized venting and condensate.
BEST PRACTICES
In order to reduce the potential risks associated with indoor contaminates (listed on page 5), flammable vapors and tight housing construction (little or no infiltration air), it is recommended to pipe uncontaminated combustion air directly from the outdoors to the appli­ance. This practice also promotes higher system efficiency by reducing heated indoor air from being exhausted from the house and replaced by cold infiltra­tion air into the house.
NOTICE
Install combustion air and vent pipe as detailed in the PRESTIGE Solo Vent Supplement included in the boiler installation envelope. Refer to optional vent kit instructions for addition vent installation instructions.
DANGER
Verify installed combustion air and vent piping are sealed gas tight and meet all provided instructions and applicable codes, failure to comply will result in severe personal injury of death.
The PRESTIGE Solo is certified per ANSI Z21.13 as a Category IV or Direct Vent (sealed combustion) appliance. A Category IV appli­ance utilizes uncontamined indoor or outdoor air (surrounding the appliance) for combustion. A Direct Vent appliance utilizes uncontaminat­ed outdoor air (piped directly to the appliance) for combustion.

Removal of an Existing Boiler from a Common Vent System
BEST PRACTICES
When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the remaining appliances. At the time of removal of an existing boiler, the fol­lowing steps shall be followed with each appliance remaining connected to the com­mon venting system placed in operation, while the other appliances remaining con­nected to the common venting system are not in operation.
1. Seal any unused openings in the common venting system.
2. Visually inspect the venting system for proper size and horizontal pitch and deter­mine there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.
5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or can­dle, or smoke from a cigarette, cigar or pipe.
6. After it has been determined that each appliance remaining connected to the com­mon venting system properly vents when tested as outlined above, return doors, win­dows, exhaust fans, fireplace dampers, and any other gas-burning appliance to their previous condition of use.
7. Any improper operation of the common venting system should be corrected so the installation conforms with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CGA B149, Installation codes. When resizing any portion of the common venting system, the common venting sys­tem should be resized to approach the min­imum size as determined using the appro­priate tables in Part II of the National Fuel Gas Code ANSI Z223.1/NFPA 54 and/or CAN/CGA B149, Installation codes.
3. Insofar as is practical, close all building doors and windows and all doors between the space in which the appliances remain­ing connected to the common venting sys­tem are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.
4. Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliance will operate continuously.
DANGER
Do not install the PRESTIGE Solo into a common vent with other gas or oil appli­ances. This may cause flue gas spillage or appliance malfunction, resulting in possi­ble severe personal injury, death or sub­stantial property damage.

Boiler Piping
SECTION IV - Boiler Piping
General Piping Requirements
- All plumbing must meet or exceed all local, state and national plumbing codes.
- Support all piping using hangers. DO NOT support piping by the unit or its components.
- Use isolation valves to isolate system com­ponents.
- Install unions for easy removal of the PRESTIGE Solo from the system piping.
WARNING
Use a two wrench method when tighten­ing piping onto the boiler connections. Use one wrench to prevent the boiler piping from turning / twisting. Failure to support the boiler piping and connec­tions in this manner to the boiler and its components.
Pressure Relief Valve
1. The PRESTIGE Solo is supplied with a 30 psi pressure relief valve and must be piped using the PRV connection as shown in Fig. 5 page 15.
2. To avoid potential water damage to the sur­rounding area or potential scalding hazard due to the operation of the relief valve, the discharge piping:
- Must be connected to the discharge out-
let of the relief valve and directed to a safe place of disposal.
- Length should be as short and direct as
possible. The size of the discharge line should not be reduced, maintain the same size as the outlet of the relief valve.
- Should be directed downward towards
the floor at all times. The piping should terminate at least 6 inches [153 mm] above any drain connection to allow clear visibility of the discharge.
could cause damage
- Should terminate with a plain end, not with a threaded end. The material of the piping should have a serviceable temperature rating of 250ºF or greater.
- Should not be subject to conditions where freezing could occur.
