Resumen del manual
Every 3-5 years replace component 36 on page 16. The frequency will depend on the mineral content of the water and conditions of use or whenever signs of corrosion appear at the gas and water valve joint. Periodically check that the water inlet filter (#27 on page 16) is clean as well. NOTE: If water valve is removed, be sure to also inspect the o ring seal on the end of the right hand side water pipe before re-installing. Lubricating the o ring with lithium or faucet and valve grease is recommended. Pilot Flame: The pilot flame should burn with a clean, sharp, blue flame and should resemble the diagram in Fig.10. If the flame is soft and yellow, the pilot burner orifice may need to be cleaned or replaced. The pilot flame should be approximately 2 inches long, extending past the flame sensor. If the flame is too small, it will not reach the flame sensor and the burners will not come on. 3mm Correct gap between pilot burner tip and electrode tip Piezo Electrode Flame sensor Fig. 10 - Characteristic Pilot Flame (Pilot assembly shown without pilot hood) To clean the pilot burner and/ or the pilot orifice : Turn off the gas to the unit. Set the On/Off switch to Off (position ). Remove the cover of the heater. To do so, pull off the temperature adjustment knob and unscrew and remove the plastic collar. Pull main cover out toward you and lift up and out. The pilot orifice should be cleaned or replaced. Do not enlarge the orifice. Do not use any wire or sharp object to clean orifices. Natural gas orifices are large enough that you can usually clean them by blowing through them. LP orifices, on the other hand, are too small to clean and should be replaced. To access the pilot orifice, remove 2 screws holding pilot assembly in place. Then loosen compression fittings to expose pilot orifice. PILOT ORIFICE Fig. 11 - Pilot burner with pilot orifice (Pilot assembly shown without pilot hood) Main Burner Flames: The main burner flames should be blue, with a more intense blue cone in the center core. Yellow flames could be a sign of wrong size gas orifices or dirty burners, or a blockage on the heat exchangers fins. If some burners have yellow flames while others have good flames, it is likely that dust, lint or spider webs have partially clogged the burner venturis. To clean the burners, contact a gas service person. Mineral Scale Build-up: The AquaStar heater, when operated at lower temperature settings, does not accumulate mineral build-up. If however, the heater is used at the higher temperature settings and the water has a high mineral content, periodic descaling may be necessary. The heating coils should be flushed with a descaling solution. The descaling is done only to the heat exchanger. The chemicals will damage the hydro-generator and other parts. Consult your dealer or Controlled Energy for instructions. TROUBLE SHOOTING Introduction The AquaStar 125HX burners are activated by a water flow valve. Numerous water related problems can cause this water valve to malfunction such as: Insufficient water flow volume to activate the burners at its minimum flow requirement; Dirt in the water flow valve causing it to malfunction; Sediment build-up in faucet aerators, or shower heads; Uneven pressures between cold and hot. (with single lever faucets) Plumbing cross overs. These water flow related problems can cause the heater to deliver less than its full output, or to fail to ignite or to shut down completely. Piezo 6 720 606 804 (02.10) Problems are stated in upper case, bold face. Most common causes for the problems follow in order of likelihood. The suggested solutions require that the cover be taken off. To do this, remove incandescent particle tray, pull off the temperature adjustment knob and unscrew and remove the plastic collar. Pull main cover out toward you and lift up and out. NO SPARK AT THE PILOT 1. On/Off switch is not ”On” (Position ). The On/Off switch is located behind the flipdown cover plate on the front panel strip. See fig. 9. 2. Cross over in water lines To confirm there is no cross-over in the plumbing, shut off the cold water supply to the AquaStar and open all hot water faucets. There should not be any water flowing at any faucets. Water running is a sign of a plumbing crossover. Consult your plumber. 3. Water flow is not sufficient to activate heater. Water flow rate at faucet is below minimum flow needed to activate heater. When temperature adjustment knob is turned all the way clockwise, the AquaStar model 125HX requires 1/2 gallon per minute flow to activate the heater. As a reference, this is a flow which would fill a quart jar in 30 seconds. If the temperature adjustment knob is turned fully counterclockwise, a flow rate of 1.1 gallons/minute is required to activate the heater. The red LED light (located behind the coverplate on the front panel) flashes when the water flow is not enough. 4. Water inlet filter is clogged Water flow is restricted, preventing needed flow to activate heater. Cle...
