The B-60 gas valve has instructions on which generator to use. Appliance Repair Training Webinar Recordings. It is used to measure temperature, while a thermostat is used to control it. So, follow this blog post in Linquip to learn the definition of each device as well as the difference between them. Decide how much time you would like to devote to this type of problem and how confident you feel working with gas. When the heat receives the next junction signal of the thermocouple, it starts to produce the electrical output. Step 1: If there is a gas valve at the pilot, turn the valve to the OFF position and wait at least three minutes to let any built-up gas dissipate. @media (max-width: 601px) { Here are the steps you need to follow to replace a thermopile: Make sure to test for gas leaks using the soap method. Visit here to explore more about the differences between thermocouple vs. thermopile in fireplaces clearly. #masthead .hgroup #header-sidebar aside.widget { The thermopile is heated by the pilot flame and is what opens the valve to allow gas flow to the burner. suggestions. If this is not the case then you should test and determine whether the thermopile is good or bad. With a good flame (sorry not a match or aim-n-flame) you will see the voltage climb over 20- 30 seconds to max out around 30 mv. It makes use of the idea of infrared radiation from the thing being measured being absorbed. color: #3b3b3b; } .entry-content .wp-caption { Thermocouple should be encased in the pilot flame. color:#fff; } While you might find that the time investment is worth the money that you saved from a professional repair, you want to ensure that you do not accidentally cause damage to the unit.

Furthermore, while both devices detect radiation, the thermopile does so considerably more precisely and with a higher degree of sensitivity. That holds in a electromagnet/valve to keep the pilot valve open. #masthead .hgroup #header-sidebar aside.widget { All information is provided "AS IS." The kit includes PG9 adapter. lead length for self-generating pilot systems After several moments the camera monitor shows an area darkening that looks like a hairline crack. Finally took off cover and found the hi limit stat had tripped. In fireplaces, thermocouples and thermopiles are generally used to produce power in gas fireplaces and fireplace inserts. How a Thermopile Works? The Eastman thermopile is a replacement part for self-powered gas appliances such as pool and spa heaters, gas furnaces, water heaters, and gas fireplaces. The thermocouple is a thermoelectric instrument, while the thermopile is an instrument that modifies thermal energy into electrical output. #mobile-phone { display:none; } I managed to get the old thermopile out and it looks vastly different than the new pilot generator. When such junctions express differing temperatures, a milliampere DC voltage or a thermo-electric voltage is produced. Hold down the gas controls thermostat knob until the maximum voltage is reached, which may take three minutes or so. All rights reserved. Puts camera on bend at end opposite the burners. They can be used to replace all Robertshaw and similar competitive devices. This item can be returned in its original condition for a full refund or replacement within 30 days of receipt. When it backs, it produces electricity. The most common situation that causes this problem is a bad thermopile. A thermopile in a heating system is an assemblage of several thermocouples that generate roughly 750 mv and activate the main gas valve on a heat call if the pilot is lighted. color: #000000; These thermocouples should be joined in series form with a particular junction placed on the other side of a thermal resistance cover. Types & Working Principle, Types of Thermometers: All You Need to Know, What Is a Digital Potentiometer? } High winds can cause the pilot to be extinguished, which stops thermopile voltage.
