DANGER

Bacteria can develop in the domestic water system if certain minimum water temperatures are not maintained.

DANGER

HOT WATER CAN SCALD!

Water temperature over 125ºF [52ºC] can cause severe burns instantly or death from scalds.

• Children, disabled and elderly are at highest risk of being scalded.

- Never leave them unattended in or

near shower, bathtub or sink.

- Never allow small children to use a

hot water faucet or draw their own bath.

DANGER

Protection must be taken against excessive pressure!

TO PROTECT AGAINST EXCESSIVE TEMPERATURE AND PRESSURE

• Check if a 150 psi [10 bar] pressure relief valve (field supplied) is installed as recommended for standard installations or a temperature/pressure relief valve for storage tank installations. (DHW side)

• Check if the 30 psi [2 bar] pressure relief valve supplied is installed in the recommended location. (CH side)

• To avoid injury, install the relief devices to comply with local code requirements.

• To avoid any potential scald hazard or if codes require specific water temperatures at the hot water faucet, the installer must:

- Install the factory supplied thermo-

static mixing valve at this appliance and ensure it is working properly

and

- Set the thermostatic mixing valve to

the lowest temperature which satisfies your hot water needs.

- Feed and adjust water temperature

before bathing or showering.

- Water drained from the system drain

valves may be extremely hot.

TO AVOID INJURY:

- Make sure all connections are tight.

- Direct water flow away from any per-

son.

Pre-Installation Items

SECTION I - Pre-Installation Items

Code Compliance

The CHALLENGER is certified to both the Boiler (ANSI Z21.13/CSA 4.9) and Water Heater (ANSI Z21.10.3/CSA4.3) standards.

Due to the CHALLENGER’s unique heat exchanger design which incorporates two independent copper water tube coils; one for space heating and the other for domestic hot water, the CHALLENGER can be installed as a Boiler or Water Heater or both. The unused system does not have to be connected or filled. Parameter 1 (Installation Type) will need to be set accordingly (0= Heat and DHW, 2 = DHW Only and 3 = Heat Only), see page 52 for Setting Parameters.

This appliance 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 appliance 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 10.

- The National Fuel Gas Code NFPA54/ ANSI Z223.1 - Latest edition.

- National Electric Code ANSI/NFPA 70.

- For installations in Canada -“Installation Code for Gas Burning Equipment” CAN/CSA B149.1 Canadian Electrical Code Part 1 CSA C22.1.

- Standards for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1, when required.

NOTICE

The CHALLENGER gas manifold and gas controls meet the safe lighting and other performance requirements as specified in ANSI Z21.13 standard.

Determining Product Location

Before locating the CHALLENGER check for convenient locations to:

- Heating system piping

- Domestic water supply piping

- Venting

- Gas supply piping

- Electrical service

Ensure the appliance location allows the combustion air and 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 CHALLENGER 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 CHALLENGER and its controls are protected from dripping or spraying water during normal operation or service.

SECTION II- Combustion Air and Venting

Combustion Air Contamination

WARNING

If the CHALLENGER 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 appliance and its burner system, resulting in possible severe personal injury, death or substantial property damage.

WARNING

Do not operate a CHALLENGER 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

- 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 area free of these chemicals per SECTION VI 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

Combustion Air and Venting

Ventilation Air Requirements

For installations, involving only the CHALLENGER, in which the minimum service clearances are maintained as listed on page 5, no ventilation openings are required.

Combustion Air and Vent Piping

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

For installations with less than the minimum service clearances involving only the CHALLENGER, the space / enclosure must provide two openings for ventilation. The openings must be sized to provide 1 square inch [6 square centimeters] of free area per 1,000 BTUH [0.3 Kw] of appliance input. The openings shall be placed 12 inches [30.5 cm] from the top of the space and 12 inches [30.5 cm] from the floor of the space.

For installations in which the CHALLENGER 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 CAN/CSA B149.1 for installations in Canada/

The CHALLENGER is certified as Direct Vent (sealed combustion) appliance. A Direct Vent appliance utilizes uncontaminated outdoor air (piped directly to the appliance) for combustion.

