Manual (hand-powered) 2. Millivolt (self-powered) 3. Electronic (externally powered) ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 5 overview ___________________________________ Manual Valves Require the control valve to be turned on by hand or may not use a flame detection for safety (pilot light with thermocouple) ___________________________________ May include a thermostatic function (thermostat bulb) to turn burner on and off with changing room temperature. ___________________________________ May ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 6 overview Millivolt valves Self-powered system Require a continuous pilot and thermopile The thermopile supplies enough voltage (about a 1/2 volt) to energize a coil inside the valve to open The millivolt system allows a separate control device, such as a wall thermostat, wireless remote control or wall switch to operate the appliance ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 7 overview ___________________________________ Electronic valves By definition, electronic valves use an external power source, DC or AC be remote controlled without a separate control module (latchtap) May include flame height operation (vari-tap or Maxitrol GV34) Some systems also include electronic ignition, using an automatic heat source instead of a standing pilot for burner ignition. ___________________________________ May ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 8 overview ___________________________________ Electronic Ignition There are several types of electronic ignition, categorized by the ignitor type. 1. I.P.I. – intermittent pilot ignition Spark-to-pilot ignition – hot surface ignition (glow plug) H.W.I. – hot wire ignition (like H.S.I.) ___________________________________ ___________________________________ H.S.I. 2. D.S.I. – direct spark ignition (Direct ignition might also be HSI or HWI) ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 9 ___________________________________ Electronic Ignition History ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 10 history ___________________________________ Electronic Ignition Issues Early systems used furnace technology – DSI or HSI & AC Early systems were much higher cost compared to standing pilot systems - $500+ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 11 history ___________________________________ Electronic Ignition Problems Early systems not understood by many of the service people in the hearth industry Early systems prone to some heat transfer problems ___________________________________ ___________________________________ ___________________________________ (things melted) ___________________________________ ___________________________________ ___________________________________ Slide 12 history ___________________________________ Electronic Ignition Problems Early systems had peculiarities (example: polarity sensitive) Early systems leaned towards hot surface ignition – trouble prone in the hearth environment ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 13 history Electronic Ignition Past only in markets where law prohibited standing pilots (decorative category) Not all manufacturers produced them Early systems were dependent on 110 VAC Systems ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 14 ___________________________________ ___________________________________ Today’s Electronic Ignition ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 15 today ___________________________________ Current Day Electronic Ignition Most manufacturers are using some form of electronic ignition There is a better understanding of systems among hearth professionals Intermittent pilot types are most prevalent ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 16 today ___________________________________ Current Day Electronic Ignition AC with battery back up is available Total battery operation is available Battery with manual override is available (thermocouple) AC with battery backup & thermopile is available ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 17 tomorrow ___________________________________ The Future of Electronic Ignition Consumer demand – energy & cost savings – standing pilot will burn $30+/per month when using propane (about a litre per day) Energy regulations may require electronic ignition in the near future Convenience – no bending down to light pilot ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 18 today ___________________________________ Current Electronic Ignition Gas Valves Control Center Ignition Volts Honeywell Honeywell I.P.I 24 AC VCG Ambient I.P.I 6VDC/batt/TP Maxitrol Maxitrol I.P.I/Manual 6VDC Dexen Dexen I.P.I 3VAC/DC batt American Flame SkyTech I.P.I. 6VDC/batt SIT SIT I.P.I. 7VDC/6VDC ___________________________________ ___________________________________ ___________________________________ . . . and more ___________________________________ ___________________________________ ___________________________________ Slide 19 technical Intermittent Pilot Ignition or Spark-to-Pilot ignition Also referred to as I.P.I.

___________________________________ Slide 86 troubleshooting Operational issues In the case of an aggressive vertical vent, the pilot will light, proof, and the burner will light, but the oxygen will be immediately consumed, so the main burner and pilot will weaken quickly and the flame sense will be lost at the pilot. It will retry a few times, but eventually it will go into lockout and will have to be reset. ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 87 troubleshooting Helpful Tip If the customer prefers not to leave the pilot on continuously, turning the pilot on 10-15 minutes before lighting the main burner will prime the vent system and alleviate some of the glass condensation issues. ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 88 troubleshooting Gas valve/control damage High voltage (lightning, jumper wires) High Pressure High water (flooded) High temperature (no shield) ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 89 technical ___________________________________ Ignition Control Damage ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 90 technical ___________________________________ Digital multimeter Need Direct Current volts. down to millivolts(tc, tp) Need Alternating Current volts (house current, transformers) Need Ohms (resistance) Continuity is nice Rarely need Amps (current), except for HSI systems ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ ___________________________________ Slide 91 ___________________________________ troubleshooting Isn’t technology great?
