Main Body

Installation

After dolling the holes necessary for the installation of this heater, it’s important to protect the underlying material from moisture and water damage. If any splintering occurs as the exhaust hole is created, ensure the area is covered with  a sealing paint to prevent water and moisture from getting in.
Main Body

1. When installing a diesel heater in a vehicle, it’s important to consider the location and potential impact on surrounding materials and components. Typically, the heater is mounted in a protected area, such as in the storage compartment  under a bed in a transport truck or under a seat in a passenger vehicle. It can also be installed on walls or in protected compartments outside the operator’s cabin, as long as all regulations and installation instructions are followed. When  choose­ ing a location for the heater, ensure that there is sufficient clearance around the heater, ducting, and exhaust to prevent damage to heat-sensitive materials. Ensure the heater is not exposed to outside elements and that it is properly  enclosed if mounted outside the vehicle cabin. Ensure the mounting surface will allow for a complete seal between the heater and the floor. Avoid exposing the heater to excessive heat or hazardous chemicals and fuels.  Depending on the installation conditions, the acceptable angular range for each side is shown below:
2. Use the mounting plate as a reference to determine the exact positions for each hole. Clearly mark the spot for each hole
3. Use a hole saw and/or power drill to cut through the floor of the vehicle. The holes are necessary  to allow the pipes and hoses to connect and vent outside of the van, but be careful to minimize any other holes or gaps nearby.
4. Apply a generous amount of silicone (not included) around the circumference of the holes and under the mounting plate base. Carefully insert the mounting plate into the holes, ensuring that it sits flat and is centered. Secure the  four corners of the mounting plate to the caravan floor using four of the provided M6 screws and nuts
5. Remove the nuts and washers from the bolts at the bottom of the main body and then mount the main body onto the mounting plate. Get under your vehicle and secure the heater unit to the bracket by replacing the washers and  nuts, making sure it is properly aligned and secure.

Air Inlet & Outlet Vents

1. Remove the nuts and washers from the bolts at the bottom of the main body and then mount the main body onto the mounting plate. Get under your vehicle and secure the heater unit to the bracket by replacing the washers and  nuts, making sure it is properly aligned and secure.
2. Cut the hole using a hole saw and/or power drill.
3. Cut a piece of the air outlet ducting that is just long enough to reach from the diesel heater to the newly cut hole. Secure one encl of the dueling to the outlet vent and insert it into the hole. Use a hose clamp to attach the other end of  the ducting to the diesel heater. If necessary, use the inlet/outlet brackets to secure the ducting to the wall or floor.
4. Fix the vent casing in place using M6 screws and nuts and then attach the outside cover Repeat the process for the air inlet ducting, which will be longer than the outlet ducting.
   Note: The above steps are for reference, and installation may differ depending on the specific setup and location.

I Air Intake Pipe

1. Attach the air filter to the end of the air intake pipe.
2. Connect the air intake pipe to the bottom of the diesel heater using a pipe clamp.
3. Mount the air intake pipe under the vehicle’s floor using a hose clamp
4. Position the pipe so it faces towards the rear of the vehicle to prevent dust buildup during transit.
   

I Exhaust Pipe

1. Use two M6 screws, washers, and nuts to install the exhaust muffler and muffler bracket at a suitable position near the heater. Make sure it is directed away from the vehicle to ensure that the exhaust do not get trapped underneath  the vehicle. Do not point it towards the awning area to avoid inhaling exhaust while sitting outside.
2. Route the exhaust pipe from the heater to the exhaust muffler, using the pipe bend if necessary Fasten it with a pipe clamp. Make sure to position the exhaust pipe on a slight downward slope from the diesel heater unit to allow for any condensation to drain out.

I Fuel Assembly

1. Choose the location for the heater’s dedicated fuel tank. Considering your specific vehicle setup and choose the location that is most suitable in order to maximize stability and minimize spillage. Use the M4 screws or similarly strong  fasteners to secure the fuel tank to the floor or wall through the three holes in the tank body. Use the M4 Washers to prevent any leakage.
2. Open the fuel tank and take out the small accessory bag Determine a location for the fuel pipe and drill a 0.27 in. (7 mm) hole in either the side or bottom of the tank. Thread a piece of wire (not included), e.g. an unbent wire coat  hanger, through the hole and up to the opening at the top of the tank. Place the fuel pipe nipple on the end of the wire at the top and use the wire to guide it through the hole in the bottom Secure the nipple in place with an O-ring  and the fuel pipe nipple nut on the outside of the tank. Connect the fuel pipe and fasten it with fuel pipe clamps . Use fuel pipe extensions if needed.
3. Use the fuel pump bracket to install the fuel filter and fuel pump somewhere under the van and ear the fuel tank. Place the fuel filter closer to the fuel tank. Place the fuel pump closer to the diesel heater, using a fuel pump shock clip  for secure mounting. Ensure that both the filter and pump are angled between 15 and 30 degrees for the best performance.
4. Measure three sections of fuel pipe: firstly from the fuel tank to the fuel filter, secondly from the fuel filter to the fuel pump, and the thirdly from the fuel pump to the diesel heater. Cut the fuel pipe into three separate sections,  according to your needs. Connect the fuel pipe sections between the fuel tank, fuel filter, fuel pump, and diesel heater by attaching the sections at each corresponding point and securing them with jubilee clips.

I Wiring

1. Connect the positive and negative wires to the battery terminals
2. Connect the harness to the diesel heater
3. Connect the wiring to the fuel pump.
4. Connect the wiring to the LED control panel.
5. If necessary, drill a small hole to arrange the wiring to a desired location, such as the fuel pump under the van. To achieve this, remove the connection connector, run the wiring through the hole, and then reconnect the connector It is  recommended to install the LCD monitor display in a convenient location such as on the wall, as it will serve as the control center for operating the diesel heater.

Please note that the above steps are for reference only, and the installation process may vary depending on specific settings and locations.

Maintenance

Poorly ventilated exhaust can be fatal. Follow all ventilation maintenance procedures carefully.

• Periodically inspect the electrical connections, if loose connection found, tighten them if necessary.
• Regularly check the fuel levels of the fuel tank to ensure there is enough diesel to keep the heater running. If fuel level is low, top up the tank with diesel, being careful to avoid overfilling.
• Clean the air filter regularly by removing it from the heater and tapping it gently against a hard surface to remove debris. Use a clean cloth or brush to remove smaller dirt or debris. Finally, reattach the air filter to the heater. It is  recommended to clean the air filter every few months during normal use and more frequently in polluted areas or after heavy use.
• Check the fuel pipe and connections for any signs of leaks, such as fuel spots on the floor or a strong diesel odor. If there are leaks, tighten the connections to prevent further leakage.
  If you are unsure how to tighten, consult your vehicle’s manual or seek assistance from a trained and licensed technician.
• Check the exhaust pipe regularly for blockages, clearing and cleaning the line if needed
• If the heater has not been used for an extended period, it is important to perform a test run before actual using. This will ensure that the heater is functioning properly and that there are no leaks or other issues that could be harmful. To perform a test run, turn on the heater and let it run for a few minutes while observing the fuel and temperature, and exhaust pipe. If everything appears to be working correctly, the heater is ready for use. If you notice any issues,  such as dirty or broken components, clean or replace them as needed. For significant issues, seek assistance from a trained and licensed technician