- Should not contain any shut-off valves or obstructions. No shut-off valve should be piped between the boiler and relief valve.
WARNING
Failure to comply with the guidelines on installing the pressure relief valve and discharge piping can result in personal injury, death or substantial property damage.
Low Water Cutoff Device
- The PRESTIGE Solo is equipped with a fac­tory installed pressure switch type Low Water Cut Off device.
- The minimum operating system pressure allowable with this device is 10 psig.
- Check local codes if a Low Water Cutoff Device is required. If so, determine if this device meets the requirements of the local codes.
NOTICE
The PRESTIGE Solo control system also senses the system water temperatures entering and exiting the heat exchanger to provide protection against low water conditions Where local codes and juris­diction do not accept a pressure device for low water protection, the jurisdic­tions may accept these PRESTIGE Solo integral control functions as a means of providing low water protection.

Additional Limit Control
If a separate LWCO device is required by cer­tain local jurisdictions or when the boiler is installed above the system piping, the follow­ing guidelines must be followed:
- The LWCO device must be designed for water installations, electrode probe­type is recommended.
- The LWCO device must be installed in a tee connection on the boiler supply piping above the boiler.
- Wiring of the LWCO device to the PRESTIGE Solo is done directly onto the 24V terminal strip, reference Fig. 20 page 32 for available terminals for an external limit (manual or auto reset).
If the installation is to comply with ASME or Canadian requirements, an additional high temperature limit may be needed. Consult local code requirements to determine compli­ance. The limit should be installed as follows:
- Install the limit in the boiler supply pip­ing between the boiler and any isolation valve.
- Maximum set point for the limit is 194ºF.
- For wiring of the limit reference Fig. 20, page 32, using the external limit/manual reset terminals on the 24V terminal strip. This will provide a "hard" lockout requiring a manual reset of the control.
Boiler System Piping Applications
BEST PRACTICE
It is recommended on all piping applica­tions to utilize a primary/secondary pip­ing arrangement as a means to provide freeze protection of the boiler, which is an integral function of the boiler control. Maintain the minimum boiler flow rate, see Graphs 2 through 5 on pages 72 & 73. For other piping arrangements, consult the Engineering Department at Triangle Tube or consult other approved/recog­nized design arrangements.
BEST PRACTICE
On piping applications utilizing a single zone or other recognized piping design arrangements, it is recommended that the installer uses flow/check valves with weighted seats at or near the appliance to prevent gravity circulation.
Expansion Tank and Makeup Water
Ensure the expansion tank is properly sized for the boiler volume (3 gallons [12 L] for the PRESTIGE Solo 60, 5 gallons [19 L] for the PRESTIGE Solo 175/250, 7 gallons [26 L] for PRESTIGE Solo 399) and the system volume and temperature.
CAUTION
Backflow Preventer
- Use a backflow preventer valve in the make-up water supply to the unit as required by local codes.
Undersized expansion tanks will cause system water to be lost through the pres­sure relief valve and cause additional makeup water to be added to the system. Eventual boiler heat exchanger failure can result due to this excessive makeup water addition.
16
Page 23
Boiler Piping
The expansion tank must be located as shown in Fig. 6 and Fig. 7 on page 18 when using a primary/secondary piping arrangement or as per recognized design methods. Refer to the expansion tank manufacturer instructions for additional installation details.
Connect the expansion tank to an air separator only if the air separator is located on the suc­tion side (inlet) of the system circulator. Always locate and install the system fill con­nection at the same location as the expansion tank connection to the system.
Diaphragm Expansion Tank
Always install an automatic air vent on the top of the air separator to remove residual air from the system.
Closed-Type Expansion Tank
It is recommended to pitch any horizontal pip­ing upwards toward the expansion tank 1 inch per 5 feet of piping. Use 3/4” piping for the expansion tank to allow air within the system to rise.
Sizing Primary Piping
See Fig. 8 through 14, pages 20 - 24, for rec­ommended piping arrangements based on vari­ous applications. Size the piping and system components required in the space heating sys­tem, using recognized design methods.