NOTICE

Install combustion air and vent pipe as detailed in the CHALLENGER Concentric Vent/Air System Supplement 2010-23 included in the appliance installation envelope. Refer to instructions for parts list and method of installation.

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.

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 CHALLENGER. The input of a CHALLENGER which uses combustion air directly from the outside, is excluded 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.

Combustion Air and Venting

Removal of an Existing Boiler and or Water Heater from a Common Vent System

BEST PRACTICE

When an existing boiler and/or water heater 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 and/or water heater , 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/CSA B149.1, 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/CSA B149.1, 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 CHALLENGER 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.

Additional Limit Control

If a 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 appliance.

- Wiring of the LWCO device to the CHALLENGER should be done in series with the 120 V line voltage into the appliance .

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 200ºF.

- Wiring of the limit device to the CHALLENGER should be done in series with the 120V line voltage into the appliance.

Backflow Preventer

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

Boiler System Piping Applications

BEST PRACTICE

It is required on all piping applications to utilize a primary/secondary piping arrangement. Maintain the minimum boiler flow rate, see Graphs 5-10 on pages 80-82.

Expansion Tank and Makeup Water

Ensure the expansion tank is properly sized for the boiler volume (approximately 1 gallon [4 L]) 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. 5 and Fig. 6 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.

Page 23

Boiler Piping

Closed-Type Expansion Tank

It is recommended to pitch any horizontal piping upwards toward the expansion tank 1 inch per 5 feet [2.5cm / 1.5 M] 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

The CHALLENGER must be supplied with a Central Heating (CH) circulator. The circulator when wired directly to the CHALLENGER will allow for domestic hot water priority and to provide circulation for the freeze protection feature of the boiler control. See Graph 5-10 on page 80-82 for pressure drop and minimum flow rate through the boiler.

Sizing Primary Piping

System Piping - Zone Circulators

Connect the CHALLENGER to the system piping as shown in Fig. 7 page 20 when zoning with zone circulators.

The installer must provide a separate circulator for each zone of space heating.

NOTICE

To ensure an adequate flow rate through the CHALLENGER, the boiler supply and return piping size must be a minimum of 1 inch.

System Piping - Zone Valves

Connect the CHALLENGER to the system piping as shown in Fig. 8 page 20 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 CHALLENGER, the boiler supply and return piping size must be a minimum of 1 inch.

See Fig. 7 and 8, page 20, for recommended piping arrangements based on various applications. Size the piping and system components required in the space heating system, using recognized design methods.

Boiler Piping

System Piping - Radiant Heating

The heat exchanger design of the CHALLENGER 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 highest boiler water supply temperature can be maintained by the CHALLENGER, potentially eliminating the need for a mix system to achieve the desired temperature if all zones of heat are at the same temperature set point.

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

NOTICE

To ensure an adequate flow rate through the CHALLENGER, the boiler supply and return piping size must be a minimum of 1 inch.

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.

Temperature & Pressure (T&P) Relief Valve- Storage Tank Installations

CAUTION

To reduce risk of excessive pressures and temperatures in a storage tank, install temperature and pressure protective equipment required by local codes, but no less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22. This valve must be marked with a maximum working pressure of the water heater.

• A storage tank must be protected with a field supplied T&P relief valve.

• Size the T&P relief valve by the following specifications, unless they conflict with local codes: 3/4” NPT with an AGA Rating of 124,000 BTU/hr.

T&P Relief Valve Discharge Piping

- plugged, reduced or restricted.

- subject to freezing.

WARNING

Do not install any valve between T&P relief valve and storage tank connection or on T&P relief valve discharge piping. Do not plug T&P relief valve or discharge piping. Improper placement and piping of T&P relief valve can cause severe personal injury, death or substantial property damage.

Drain Valves

Drain valves and fittings are field supplied.

