Mules, I did a few posts on another group listing the common errors folks make installing. Here you go:
Latest info for you after testing my new Vevor.
I just finished starting and testing my new 5kw Vevor diesel heater, all in one vertical. Works fantastic! Took 5 min to set up, I am test running it now going on 3 hrs to see fuel burn.
Good bluetooth app, good control head, and good remote control. Running great off my Pecron e1500LFP power station, using the 30A xt60 port. Runs from 9w min setting level1, to 65W on max level 10.
I watched 60 videos on these, and 90% of them had incorrect installs that would cause errors! Pay attention to these key points for trouble free, apparently:
1. Exhaust pipe must be horizontal to downward so moisture condensation flows out. So many people say, "exhaust is too hot for moisture, I won't worry about it," and get error code.
2. Total bends in exhaust must be less than 270 degrees. Less is better, minimize combustion air loop restrictions.
3. Input Amps, needs 12v and 15A. It doesn't use 15A i.e. 180W, but will use 120W on startup, so 10 amp. If it's power draw of 10A on start is restricted, say by plugging it into a power station port that doesn't really deliver 10A, it will throw an error.
4. Input Voltage, needs 12v. If power station isn't regulated to >12v, most good ones are 12.7 or 12.8, heater can throw an error.
5. Voltage drop from too small wires, too long wire, or bad connections!! Most common error I see thrown. The supplied power cable is long and juuuust ok for 12v and 12A if no other losses. But if you use a crappy cigarette lighter plug on it, you can get errors due to voltage drop/loss from long small wire and poor connection. The best practice is cut the wire to minimum length needed. If long power supply needed, replace wire with larger gauge. Hard wire it to a DC fuse block with good connection, or use xt60 or Anderson plugs that are both good for 15A and don't lose voltage. The 5521 dc barrel plugs many power stations use for output can drop voltage too much during its 10-12A, 120 to 140W, startup cycle. Same with the cigarette lighter outputs, often can't flow the 120w startup power without voltage drop that throws an error. You NEED A 15A DC Output or it is likely to fail! Some folks with 10A max outputs have successfully used an AC to DC charger to get good 12.8 volts.
6. These are intended to be installed INSIDE the heated area, and are safe, proven by a million trucks using them. Recirculating and reheating interior air vs cold outside air, is the correct way.
There are hundreds of vids on diesel heaters out there, but yet these mistakes are made again and again, even by my favorite overlander youtubers...