Domestic Hot Water System Piping
See Fig. 8 , page 20 for recommended piping to a DHW system. This recommended piping configuration ensures priority is given to the production and recovery of the DHW.
The piping for the DHW is separate from the boiler system piping and does not require a pri­mary / secondary piping configuration.
To wire the DHW circulator to the boiler con­trol module, reference Section VIII - External Wiring.
System Piping - Zone Circulators
Connect the PRESTIGE Solo to the system piping as shown in Fig. 9 page 21 when zoning with zone circulators.
CAUTION
DO NOT install automatic air vents on a closed-type expansion tank system. Air must remain in the system and be returned to the expansion tank to pro­vide an air cushion. An automatic air vent would cause air to be vented from the system resulting in a water-logged expansion tank.
Circulator
The PRESTIGE Solo must be supplied with a Central Heating (CH) circulator. The circulator when wired directly to the PRESTIGE Solo will allow for domestic hot water priority and to provide circulation for the freeze protection feature of the boiler control. See Graphs 2 through 5 on pages 72 & 73 for pressure drop and minimum flow rate through the boiler.
The installer must provide a separate circulator for each zone of space heating as well as the boiler circulator.
NOTICE
To ensure an adequate flow rate through the PRESTIGE Solo, the boiler supply and return piping size must be a mini­mum of 1 inch for the PRESTIGE Solo 60, 1-1/4 inch for the PRESTIGE Solo 175/250 and 1-1/2 inch for the PRES­TIGE Solo 399.

Boiler Piping
System Piping - Zone Valves
Connect the PRESTIGE Solo to the system pip­ing as shown in Fig. 10 page 21 when zoning with zone valves. The primary / secondary piping ensures that the boiler loop has sufficient flow.
NOTICE
To ensure an adequate flow rate through the PRESTIGE Solo, the boiler supply and return piping size must be a mini­mum of 1 inch for the PRESTIGE Solo 60, 1-1/4 inch for the PRESTIGE Solo 175/250 and 1-1/2 inch for the PRESTIGE Solo 399.
System Piping - Through Boiler
In new or retrofit applications in which primary/secondary arrangement is not utilized, the PRESTIGE Solo allows this flexibility due to a lower boiler pressure drop, see Graphs 2 through 7 on pages 75 through 77.
Figure 11, page 22 illustrates a multiple zone valve system with a single system/boiler circu­lator. A by-pass loop with a pressure differential valve must be installed on the system piping.
Figure 12, page 22 illustrates a single zone utiliz­ing the boiler circulator as the system circulator.
System Piping - Radiant Heating
The heat exchanger design of the PRESTIGE Solo allows operation in a condensing mode. This feature requires no regulation of the return water temperature back to the boiler in radiant heating applications.
The boiler water supply temperature can be maintained by the PRESTIGE Solo, eliminat­ing the need for a mix system to achieve the desired temperature.
It is recommended for the installer to add a high temperature limit as shown in Fig.13 page
23. This will ensure that the primary supply temperature does not exceed the maximum allowable temperature for the radiant tubing.
BEST PRACTICE
The addition of the high temperature limit is important if the PRESTIGE Solo is connected to a domestic hot water sys­tem, which requires a high primary sup­ply water temperature.
Size the system piping and circulator to provide the flow needed for the radiant system.
NOTICE
To ensure an adequate flow rate through the PRESTIGE Solo, the boiler supply and return piping size must be a mini­mum of 1 inch for the PRESTIGE Solo 60, 1-1/4 inch for the PRESTIGE Solo 175/250 and 1-1/2 inch for the PRES­TIGE Solo 399.
System Piping - Special Application
If the boiler is used in conjunction with a chilled water/medium system, the boiler and chiller must be piped in parallel. Install flow/check valves to prevent the chilled medi­um from entering into the boiler.
If the boiler is used to supply hot water to the heating coils of an air handler where they may be exposed to chilled air circulation, install flow/check valves or other automatic means to prevent gravity circulation of the boiler water during cooling cycles.