Thermal Expansion

If a backflow preventer, check valve or pressure reducing valve is piped on cold water supply piping of water heater, install an expansion tank on cold water supply line to prevent normal thermal expansion from repeatedly forcing open the relief valve.

T&P relief valve discharge piping must be:

- made of material serviceable for temperatures of 250ºF [121ºC] or greater.

- directed so that hot water flows away from all persons.

- directed to a suitable place for disposal.

- installed so as to allow complete draining of the T&P relief valve and discharge line.

T&P relief valve discharge piping must not

- excessively long. Using more than 2 elbows or 15 feet [4.5 m] of piping can reduce discharge capacity.

- directly connected to a drain.

- terminate discharge piping within 6” [152 mm] from drain. Refer to local codes.

be:

CAUTION

Relief valve is not intended for constant duty, such as relief of pressure due to repeated normal system expansion. Correct this condition by installing a properly sized expansion tank in domestic water system. Refer to expansion tank manufacturer’s installation instructions for proper sizing.

The domestic water volume of the CHALLENGER is approximately 0.26 gallons [ 1 l]. Remember to include this volume in sizing of the expansion tank.

Page 30

Domestic Piping

Water Hammer

Dishwashers, clothes washers and fast-closing positive shut-off valves incorporated in the system all contribute to creating water shock. Install a water hammer arrester to prevent damage to pipes and appliances. See device manufacturer’s instructions for application and installation.

Vacuum Breaker - Storage Tank Installations

Installing a vacuum breaker on the inlet of the storage tank will prevent damage to the tank if a negative pressure is developed in the domestic supply line. See manufacturer’s instructions for application and installation of the vacuum breaker.

General Piping Requirements

• For domestic water piping diagrams, see Figs 11 and 12, pages 26 and 27.

BEST PRACTICE

It is recommended to install flush valves as outlined in Fig. 11 and 12, pages 26 and 27 for servicing the domestic coil.

• Use isolation valves to isolate the DHW connections and system components.

• Use dielectric unions or couplings to protect hot and cold water fittings from corrosion when connecting dissimilar materials such as copper and galvanized iron pipe.

• If copper pipe is used for domestic water connections, first solder pipe to a threaded adapter and then screw adapter onto the domestic cold water inlet of the appliance. The domestic cold water inlet contains an internal plastic flow switch which can be damaged by heat from soldering.

NOTICE

Do not apply heat to the domestic cold water inlet when making sweat connections to water heater. Sweat tubing to adapter before fitting adapter to cold water inlet of heater. It is imperative that no heat be applied to the cold water inlet, as it contains a non metallic flow switch.

• When the water supply pressure is higher than 70 psig [4.8 bar], it is recommended to install a pressure reducing valve on cold water supply line to prevent water loss through pressure relief valve.

BEST PRACTICE

It is recommended to install a strainer on the domestic cold water inlet to prevent any nuisance issues with domestic flow switch. An optional lead free, 60 mesh ystrainer is available through Triangle Tube part number CCSTRA01, see Graph 4, page 79 for strainer pressure loss curve.

• All plumbing must meet or exceed all local, state and national plumbing codes.

• Use pipe joint compound or tape suitable for potable water systems.

• Size all piping no smaller than the appliance’s DHW connections.

Thermostatic Mixing Valve

The CHALLENGER is factory supplied with a thermostatic mixing valve with built-in check valve. The mixing valve must be installed as shown in Figs. 9, 11 and 12.

The operating range of the thermostatic mixing is 90ºF [32ºC] to 120ºF [49ºC].

BEST PRACTICE

Additional thermostatic/anti-scald valves should be installed at each hot water faucet, bath and shower outlet.

For applications with a domestic recirculation loop, the recirculation pump should be controlled

Page 31

Domestic Piping

Mixed

by an aquastat. The maximum recommended setting of the aquastat is 10ºF [5ºC] lower than the thermostatic mixing valve setting.

