Now you have to remove the outer grill that is available on the wall-mounted heater. Take a screwdriver as it is now time to unscrew the cover that is on the top of the heating unit. You can follow the instruction manual while doing this.

Most probably you are going to find 4 screws which are located at the corner. Find them out and unscrew them one after another. Now remove the cover from the top. In some heaters, you need to pull off the knob first before pulling the cover.

Step 4

Now the next step is detaching the unit. You need to detach the unit and then take it out in a sink and then start cleaning. Make use of a brush to remove the dust particles and other debris.

Get a sponge and dampen it with warm water, use the sponge to clean the front and the backside of that grill thoroughly. This will remove all the dust and dirt stuck on it. During this operation do not use any chemical or flammable cleaning materials, which could damage both the filter and the machine. With a smooth, lint-free fabric, remove the water outlets. Give it time to dry in a less damp environment under the shade.

Easy way to clean a vent free gas heater pilot light

Cleaning a pilot can only be easy when you have all the required types of equipment with you.

It is recommended not to be harsh with the pressure which shouldn’t be more than 100 PSI. There is a fiberglass tube present inside the body of the pilot. There might be a great risk of busting the orifice if you extend the pressure above 100 PSI. this will create a huge flame which won’t be good and you would always want to avoid that.

You’re going to see a little nut here down follow the pilot tube. Loosen the nut up. It should not be very tight and can be separated with a soft twist in some situations. Place the vacuum nozzle at the bottom of the tube and enable the vacuum to suck all particles from the container for a few seconds. If you think that you are done doing it properly then replace the nuts and the tube with the original positions as they were earlier.

Step 6

Once the grill is properly dry you need to make sure you adequately replace it inside the wall-mounted heater and also you need to put the cover back to its original place. Use a screwdriver to tighten the screws to their original place.

Take a lint-free cloth and try to clean the surface of the grill. You are now done cleaning the heater now you can finally turn the electricity and gas connections on and enjoy the heater.

They work very quickly and turn a cold room into a warm and comfortable one in a few minutes. They are also available in electrical versions they are most probably dependant on propane or other natural gases.

Troubleshooting Wall Mounted Gas heaters

Wall-mounted heaters are very useful and they provide warmth to the whole room. Vented room heaters are somewhat similar to water heaters that are present in your home.

The pilot is the same in both of them. It is a flame that keeps on burning throughout as long as the heater is on. There are many features in them for safety and other convenience. As these are appliances they tend to get into troubles and errors.. When they stop working in a proper way you need to check a few things and the best thing about wall-mounted gas heaters is that they can be easily fixed with some littles checkups and steps.

I have mentioned some of the things you can try for troubleshooting your wall mounted gas heaters. These are some of the most common things that happen with a wall-mounted gas heater and how to overcome them.

The pilot doesn’t work (light up)

There might be such situations where you may have noticed that the pilot fails to light up. Even if you have installed the heater correctly and even after following the right steps such a thing can happen.

When such things happen the initial step is to check the supply of gas. The fuel source is to be checked whether it is duly filled. If you have a propane-based gas heater then you need to check the propane tank if there is enough gas or not. If the heating systems use natural gas to run then you need to check the pipeline if there is any kind of deterioration or leakages. If it is such then you need to replace the pipeline.

If everything seems fine then there are possibilities that the aperture might have got blocked. All you need to do is to clear it out. You can take the help of a needle to clear it out. You have to remove all the dust and debris near the combustion chamber. If you can disassemble the tube and blast the air to free the tube from the carbon that has obstructed the tubing, it will be easier.

If the Pilot gets Blown Out

If your pilot is not working correctly or you notice that it is constantly flickering or the flames are getting out on a regular basis then there is a chance that there is something blocking the pipe tube.

There might be several chances that the pipe is getting choked. This is generally due to insects that tried getting space in it. If after cleaning this your heater still doesn’t work then it might be the fault of the thermocouple which might be faulty. It is a small sensor that is positioned next to the pilot which helps to indicate whether the temperature is appropriate or not.

When the thermocouple is defective it won’t let the heater turn on. Normally, it will not stay illuminated whether it is unreliable or too far from the pilot. Under the heater, one potential solution could be sought and moved closer to the pilot. However, it will have to be patched in case the thermo-couple has worn out.

With the pilot being turned on, the burner still does not light up.

This is a common thing and it can happen due to two main reasons they are either the thermostat has some error or the wiring connections are done wrong.

If you notice that the temperature around the thermostat is warm or it isn’t cold enough the thermostat won’t anyway light up. This can be checked by turning up the flame. If you are done with doing this and it still doesn’t work then you can check whether the wiring connections are proper or not. There might be some issue with the wiring that is inside the thermostat box.

If you are unable to find any kind of wiring problems too then there are chances that the gas valve can be the issue here and you can replace it. This thing should be done under expert supervision or you can take help from a professional for this too.

The flame inside the pilot isn’t blue

When the pilot is working normally then the flame that it has is generally blue. If you are having a ventless heater and when the pilot gets light up the flames are yellow then it is an indication that your pilot light is needing cleanup.

When you notice the flame slightly yellow then this is happening just because of the changing of the atmospheric pressure this will certainly result in the shutting off your heater. Your heater will keep shutting on after staying lit for a few minutes.
