Installation instructions Attention residents of the Commonwealth of Massachusetts: In the Commonwealth of Massachusetts the following regulation went into effect on 12/30/2005: signage installed in accordance with the provisions of 248 CMR 5.08(2)(a)1 through 4.
Installation instructions 3.4 Combustion air requirements Warning: In areas where outside temperatures routinely come close to freezing, sealed combustion operation is required. Use a concentric termination or separate terminations for combustion and vent, which must be installed on the same wall or roof surface, however never facing the direction of prevailing winds. Failure to do so may result in heat exchanger freezing up and bursting. This failure is not covered under the manufacturer's warranty.
Installation instructions 3.5 Proper location for installing your heater 3.7 Warning: before starting installation: Carefully select the location of the water heater. For safety and for proper heater operation, you must provide combustion air to the heater and a proper exhaust vent system. Follow the guidelines below: B Check that there are no loose or damaged parts inside the appliance B Confirm that the gas type of the heater matches the gas supply you will be connecting to the heater, See Fig.
Installation instructions 3.8 Gas piping & connections Before connecting the gas supply, check the rating plate on the right side of the heater to be sure that the heater is rated for the same gas to which it will be connected. In the United States: The installation must conform with local codes or, in the absence of local codes, the National Fuel Gas Code ANSI Z223.1/NFPA 54. In Canada: The Installation must conform to CGA B149 INSTALLATION CODES and/or local installation codes.
Installation instructions Minimum 3” Gas supply Cap Inlet gas particle screen (included) Fig. 29 Gas connection Once connections are made, check for gas leaks at all joints. Apply some gas leak detection solution to all gas fittings. Bubbles are a sign of a leak. A combustible gas detector may also be used to detect for leaks. Gas piping Fig. 30 Danger: If you have a leak, shut off the gas. Tighten appropriate fittings to stop leak. Turn the gas on and check again with a gas leak detection solution.

Installation instructions 3.9 Water connections Warning: This heater is not approved for preheated water supply exceeding 140°F (60°C). B When facing the heater, the ¾" cold connection is on the bottom right and the hot connection is on the bottom left. Centrally locating the water heater is recommended to keep hot water distribution times even throughout the structure.
Installation instructions Connecting the pressure relief valve (PRV) The listed pressure relief valve must be installed at the time of installation. No valve is to be placed between the PRV and the heater. No reducing coupling or other restriction may be installed in the discharge line. The discharge line must be a minimum of 4" above a drain and installed such that it allows complete drainage of both the PRV and the line. The discharge line must be placed where it will not cause any damage.
Installation instructions 3.11 Filling the condensate trap The condensate trap can be filled before or after connecting the vent pipe. B Fill the condensate trap by pouring approximately 14 oz. (400ml) of water into the top of the drain tube. To avoid damage to the appliance use a funnel in this operation, see Fig. 37, page 31.
Installation instructions 3.12 Domestic hot water recirculation Although recirculation directly through the tankless water heater is allowed, temperature stability is improved by recirculating through a mini-tank as shown in Fig. 35. By using the design in Fig. 35, there is no recirculation of hot water through the tankless water heater and therefore, does not affect the heat exchanger warranty of 15 years.
Installation instructions 3.13 Space heating applications Warning: Ensure the primary pump is properly sized to provide adequate flow for the system heat load. Warning: If the set point temperature is above 120°F, precautions should be taken to protect users of potable water from scalding. For Pump sizing please refer to the pressure drop curves, Fig. 41.

Troubleshooting 7 Troubleshooting Warning: If you are unable to perform the tasks listed below, or need additional assistance please contact your original installer or a licensed gas technician. 7.1 Introduction Many of the questions customers ask regarding operation of this unit can be answered by following the troubleshooting steps as outlined below. Visit our web site at www.bosch-climate.us for more detailed troubleshooting. For best results, perform each step before proceeding to the next.
Troubleshooting Contact your original installer or a local certified gas technician to obtain this reading. 7. Cold water is mixing into the hot water lines (plumbing crossover). A plumbing crossover can unintentionally mix cold water with the hot water leaving the heater. The end result is a cooler water temperature than desired. To check for a plumbing crossover, shut off the cold water supply to the water heater. Then open all of the hot water taps served by the heater.
Troubleshooting specifications in Section 3.4, page 24 Combustion Air Requirements. 4. Cross contamination. Ensure that intake and exhaust terminations maintain required clearances as stated in chapter 3.3, page 10. Cross contamination between intake and exhaust may cause unstable burner flames and noise. 5. Lack of gas pressure. Inadequate gas pressure will cause the fuel-to-air mixture (CO2) to be out of adjustment. This will result in unstable burner flames and noise.
Error codes 8 Error codes 8.1 Error code diagnostics i To remove error code from the display, press the reset button. Display (Flashing) Cause Solution Fault in the flue gas limiter. Temperature above 230°F (110°C) inside the cabinet. 1. Check continuity of the flue gas limiter (see Fig. 77, page 58). Go to steps two and three to determine flue gas limiter fault and repair it. 2.
Error codes Display (Flashing) Cause Solution Primary fan rotation too low in operation. 1. Reset errors, disconnect power supply cord and check wire connection on back side of fan and the connectors on the control board, see Fig. 84, page 66. 2. Check supply voltage. It must be 120VAC and properly grounded. 3. Check that venting meets installation specifications. Long vent lengths, venting with more than three elbows, blocked vent or combination venting may cause this failure. 4.
Error codes Display Cause Solution Exhaust temperature sensor - the appliance will close the burner and lock if it gets over 194°F; (only applied for condensing unit). 1. Clean and check heat exchanger. 2. Clean and check condensing heat exchanger. 3. Reduce maximum power (chapter 3.14, page 35). 4. Reduce water temperature setting. Backflow temperature sensor over 309°F. The appliance will close the burner and lock (non-volatile). 1. Check inlet/outlet vent pipes. 2.
Error codes Display Cause Solution Ionization failure during operation. 1. Check gas type, Fig. 2, page 6. 2. Check three wire connections to ignition group on the lower front of the heat exchanger are secure. 3. Verify that venting specifications are met. Improper venting may cause premature failure of the flame sensor rod. See chapter 3.3, page 10. 4. Check gas pressure. See chapter 3.14, page 35. 5. Check and adjust CO2 readings. See chapter 6.5, page 42. 6.