DANGER

For proper operation of the thermostatic mixing valve and to prevent potential scalding hazards, the recirculation loop should be controlled by an aquastat. DO NOT use continuous recirculation.

2. Provide recirculation from the storage tank back to the CHALLENGER using a bronze type circulator. Maximum recommended recirculation flow rate is 1 gpm.

Setting the Thermostatic Mixing Valve

NOTICE

The thermostatic mixing valve controls the outlet hot water temperature delivered to the faucets.

WARNING

POTENTIAL SCALD HAZARD. The mixing valve must be installed on the CHALLENGER. Removal of the mixing valve will create a potential scald hazard resulting in severe personal injury or death.

If any adjustment needs to be made on the valve:

Fig. 9: Mixing Valve Assembly

Recirculation Piping

• Recirculation piping if applicable must be installed in the cold water inlet as shown Figs 11 and 12, page 26 and 27.

• A stainless steel or bronze circulator is recommended and must be controlled by a aquastat. See Graph 3 page 79 for domestic pressure loss.

Storage Tank Installations

For applications requiring large volumes of domestic hot water in a relative short period, the installer may include a storage type tank (see Fig. 12 page 27) in the domestic piping.

The installer must:

1. Relocate the thermostatic mixing valve from the CHALLENGER to the outlet of the storage tank.

- Use a L-Key to remove the set screw securing the knob to the valve.

- Remove the knob and lock ring from the valve.

- Replace the knob and adjust the set temperature of the valve to the desired temperature.

NOTICE

To calibrate the outlet temperature, allow the water to run for approximately 2 minutes and measure the water with a thermometer. To adjust the valve setting, rotate the knob clockwise to decrease the water temperature or counter-clockwise to increase the water temperature.

- Once the desired temperature is achieved, remove the knob and refit the lock ring onto the valve’s “Mix” marking.

- Locate the tab on the inner face of the knob into the retainer in the locking ring. Secure the knob with set screw.

SECTION X - Start-Up Preparation

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 6.5 to 8.5

Flush Boiler and Domestic System to Remove Sediment

The installer must flush the boiler system to remove any sediment to allow proper operation of the CHALLENGER .

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.

Maintain the boiler water pH between 6.5 and

8.5. 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 CHALLENGER or leave the appliance filled until the condition is corrected.

Water Total Hardness Less Than 7 Grains/Gallon

For areas with unusually hard water (total hardness above 7 grains/gallon or 120ppm or mg/l) consult a water treatment company.

Chlorinated Water

Do not use the CHALLENGER to heat a swimming pool or spa directly.

Maintain the chlorine level of the water at levels considered safe for drinking.

Due to the degradation of inhibitors over time, antifreeze fluids must be periodically replaced. Refer to the manufacturer of the antifreeze for additional instructions.

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.

Page 47

Start-Up Preparation

Use of Antifreeze in the Boiler System

WARNING

NEVER use automotive or ethylene glycol antifreeze or undiluted antifreeze in the boiler 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 boiler water volume of the CHALLENGER CC 85 is 0.37 gallons [1.4 l], CC 105 is 0.42 gallons [1.6 l] and CC 125 is 0.50 gallons [1.9 l]. Remember to include this volume in sizing 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.

Filling the Boiler System

1. Close the boiler drain valve located on the bottom of the appliance 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 [0.8 bar]. System pressure will increase when system temperature increases. Operating pressure of the system should never exceed 25 psi [1.7 bar].

4. Purge air and sediment in each zone of the appliance 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.

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.

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.

WARNING

Unrepaired system leaks will cause continual makeup water to be added to the appliance. Continual makeup water could 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 CHALLENGER is provided with a factory installed LWCO device that measures boiler CH system pressure of more than 7 psig [0.5 bar].

- Compare CH system pressure gauge reading to Challenger’s control pressure reading, which can only be viewed when no CH or DHW call is present, adjust pressure accordingly.

Page 48

Start-Up Preparation

Check For Gas Leaks

WARNING

Prior to start-up and during initial operation, smell near the floor and around the appliance 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 appliance 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 appliance is a common problem. Use an isolation relay to prevent voltage from the external circuit entering the CHALLENGER control panel.

