Chinese Diesel Heater Installation Instructions

The following installation diagram is a brief overview of what your diesel heater installation is going to look like.

Chinese Diesel Heater Installation Instructions

You’ll have a wiring loom, which will connect to your caravan’s battery in order to power the 12 volt heater.

The fuel line will connect to the diesel tank, with the connection of a fuel pump and fuel filter along the way. Note that the angle of the fuel pump (once mounted) needs to be between 15 – 35º.

There will also be an exhaust system and intake pipe, which will both be mounted outside of the caravan.

Chinese Diesel Heater Installation Instructions:

STEPSINSTRUCTIONS
1.Choose install locationSelect a spot to install the diesel heater – under the bed/ dinette seating is the best place. Be sure to check underneath the van that the space is clear and you won’t be cutting into anything.
2.Cut mounting plate holeUse a saw to cut a round hole in the floor of the van for the mounting plate to sit. This is where the pipes & hoses will poke through to the outside of the van.
3.Attach mounting plateUse silicone and screws to attach the mounting plate in place.
4.Install air inlet & outlet ventsCut two holes in the cabinet (under bed or dinette) for the diesel heater’s air inlet & outlet vents to poke through. Attach the ducting & vent casings.
5.Bolt heater to the floorGet under the van and bolt the diesel heater unit to the floor.
6.Attach air intake pipeAttach the air filter & air intake pipe to the bottom of the heater from underneath the van. Secure using brackets.
7.Attach exhaust systemAttach exhaust pipe & muffler to the bottom of the heater underneath the van. Mount muffler with drainage hole angled down to the ground and the exhaust directed away from the caravan.
8.Mount fuel tankMount the fuel tank on the back of the caravan or in the front boot. Install the fuel line nipple in the tank.
9.Mount fuel pump & filterClamp joiners on each end of the fuel pump & fuel filter. Mount both underneath the van with the filter closest to the tank. Both need to be angled between 15 – 35º.
10.Attach fuel lineMeasure 3 lengths of fuel line (tank > filter, filter > pump, pump > heater). Attach with clamps.
11.Connect wiring & monitorInstall the plug-and-play wiring loom & LCD monitor.
12.Seal raw timberSeal off any raw timber underneath the van with paint.

Of course, this is a simplified version for the full diesel heater installation process. If you’re looking for step-by-step instructions with images, check out the link below for the full guide + video.

  1. E8 or E10, hope it helps someone, I found out the breather on the fuel cap was blocked obviously creating a vacuum & therefore no fuel flow. Been fine since I sorted it.

  2. Hey, thanks so much for this it’s incredibly useful & I’ve come back to it a number of times! I am now having issues with my heater, I came back earlier & it was on despite not turning it on / using it in months & now, I physicaly don’t seem to be able to turn it off! Any thoughts, clues or tips hugely appreciated!!!!

    Cheers!

    James

    1. Thanks for your feedback, James. Interestingly, you’re not the first to report the strange diesel heater phenomenon of having it turn on by itself. I would think that cutting the power supply should turn it off (i.e. unplug the fuse or disconnect it from the battery). Let us know how you go!

      1. Yeah it’s a great page & huge help, yes it resolved the issue & having dug a little deeper it would appear that there was an issue because the leisure battery had previously run flat, so back on top of things! Thanks again!

  3. need some advise.purchased two diesel heaters aprox. five years ago one sold with van.installed second heater ordered new remote controller when installed e-07 fault as not compatible .do i need another or can settings be changed.if i order another how do i know it will operate the original heater .THANKS

    1. E-07 is usually a lack of connection between the heater and the LCD monitor rather than the remote. Have you checked for a break in the wiring connection somewhere along the line? Otherwise, if it is a controller issue, you could certainly try a different one to at least rule it out. It can be tricky with the Chinese heaters as there are so many of them and who knows if they’re all compatible with each other or not.

      1. hi, not all remotes will work on the Chinese heaters as the older heaters have different (less educated) mother bords fitted in them, ie: older heaters won’t understand a more modern controller, however, if you swop out the mother board inside the heater along with the newer controller, then they will understand a newer controller! as the heater is really just a Dum lump of aluminium! and it’s the mother board that tells it how it should work!

