Warning 1 Warning For your safety Do not store or use gasoline or other flammable, combustible or corrosive vapors and liquids in the vicinity of this or any other appliance. Warning: Carefully plan where you install the heater. Correct combustion air supply and flue pipe installation are very important. If a gas appliance is not installed correctly, fatal accidents can result such as carbon monoxide poisoning or fire.
Warning Warning: If a relief valve discharges periodically, this may be due to thermal expansion in a closed water supply system. Contact the water supplier or local plumbing inspector on how to correct this situation. Do not plug the relief valve. FCC: This device complies with Part 15 of the FCC rules.

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 Carefully select the location of the water heater. For your 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 1. Locate the heater where venting, gas and plumbing connections are feasible and convenient. B 2. The hot water lines should be kept short and insulated to save energy.
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 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. Inlet gas particle screen (included) 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 FOR NATURAL GAS Maximum Capacity of pipe in Cubic Feet of Gas per Hour for Gas Pressure of 0.5 Psig or less and a Pressure drop of 0.3” in Water Column (0.75mbar).(Based on a 0.60 Specific Gravity Gas) Btu numbers given in thousands. Follow boxed numbers for piping just one C 950 ES (example: ¾” B.I. Natural Gas pipe for 10 ft (3.0m). will handle 278,000 btu’s (81.5 kWh). For multiple appliances combine the total maximum btu input load and then refer to applicable chart below.
Installation instructions 3.9 Water connections Warning: This heater is not approved for preheated water applications exceeding 140°F (60°C). Warning: In applications where inlet water temperature can exceed 140°F (60ºC), a 3-way valve or mixing valve must be installed before the appliance to prevent water exceeding 140°F (60°C) from entering the appliance. B When facing the heater, the ¾” cold connection is on the bottom right and the hot connection is on the bottom left.
Installation instructions Connecting the pressure relief valve (PRV) A 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 approx.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. 40. By using the design in Fig. 40, there is no recirculation of hot water through the tankless water heater and therefore, does not affect the heat exchanger warranty.
Installation instructions 3.13 Space heating applications Warning: If the set point temperature is above 120°F, precautions should be taken to protect users of potable water from scalding. Warning: Propylene glycol may be used for freeze prevention ONLY on the space heating side of the heat exchanger. Do not use ethylene glycol (automotive antifreeze).

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.boschpro.com for more detailed troubleshooting. For best results, perform each step before proceeding to the next.
Troubleshooting and check all taps for water flow. There should be no water flowing. Any continuous flow of water, small or large, indicates a crossover and must be corrected. Consult a professional plumber for help in correcting a crossover. Failing single lever faucet mixing valves are common causes of plumbing crossovers. 8. Ensure the temperature sensor is making contact and firmly mounted on the hot water pipe. 7.5 Low water flow/pressure 1.
Problem solving 8 Problem solving 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 57). Go to steps two and three to determine flue gas limiter fault and repair it. 2.
Problem solving Display (Flashing) Cause Solution Primary fan rotation too low in operation. 1. Disconnect power supply cord and check wire connection on back side of fan and the connectors on the control board, see Fig. 84, page 65. 2. Check supply voltage. It must be 120VAC and properly grounded. 3. Check venting specifications are met. Long vent lengths, venting with more than three elbows, blocked vent or combination venting may cause this failure. 4.
Problem solving 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. Backflow temperature sensor over 309°F. The appliance will close the burner and lock (non-volatile). 1. Check inlet/outlet vent pipes. 2.
Problem solving 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 43. 6.