System Piping - Multiple Units Installation
Use a balanced manifold system as the prima­ry / secondary connection to the space heating piping as shown in Fig. 14 page 24.
Maintain a minimum of 6 inches [153 mm] of clearance between units to allow for servicing.
Refer to Figs. 6 and 7 page 18 to install air sep­arator and expansion tank.
For the space heating piping refer to the appli­cations mentioned in this manual or use recog­nized design methods.

Refer to optional vent kit instructions for additional vent installation instructions. Once installa­tion is completed, inspect the vent and combustion air system thoroughly to ensure systems are airtight and comply with the instructions given in the venting supplement and are within all require­ments of applicable codes. Failure to comply with the installation require­ments on the venting and combustion air piping will cause severe personal injury or death.
WARNING
Ensure the condensate drain assembly contains the plastic seated ball. Do not install the condensate drain assembly if the ball is lost or missing, replace the entire assembly.
3. Remove the compression nut and rubber seal from the drain outlet.
4. Using 3/4” x 2’ flexible PVC tube provid­ed, slide the compression nut and rubber seal over the pipe
NOTICE
The use of 3/4” PVC or CPVC pipe is also acceptable. If 3/4” pipe is used deburr and chamfer pipe to allow mat­ing onto the drain assembly.
5. Thread the rubber seal into the compres­sion nut to ease installation of the pipe to the drain assembly.
Installing Condensate Drain Assembly
1. Locate the condensate drain assembly and install as shown in Fig. 15 page 26.
NOTICE
The installer may want to fill the con­densate trap with water prior to assem­bling on the unit.
2. Remove the retaining nut and rubber seal from the condensate drain assembly and slide over the heat exchanger condensate drain nipple. Connect the condensate drain assembly to the retaining nut and tighten.
Hand tight only!
6. Seat the pipe onto the drain assembly and tighten the compression nut.
Hand tight
only!
NOTICE
The installer may opt to using 13/16" ID tubing in lieu of rigid piping.
NOTICE
The drain line materials must be an approved material by the authority hav­ing jurisdiction. In absence of such authority, PVC and CPVC piping must comply with ASTM D1785 or D2845. The cement and primer used on the pip­ing must comply with ASME D2564 or F493. For installations in Canada, use CSA or ULC certified PVC or CPVC pipe, fittings and cement/primer.

CAUTIONNOTICE
When selecting and installing a conden­sate pump, ensure the pump is approved for use with condensing boilers and fur­naces. The pump should be equipped with an overflow switch to prevent prop­erty damage from potential condensate spillage.
8. The PRESTIGE Solo will typically produce a condensate that is considered slightly acidic with a pH content below 3.0. Install a neutralizing filter if required by authority having jurisdiction.
The condensate drain must remain filled and unobstructed and allow unrestricted flow of condensate. The condensate should not be subject to conditions where freezing could occur. If the con­densate is subjected to freezing or becomes obstructed , it can leak, result­ing in potential water damage to the boil­er and surrounding area.

Start-Up Preparation
SECTION IX - Start-Up Preparation
Flush Boiler and Domestic System to Remove Sediment
Check Boiler System Water Chemistry
WARNING
Do not use petroleum-base cleaning or sealing compounds in the boiler system. Damage to seals and gaskets in the sys­tem components could occur, resulting in substantial property damage.
NOTICE
System water including additives must be practically non-toxic, having a toxicity rating or Class of 1, as listed in Clinical Toxicology of Commercial Products.
Water pH Level 6.0 to 8.0
Maintain the boiler water pH between 6.0 and
8.0. Check using litmus paper or contact a water treatment company for a chemical analysis.
The installer must flush the boiler system to remove any sediment to allow proper operation of the PRESTIGE Solo .
Flush the systems until the water runs clean and is free of sediment.
For zoned systems, each zone should be flushed through a purge valve. Purge valves and isolation valves should be installed on each zone to allow proper flushing of the system.
