Don't burn brake cleaner. The chemicals can break down to harmful or fatal gases like phosgene or hydrogen chloride

Ok, there's a number of things not ideal in your setup. The fuel filter is the wrong way round and should be close to upright below the pump to eliminate air bubbles and give the pump an easier ride - it will be quieter too. Also check the voltage drop from your battery on startup, if it is dropping below 12v then your glow plug isn't getting hot enough to ensure reliable ignition. If you fix all of these things and still have the same problem i suspect that the glow plug mosfet on the control board has begun to fail and isn't allowing enough power through. I had one to fix last week that was doing the same but didn't respond - turns out the guy had pulled the wiring harness too hard and had broken the copper wire inside the sleeve so that also caused a lack of power to the glow plug. These are wonderful machines and it pays to have a full kit of spares if you rely on one.

if you increase the voltage to the heater to almost 14 volts, your sooting , and error codes will go away. the higher voltage will make the glo plug hotter. thus burn cleaner, less fuel consumption.

Easy way to remove a stubborn mesh screen. Use a coach screw ( pulls equally on screen )

Looking at your fuel line it looks like you are pumping alot of air bubbles to the heater. I suggest you mount it vertically so it will run without air bubbles, lubricate the pump piston better (so it won't prematurely wear out) and run a little quieter.

Thank you for the video.

You might want to try Easy Off Heavy Duty oven cleaner for cleaning your parts if you aren't in a rush. Spray it on and in, and walk away for an hour or two. Wipe it off, or give it a rinse. Much easier.

Good info - Thanks

I wonder if you can run a cleaner through it, like you'd buy fig a diesel truck etc.. I have one of these in my remodel camper, its so nice!

Time for the vevor ultra sonic cleaner next 😊

only thing that's happened to mine is burnt out glow plug, last about a winter season, i just blow through the intake and exhaust with my compressor. great heater for the money £69 when i got mine. i do have to remove the lcd control panel and wrap the screen in a cloth or the cold stops the screen working, but if i for get the cloth or a cold snap drops i have to use a hot air gun to gently heat the screen a minute or two.

You can use other fuels, but only if you adjust the air-fuel ratio properly to match the fuel. A lot of people are on here trying to use waste motor oil, but not changing the air-fuel ratio, and then showing how much it failed. In order to change the air-fuel ratio, you have to get into the secret menu, if you're controller will allow it, some don't. In the secret menu you can change the fan speed and fuel pump speed relative to each other. There are people on KZfaq that explain how to do this. It may not start on the other fuel, so you have to start it and stop it on Diesel or kerosene, or a mix. A lot of people use two tanks and valves for this purpose. Although it's best to have the inexpensive tools, you can typically get the screen out with a lag bolt. Using antisieze on either side of the gaskets will help keep them from sticking for next time. Good luck and have fun with it!

Change the green fuel line that is supplied with some of these heaters...it is not compatible with the pumps and is not fit for purpose.....it flexes too much and causes air bubbles and diminishes the flow of the fuel due to the minute stroke of the pump....Purchase some `hard` nylon type fuel line ( normally white)...you will have far less problems ...especially at higher output settings.

@ 7:05 (& 25:00), there is no gasket between those two pieces?

If you ever have to do this again, I would get a gallon of chemtool carb dip and let the burner sit in that overnight before cleaning. As someone else said, you may have dodged a bullet with the brake cleaner this time, but yeah people have died (slowly and painfully) from welding when even small amounts of brake cleaner are present.

Hi I have the same heater but mine after 2.3 hours of operation the fan starts over speeding and fluctuating the speed up and down even the heater has the same speed setting and finally the heater shuts off and my it gives all the smoke from the combustion chamber on the intake pipe and very strangely, no error code. What do you think

Diesel fuel has a smaller molecule even than gasoline and when you mixed vegetable oil with it, It probably gelled and plugged the screen. If you ever want to find a leak in a gas tank, pour some diesel in it and you will find it if it has one. I hear jet fuel or kerosine works well in these heaters. I wouldn't play around with non flammable solvents with flame if I were you.

Big mistake using a flame with these solvents, certainly asking for trouble. I've plenty of experience in cleaning out soot from Diesel heater steam cleaners, a good wash with alkaline traffic film remover and a pressure washer will remove any debris and it's safe. Dry thoroughly and replace atomiser screen properly so it doesn't block the air intake hole, fit a new glow plug as a matter of routine. Don't mix old veg cooking oil as the flash point is higher and can gum up the atomiser screen. Kerosene is fine but 5% two stoke oil might be a good idea to lubricate the fuel pump or 20% diesel. Have fun

I'm in Newbrunswick, Canada and run a vevor diesel heater to heat my mancave. I find that the filter for the intake that vevor provides is garbage in extreme cold conditions. The filter collects ice crystals in turn, clogging the filter and suffocating the system, causing extreme smoking. I removed the filter and have had no recurring problems. Once and awhile, it is also a good idea to run your heater on high to burn off any soot in the system...

