Product & Safety Information Definitions The following terms are used throughout this manual to bring attention to the presence of potential hazards or important information concerning the product. DANGER NOTICE Indicates the presence of a hazardous situation which, if ignored, will result in death, serious injury or substantial property damage. Indicates special instructions on installation, operation or maintenance, which are important to equipment but not related to personal injury hazards.
Product & Safety Information DANGER WARNING Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system which has been under water. Should overheating occur or the gas supply fails to shut off, turn OFF the manual gas control valve external to the appliance. WARNING WARNING DO NOT add cold make up water when the appliance is hot.
Product & Safety Information • DANGER Protection must be taken against excessive pressure! NOTICE TO PROTECT AGAINST EXCESSIVE TEMPERATURE AND PRESSURE • To avoid injury, install the relief devices to comply with local code requirements. Parameter 1 (Installation Type) must be set to 3 (Heating Only) or 1 (Heating + SMART I.F.W.H.) for all CHALLENGER Solo Boilers (Heat Only, CC85s, CC105s, CC125s and CC150s), see page 44 for setting Parameters.
Pre-Installation Items SECTION I - Pre-Installation Items Determining Product Location Code Compliance Before locating the CHALLENGER check for convenient locations to: - The CHALLENGER is certified to the Boiler (ANSI Z21.13/CSA 4.9) standard. This appliance must be installed in accordance to the following: - All applicable local, state, national and provincial codes, ordinances, regulations and laws.
Pre-Installation Items Boiler Replacement NOTICE If the CHALLENGER is replacing an existing boiler, the following items should be checked and corrected prior to installation: - Boiler piping leaks and corrosion. - Proper location and sizing of the expansion tank on the boiler heating loop. - If applicable, amount and quality of propylene glycol.
Pre-Installation Items Boiler Freeze Protection Feature CAUTION The boiler control has a freeze protection feature. This feature monitors the boiler supply water temperature and responds as follows when no call for heat is present: - 42ºF [6ºC] Boiler circulator and burner are ON. - 50ºF [10ºC] Boiler circulator and burner are OFF. The boiler freeze protection feature is designed to protect the boiler, installed in a primary/secondary piping arrangement.
Combustion Air and Venting SECTION II- Combustion Air and Venting Potential contaminating products 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 could contaminate the air cannot be removed, the combustion air must be repiped and terminated to another location.
Combustion Air and Venting Ventilation Air Requirements Combustion Air and Vent Piping For installations, involving only the CHALLENGER, in which the minimum service clearances are maintained as listed on page 5, no ventilation openings are required. The CHALLENGER requires a Category IV venting system, which is designed for pressurized venting and condensate. The CHALLENGER is certified as Direct Vent (sealed combustion) appliance.
Combustion Air and Venting Removal of an Existing Boiler from a Common Vent System 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. BEST PRACTICE 6.
Combustion Air and Venting Commonwealth of Massachusetts Installations Only For direct-vent appliances, mechanicalvent heating appliances or domestic hot water equipment, where the bottom of the vent terminal and the air intake is installed below four feet above grade the following requirements must be satisfied: 4. A metal or plastic identification plate shall be mounted at the exterior of the building, four feet directly above the location of vent terminal.
Appliance Preparations SECTION III - Appliance Preparations Wall Mounting Installation Shipping and Handling Instructions NOTICE Prior to mounting appliance install piping support bracket according to instructions on page 13. WARNING To avoid damage to gas fitting and piping at bottom of appliance, appliance must be shipped with rear or back of appliance (longest box length) laying down flat.
Appliance Preparations Wall Mounting Guidelines stud centers and ensuring the upper edge of the bracket is away from the wall. 1. The wall-mounting bracket is designed for stud spacing of 12 inch [30.5 cm] or 16 inch [40.6 cm] on centers. For unconventional stud spacing, a solid / secure mounting surface must be provided for installation of the bracket. 3. Level the bracket, while maintaining it’s centering with the studs and use a pencil to mark the location of the mounting slots/holes. 4.
Appliance Preparations Wall Anchors (Solid Wall Only) BEST PRACTICE Apply pipe joint compound to the compression ferrule and compression nut threads of all brass fittings before installation. Install appliance pipes into the fittings until bottom of hex on gas pipe fitting rests against the top of the piping support bracket before tightening any compression nuts. Do not over tighten compression nuts. If fitting leaks loosen compression nut first and then retighten.
Boiler Piping SECTION IV - Boiler Piping - 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 [121ºC] or greater. General Piping Requirements - All plumbing must meet or exceed all local, state and national plumbing codes.

Boiler Piping Additional Limit Control Boiler System Piping Applications If a Low Water Cut Off (LWCO) is required by certain local jurisdictions or when the boiler is installed above the system piping, the following guidelines must be followed: - The LWCO must be designed for water installations, electrode probe-type is recommended. - The LWCO must be installed in a tee connection on the boiler supply piping above the appliance.
Boiler Piping Closed-Type Expansion Tank System Piping - Zone Circulators 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 to the expansion tank to allow air within the system to rise. 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.

Start-Up Preparation SECTION IX - Start-Up Preparation Flush Boiler System to Remove Sediment Check Boiler System Water Chemistry The installer must flush the boiler system to remove any sediment to allow proper operation of the CHALLENGER . WARNING Flush the systems until the water runs clean and is free of sediment. 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.
Start-Up Preparation Use of Antifreeze in the Boiler System 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. 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. 2. Open all system isolation valves. 3.
Start-Up Preparation Check For Gas Leaks NOTICE WARNING 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. 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.
Start-Up Procedures SECTION X - Start-Up Procedures parameters section of the manual starting on page 44 for more information. Final Checks Before Start-Up c Read page 39 through 49 regarding the operation of the CHALLENGER control. c Verify the CHALLENGER 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 69-71. c 3.
