How to Install the MaxxFan Deluxe Roof Vent on a 2018 Nissan NV 2500


Shane: Hi, I'm Shane with etrailer.com. Today you're going to be taking a look at, I'm going to walk you through the installation on the Maxxair Fan deluxe roof vent on our 2018 Nissan NV 2500. This going to be designed to help circulate air inside of the enclosed area. For instance, a lot of people are taking these vans and they're either converting them into their own campers because they can design them the way they want or they're making a mobile business out of them. This is going to lie you to ventilate that inside air to make it more comfortable, whether you're sleeping or running your business.Our cover is going to be a smoke cover, so it's going to reduce the amount of sunlight that's going to get in. Not only that, but you can notice it's really streamlined design, so it sits pretty close to the roof of the vehicle.

We're not sticking up real high like some of the other styles out there. It's going to be a really, really durable plastic, so it's going to hold up in all weather conditions. The cover is also going to be a rain cover, so it's not going to allow any water inside the vehicle when it's raining, whether it's open or closed, it's going to have a full screen to keep any bugs from gaining access into the vehicle when in use. Also, on the bottom right down in here, we're going to have a rubber seal that runs all the way around this inside housing or where this housing comes down on top of this base to keep any water from getting inside down there. So it's really sealed really well.This is what our roof going to look like inside of our vehicle.

Let's go over some of the features. Well, to start with this is going to be a manual open and close, so we just turn this knob to open and close it. Now again, this fan can be used whether that vent is closed or open it has a full screen on it, so it's not going to allow any bugs or any water inside. Then our lid is also going to have a push to lock feature, so when we we're traveling down the highway, we had it closed, we can push it and it'll keep that lid from coming open.Now, if we come right down here to this back corner, this is going to be our function pad. We have our on and off.

We have our input, which will change the direction of our fan 'cause we can either use it as a ceiling fan or we can vent air out or pull hot air out. We have temperature settings so we can set a temperature and it will automatically turn it off and on by itself to circulate air, get to that temperature. This is going to be our speed control. We're going to have 10 different speeds to you get our fan of the full speed when we need it or really down low.Now, one thing I want to mention, this fan is very quiet so whatever you may be using your van for, whether it's a camper, it's not going to disturb you even at full speed. So let's go ahead and turn it on and see where it sounds like.

Keep in mind, I do have a microphone on so it may sound a little bit louder, but it was not loud at all. Go ahead and turn it up. We're at full speed. Now, what we'll do is I'm going to hit the in and out and you'll watch the fan stop and it's going to switch directions. Now, assume it's pulling air out. We can use this as a ceiling fan option where we can have our lid closed and still run our fan.Spot right here, this is going to be our temperature gauge or a thermostat for the inside. One thing I do want to mention: with this fan you have the auto setting for the temperature, it's only going to be able to be set at 78 degrees. It doesn't allow you any adjustability. But that being said, when you turn that on auto the fan's going to turn on and off by itself to adjust that air to get it to 78 degrees.As far as her screen goes, unlike some of the others, this one is very easy to take off. To remove it, you simply turn these tabs to the side, and it slides right off. It allows you to maybe clean off your blades on your fan, clean off your screen a little bit, and you can put it right back in place. Really easy to access for any maintenance that you will need to do. Now, if you're looking for a type of fan that may have more adjustability for air temperature or maybe he has a remote control, we do have those here at etrailer.com. There are other types of fans available. Again, this one has a rain guard on it, but there are other types that don't have the rain guard, but they have a rain sensor. So if it detects any moisture that vent is automatically and close by itself. You don't have to mess with it.Now, as far as the installation goes on this, it's really not difficult installation. It's pretty simple and straightforward. It is going to require a 14 x 14. We will be cutting the roof. Also, is going to require roofing insulation kit. That's going to come with butyl tape, it's going to come up with your screws, and it's also going to come with some self loving seal or for the top so it doesn't allow water to get inside the vehicle.Now that we've gone over some of the features, let's show you how to get it installed. We're going to start by coming inside the van and we need to measure between our ribs and make sure we have at least 