Charmglow table top patio heater will not light

I've cleaned the pilot light port. The ignition spark appears to work well. When propane does build up inside the unit and the spark is activated, it will light the gas from the main gas ports, but not the pilot.

If you are using the heater at temperatures below 40 degrees, ther will not be enough gas vapor to run the heater. If the temperature is above 40, look for an obstruction in the gas piping or gas valve itself. There is a small screen on the inlet side of the gas valve that you can inspect if you remove the inlet hose. Make sure you reinstall the hose using a teflon base pipe sealant on the threads.

The yhernocoupler would snuff the pilot if bad. What ignites the overhead burners? and what regulates the overhead gas supply? Look into this. Too much gas will not light as easily as proper balance gas and air. Even more so in a tower type heater.. Turn the gas on low and the pilot should grab it. Good luck

Gas smell when igniting burner.


Hi Jerry

Warning : Gas systems are generally safe but any gas smell should always be investigated by a certified technician as you can never be too safe.

That being said, let me try to assist you as best I can from my experience with gas appliances.

If the smell has been there since you bought the unit, it is probably the pilot you are smelling. Generally, a pilot light is first ignited using either an electro-mechanical switch or using electricity to create a spark.

While ignition is taking place, a small amount of gas is allowed to flow through the ignition pilot nozzle. The spark is meant to ignite the pilot flame. When the pilot flame is lit, a thermocouple is heated up and then allows gas to flow to the main burners. The gas in the main burners then ignites directly from the pilot flame. This is generally how gas burners work but there are many types of equipment and not all of them work on the same principles.

Generally when you smell gas before igniting the main burner but detect no smell after the main burner is on, it has to do with problems in the ignition stage. This could be caused by a number of things but often the ignition probe is the problem. The ignition probe arcs a spark between two probes or between a probe and the burner which is meant to ignite the pilot gas nozzle (or in some cases ignites the main burner directly). Everytime this spark is made, a small amount of carbon forms at the connection point of the sparks. The carbon can build up over time and cause difficulty sparking the ignition of the pilot burner. Spilled food can also cause this or speed up the buildup of carbon.

If the gas can't ignite the pilot immediately, the pilot keeps allowing gas to pass into the air until ignited which is what you could be smelling. Check to see how long after you try to start the burner does it actually ignite. More than a couple of seconds and you will be smelling the gas that escaped without being burned off.

You can try disconnecting the unit from mains power and cleaning the ignition probes on each burner. If the unit has a mechanical starter you should take extra care not activate it during cleaning as you could get a electric shock. Clean the probe with a damp cloth or paper towel and don't use any cleaning agents.

If this does not eliminate the smell you are getting before ignition, you should get a technician to test the unit. The explanation above is also very general as I don't know what specific system you are using so use the explanation given as general knowledge only and get a technician to perform the repairs.

My pilot stays on on my propane furnace but will not light up


The Little Giant units use a Unitrol gas valve very similar to a water heater in the home. #1,urn the Unitrol gas valve to the "PILOT" position to ignite the pilot. Depress the plunger and hold it down then push the spark igniter button until you can see the pilot flame ignite.
You have a lit pilot so this is not a problem for you.
The pilot light stays on continuously by design.
Once the pilot flame is established, you then turn the on/off/pilot valve to the "ON" position and set the thermostat to the desired temperature range., it should then fire its main burner until the desired temperature is reached. Once the temperature is reached, the main burner will shut off and the heater will go into a standby mode with the pilot flame still burning.
If you have turned the pilot valve to on and set the temperature high, it should come on, if not a new gas valve is required, they can be very difficult to replace due to rust.and most cases require a new unit,

Napoleon Fireplace propane Pilot won't light main burner even though gas flows in?


  • I'm going to assume your fireplace has a pilot light.
  • Follow the little holes in the burner that lead to the pilot light.
  • Make sure the pilot flame is pointing directly at the closest burner hole. (adjust if necessary).
  • Often, you will need to sprinkle a layer of "glowing embers" in this area. The embers will help the gas travel to the pilot light and ignite.
  • Always start your propane appliance on "High" never "Low". Cold propane likes to drop to the bottom of the firebox and accumulate until it reaches the pilot (this is called delayed ignition). Keeping it on "high" will help the fuel travel over to the pilot without buildup.

Never drill or try to make the pilot hole larger, this will cause a large flame that cannot be controlled. Check the main parts, first see if you have a spark, next check for leaks, to see how to do a leakage test see patio heater problem solving page. If no leak try changing the thermocouple, these will wear out and can last up to 6 years. Also check the electromagnetic valve that sits inside the gas control valve and if fitted check the tilt switch works. The tilt switch can be shorted out to see if it works.

My furnace wont come on its an automatic pilot so i dont know what the problem is we have enough propane


Hello, Most newer gas furnaces (propane or natural gas) has one of several different types of igniters. The most common one is called a hot surface igniter. This is a ceramic easy to break, glow coil, glowing igniter. Some has a Spark igniter that lights all the burners from a constant spark and some light the burners off a pilot proven /spark igniter. This one sparks then lights a pilot then the burners will come on. In any case if any of these types are not working they could be cracked or broke. Also the inducer draft motor has to be running, the little motor that hooks to the exhaust of the furnace ( if it has one ). This causes the pressure switch to close then the igniter should come on. My suggestion is to call a qualified service tech from your area to assist you. To determine which one of these may be your problem they will have to perform several test. Hope you get going soon. I hope this helped. J
