Simple enough and plenty of spare parts available when needed. The igniter is positioned in the flow of gas entering the burners. The new water heaters have a flammable vapor sensor, which are possibly too sensitive, and I can not buy them at local dealers, if at all. Then we will surmise based on that why someone would purchase a standing pilot gas ignition system over an electronic ignition system. Once the power is off you can remove the burner door to reveal the ignitor.Turn this to off and leave it off for at least 5 minutes.After this time, turn the ignitor back to the on position and replace the burner door. But now I need to find another new standing pilot 50 gallon replacement. When the power goes out, you can still have hot water. Standing pilot is an older way of igniting a furnace.

The breaker must be ON. Sometimes it is referred to as a safety pilot. The thermocouple device, when heated, provides a small amount of voltage to a pilot solenoid valve. I am very satisfied with Hyde's service. 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). It lights the main burners, rather than a pilot burner. How does electronic ignition work? Lowes, Home Depot, your local plumber, your local hardware store. Another ignition system commonly found on furnaces manufactured in the late 1980s through the 1990s are direct spark ignition systems. Once the electricity has heated up the area to a specified temperature, the gas is released to the burner and lit.

The V-Rod, as are all current Harley-Davidson motorcycles, (and almost all modern motorcycles), has electronic fuel injection and electronic ignition. In some furnaces, the HSI also serves as a flame sensor (called local sensing) instead of having a separatesensing rod in the burner flame (remote sensing). The standing pilot would still give you hot water for baths and other things that would require hot water. Between the standing pilot HW heater and the fireplace keeping the house above 50 deg., my pipes did not freeze and burst. Any reading from 40 to around 200 ohms is good and indicates you have a good ignitor. Do it carefully and install it properly.
