To have the best muffling effect, you should install the muffler in the middle of the exhaust pipe. For that reason, we recommend that diesel air heater manufacturers should offer two lengths of the spiral exhaust pipe – short and long. Use two different length exhaust pipes If the distance is too short, the fuel’s pressure coming out of the pump will be too high, resulting in an uneven combustion sound. Also, there may be too much fuel coming out of the fuel pump for it to be fully burned, resulting in carbon buildup. Furthermore, the excess fuel which wasn’t entirely burned may flow out of the diesel heaters through the exhaust port. Many manufacturers recommend you to install a fuel outlet at the bottom of the tank. That will connect it to the fuel delivery line directly—a simple installation method and very easy to use.

A fuel filter’s primary function is to prevent contaminants in the diesel fuel from clogging the oil pump and causing the diesel heater not to work correctly. Location of fuel filter, fuel pump and main engine

Contrary to the point from above, some air heaters manufacturers will provide very long cords. However, that can prove to be problematic too, as sometimes the distance between the heater and the control panel/batter is short. Excess cables are coiled and fixed in place When diesel burns, a small amount of water vapor is produced, which may condense on the exhaust pipe walls, forming droplets. Although this is just a tiny amount, the water droplets will accumulate inside the exhaust pipe if the exhaust port faces upwards.

It’s a little strange but when installing a fuel filter it’s nice because you can easily grab the tank and lift it out.Another option is to use an L-shaped stainless steel mounting plate, which will allow you to mount the forced air heater upright, even when installing it on a boat.

However, if you are selling boat parts or have a boat repair company, you will need to install a forced air heater for your customers, but rotated 90 degrees. If that is the case, you need to pay special attention to the fact that the fuel inlet should be facing upwards when the forced air heater is rotated. That will allow the fuel to burn in the combustion chamber completely. The fuel inlet is upward, the correct installation method on the boat Lastly, the entire exhaust pipe should be slightly tilted downward. That will allow the water droplets to flow out of the diesel heaters through the exhaust pipe. 16. How To Choose The Exhaust Pipe Clamp A diesel heater that’s in good shape is especially important when you’re camping in cold weather and you rely on it to keep you warm. In the new arrangement, this screws to the bottom of the 68mm pipe ( top left photo) to keep insects out (if that was its job), but is not needed at all for silencing. However, customers often have problems as exhaust pipes sometimes come off the top of the diesel heater while the vehicle is running. That is because many diesel heater manufacturers use unthreaded ports. Those don’t have enough friction to keep the exhaust firmly in place in the exhaust port. Smooth interface of ordinary exhaust pipeHowever, problems will occur if the fuel pump is too far away from the main heater too. If the distance is more than 1 meter (3.28 feet(, the fuel pressure will be insufficient. This will again result in uneven combustion, and the heating output will not be as desired. 11. Fuel Filter Installation Considerations

The principal is to get the air fuel ratio right at the lowest speed and the highest speed so the six heat bars stay on with both settings. If you run it too lean it will drop down to five bars which is not optimal.. As you say, the controller adjusts the in between settings on a linear basis. The problem is that some vehicle maintenance companies are not familiar with diesel heaters. They have employees that don’t know how to fit the fuel filter properly, which causes issues.

Steve the tuning of these heaters is important, not very difficult, but seems like a thing of mystery and complication when you read instructions or are a first timer. YouTube has a lot of well intentioned instructional videos that show the process and it’s a good medium for showing rather than describing which in this task is useful. One common mistake when installing the tube of the diesel heater’s cooling air intake systems is that people set it up so that it draws the air from the outside and blows it into the compartment’s interior. The diesel air heater is made of a plastic or aluminum housing and a heater core, and after installing it, you will need to turn the diesel air heater impeller. After installation, turn the impeller by hand
