Anleitung Zusammenfassung


The Riello oil burner has a dela. solenoid valve. The delay solenoid valve provides the same shut down action as the standard solenoid valve, plus on burner start up the delay solenoid valve remains closed for an additional 15 seconds. This allows the burner fan motor to pre-purge the combustion chamber and the oil pump to bring the supply oil pressure up to its set point helping to provide a clean light off. AQUASTAT RELAY CONTROL (provided) The water temperature limit control in the aquastat relay is adjustable and may be set: as low as 140°F so long as return water temperatures to the boiler are no less than 120°F, or as high as 240°F so long as the boiler and heating system have adequate circulation to remove the heat from the boiler otherwise steam may be created in the boiler. Refer back to SYSTEM PIPING section for more information. DRAIN VALVE (provided) The drain valve is a manually operated valve that provides a means of draining all the water from the boiler and heating system. It should be installed in the reducing tee where the return line enters the boiler. CIRCULATOR (provided) Every forced hot water system requires a circulator. A separate circulator or zone valve is required for each zone, if there are two or more zones. The circulator must have the capacity to provide the circulation required by the heating system. The circulator should be connected to the supply main and must be wired into the boiler's electrical system. See the SYSTEM PIPING section for piping configurations with the circulator located on the supply main piping using zone circulators or zone valves. When the piping is arranged with zone circulators and no bypass piping, the circulator provided with the boiler may be used as a zone circulator. Both piping arrangements allow the circulator to pump away from the expansion tank and show how the piping should be arranged to allow the heating system to be easily purged of air. 18 FILLING THE BOILER HOW A HOT WATER SYSTEM OPERATES The entire heating system (boiler, piping, and radiation units) is filled with water. As the water in the boiler is heated, it is circulated from the top of the boiler through the supply main to the radiation units. The cooler water in the radiation units flows back through the return piping through the return main into the boiler. This arrangement provides positive and rapid response to the thermostat. FILLING THE SYSTEM WITH WATER OPTION #1 -This method utilizes the boiler piping as shown in the figure on the previous page. a) Close the main shutoffvalve, isolation valves, and zone valves (if applicable). If bypass piping is installed, also close the two throttling valves. Leave the boiler service shutoffvalve (if installed) and the balancing valves to each heating zone fully open. b) Ooen the following valves in order: the drain valve for power purging, isolating valves before and after the boiler circulator (if applicable), both throttling valves (if applicable), and then open the fill line shutoff valve. Water will fill the bypass piping and push the air through the piping and out the power purging drain valve. When the power purging drain valve runs air free, close the bypass piping throttling valve (leaving the throttling valve to the supply piping f_lly open). c) Next, ooen the isolation valve (or zone valve) to the first zone. Water will fill the piping and push any air out the power purging drain valve. When the power purging drain valve rims air free, close the isolation valve or zone valve). Repeat this procedure for the remaining heating zones. d) Once all zones are filled with water and purged of air, close the power purging drain valve and fill line shut off valve, open the main shutoff valve, and adiust the throttling valves and balancing valves as required. OPTION #2 -Close the air vents on all radiation units. Open the valves to the radiation units. Make sure the boiler drain valve, expansion tank drain cock, and the air bleed screw "on the expansion tank drain fitting are closed. Open the fill valve on the piping to the expansion tank. Open the water inlet to the boiler and leave it open. Open the air vent on the lowest radiation unit. When all the air has escaped and water starts to flow from the vent, close it. Go to the next radiation unit, and repeat this process until finishing with the highest radiation unit. If the heating system has automatic vents, this manual venting is unnecessary but it will speed up the proper filling of the system. If the system is a closed expansion tank system, an automatic fill valve is needed. Leave the automatic fill valve open to refill the system automatically as needed. Note the initial fill pressure on the boiler's temperature / pressure gauge, which should be 10-15 psig. Any lowering of the pressure from its initial fill pressure indicates a loss of water due to leakage. The automatic fill valve should then compensate for this water pressure loss. If it does not, manually open this valve to r...
