Question about DeLonghi SafeHeat Heater

1 Answer

My Delonghi Propane Heater will not stay lit.

The pilot lights, gas flows, the heat is on, but as soon as I turn and release the starter knob, the pilot goes out and the heat is off.

    As some experts suggested, there was dust in the thermovalve.  I simply sprayed compressed air into the pilot tube.  This cleared the dust and the pilot lighted without a problem and stayed lit.

This sounds strangely like a safety switch problem , ill bet the device that confirms the pilot lite lit before going to main burner has a problem

SOURCE: My deLonghi wall gas heater

The flame of the pilot and main burner are under the control of a thermovalve - it's a device that allows the passage of gas only when heated. This is why when you first start the pilot you must keep the gas button pressed for at least 30 seconds after lighting it - to allow the thermovalve the time to heat up and keep the gas flowing.
If the gas stops flowing when you release the button no matter how long it has been kept pressed before it means that the thermovalve is defective. Since the thermovalve is part of the button mechanism in DeLonghi units the entire button will have to be replaced. By EU law this can be done only by an authorized repair man. On top of that DeLonghi will refuse to work on it if they detect that a security part has been changed by someone else so the best option is to call their closest repair shop and program a visit.

The pilot assembly may be dirty (dust, lint, pet hair) or the Thermocouple has failed. The thermocouple is a safety feature that stops gas from coning out of the pilot, if the pilot suddenly goes out.

If you can disassemble the heater cabinet, you can access all of the inner workings. To clean the pilot assembly use canned compressed air with a straw nozzle (like you clean your computer with). Blow out the pilot tip and all down the pilot assembly. If you see a lot of dust inside the heater cabinet vacuum it out with a vacuum that has a hose and brush attachment. A crevice tool works well too.

After doing all of the above, reassemble the heater cabinet, and try lighting the pilot. Be sure the control knob is right in the pilot position, when you depress it to light the pilot. If it doesn't go all the way in and your don't feel strong pressure pushing back on it, it's not right in the pilot position. Turn it a hair one way and then the other, until you locate it exactly. Light the pilot as you normally would, hold the control knob in for one minute after it lights, then ease off of it slowly. In the Pilot stays lit, let it burn for a minute before turning it to the ON position. After that, you should be back in business.

If the pilot lights and fails to hold, the Thermocouple will need to be replaced.

How do you light the pilot


Turn the gas knob to the pilot setting, press it in and hold it. You should hear gas escaping while in this position. Do not let more than about 10 seconds of gas out at one time as it may pool. Light the pilot while holding the gas knob down for a minute. Release the gas knob (the pilot flame should stay lit) and turn it to the ON position. To make sure the gas heater is working properly, turn up the thermostat and see if the heater heats up. How To Light The Pilot Light On Gas Heater

Pilot light blew out by a fan..I turned the control off..How do I Ignite Please


First locate where to light pilot. You can do this by following thin aluminum colored tubing from control valve to inside heater.In general on top of your gas control valve is a knob. Turn indicator of this knob to pilot and depress knob. This will start gas flow to pilot at end of thin tube. Hold this knob in the depressed position and light pilot. DO NOT release knob for 30 -45 seconds. Then release knob and pilot will remain lit. Then turn knob to on position. If pilot will not stay lit you may need a new thermo coupler, which senses heat from flame to keep pilot gas flow open.
Good luck

Have a dayton 3F405D propane greenhouse heater don't know where to light the pilot light.


Find where the gas line connects to the gas valve on the back of the heater, from the gas valve, follow a small aluminum tube going into the back of the heater. There may be a removable door to access the pilot assembly. If there is no aluminum tube, the unit has electronic ignition and no pilot lite. Turn the gas knob to off, then to pilot. Hold the gas valve in and with a long match or gas grill lighter, light the pilot. Continue to hold the knob in for about 30 seconds. After that, release the knob and check to make sure the pilot stays lit. If so, rotate the knob to ON. The thermostat will kick the burners on.

Pilot light will stay lit as long as i hold down the knob, but when knob released, light goes out....... i have a wall mount model# GWRN30t


Normally when you release the knob it work the same as a two way switch ,which mean gas will stop flowing through the small pilot channel and will flow to large channel where it will continue to burn.
In your case, you have to strip down the regulator switch and look where the gas passage is glogged.

Do not know how to start pilot light


There should be instructions on the inside of the heater access door. Make sure you are comfortable working with gas heaters. Make sure the shutoff valve supplying gas to the heater is on. Turn the gas valve to "pilot", press and hold it while attempting to light the pilot. Once the pilot is lit, continue holding the gas valve knob down for about 30 seconds. The pilot should stay lit once you release the knob. If the pilot stay lit, turn the gas valve to "on". Replace the heater access door and make sure you have proper water flow and attempt to light the heater. If it will not light, or the pilot will not stay on, you will probably have to replace the pilot generator. It provides voltage to run the heater and after time it wears out and produces less and less voltage. A millivolt heater runs on less than one volt so any power loss can be a problem. If you are able, test the pilot generator with a multimeter to see if you are getting at least 500mv when the pilot is on. If not, you should replace the pilot generator or even the entire pilot assembly. Hope this helps...

It sounds like a thermocouple has gone bad. this is a very common problem with gas powered things ie; water heaters, furnaces, hot tubs. The telltale sign is when you release the pilot light button it won't stay lit. This is a safety feature and is relatively inexpensive and easy to repair.

Torpedo heater wont stay lit.


Do you have the serial number or the manufacture date? There are some design changes and I would need to know the year of manufacture to assist accurately. Usually it is a relay or the thermocouple connection that will affect the unit staying lit.

Pilot ligting instructions


many of the newer furnaces don't have a standing pilot. look to see if you have a gas valve with a knob on top that says off pilot and on. look to see if a tube the size of a pencil comes out of the valve and goes down by one of the burners, look to see if there is a little gold piece of metal tubing protruding down to the opening of the larger tube . that is where you place the match. i prefer to use a grill lighter. safer and positive flame. turn knob to off wait 5 minutes for any gas to disipate. be sure your incoming gas valves are all open . usually at the meter and one at the furnace. usually the handle is in line with the pipe when open. from the off position, turn the knob on the furnace gas valve to pilot position and push down on it as you turn. this lets gas flow to the pilot tube by the burner where you have you flame starter lit and waiting. once pilot lights hold down on button for 3 minutes or less. longer is better to be sure the thermocouple senses flame . then gently release the downward pressure and the pilot should stay lit and you gently turn knob to on. if pilot goes out you may have a bad thermocouple. be especially careful if its lp or propane as that gas does not disipate like natural gas and can virtually lay on the floor till ignited. also consider having the heat exchanger checked by a pro with a carbon monoxide detector. they do crack after a few years and can be deadly when they do. good luck
