If there is a white, powdery substance on the cable that is the result of ignition cable “outgassing,” replace the cable. Typically found in induced draft furnaces, an intermittent pilot ignites the burner gas with a high-voltage spark only when the thermostat calls for heat. If the previous test showed continuity and this one does not, then the module is shorted. Non-lockout — Also called continuous trial for ignition; the system keeps sparking until ignition is established. (Some of the checks can also be applied to direct spark ignition systems.) 6BG1600M Intermittent Pilot Ignition Control Installation Instructions the pilot flame is lost or the call for heat ends. S8600 and S8660 mod-els provide up to 1.0 A pilot and 1.0 A main valve current rating. When replacing, always go to the lesser time if the module with the correct time is not available. During this time, any residual products of combustion will be forced out of the chamber. Use the manufacturer’s sequence of operation, connection wiring diagram, ladder diagram, and any trouble “trees” that are available, along with a good multimeter. The fire in the burners or pilot extinguishes after a slight delay. Burners ignite but turn off after a few seconds. Interpurge — The 30-sec period between trials for ignition, when both the gas valve and igniter source turn off and the inducer is on, allowing unburned gas to escape before the next trial. Intermittent Pilot Ignition System System Overview & Troubleshooting Guide In order to troubleshoot any product it is important to understand the basic operation and functions of that product. 2. Common problems with IP ignition include: The hot surface ignitor (HSI) is the most commonly used electronic ignition system. 800-253-4904 The IntelliFire Plus IPI (intermittent pilot ignition) Ignition System and Wireless Con- trols is a total control system, from the components under the fireplace to the re- mote control in your hand.

These are things that techs should look at as preliminary checks before proceeding with troubleshooting charts and wiring diagrams. Mohd Firdaus Mohd Damanhuri / EyeEm / Getty Images. Lockout — At the end of a trial period, this safely shuts down all systems. McElwain is the owner of Gas Appliance Service Training and Consulting, Warren, RI, which offers servicing and troubleshooting training for gas heat servicers. If you find this, the igniter should be replaced. When you look at the wiring diagram for the equipment, if you see a symbol showing the use of a chassis ground (Figure 2), be careful that you have a good connection. Intermittent Pilot Gas Ignition Control Module is designed to provide easy field replacement of a wide range of intermittent pilot ignition modules manufactured by Honeywell, Robertshaw, Johnson Controls, and others. (For more information, see article on “Circuit Troubleshooting: Use the Right Meter”; The News, April 9, 2001.). Intermittent Pilot Ignition is an electronic system, which uses an electrode to ignite the pilot gas. You can check this by measuring the voltage from each transformer terminal to ground; 24 V = hot side (R); 0 V = ground side (C). Response time — For a thermocouple, about 180 sec; for intermittent ignition systems, 0.8 sec. Visit our updated, This website requires certain cookies to work and uses other cookies to help you have the best experience.

It is used on gas-fired atmospheric furnaces, boilers, and heating appliances. The mystery of intermittent ice production, Troubleshooting the Standing Pilot Safety System, Troubleshooting a flame rectification system. Copyright ©2021. Then the gas valve opens, and the burner gas is ignited by the HSI. Unlike standing pilot designs, which feature a constantly burning pilot light, intermittent designs only light during warming cycles. The larger valve for your main burner is controlled by a wall switch or remote control. Intermittent pilot: Intermittent designs use a small spark to ignite the pilot and burner. This problem can be observed when the intermittent pilot or the direct ignition of the main burners ignite and then extinguish itself right away. Its emphasis is on control familiarization, wiring, troubleshooting, and replacement of controls. HSIs usually cost between $25 and $50, and it's a good idea to keep a spare on hand in case one goes out at night or on the weekend when you can't easily get a new part. It works like a light bulb filament, heating up when electricity is passed through it. When replacing the module, if the time you need is not available, go to the longer prepurge, never the shorter. Make sure the connections are clean and tight. Once the pilot is lit, and the main burner senses the pilot flame (using a flame sensing rod), the main burner ignites. The furnace gas valve for this type of furnace is identifiable with its solenoid designations: MV (main valve), PV (pilot valve), and PV/MV (common). When the main burner is off the pilot is also off. Go from the tip of the igniter to ground — this time you should not have continuity. Sometimes, the pilot will light but not ignite the burner. If you do, it is shorted to ground at some point.

This website requires certain cookies to work and uses other cookies to help you have the best experience. When troubleshooting an Intellifire system, it is important to distinguish it from a standing pilot system. First, the igniter will begin to spark and electricity is sent to the pilot side of the valve to energize the electromagnetic device to open up the pilot … (See sidebar, below.). Control boards are usually located inside the blower compartment of the furnace. The Honeywell Q381 Intermittent Pilot Burners provides pilot flame ignition and sensing for intermittent ignition systems. The electronic ignition system in a gas furnace is a modern development that provides more reliable performance than a standing pilot system, offering energy savings through better furnace efficiency. Furthermore, the next most common problem for furnace troubleshooting that can occur is the flame sensor or flame rectifier. Or, perhaps the spark happens but does not light the pilot. (See Figure 1.) He may be reached at 401-437-0557. Introducing "One Thing": A New Video Series. The resulting flue gases are so cool they can be vented outside via a plastic (PVC) pipe, while the condensed water is run to a floor drain. Not for use on direct vent, induced draft, or power burner equipment. A hot surface ignition system uses electricity. Ignition doesn't occur, and the furnace won't go on. Price $95.41.