Check and Test Antifreeze
For boiler systems containing antifreeze solu­tions, follow the antifreeze manufacturer’s instructions in verifying the inhibitor level and to ensure the fluid characteristics are within specification requirements.
Due to the degradation of inhibitors over time, antifreeze fluids must be periodically replaced. Refer to the manufacturer of the antifreeze for additional instructions.
If the pH does not meet this requirement, do not operate the PRESTIGE Solo or leave the unit filled until the condition is corrected.
Water Hardness Less Than 7 Grains
For areas with unusually hard water (hardness above 7 grains) consult a water treatment company.
Chlorinated Water
Do not use the PRESTIGE Solo to heat a swimming pool or spa directly.
Maintain the chlorine level of the water at lev­els considered safe for drinking.
NOTICE
System water including additives must be practically non-toxic, having a toxicity rating or Class of 1, as listed in Clinical Toxicology of Commercial Products.
37
Page 44
Start-Up Preparation
Use of Antifreeze in the Boiler System
WARNING
NEVER use automotive or ethylene gly­col antifreeze or undiluted antifreeze in the primary system as freeze protection. This can cause severe personal injury, death or substantial property damage if ignored.
Determine the antifreeze fluid quantity using the system water content volume and following the antifreeze manufacturer instructions.
The water volume of the PRESTIGE Solo is approximately 3 gallons [12 L] for PRESTIGE Solo 60 or 5 gallons [19 L] for PRESTIGE Solo 175/250 or 7 gallons [26 L] for PRESTIGE Solo 399 . Remember to include the volume of the expansion tank.
Check with local codes requirements for the installation of backflow preventers or actual disconnection from the boiler’s cold water fill or make up water supply line.
NOTICE
Massachusetts Code requires the installa­tion of a backflow preventer if antifreeze is used.
2. Open all system isolation valves.
3. Fill the boiler system to correct system pressure. Correct pressure will vary with each application.
NOTICE
Typical residential system fill pressure is 12 psi. System pressure will increase when system temperature increases. Operating pressure of the system should never exceed 25 psi.
4. Purge air and sediment in each zone of the boiler system through the purge valve. Open air vents to allow air to be purged in the zones.
5. Once the system is completely filled and purged of all air and sediment, check the system pressure and check/repair any leaks.
WARNING
Unrepaired system leaks will cause con­tinual makeup water to be added to the boiler. Continual makeup water could cause mineral buildup within the heat exchanger, reducing the heat transfer, causing possible heat buildup and even­tual heat exchanger failure.
Ensure the concentration of antifreeze to water does not exceed a 50/50 ratio.
NOTICE
System water, including additives, must be practically non-toxic, having a toxicity rating or Class of 1, as listed in Clinical Toxicology of Commercial Products.
Filling the Boiler System
1. Close the boiler drain valve located on the bottom of the unit and any manual or auto­matic air vent in the system.
Check Low Water Cut-Off Device
- The PRESTIGE Solo is provided with a factory installed LWCO device that mea­sures system pressure of more than 10 psi.
- Remove the front jacket panel and check for continuity across the low water cut-off device wire terminals. The contacts should be closed when system pressure is greater than 10 psi. See item 6, on Fig. 27 page 66 (PRESTIGE Solo 60) or on Fig. 27A page 67 (PRESTIGE Solo 175/250) or Fig. 27B page 68 (PRESTIGE Solo 399) for location of the LWCO.

Start-Up Preparation
Check For Gas Leaks
WARNING
Prior to start-up and during initial opera­tion, smell near the floor and around the unit for gas odorant or any unusual odor. Do not proceed with the start-up if there is any indication of a gas leak. Any leaks found must be repaired immediately.
WARNING
Propane installations only - The propane supplier mixes an odorant with the propane to make its presence detectable. In some cases the odorant can fade and the gas may no longer have an odor.
Prior to start-up of the unit and periodi­cally after start-up have the propane supplier check and verify the odorant level.
NOTICE
In systems using 3-wire zone valves, backfeed of voltage to the unit is a com­mon problem. Use an isolation relay to prevent voltage from the external circuit entering the PRESTIGE Solo control panel.
