So, let’s get down to the juicy part!

Installing Your Maxxair Fan

Step 1: (Con)Template and Measure – The fan requires a roof opening of 14”x14.” (Confirm the measurements with your specific fan and the manual that it comes with). You’ll want to cut out a 14”x14” cardboard template, mark the center and drill a hole right through it. From the inside of your van measure, measure, measure, and again, measure! Measure and mark the center or the van/vehicle or if you don’t want it center that is also an option. Measure it exactly where you want it. Then, make sure your cardboard template lines up and mark your square all the way around. 

Step 2: Using your drill – At each corner use an x/x drill bit to make a large enough hole for your jig saw to fit through. Be careful, do not drill too close to the corner so you don’t cut the hole outside of the lines.

Step 3: Tape it off – Now you’re ready to place the template on your roof. Use the holes as guidelines and tape off a 14”x 14” square. It can also be helpful to tape from the inside of the square to help with vibration when you go to cut. 

Step 4: Bag it (Optional) – On the inside of the van, tape a bag around the square to catch the metal shavings that will fall while you’re cutting. It’s very important that you clean the van very well after as those shaving will rust. 

Step 5: The Scary Part – Using your jigsaw, grinder, or any other machine of your choosing, cut the hole!

Step 6: Sand, Clean, and Rust-Proof – Sand down the edges with the metal file. Apply Acetone or alcohol to clean the metal edges and about 2” around where the fan will sit to ensure a clean seal. Then use the rust-proof primer and rust-proof it. You can spray it directly or spray onto cardboard and brush it on for a cleaner application. 

Step 7: Frame it – From inside the van create a wood frame around the 14”x 14” cut out. Use Powergrab or any other construction adhesive to initially secure the frame to the van/vehicle. You can use clamps and cargo bars from below to apply pressure. 

Step 8: To Butyl or to Not – If you have a flat surface adding Butyl Tape may be unnecessary. For those that do not use the butyl tape around the edge of the 14”x 14” hole to level out the surface.

Step 9: In Goes, the Flange – Apply two parallel tracks of sealant around the flange and insert them into the 14”x14” hole. Ensure that the metal clips are facing the long side of your van (not towards the driver or the backdoors).

Step 10: All the Pilots – Drill pilot holes all around and secure with screws provided. Start with corners and create even tension between screws that way they don’t start to misalign if only screwing from one side.

Step 11: Seal it Again – Apply more sealant all around the flange and on top of the screws. If you didn’t create a wood frame for the interior, you can apply extra sealant on the interior of the screws for extra measure. 

Step 12: We’re done? – You’re almost there! Fully open and insert the Maxairfan into the receiving flange. Ensure that the wires are falling out of the fan and are accessible. Then, secure the max air into metal clips with screws. Note: you may need to raise the metal clips to screw it in. 

Step 13: You’re DONE! – The last step is the garnish ring. After you have installed your finished ceiling measure and cut the garnish ring. Measure each cornerp there may be a slant. Then, fasten into place with flat head screws.
