why does my patio heater flame out

Patio Heater Won't Stay Lit One common issue that patio heater owners face is keeping their patio heater lit. The typical cause for this is that the pilot light flame has become too far away from the thermocouple. Thus, the
will turn off the patio heater as it tricks the gas value in to thinking that the pilot light is out. Other potential causes are not having enough gas pressure or the pilot light/orifices are more restricted due to corrosion. Another simple cause is that a breeze is blowing just right and is blowing out the pilot light. The Fix There is a way to fix this problem. Making sure the patio heater is БoffБ, sure a pair of pliers to gently squeeze the pilot light and the thermocouple a bit closer. To squeeze the pilot light and sensor-bulb together, remove the top of the heater and the front control panel that covers the pilot light and control knob. Then remove the bracket that holds the pilot light and thermocouple together to that you will get the best access. You may not need to disassemble it as much as you think, but you need to disassemble and very gently squeeze the pilot and thermocouple making sure not to crush it. Now, the pilot light will be very close to the sensor bulb and the patio heater will no longer shut off after a few minutes. Please check out our how to guide and User Manual for easy troubleshooting Another reason that your patio heater won't stay lit also has to do with the. Sometimes the thermocouple gets coated with carbon from the propane. Sometimes using a small tooth file and lightly sanding the thermocouple will help to remove the carbon build up. If the issue is not with the thermocouple the cause of the problem could be a numbers of things. It may be as simple as the gas valve on the propane tank being turned off. Simply turn the gas tank on. Additionally, the propane tank may be empty. A full propane tank is much heavier than an empty propane tank. Take your tank and get it refilled. Yet another reason your patio will not stay lit is that the gas valve orifice is blocked. You should clean the orifice or have it replaced.


Sometimes there is air in the gas line which is blocking propane from getting to the. The solution for this is to purge the gas line. Open the gas line by turning the knob on the propane tank to fully open. Then depress the control knob for two to three minutes. Make sure all gas has cleared before attempted to ignite the patio heater. Loose connections sometime cause problems. Check the to make sure it is tightly connected to the propane tank. Check all other fittings as well. Make sure to use the soap and water test to determine if there are any leaks. sometimes get worn out and fail. You can start your patio heater with a stick lighter. If the heater will ignite with a stick lighter then replace the worn ignition with a new ignition. Sometimes the gas pressure is simply too low. You should replace or refill your propane tank. The problem may also be in the regulator. If the gas is on but there is no gas flow then replace the hose and assembly. If your propane tank is new you will need to purge the air from the gas lines. As described before open the gas line by turning the knob on the propane tank to fully open. Then depress the control knob for two to three minutes. Make sure all gas has cleared before attempting to ignite the patio heater. Patio Heater Flame Is Too Low Sometimes the heater will stay lit but the flame is too low. This could mean that the gas pressure is too low. When the outdoor temperature is less than 40 degrees F and the tank is less than one-quarter full a low flame will result. The Fix Check to make sure the propane tank has enough fuel in it. If not then refill or replace it. б Another potential cause for a low flame is that the gas hose is kinked. Check the gas hose and straighten it. If the hose is damaged in any way then have it replaced. There may also be a blockage in the burner assembly. Thoroughly clean the burner and emitter screen to clear any blockages. Also check the to make sure there is no carbon build-up. If there is, then clean away the carbon. Gas patio heaters can be useful additions to yards or outdoor areas, but they re also quite simple devices from a technological standpoint.


While there are a number of specific mechanisms that allow them to function, overall the only elements that a gas heater needs to work are flame and fuel. Due to their straightforward design, on the rare occasion that one of these heaters doesn t work properly, the checklist of issues for troubleshooting gas is also pretty straightforward. The most common issue you ll experience with one of these is that it simply won t work won't give off light or heat. Here are some basic things to check and change before writing your gas patio heater off as being broken. As with other gas appliances, one obvious reason they fail to work is that there s no gas. Look toward the base of the heater and take out the gas cylinder. If it s light in weight, it may be empty, and you should replace it with a full one. Even if you discover that there was still a small amount of gasoline left in the removed container, a replacement is likely necessary anyway. A minimal amount of gas is required at all times just to create enough pressure to drive the gas burner. That little leftover gas may not have be enough. With a full cylinder in place, turn on the gas, and listen at the burner attempting to hear the sound of the gas arriving. If the patio heater has an electronic ignition system, make sure that there is a spark. If there is a spark but the heater will not light up, try using a lighter or burning spill to light the gas. If you still can t get it to light, verify the following parts are in working order so you can be sure the gas is making it to the burner. WARNING: If it does eventually ignite, stand back as there may be a flash over. This is especially likely if you have been trying to light the gas for a while since there might be a small cloud of gas near the burner. The gas regulator is a connector that joins the gas tank with the gas pipe to be carried up to the burner. Some regulators have a flip switch that prevents the valve in the top of the cylinder from being depressed, effectively acting as an "off" switch.


If you find such a switch on your patio heater, make sure that it s set to the "on" position. It s rare that gas pipe would be blocked but since it s a possibility you should still investigate. Remove the gas pipe from the regulator and from the gas inlet at the top of the heater. This pipe is pressure fitted and held in place by pipe clips. Blow air through the pipe to ensure that it is clear. Either blockages will be blown free or the pipe will be clean to begin with. Disassemble the burner and check for any blockages. Also, check that the burner apertures are set correctly. Beneath each burner is a small chamber in which air and gas are mixed. Make sure all that the gas and air inlets are clear. If you discover any blockages or buildup, clean the burner to remove these obstructions. WARNING: When cleaning the burner, make sure the gas is turned off, remove the gas light mantle, and run pipe cleaners through the burner holes. Most gas patio heaters have a bug screen to keep away insects that are attracted to the flame. If your heater s insect guard becomes too obstructed, it can block the flow of air and smother your flame. Remove the screen and clean it either by blowing on it or with a quick wash and thorough drying. If your heater has a pilot light, the thermocouple may have failed. The thermocouple is usually shaped like an inverted "v" and sits in the flame of the pilot light. The temperature acts on the thermocouple to keep the gas supply to the burner open. A that the thermocouple has broken down is that the pilot light goes out when you try to turn the heater on. are readily available patio heater parts and usually available from stock. If you have carried out all the checks and the heater will still not light, you can repeat all the checks more slowly and carefully or take your heater to a specialist for a service. Any other modifications that do not involve ignition issues on your individual heater will vary according to the manufacturer.