- Reconnect the external thermostat
wires to the 24V terminal strip on the wiring panel.
Inspection of Condensate Drain Assembly
1. Inspect and ensure the Condensate Drain Assembly is properly installed as described on page 25 and shown in Fig. 15 on page
26.
2. Remove the plug from the Condensate Drain Assembly and fill with fresh water.
Check Thermostat Circuit
- Disconnect the external thermostat wires from the 24V terminal strip on the wiring panel.
- Connect a voltmeter across the wire ends of the external thermostat wiring.
- Close each thermostat, zone valve and relay in the external circuit one zone at a time and check the voltage reading across the wire ends.
- There should
NEVER be voltage measured
at the wire ends.
- If voltage is measured at the panel under any condition, check and correct the external wiring.
NOTICE
The condensate drain assembly must be filled with water when the PRESTIGE Solo is in operation. The condensate drain assembly prevents flue gas emis­sions from entering the condensate line. Failure to ensure trap is filled with water could result in severe personal injury or death.
3. Re-Install plug in condensate drain assem­bly.

operation of the PRESTIGE Solo control.
c Verify the PRESTIGE Solo and the boiler
system are full of water and all system components are correctly set for operation, including the minimum flow rate through the boiler, see pages 79 through 81.
c Verify Start-up Preparation items outlined on
pages 37 thru 39 have been completed.
c Verify all electrical connections are correct
and securely fastened.
c Inspect vent and combustion air piping for
signs of deterioration from corrosion, physical damage or sagging. Verify combustion air and vent piping are intact and correctly installed and supported. Reference the PRES­TIGE Solo vent supplement.
c Verify burner configuration - Propane only.
- Check for proper labeling on the gas valve and the rating label for propane configuration.
- If there is doubt on the burner configura­tion, remove the gas valve and check for proper propane gas orifice size: 0.120” or
3.1 mm for PRESTIGE Solo 60, 0.221” or
5.6mm for PRESTIGE Solo 175, 0.250” or
6.3 mm for PRESTIGE Solo 250 or 0.264” or 6.7 mm for PRESTIGE Solo 399. Refer to Figs. 17 & 18, page 30 for location of the propane gas orifice.

Start-Up Procedures
c Check Vent Piping and Combustion Air
Piping.
Check for gas-tight seal at every con­nection and seam of the venting and combustion air piping.
WARNING
Venting system must be sealed gas-tight to prevent flue gas spillage and potential carbon monoxide emissions, which will result in severe personal injury or death.
c Check Gas Piping
Check around the unit for gas odor fol­lowing the procedure outlined in this manual on Page 39.
WARNING
If any gas leaks are found or suspected, shut the unit down immediately. Use a gas detection device or bubble test to locate the source of the gas leak and repair at once. Do not operate the unit until the leak is corrected. Failure to comply with this procedure could result in severe personal injury, death or sub­stantial property damage.
Test for CO2 or O2 and for CO during high firing rate. To manually place the boiler into high fire mode, reference page 45. The combustion reading should be within the range listed in Table 2.
The CO level should not exceed 100 ppm when combustion is correct.
WARNING
The combustion levels should be mea­sured at high firing rate, refer to page 45 of the PRESTIGE Solo control section on how to set the firing rate. If the com­bustion levels are not within the range given in Table 2 for the firing rate, shut the boiler down and contact Triangle Tube Engineering Department. Failure to comply with this requirement could result in severe personal injury, death or substantial property damage.
Table 2: Recommended Combustion Levels
c Verify Flame Pattern and Combustion
Check the flame pattern through the inspection port of the heat exchanger. The flame should be blue and stable. The flame should be the length of the burner head openings.
WARNING
The combustion testing and adjustments must be performed by a qualified installer, service agency or the gas suppli­er. All combustion measurements must be performed with calibrated equipment to ensure proper reading and accuracy.