- Reconnect the external thermostat

wires to the control terminal strip.

Inspection of Condensate Drain Assembly

1. Inspect and ensure the Condensate Drain Assembly is properly installed as described on page 28 and shown in Fig. 13 on page

29.

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

NOTICE

Check Thermostat Circuit

- Disconnect the external thermostat wires from the control terminal strip, located on the swing out 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.

The condensate drain assembly must be installed on the appliance and filled with water when the CHALLENGER 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 the condensate drain assembly.

SECTION XII - Outdoor Reset Control

The appliance 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 appliance. If an outdoor temperature sensor is connected to the appliance, 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” [5 mm] 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. Remove the sealing nut and sealing gasket from the sensor enclosure.

Fig. 22: 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 CHALLENGER, 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 (close to 120 V wiring) 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 appliance.

5. Connect the sensor wires to the outdoor sensor terminals 9 and 10 on the low voltage X4 connector terminal strip located at the control on the swing out panel (see appliance wiring diagram, Fig. 16 page 34).

Check System Piping

Inspect all piping (water and gas) for leaks and verify that the piping is leak free and properly supported.

Inspect the fittings and components on the appliance and verify they are leak free.

WARNING

Eliminate all boiler leaks. Continual fresh make-up water will reduce the heat exchanger life causing appliance failure. Leaking water may also cause severe property damage to the surrounding area. Inspect the gas supply piping using the procedure outlined on Page 42.

Page 68

Maintenance Procedures

Clean Condensate Drain Assembly

1. Remove the condensate assembly from the appliance.

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. Fill the condensate drain assembly with water.

5. Reassemble the condensate drain assembly onto the appliance.

WARNING

When re-assembling the condensate drain assembly ensure all gaskets are in place and correctly installed. Ensure all associated internal joints are complete, tight and secure. Failure to comply can result in flue gas leakage resulting in severe personal injury, death or substantial property damage.

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.

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.

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 [0.8 bar].

Verify the system pressure, as the appliance operates at high temperature, to ensure the pressure does not exceed 25 psig [1.7 bar]. 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 if present to flush vent. Replace the cap when completed. Ensure vents do not leak, replace any leaking vents.

Removing Internal Flue and Condensate Pan For Inspection

1. Loosen the flue pipe retaining ring as shown in Fig. 23, page 63.

2. Pull up on the flue pipe to disengage from the condensate pan as show in Fig. 24.

3. Pull the flue pipe down and out to disengage from the vent adapter as shown in Fig. 24, page 63.

4. Lift up the condensate pan to disengage from trap.

5. Once the condensate pan is clear of the bottom jacket, rotate it towards the front of the appliance and push down on the rear to disengage from the heat exchanger as shown in Fig. 25, page 63.

- Inspect the flue pipe and condensate

pan for cracks, damage or distortion. Check all gaskets for tears, discoloration or other damage, replace as necessary.

Maintenance Procedures

WARNING

When re-assembling the condensate pan and flue pipe ensure all gaskets are in place and correctly installed. Ensure all associated joints are complete, tight and secure. Failure to comply can result in flue gas leakage resulting in severe personal injury, death or substantial property damage.

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 [0.8 bar]. If tank does not hold a charge pressure, then the membrane is damaged and the tank should be replaced.

Check Relief Valve(s)

Inspect the relief valve(s) and lift the lever to verify flow at least annually or as recommended on the warning tag of the valve.

WARNING

Before manually operating the relief valve(s), 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.

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 igniter to Fig. 26, page 65.

Check Ignition Wiring and Ground Wiring

Inspect the burner wiring from the burner control module to the ground at heat exchanger.

Ensure wiring is in good condition and securely connected.

Check ground continuity of the wiring to the appliance heat exchanger or piping using a continuity meter.

Replace and correct ground wire if ground continuity is not completed and satisfactory.
