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

Combustion Air Venting

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 PRACTICE

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.

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.

The PRESTIGE Solo requires a Category IV venting system, which is designed for pressurized venting and condensate.

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.

BEST PRACTICE

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.

Page 16

Combustion Air Venting

Removal of an Existing Boiler from a Common Vent System

BEST PRACTICE

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.

Page 20

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 could cause damage 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.

- 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 low voltage terminal strip, reference Fig. 19 page 31 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:

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 7 on pages 91 through 93. 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.

- 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. 19, page 31, using the external limit/manual reset terminals on the low voltage terminal strip. This will provide a "hard" lockout requiring a manual reset of the control.

Backflow Preventer

- Use a backflow preventer valve in the make-up water supply to the unit as required by local codes.

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

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.

The expansion tank must be located as shown in Fig. 7 and Fig. 8 on page 19 when using a primary/secondary piping arrangement or as per recognized design methods. Refer to the expansion tank manufacturer instructions for additional installation details.

Page 23

Boiler Piping

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.

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

Domestic Hot Water System Piping

See Fig. 9 through 12, page 21-22 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.

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.

The PRESTIGE Solo requires an external circulator to provide circulation through the boiler. 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 7 on pages 91 & 93 for pressure drop and minimum flow rate through the boiler.

Sizing Primary Piping

See Fig. 9 through 13, pages 21 - 23, for recommended piping arrangements based on various applications. Size the piping and system components required in the space heating system, using recognized design methods.

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.

Boiler Piping

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 91 through 93.

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 allows operation in a condensing mode. This feature requires no regulation of the return temperature back to the boiler in radiant heating applications.

The design and construction of the PRESTIGE heat exchanger allows the installation of the boiler on systems with non - oxygen barrier tubing.

NOTICE

The addition of the high temperature limit is important if the PRESTIGE is connected to a domestic hot water system, which requires a high primary supply water temperature.

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.

CAUTION

DO NOT install a SMART tank along with the PRESTIGE in systems with non-oxygen barrier tubing. Failure to comply could result in premature failure of the SMART tank.

The boiler water supply temperature can be maintained by the PRESTIGE, eliminating the need for a mix system to achieve the desired temperature.

It is recommended for the installer to install a high temperature limit to ensure that the primary supply temperature does not exceed the maximum allowable temperature for the radiant tubing.

Size the system piping and circulator to provide the flow needed for the radiant system.

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. 13 page 23.

Maintain a minimum of 6 inches [153 mm] of clearance between units to allow for servicing.

For the space heating piping refer to the applications mentioned in this manual or use recognized design methods.

The burner is not fired because the supply/system water temperature exceeds the setpoint. The domestic circulator continues to operate and the burner will fire again once the supply/system water temperature drops below the setpoint.

The central heating circulator is running to remove heat from the Prestige at the completion of a call.

The domestic hot water circulator is running to remove heat from the Prestige at the completion of a call.

The burner is fired because the freeze protection feature has been activated. Freeze protection will end once the supply/system water temperature is raised to 60ºF [16ºC].

The burner firing rate is being reduced because of an excessive difference between the boiler supply and return temperatures. The firing rate will begin increasing once the temperature difference is less than 45ºF [25ºC].

Start-Up Preparation

SECTION X - Start-Up Preparation

NOTICE

Requirements below must be met for warranty coverage of Prestige heat exchangers. A thorough cleaning of any existing system, using approved heating system cleaning agents is required prior to installation of the Prestige boiler. System should be treated with an approved inhibitor after filling for long term protection.

Check Boiler System Water Chemistry

WARNING

Do not use petroleum-based cleaning or sealing compounds in the boiler system. Damage to seals and gaskets in the system components could occur, resulting in substantial property damage.

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.

Flush Boiler to Remove Sediment

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.

Cleaning of Old Boiler/System:

• Drain the existing system.

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.

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.

• Fill system with fresh water and cleaner, place existing boiler in operation and run all zones.

• Follow manufacturer’s instructions for proper cleaner concentration and proper cleaning time.