Outdoor Reset Control
SECTION XI - Outdoor Reset Control
The boiler setpoint for a heating call can be fixed or vary with the outdoor temperature. If the application requires a constant supply tem­perature from the boiler, the outdoor tempera­ture sensor should not be connected to the boil­er. If an outdoor temperature sensor is con­nected to the boiler, the outdoor reset function is automatically enabled and will vary the CH setpoint with the change in outdoor tempera­ture. The outdoor reset function has no affect on the DHW setpoint during a domestic call.
4. Mount the sensor enclosure at an elevation on the exterior wall to prevent accidental damage or tampering.
5. Avoid mounting the enclosure in areas sub­jected to excessive moisture.
6. Once an area on the exterior wall has been determined, to affix the enclosure use the enclosure as a template to mark the location of the mounting screws.
7. Using a 3/16” drill bit, drill 2 pilot holes on the marked locations.
8. Tap the enclosed plastic anchors into the pilot holes. Use care not to damage the anchors.
Mount the sensor enclosure using the
9. screws provided.
Wiring the Sensor
1. Remove the sealing nut and sealing gasket from the sensor enclosure.
Fig. 25: Sensor Enclosure and Components
Mounting the Outdoor Sensor
1. Remove the front cover and mounting screws / anchors from the sensor enclosure.
2. When mounting the enclosure the exterior wall selected should represent the heat load of the building. Typically a northern or northeastern wall will suit most buildings. A southern facing wall may suit buildings that have large glass walls or windows on the southern face.
3. Ensure the sensor enclosure is shielded from direct sunlight or the effects of heat or cold from other sources (exhaust fans, appliance vents...) to prevent false temper­ature sensing.
2. Route two 18 gauge wires through the seal­ing nut and gasket. Connect the wires to the sensor terminals 1 and 2.
3. Re-insert the sealing gasket and tighten the sealing nut to the sensor enclosure.
4. Route the sensor wire back to the PRES­TIGE Solo boiler, ensuring the wires are not run parallel to telephone or power cables.
NOTICE
If the sensor wires are located in an area with sources of potential electromagnetic interference (EMI) the sensor wires should be shielded or the wires should be routed in a grounded metal conduit. If using shielded cable, the shielding should be connected to the common ground of the unit.
5. Connect the sensor wires to the outdoor sen­sor terminals on the 24V terminal strip locat­ed inside the boiler enclosure (see boiler wiring diagram, Fig. 20 page 32).

External Modulating Control
SECTION XII - EXTERNAL MODULAT­ING CONTROL
The boiler can directly accept an analog 0-10 VDC signal to control the firing rate from an external modulating boiler controller.
Wiring the Modulating Controller
Run two 18 gauge wires from the external modulating boiler controllers 0-10 VDC boiler output to the external input terminals on the low voltage terminal strip inside the boiler. (see boiler wiring diagram, Fig. 20 page 32). This signal will both enable and modulate the boil­er. No wiring is required at the thermostat (T­T) terminals 7 and 8 of the boiler.
NOTICE
Ensure that the polarity of the connec­tions from the external modulating boil­er controller to the boiler is correct. Reversed polarity could lead to erratic and/or no response from the boiler con­troller.
NOTICE
Ensure that Parameter 4 is set above the highest setpoint of the external modulat­ing control. Paramater 4 is a boiler high temperature limit when using an exter­nal modulating controller.
Programming of External Modulating Control
The external modulating control must be pro­grammed to send 1.8 VDC to enable the boiler and run it at low fire, and 10 VDC to run the boiler at high fire. Once the control enables the boiler, it must wait 2 minutes to allow the burn­er to stabilize before modulating the boiler.
Parameter Adjustment
The Prestige MCBA control module must be programmed to accept the 0-10 VDC signal from the external modulating boiler control.
CH Operating Signal Section (Parameter 45)
Follow the procedure for entering the MCBA Access Code on page 52, and then change the setting of Paramater 45 from the factory setting of 00 to 02.

failure. Leaking water may also cause severe property damage to the sur­rounding area. Inspect the gas supply piping using the procedure outlined on Page 41.
