psig). The water heater, including the pressure regulator and manual valve provided with it, must not be operated at gas supply pressures in excess of 3,45 KPa (. psig).If overpressure has occurred such as through improper testing of the gas lines or emergency malfunction of the supply system, the gas valve and regulator must be checked for safe operation. Make sure that the outside vent valves are protected against blockage. These are part of the gas supply system, not the water heater. Vent blockage may occur during ice storms. PROPANE SUPPLY Figure 4 Where used with propane (LP gas) a separate correct propane regulator must be installed at propane tank to deliver propane to BOSCH regulator at 11’’ W.C. pressure. OPERATING INSTRUCTIONS WARNING If the water heater has been damaged or exposed to flooding, fire, or sooting do not operate the heater until all corrective steps have been taken by a qualified serviceman. FILLING Before proceeding with operation of the water heater make sure that the system is filled with water. -Turn the water flow selector handle clockwise ( ) against stop. -Open all hot water faucets connected to the W125K…to allow trapped air to escape from heater and piping. -Close all faucets, once water flows freely and all air has escaped from system. -The water heater is now ready to be lit. SERVICE HINT The screen (strainer) in the water valve, located in inlet of the water valve, may require occasional cleaning due the foreign material in the water supply. This will restrict the flow of water and may affect heater operation and prolong filling time. To inspect the screen, close the cold water supply valve ahead of the heater, disconnected cold water line from inlet of water valve and remove screen from inlet. Clean if required, replace screen in inlet to water valve, reconnected and open cold water supply valve. LIGHTING Light the water heater in accordance with the instructions on the Lighting and Operating Plate on the water heater. For your convenience, the instructions are repeated below. LIGHTING INSTRUCTIONS 1. STOP! Read the safety information, (first section) of the Lighting Instruction Plate on the cover. 2. The main manual gas valve must be closed (turn valve handle clockwise , see fig. below ) and the gas valve button slide to the far left under the OFF mark. 3. Wait five (5) minutes to clear out any gas. If you smell gas, stop! Follow ‘’B’’ in the safety information above on this label. If you don’t smell gas, go to next step. 4. The pilot burner is located behind the peephole located in the front center of the jacket directly below this instruction plate. 5. Slide the gas valve button to right to pilot position ( ) and open main manual gas valve (by turning valve handle counterclockwise ). 6. Fully depress gas valve button ( ) and light pilot by pushing pilot igniter button ( ) 7. Observe pilot flame through peephole. The gas valve button should be held down at least 10 seconds with pilot burning. When the gas valve button is released the pilot should continue to born. -If the gas valve button does not pop up when released stop and immediately call your service technician or gas supplier. - If the pilot will not stay lit after several tries, slide the gas valve button to the left. Under the OFF ( ) mark, turn the manual gas valve to the off position and call your service technician or gas supplier. 8. Slide gas valve button to the right to the ON position ( ) the heater will now fire when water is drawn at a rate greater than the threshold flow rate (see manual). Note: If main burner should fait to ignite make sure pilot is burning. If not repeat lighting procedure steps 1 through 8. TO TURN OFF GAS TO APPLIANCE 1. Close main manual gas valve and slide the gas valve button to the OFF position. PEEPHOLE GAS VALVE BUTTON PILOT IGNITOR BUTTON WATER FLOW SELECTOR PRESSURE REGULATION The pressure regulator supplied with the water heater is adjusted to operate on the gas specified on the rating plate and: -in Canada, is factory preset to deliver gas at the high altitude pressure setting listed on the rating plate and as shown below. -in the U.S., is factory preset to deliver gas at the standard altitude setting listed on the rating plate and as shown below. The pressure setting of the gas pressure regulator should be checked at installation to assure that the setting is correct for the gas being used and the altitude at which the appliance is installed. See rating plate on the unit, or the chart below for proper settings. In Canada for a heater being installed at standard altitude (0- 2.000 ft. elevation) the manifold pressure should be reset at installation to value shown on the rating plate, or chart below for standard altitude. The gas pressures specified below refer to flow pressure taken at the pressure tap in the gas inlet pipe (just above pressure regulator, figure 5) while the heater is operating at full input.