14 inches in between them, because what we don't want to do is we don't want to actually cut into the rib, 'cause that's our roof support. So you can see here this rib's a little bit short. This is originally where our customer wanted it, but we're actually only at 13 and 3/4. So in order to get that 14 x 14 we had to cut in here, so what we're going to do is we're going to move it back one and measure here. Right here we're at 14 and 3/4, so that's going to give us enough room. We won't have to cut into either one of the ribs and we'll have just enough space inside here that the ribs will support it.I did have to move this light. This light was actually flipped over here. I just flipped it around. Our customer actually had it covered, so I don't think there's going to be using it, but I don't want to just hanging so just make sure wherever you're putting it, you get any items like that out of your way.Once you determine where you're going to put your event, there's a couple things you're going to need. We need some luan board and it'll look like this, very thin for a template. You're in need 1/2 inch or 3/4 inch piece of plywood about this size. I'm going to use 3/4 inch because where our ribs are, normally we would do an 18 x 18 square and have that frame come all the way out around the 14 x 14 square, except between the two ribs we're only going to be able to come out a 1/4 inch. So, when I bolt down from the top, I don't want to come all the way down through my vent shroud on the bottom, so I'm going to do three 1/4 inch. That'll give my screws plenty of width to bite into. A level. You don't necessarily need the level, but at least the straight line. Speed square, it'll work good. Get a couple of bolts, small ones, nut and bolt, and two flat washers, painter's tape, and some wood glue.Our first step is to make the template, and that's out of the luan board. So what you're going to do, and I've already got one made here, but you're going to take your luan board and you can go from an edge. You're going to do a 14 x 14 square. Make sure that your board is square, measure across and then measure corner to corner just to make sure you get the same measurement.Once you do your 14 x 14 square you're going to put a mark in each corner that is 7/16ths in from each line and you're going to do four of those, and you're going to find the center. You're going to drill a hole in the center. You want to make sure that your bolt is going to fit through there. What we're going to do is this is going to be our template for the inside to make sure that our fan is centered or is going to be center between our ribs. This bolt's going to go through like this, we're going to actually, it's going to be bolted to the roof pretty much. Now, we'll move to the next one. We'll actually put one on here and then we'll drill out those four holes. That's going to give us our four corners to cut out this square on a roof.So now what we'll do is we'll take this, we're going to set it in between her ribs. We're going to drill a center hole all the way up through the roof. We're going to hold it up on the inside. We're going to make sure we're even between our ribs and centered where we're wanting it. I'm going to take a 9/32nds drill bit, make a mark right here. Now, take your bolt with your washer dropping down through the roof, put on our next washer and our nut.Little tip: Now, if your board seems to move one way or the other, if you make this whole just a little bit bigger, because this whole square is going to end up getting cut out, nick the board hole a little bit bigger. You'll be able to shift it back and forth one way or the other to get you even. So now what I'm going to do is from here I'm actually going to take a smaller drill bit. I'm going to drill a pilot hole right in the center and then I'll open that up and then I'm going to drop one more bolt down through one of the corners to drill out the rest of them. That'll keep my board from moving, and I'll drop another bolt with my washers down through that one. Once we get our four holes drilled, we're going to take our template down and we're going to move it up to the roof.We're going to put our bolts back in place, go ahead and tighten it down, and you'll move to the next set of taping it off. So we get our 14 x 14 square.We're going to tape it right along her edges. Right on the next board. You got to make sure you don't stand on your roof, 'cause this, the metal is pretty thin. You don't want to bend it or fall through it. Once you get your tape on you can remove your template. Now what am I do is I'm going to open these holes up to where they're just touching my tape in each corner and that's going to be my 14 x 14 square. I'm going to use a step bit. You can use a bigger drill bit if you want. It's already there.I'm going to take a jigsaw metal cutting blade. I'm going to cut around on the inside of my tape. So now I'm going to do, every time I cut a line I'm going to take this tape and I'm going to go from the panel over to the side. That way when I get to the last one this doesn't just fall down inside. Then we're just going to work our way around til we get our square cut out. Then