Page 66
Maintenance Procedures
Clean Condensate Drain Assembly
1. Loosen the retaining nut from the conden­sate drain assembly and disconnect the assembly from the boiler.
2. Empty any water from the trap and drain assembly. Flush with fresh water as neces­sary to clean.
3. Check the drain piping from the condensate drain assembly to the drain. Flush to clean as necessary.
4. Reassemble the condensate drain assembly onto the boiler by tightening the retaining nut with rubber seal onto the boiler. Hand tight only.
5. Remove the fill plug on the condensate drain assembly and fill with water. See Fig. 15 on page 26.
6. Replace the fill plug on drain assembly.
Check Ventilation Air Openings
Inspect Vent and Combustion Air Piping
Visually inspect the venting system and com­bustion air piping for blockage, deterioration or leakage. Repair any deficiencies.
Verify that the combustion air inlet piping is connected, sealed and properly supported.
WARNING
Failure to inspect the vent system and combustion air inlet piping and to have any conditions repaired, can result in severe personal injury or death.
Check Boiler System
Verify all system components are correctly installed and operating properly.
Check the cold fill pressure for the system, typ­ical cold water fill pressure is 12 psig.
Verify that all ventilation openings to the mechanical room or building are open and unobstructed. Check the operation and wiring of any automatic ventilation dampers.
Check and verify the vent discharge and the combustion air intake are free of debris and obstructions.
Verify the system pressure, as the unit operates at high temperature, to ensure the pressure does not exceed 25 psig. Excessive pressure reading indi­cates expansion tank sizing is incorrect or system performance problems.
Inspect air vent and air separators in the sys­tem. Remove the caps on automatic air vents and briefly depress the valve stem to flush vent. Replace the cap when completed. Ensure vents do not leak, replace any leaking vents.

Maintenance Procedures
Check Expansion Tank
Refer to Section IV - Boiler Piping for rec­ommended location of the expansion tank and air eliminators.
Closed -Type Tank:
- Ensure tank is partially filled with
water leaving an air gap as a cushion. Refer to the manufacturer’s instruction for proper fill level.
- Ensure the tank is fitted with a device
that reduces gravity circulation of air­saturated tank water back into the sys­tem. This device prevents air from bubbling up through the water as it returns from the system.
- Ensure no automatic air vents are used
in the system. This will allow air to escape from the system instead of returning to the tank.
Diaphragm Tank:
- Ensure the system contains a minimum of
one automatic air vent. Recommended location of the air vent should be atop an air eliminator.
- Remove the tank from the system and
check the charge pressure. For residen­tial applications the charge pressure is typically 12 psig. If tank does not hold a charge pressure, then the membrane is damaged and the tank should be replaced.
WARNING
Before manually operating the pressure relief valve, ensure the discharge piping is directed to a suitable place of disposal to avoid a potential scald hazard. The dis­charge piping must be full size without restriction and installed to permit com­plete drainage of both the valve and line.
If after closing the valve, the valve fails to seat properly or continually weeps, replace the relief valve. Ensure the cause of the relief valve to weep is the valve itself, not due to sys­tem over-pressurization caused by an expan­sion tank that is waterlogged or undersized.
Inspection of Ignition Electrode
Remove the ignition electrode from the burner mounting plate.
Remove any white oxides accumulated on the electrode using fine grit sandpaper or steel wool. If the electrode does not clean to a satisfactory condition, replace the ignitor.
When replacing the ignition electrode, ensure the gasket is in good condition and correctly positioned, replace gasket if necessary.
Check Ignition Wiring and Ground Wiring
Inspect the burner wiring from the burner con­trol module to the ground terminal behind the control panel.
Check Boiler Relief Valve
Inspect the relief valve and lift the lever to ver­ify flow at least annually or as recommended on the warning tag of the valve.
Ensure wiring is in good condition and secure­ly connected.
Check ground continuity of the wiring to the boiler jacket or piping using a continuity meter
Replace and correct ground wire if ground con­tinuity is not completed and satisfactory.