Your problem was trying to burn vegetable oil, doing that blocked up the bleed air hole and it was a downward slope from there. You should run it at full power BEFORE turning it off, not turn it down before turning it off, the more it runs at full power, the less build up you'll get in the burn chamber, that heater was pretty clean other than the starting circuit being gummed up from the veg oil. If you get into the settings, check the max fan speed is 4000 or less, the motor won't last long over 4K rpm, drop the max fuelling a point or two if you reduce the max fan speed to ensure you don't over fuel it. Yes the fuel filter is technically the wrong way round but the mesh is so big that it won't make anydifference, don't worry about the air bubbles in the line, the pump created them, but it keeps pushing fuel in one end si it can only come out the other end, the heater won't suffer for a few bubbles in the line.

If you are filtering your fuel and intake air, you should not be getting such a buildup inside the exchanger. Keep things clean (and don't burn anything but diesel in it) and you will be good to go! So many are burning waste oil or veggie oil mixed with kerosene and other kinds of fuel in those heaters and wondering why the buildup? Well, they're not made to burn that crap! It's a diesel heater made to burn diesel.

Dont forget the magnet on tbe fan needs to contact the bourd so keep the bourd attached

I found a thermostat for these heaters. It will turn the heater on and off not just turn it down. I ordered it yesterday.

I buy a diesel additive (i.e. Kleen-flo) and add a capful to every fuel tank. It significantly reduces the smoke at start-up and also reduces the soot and carbon buildup in and around the burn chamber. It is so effective, I can no longer tell what stage my heater is in by watching the exhaust.

Why is it so dirty? How long has it been running before you cleaned it? Are you filtering your fuel? Just wondering how long I should run mine before I clean it? Thanks for the vid!

Put it in high altitude mode,it will work like a champ,and you will get 30 plus hours out of a gallon of diesel

My unit refused to start after only some 200h. I used it at low power and only pure diesel. How many hours did yours run? And at what setting? Medium/ full power? Or ?

Never see u fit a new gasket??

if I recall other videos right ... to get the screen out you put a screw into it and pull it out....

You talk about problems with it not picking up the fan spinning yeah there's a magnet on the fan and then there's a little sensor and I had the issue of mine becoming loose on the shaft and sliding forward and then the sensor couldn't pick up that the fan was spinning anymore and was shutting down I slid it back so that it was as close as you can get it without it actually rubbing on sensor and put a clamp on fan so that it wouldn't walk off of shaft anymore and haven't touched it in over 4 years

Couple of questions though not yet half way through the video. First…can you provide information on these rebuild kits? And second…would you tell us everything about that snow roof rake!?!?!👍🏻

Oil pump needs to b at 45 degree angle or it will fail every time plus u need to turn MHz down for pump. Keep an eye on the heat oil will burn almost twice as hot as diesel.

That was so painful to watch ...... the removal of the glow plug screen....... a thick bolt with self tapping style thread like a decking bolt and just screw into screen until yo feel it catching and pull bolt out as you still turning it clockwise and the screen will be on the end of the bolt

I'm no expert but it looked to me that the fuel filter is fitted the wrong way

These units are called diesel heaters for a specific reason they run on diesel fuel and kerosene only. Yes you get a bunch of clowns that tell you they will run on just about anything and they will for about 2 days, if you want this thing to run,, use number 1 diesel or kerosene only. Proper installation is a must with these units I see several flaws in yours

Replace that green fuel line with a hard nylon fuel line .

The machine starts at list when is at 12 degrees ....

Pump is not set up correct also after a night on low blast it for 5 to 10 mins to clear it out before stopping it

When u go to high level you get flame out not that it didn’t sense the fan…your issue is your setting are off the pump if running fast it sounds like Also if the cabin is air tight your causing negative pressure …run the intake to suck outside too

You have cleaned the wrong thing its the back filter thats on the chamber thats blocked should be no smoke at all

Amazon will ship them here just not that brand

FYI, once you start digging that screen out, you've got to replace it. Period. Don't touch it unless you plan to replace it. Also the real problem was the clogged air hole in this case. The amount of carbon in there was literally nothing. He could have simply ran the unit on high for 30 minutes to burn that off. You have carbon problems when that burn chamber is literally filled with carbon buildup and chunks. This guy doesn't know what he's talking about at any stage during this video but at least he kinda said so.

Air is getting in from that crappy fuel filter

No gaskets🤔🤔🤔

Every four times you start your diesel heater do 50/50 of kerosene with diesel and it will clean your heater out then running mine for 12 years with no problems

Soak in sea foam, let it do the carbon dissolving.

Holy shit dude! I'm the last to be a safety nazi, I've done plenty of dangerous shit. But man, you lucked out with the brake cleaner. I thought you were doing this outside, then when you started hitting it with the torch, I see you open a door! Just spraying that much methylene chloride, you should have been high as hell. I think they banned it in some country bc a guy died using paint stripper that had methylene chloride in it. General rule of thumb, if it acts like gasoline, but doesn't burn, don't try and burn it! Chlorinated and fluorinated solvents break down with enough heat and make nasty shit like HF, HCl, and phosgene. You seem like a smart dude, but what went through your head thinking its a good idea to pour out large amounts of solvents into a dish in a closed room and then torch it?

Thats a junk unit I can't hold my hand on the side like u did. There's no way it's so hot anfmd that 3 or 4 of 6 I don't need it any higher and I'm in alpine mode

You didn't watch the video of how to remove screen properly

Morel to the story ,just use deisel or kerosene

To cold.

Why are you ALL referring to this item as a " CHEAP CHINESE HEATER " you bought it !!!

Vevor sucks I have 2 and their junk