Most furnaces with electronic ignition are either conventional induced draft furnaces or high-efficiency condensing furnaces. What is your strategy for vaccinating your employees? Advanced Electric Ignition Systems (Nov. 13 — $150): Course covers power relay vented equipment, relay control centers, integrated furnace and boiler controls, and electronic fan timers. The IPM was replaced last season. IPI constantly monitors ignition, ensures safe functioning and conserves up to $10/month in energy costs. Under the definition of “time trial for ignition,” there is a rule for replacement that says, “You can replace a module with one with a lesser time”; the “prepurge” rule says that when replacing a module, you may go to a longer time; these two rules give some flexibility when replacing controls. If a failure occurs, LED lights on the control board light up in a blinking pattern to indicate a specific failure code. In some furnaces, the HSI also serves as a flame sensor (called local sensing) instead of having a separate sensing rod in the burner flame (remote sensing). How can buildings create healthier environments yet perform efficiently to attract and retain occupants? If the spark will jump across ½ in. It may be necessary to establish a good connection to ground by using a wire with a clamp onto the gas line or equipment chassis and connecting it to the ground terminal of the module. Grainger's got your back. If the system fails to light on the first try because of an open limit, before the second trial, the induced-draft blower and system fan will come on for 180 sec, then start the ignition sequence again. If this check indicates that in fact “R” is 24 V and “C” is 0 V, then the primary polarity is correct. (Note: Hold the igniter cable with insulated pliers and slowly move the connector on the igniter cable toward the high-voltage connection on the module, with the module energized. If it indicates the opposite, then the primary wiring needs to be corrected. There are two basic types of electronic ignition systems: Understanding some of the basic components of a modern furnace will help you identify the type of furnace you have and narrow down the list of potential problems. Here are some of the common causes of HSI failure: Most modern furnaces with electronic ignition systems have an integrated circuit board that controls many sophisticated processes. Figure 1. Bob Formisano is a licensed architect and builder with 30 years of experience in the industry. Self-healing — (Special feature on some integrated fan controls.) The microprocessor provides reliable Larry Campbell is an electrical contractor with 36 years of experience in residential and light commercial electrical wiring. 3. Condensing furnaces use two heat exchangers, where conventional furnaces use only one. One of the first things to check when examining a unit’s ignition operation is the condition of the cable itself. Make sure it’s not touching any metal surfaces. Pilot lights, but the main burner doesn't come on. An intermittent system uses an electric spark instead. Hotel listings are available. The term Intermittent is used because the pilot burner flame is only present when the main burner is operating. Intermittent Pilot An intermittent pilot works by having a small gas line that is just for your system’s pilot light. Hot Surface Ignitors (HSI) This symbol shows the use of a chassis ground. The boards can perform self-diagnostics and provide failure codes, similar to the diagnostic computer in your car.

The ignition cable has electrical continuity, so use a continuity tester or the Ohms scale on a multimeter: From the ground (usually the green wire) terminal on the module, check for continuity to some portion of the boiler or furnace. We therefore include a set of definitions. Continuity check from the tip of the igniter to the ground; in this case there should not be continuity. You should have continuity. Intermittent Pilot Ignition is an electronic system, which uses an electrode to ignite the pilot gas. From the module connection to the igniter cable, an arc should jump at least a 1/2-in. The standing pilot light is the traditional ignition source for most natural gas-fueled combustion heating systems. Once a proper flame is sensed by the flame sensor, the HSI turns off and stays off until the next heating cycle. Remove the igniter cable from the module connection. The igniter is positioned in the flow of gas entering the burners. Resetting Your IntelliFire Plus Ignition System Easily reset your IntelliFire Plus Ignition System by watching the video above. 800-253-4904 Troubleshooting an Intermittent Pilot (IP) Typically found in induced draft furnaces, an intermittent pilot ignites the burner gas with a high-voltage spark only when the thermostat calls for heat. 18 Wiring Diagrams Pgs. When the thermostat calls for heat, 24 volts are sent to the electronic ignition control module, which energizes the furnace blower and other systems and sends 120 volts to the HSI. The following information will assist you through this process. Looking for HONEYWELL Pilot, Intermittent Pilot Burner/igniter (279A01)?