we can take our piece that we cut off and pull it out. There's our hole for our vent.Now I'm going to take a small file. I'm just going to go around this edge and knock off some of the burrs, if there are any. Now I'm going to take some clear coat. I'm going to cover up this bare metal here. Next we need to make some shins so that when we screw our top down at screwing into something. This is going to be our top piece that we're actually going to be screwing down to our roof, and our holes, you can see they kind of come out inside these ribs. So what we're going to do, I'm going to take the inside piece--it'll look like this--and rather than cut it to fit up inside of there I'm going to make shins for that. That way my top piece has something that screw into, not just the sheet metal.So because that gap's so big, 3/4 inch plywood, we're going to cut two pieces for each side here that are 14.5 inches x 1 3/8ths inches. Then you're luan board, you're going to cut. It's going to be 13 x 1 inches and what the luan board is going to do--I'll give you an example here--is actually going to fit in this gap to make this flat, so what we're doing is we're going to glue our pieces together and it's going to sit just like this, and I haven't cut this luan yet, but you can see what I'm trying to do here and we'll have that on both sides.When you get your luan cut, test fit, make sure it's going to fit in there. We're actually going to be gluing all of our pieces together before we stick them up here. If you glue it together without measuring or testing it out, what might happen is your luan board might be over and it may not seal against there. So what I suggest is taking one of these, you're going to throw it up like this, and you're going to mark right at that inside edge, pull it down, you know you have to glue this in between those two lines, and we'll glue our other two pieces together, put a clamp on them, hold them together, let them dry for a couple of minutes before we install it.Now you want to take your base. This is a base to your fan. It's going to go on the outside. It's going to go just like this. We're going to clamp it to the roof. You want to make sure you don't clamp it real hard. We just want it so it's not going to move, 'cause we're going to be drilling the holes for our bolts. Now, there's a couple of steps here. From the inside you can either use your framing that you made or just use a piece of wood and put it in there to hold it in place.Now we have corrugation that we need to fill on the outside, so our luan board that we have, we're to use it to fill this gap. So what I did is I cut a piece 5.25 and I slid it in like this, then mark it. Now, I'm going to cut this edge off so that's even with that, and I made four of those. So we'll go ahead and cut these off, get our shims ready, then we can start drilling our holes in our roof. Now with our shims cut our base is in place. We're going to take a 13/64ths drill bit and we're going to drill our holes around the outside. We want to make sure that this is not going to move. We just want to go through the metal so if you have your frame in there make sure you're not going all the way through the frame.This edge right here we don't have a wood base that's going to be under it. It's going to go right into the beam for the roof report. So, I'm actually not going to drill that hole. I'm going to use self tapping screws in here, on here and here. So all I'm going to be doing is drilling these two sides right here that are going down into my wood.Now we turn to our clamps. I'll go ahead and remove the base here like that. Pull up our tape. You can see what I'm doing now. You're going to need 2, 3 foot x 1/2 inch aluminum strips like this. If you can find them in 3/4 inch wide, I would say they'll probably be better. It's going to give you a little bit more room for your holes. The reason you need this is when you screwed down this to our roof, this plastic frame, we don't want it to crack and it could potentially crack over time because of where it is. So the strips, what they're going to do is they're going to kind of disperse the downward pressure of each screw head. So all we're doing is we're matching them up with the holes. You can use tin snips. It's real easy to cut. Let's take a pen and slide it in like this.Take a piece of wood, same drill that you used on the roof for year three holes on each side, and you're going to drill holes through the aluminum strips just like that, and there's your metal frame. It doesn't matter what it really looks like. It's all going to be covered up with a self leveling sealer. We just want this so we don't crack this base when we screw it down. That's where we're going to take our butyl tape. Typically, what we would do is we are going to take this plan here or this a base and we'd stick it on this edge. However, we have shims that are going in here. So our butyl tape is going to have to go on the bottom of the shims and we're going to get butyl tape on top of this top edge here. So, instead of putting it on here first, what I'm going to do is I'm going to put it on here and put my shims on the top, put this on top, and I'll have