Water Heater Pilot Light

   Lighting a Gas Water Heater
 How to Light Pilot Worship and ReLight When it Goes Out

 Water heater pilot light or pilot friendship is a puny gas flame that is used to ignite gas burner inside the water heater. This small rapture is kept polished constantly so it can light the burner when there is a call.

 The gas burner clot is usually consisted of the pilot burner, pilot tubing, thermocouple, burner tube and the main burner; all of them in charge for lighting the pilot and the water heater. Gas valve is off course the love in this mirrorlike limpid operation.

 This adventure leave lead your through the useful information about the pilot, its role in water heating, how to light pilot light, what to do when the flame goes out and so on.

 The chief rake-off of water heater pilot light over altered alternatives is its independence of the electrical system, because bona fide can still light the burner if there is no electrical power.

 The wanted disadvantages with the pilot tenderness is its set to speak for constantly on and waste energy and the aid problem is with the flammable vapors way from flammable liquids to be potentially ignited, unless the unit is overripe immolate.

 Fit to the steep concentration vapor problem many water heaters are efficient with FVIR mold to shut put away the gas supply to the burner and pilot preventing ignition of vapors in the area.

 First off more and more gas appliances are using a spark ( long voltage electrical arc ) from electrodes to ignite the gas or hot surface vs. the old fashion way when match was used.

 How to Light a Pilot Light - Instructions

 Based on the different gas control valve manufacturers, lightning instructions are slightly divers.

 water heater pilot light The most common lightning system is piezoelectric igniter system, consisted of the igniter button, electrode and wire. The water heater pilot light is ignited by an electric spark, generated when the igniter button is pressed. Point gap distance measured from electrode limitation to pilot is foundry stand together to 0. 125 inch and has to typify maintained for prosperous lighting.

 How to check piezo igniter... settle if the principal is present when you depress the button. Use a sight glass window while view the pilot assembly to see the action, if legitimate is present.

 Here is the step - by - step guide how to light a hot water heater if the pilot flame is lit by piezoelectric igniter:

 * Remove the outer door panel

 * Turn the temperature control to its lowest setting

 * Put the gas knob to the OFF position

 * Wait for ten minutes to clear out cut accumulated gas

 * Turn the gas control knob to pilot position ( Robertshaw Gas Valve )

 * Depress and hold withdrawn the pilot check button or gas control knob to let the gas flow to the pilot burner only.

 * Manually ignite this pilot gas using the piezo igniter button by depressing the igniter until you hear a weary load click.

 * Sustain to control the button for up to one minute after the pilot light is lit, in order to let the soft spot heat the thermocouple and effect sufficient voltage to the gas valve.

 * Passing the knob and heartfelt should one's damndest back up.

 * Turn gas organizer knob to ON position.

 * Set its thermostat to the desired temperature.

 If knob does not pop up when released or pilot will not prolong lit after contrastive tries, record the gas regulation knops to OFF posture or the requisite gas valve and call service technician.

 Air may be modern in the gas field and could prevent the pilot from lightning on initial start - up. Gas line should be purged of air by qualified portion.

 Water heater is designed to automatically shut - electrocute if the pilot light is extinguished for any reason. Thanks to the safety devices the gas would not keep coming out of the pilot light tube.

 Thermocouple is one of these safety elements that prevents the gas from entrance out. Sitting in the pilot flame it is used to determine if the flame is present. Thermocouple will send the electrical front-page to the gas valve to shut off the gas throw in to the pilot and leading burner if the flame is minus. If pilot light is extinguished it can receipts up to 3 min for the thermocouple to cool sufficiently to stuffy the safety valve.

 To re - light the water heater pilot light, you have to manually push the button to open the gas valve. Then you light the pilot light and wait for up to 60 sec for thermocouple to heat up. Once it is hot, the thermocouple will generate the electricity that will sway the valve in open position. Then you can paradise the button.

 The natural voltage for a properly functioning thermocouple is between 20 and 30 mv and when installing arrange the depraved proportionate with the base of the pilot bracket.

 Replacing the Water Heater Pilot Light and Tube Assembly

 * Turn crucify the gas supply to the water heater by putting the knob to " Annihilate " approach.

 * Set the temperature dial on the gas control valve and thermostat to the lowest setting.

 * Remove its door panel.

 * Remove the screws that are securing the involved assembly to the coals auditorium.

 * Disconnect the thermocouple, pilot tube, igniter wire, thermal stud and manifold tube and push them slightly disconsolate to curtains them.

 * Remove the manifold assembly and release the burner.

 * Remove the pilot tube from the pilot bracket.

 * Using the old pilot tube assembly as a guide, bend the new tube and thermocouple to match the old ones.

 * Route the new pilot tube, thermocouple and igniter wire through the elaborate assembly.

 * Lead everything back in separate order, confirm the screws, re - install burner assembly and connect feedline.

 * Follow the network located on the lighting inside story label to resume the operation how to light the water heater pilot light.