  4. Great guide thank you. I am having and issue where the heater starts but after 30 seconds the whole unit including the control unit switches off and then comes back on after 15 seconds. I have noticed that the voltage drops on the display before it goes off. Batteries seem good and the rest of the electrical system is working fine. Any advice would be great.

  5. I have a newer vevor unit. It loads up with fuel till it smokes and turns off.

    Some of the units have access to settings like using the 1688 code but mine does not.

    All I have is a alpine setting, which does not lean out the fuel mixture or delivery rate enough.

    Is there a access code for my style of controller, which looks almost the same, or do I have to buy the other style controller and board?

  6. I have two heaters, one 2kw and the other 5kw. on both of them the glow plug goes off after a couple of minutes and it stops. Brand new they run for few hours each. Second time I try to turn them on, they seem to start running but because the glow plug goes off too fast, they do not heat up good enough to ignite on their own and because the glow plug goes off and smokes like hell, until it cools off and stops. So, why the glow plugs goes off that fast?.
    I ‘ll try to power on, the glow plugs, independently, to see what’s gonna happen. Any idea?

    I keep getting e-5 error on my deasel heater I have replaced the heat sensor after about 10 minutes it cuts out . Have checked all the vents they are all clear

    1. Ahh bugger. The fuse should be in your caravan fuse box. Our fuse box was in a little black cabinet underneath the fridge inside the van.

    2. hi Kev, Oh no!, it is very unlikely that any Chinese heaters will have any “”protection diodes”” fitted inside them, so the chances are that you will need to change the mother board inside the heater, and the controller itself. the rest of the heater won’t be affected by the reversed current flow. only the “”smart parts!”” will go “”POP”” you can buy the upgraded mother board for the heater and the new all singing and dancing controller from E-bay and they are easy to fit in, just check that your controller plug is the same as on your heater before you buy it! and fit it the right way around.

  8. Allison Bennett

    Hi we have just bought a Chinese diesel heater and every set of Instructions tell me how to change the temperature yet it doesn’t work. Even at 1.0hz the heater is heating up to 220 degrees C. It melted the pvc connections. I press the function and up button at the same time and nothing happens
    Is my controller faulty? It doesn’t show the battery symbol either. Please help

  9. We’ve been living in our van for a couple of months and run our diesel heater most nights all night for the past 6 weeks
    Now when we start it, there’s an outpoor of white smoke and tonight it sounded like it was struggling to start…I did google that running it on low gets a buildup and needs a good burn out. Is this correct or is it a simple fix/ maintenance procedure
    Thanks in advance

    1. Hi Amanda, yes you’re absolutely right. Running a diesel heater on low for long periods will definitely cause a build up of soot inside the unit. Try running the unit on high for a while to clean it out and burn off that soot. If that doesn’t do the job, you may need to pull the heater apart for a clean and service (success has been found in spraying Brake Cleaner up the exhaust pipe and down into the combustion chamber, after removing the glow plug).

      Blowing white smoke may also indicate not getting enough fuel for ignition, which simply means you need to top up the fuel tank.

    Hi Emma, my diesel heater instructions say that to enter certain functions, I need to be in the non-entry mode, but there is no indication of what that is or how to enter it or get out of it. For example, it says to prime the fuel pump, I need to be in the non-entry mode and then press and hold the OK button and whilst doing so, press the down arrow as well, but all it does is changes (reduces ) a range which was set at 5 before I started which I think is fan speed. This would indicate that it is not in non-entry mode at the moment. The problem is, I cannot seem to enter any other parameters either.

    1. That is odd, I’ve never come across the non-entry mode instruction. What brand of diesel heater have you got? The fact that you’ve got somewhat useful instructions makes me think it possibly not the cheap Chinese one? Is there a manufacturers number or email that you can contact?

    2. My diesel heater stopped working and it shows a non-entry sign at the bottom left corner of the monitor. It is a 12v 2kw heater with model MXR. Did you figure out how to get out of the non-entry ? Would you share that with me?

  11. Thanks a lot I keep coming back. if anybody gets one of those new Handheld red controllers, that pair with the blue wired one, you hold OK to switch it from Chinese to English. Cheers!

        1. I’m not sure. I’ve had a search around and can’t find any info on SN error codes. You could be right with it being connected to the fan settings.
