A properly installed exhaust system is very important for any food trailer, mobile food truck trailer, or concession trailer with cooking equipment inside. The American-style chimney and rooftop exhaust fan help remove smoke, heat, and cooking fumes from the kitchen area, making the mobile kitchen trailer safer, cleaner, and more comfortable for daily operation.
Below is a simple installation guide for connecting the rooftop fan and chimney system on a customized food trailer.
First, position the rooftop exhaust fan into the square mounting frame on the top of the food trailer. Make sure the fan fits securely inside the frame and is aligned correctly with the exhaust opening. A stable installation helps the chimney system work smoothly and reduces vibration during operation.
Next, remove the three screws from the fan cover. After the screws are removed, open the cover carefully so you can access the internal wiring and connection area. Keep the screws in a safe place because they will be needed again after the installation is complete.
After opening the cover, remove the four screws from the electrical junction box. This step allows you to access the wiring terminals inside the rooftop fan. For a food truck, food trailer, or outdoor mobile kitchen, it is important to keep the wiring area clean, dry, and properly protected.
Connect the black wire to terminal U1 and connect the brown wire to terminal V1. The gray wire is the ground wire. It should be connected together with the yellow-green ground wire from the exhaust hood to the same grounding terminal.
Correct wiring is essential for the safe operation of the exhaust fan. Before powering on the system, check that all wires are firmly connected and that the grounding wire is properly secured. For safety, electrical work should be completed or inspected by a qualified electrician according to local standards.
After the wiring is finished, apply structural sealant evenly around the connection area between the food trailer body and the rooftop fan. This helps prevent rainwater leakage, improves sealing performance, and protects the roof opening during long-term outdoor use.
For customized food trailers, concession trailers, and mobile kitchen trailers, good sealing is especially important because the vehicle may be used in different weather conditions and moved between different business locations.
Once the American-style chimney and rooftop exhaust fan are installed, check the screws, wiring, grounding, and sealant carefully. Make sure the fan runs smoothly and the exhaust system works properly before using the cooking equipment inside the trailer.
A well-installed chimney system can improve ventilation, reduce smoke buildup, and create a better working environment inside the food trailer. It is an important part of building a reliable and professional mobile food business.