• Thoroughly drain and flush system with fresh water after cleaning.

• Install new boiler, fill system with fresh water and proper amount of inhibitor.

• Verify pH and inhibitor level per inhibitor manufacturer’s specs; add inhibitor if necessary.

Cleaning of New Boiler/System:

• Install new boiler and flush system with cleaner water to remove any debris.

• Fill system with fresh water and proper amount of inhibitor.

• Verify pH and inhibitor level per inhibitor manufacturer’s specs; add inhibitor if necessary.

Page 63

Start-Up Preparation

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.

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.

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.

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.

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.

Ensure the concentration of antifreeze to water does not exceed a 50/50 ratio.

WARNING

Unrepaired system leaks will cause continual makeup water to be added to the boiler. Continual makeup water will cause mineral buildup within the heat exchanger, reducing the heat transfer, causing possible heat buildup and eventual heat exchanger failure.

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.

Page 64

Start-Up Preparation

- 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. 36 page 78(PRESTIGE Solo 60) or on Fig. 37 page 79 (PRESTIGE Solo 175/250) or Fig. 38 page 80 (PRESTIGE Solo 399) for location of the LWCO.

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.

Check Thermostat Circuit

- Disconnect the external thermostat wires from the low voltage terminal strip.

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 low voltage terminal strip.

Inspection of Condensate Drain Assembly

1. Inspect and ensure the Condensate Drain Assembly is properly installed as described on page 24 and shown in Fig. 14 on page 25.

2. Remove the plug from the Condensate Drain Assembly and fill with fresh water.

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.

- 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.

SECTION XII - Outdoor Reset Control

The boiler setpoint for a space heating call can be fixed or vary with the outdoor temperature. The use of the outdoor reset function is recommended to optimize boiler efficiency. The default setting of the boiler is for outdoor reset operation. The outdoor reset function must be disabled in Heating EZ Setup after the outdoor sensor is disconnected from the boiler. (See NOTICE on page 64).

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.

9. Mount the sensor enclosure using the screws provided.

Wiring the Sensor

1. Cut a small slit in the seal gasket and route 18 AWG 2-wire cable or similar wire cable through the seal gasket into the enclosure.

Fig. 32: 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 for those buildings, which may 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 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 low voltage terminal strip located inside the boiler enclosure (see boiler wiring diagram, Fig. 19 page 31).

Page 70

External Modulating Control

SECTION XIII - External Modulating

The boiler can directly accept an analog 0-10 VDC signal to control the firing rate from an external modulating boiler controller such as the Optima SCC4.

Wiring the Modulating Controller

Run two 18 gauge wires from the external modulating boiler controller’s 0-10 VDC boiler output to the modulation signal terminals on the low voltage terminal strip inside the boiler. (see boiler wiring diagram, Fig. 19 page 31). This signal will both enable and modulate the boiler. No wiring is required at the thermostat terminals.

NOTICE

Ensure that the polarity of the connections from the external modulating boiler controller to the boiler are correct. Reversed polarity will lead to no response from the boiler.

TriMax Adjustment

The TriMax control must be programmed to accept the 0-10 VDC signal from the external modulating boiler control.

1. Use the Heating EZ Setup function to set the CH Demand to 0-10V Modulation Signal. Reference page 46 for the Heating EZ Setup function.

Programming of External Modulating Control

The external modulating control must be programmed to send 2 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 30 seconds to allow the burner to stabilize before modulating the boiler.

Page 76

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. 14 on page 25.

6. Replace the fill plug on drain assembly.

Check Ventilation Air Openings

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.

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 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.

Verify boiler water pH level is between 6.0 and

8.0.

Check and verify the vent discharge and the combustion air intake are free of debris and obstructions.

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.

Check and verify inhibitor /antifreeze concentration within the boiler water meets inhibitor/antifreeze manuafacturer’s specifications.

If necessary contact a boiler water treatment company for a chemical analysis.

Page 77

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 ignition cable from the ignitor to the TriMax control module.

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.

Inspect the ground wire from the ignitor to the boiler jacket ground terminals.

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.