I want to hear from you. When testing the power supply, make sure that the module runs on 24 V. Modern heating equipment is complex enough, so it’s necessary to keep transformer leads identified and properly wired: If connected wrong, the transformer can be burned out, because one side of the transformer is grounded somewhere in the control wiring. TRIAL FOR PILOT IGNITION On every call for heat (system stan). What Is a High-Temperature Limit Switch on a Furnace? The procedures outlined in this article are for checking out all systems that use an intermittent pilot. If the first ignition attempt fails during a normal heating cycle sequence, the control will activate a “self-healing” sequence over the temperature correction cycle before the next trial for ignition. Kozy Heat welcomes your questions while you are at the job site. Our Book https://www.acservicetech.com/the-book In this HVAC Gas Furnace Video I go over how to troubleshoot the single rod spark ignition control module. Shutdown — This means that it will retry without having to interrupt power. The procedures outlined in this article are for checking out all systems that use an intermittent pilot. When the thermostat cues the furnace to start, the gas is allowed to flow from this small pilot gas line. Induced draft furnaces use a small fan to draw the combustion gases from the combustion chamber and out of the house through the flue (chimney). Automatic Ignition Systems ANSI Z21.20 Y8610U Intermittent Pilot Retrofit Kit GENERAL The Y8610U is a complete kit for converting conventional standing pilot systems to intermittent pilot systems. Hot surface ignition: Hot surface ignition systems use … IntelliFire App The IntelliFire app provides smart control for the way you live. The resistance should be about 0.1 ohm. with no trouble at all. If pilot flame is lost, LED, main and pilot valves are turned off for 0.5 seconds and a new trial for ignition sequence will start. The term Intermittent is used because the pilot burner flame is only present when the main burner is operating. Run the test lead up and down the tip, looking for increases in resistance or breaks in continuity (sign of a breakdown). Intermittent Pilot Ignition System Trouble Shooting Guide Contents ... Troubleshooting IPI System Pgs. Tim McElwain will present the following courses at his Training Center in Warren, RI. With this type of furnace, your ignition may not spark at all. The HSI heats up to around 1,800 to 2,500 degrees Fahrenheit and glows red-hot. The S8610U control provides ignition sequence, flame monitoring, and safety shutoff for intermittent pilot central This, combined with recent advances in technology, have led to the rise of intermittent systems.

These modern-day furnaces have either a hot surface ignition or as intermittent pilot system. gap. This system is more reliable and safer than old conventional furnaces, which relied on a natural draft coming in from an opening at the front of the furnace. You should have continuity. The cable on a single-rod system may give you a spark, but will not return a microamp signal due to a break in the cable. The IntelliFire™ Ignition System (IPI) is an advanced intermittent pilot ignition system. BG1600M Intermittent Pilot Ignition Control Application The BG1600M Intermittent Pilot Ignition Control is a safety control designed for indirect burner ignition and supervision, for use with all gases and applicable to gas-fired appliances. In order to understand the principles behind many of the checks, it is important for technicians to understand some of the terms that are used. After the gas is burned to heat the primary heat exchanger, the secondary heat exchanger draws heat out of the hot exhaust gases, cooling them to the point that the water vapor in the exhaust condenses into water. In turn, the pilot flame lights the main burner gas. Condensing furnaces always use hot surface ignition (HSI). Soft lockout — If the burner fails to light after three tries, the system will shut down, wait 60 min (some systems could be longer, up to 3 hrs); it will then go through an ignition sequence again. When the system gets warm enough, the gas begins to flow into the burner and the ignitor will light up. (Occurs only if ignition was not successful during the previous trial.). Kozy Heat welcomes your questions while you are at the job site. This can happen sooner if the oils from your skin get on the element through improper handling, so take care not to touch the element with your bare hands. — “C” on the transformer goes to 24 V (GND); — “C” is connected internally (in the module) to both burner GND and MV/PV. Spark to pilot ignition system with continuous pilot option The spark gap on most systems, from the tip of the igniter to the ground connection, is 1/8 in. IntelliFire™ Plus (IPI Plus) takes this technology to the next level with more safety and memory settings and a programmable wireless remote control. with good intensity, it should be able to jump across 1/8 in. Easy online ordering for the ones who get it done … The combination of electronic ignition, electronic controls, and artificially created draft improves the efficiency of induced draft furnaces over older conventional models. All classes last from 8 a.m. to 4:30 p.m. and include a manual. A spark is present, but the pilot won't light. Intermittent pilot ignition systems feature a control module/board to carry out the ignition system. Induced draft furnaces use either an intermittent pilot (IP) or hot surface ignition (HSI) instead of a standing pilot light. This would cause a no-spark or weak-spark condition. When the main burner is off the pilot is also off. Postpurge — The time after burner operation when the blower continues to run, to force any residual products of combustion from the chamber. Once the switch or remote is used, the ignition sequence begins. Timed trial for ignition — The time a system will try for ignition; this varies with the manufacturer. Most are made from silicon nitride or silicon carbide. In order to narrow down what may be grounded, either the cable or something in the module, remove the cable from the module and check from the connector end to ground; if it shows continuity, the cable is grounded. Check from the tip of the igniter to the connector on the module with it disconnected from the module. The codes are listed in a chart in the owner's manual and usually on a door or access panel on the furnace.