the butyl tape in every place other than the top of my shims.Set this to get an idea to make sure my tapes in the right place. What I'm looking for is to make sure that the butyl tape is covering my holes. Nice girls. Now, I can take my shims and set them place. I'm going to take an extra piece of butyl tape and I'm going to stick it right here in the center, even though when I screw down, it's going to smash this, this I'm afraid is not going to be close enough. I just want to make sure I'm not going to get any leaks. Just precautionary. I'm going to go ahead and put an extra piece in here.Now what I'm going to do, because my center is just a little bit higher, I'm going to go ahead and put another piece here. Instead of putting on top of this, I'm going to actually put it on this edge. So if I didn't mention it before, you want to make sure that these tabs are going to the outside, not front or back, 'cause when you put your event on top, it actually screws into the sides of it so just make sure when you're doing that you put it in like this and not like this.Now what I'm going to do is this edge and this edge is just going into metal, I'm going to go ahead and put these in to hold my tap in place before I put my wood bracing on these sides. Take some self tapping screws. Going to make sure that you put your metal strip in there. I'm going to do the same thing on this side. We'll clamp our frame up here. We don't want it so tight that we crack that plan, but want this to hold in place. We'll put one on each side.Clamps off. Then we can cut our excess butyl tape off. You don't actually have to touch the roof with the knife. All you got to do is score this stuff and it will pretty much tear off. Now we're going to set our vent in place. You're going to make sure that the outside flange goes over top of that bottom ring, and we're going to line up the two holes on each side with the two holes in the bottom. You're going to make sure that your hinge, or you can see how it's leaning up cause it opens this way, make sure the hinge side is going towards the front. Side that opens is going to the back. You don't want that site to the front because you don't want wind to catch it.You're going to get some shorter. Phillips head screws are going to be a little bit fatter than the other ones. There's only going to be four of them. Those are the four that go inside the edges here. Now, from inside I'm going to take our trow, we're going to have to cut this piece to fit because it's not a normal install. So what we need to do is figure out the distance between here and this edge. I'm going to get myself a little extra space, so I'm going to cut it at two and three quarters. Now we have got plenty of room that this will meet here.You want to measure 2 3/4, so a couple of marks like that. We're going to do that all the way around. You want to take a Dremel tool, a plastic cutting blade, and cut that out. If you don't have a Dremel tool you can use a utility knife. It'll work just as well. Now I'll go back, clean this up. If some of it won't come off just take a knife and run it like this right on the edge.I'm going to take my wiring because we need to hook up to a 12 volt circuit. Probably going to run to the front of the vehicle, so I need to make sure that this is running whichever direction I'm going to go. Now, like this inaudible 00:23:14 make sure it's fit in there, that my water's coming out right there like that. I can run a screw here, screw on this side. That'll hold that in place. We've got to run power to it and put ourself while we're on the topI'm going to go ahead and install my ground wire. I'm just going to take a self tapper and put it right here. As long as we're on metal we'll be all right. Take a knife, strip it, add on our ring terminal. Take a self tapping screw, just like that. Now, for my power wire. There's different ways to do this. What you want to do is run it through a positive power source. You can extend it, run it straight through your battery. You can run through like a light like this. Keep in mind, some of these lights are timed so they're going to shut off. You may have to have your key in the on position if you're wanting to use the fan.this customer is actually going to have a mobile grooming company for animals, so they have a converter in the back that's going to power the pumps and everything for the vacuums and the draining of water and everything. So what I'm going to do is I'm going to run this wire back to that so that whenever she is parked somewhere she can use that converter to power everything.We're going to test out our fan, make sure it's working. Once we know it's working, we can start putting our installation back on. We can put our self leveling seal on the top. We got power. Okay. Now we know it's working. We're going to finish up our install. Now what we're going to do is we're going to take some extreme self leveling sealant, white, and what we're going to do that we're going to go all the way up against the edge. We're going to cover all of this. We want it to come down over the top. We're going to do this all the way around the edges. We want to make sure we have good coverage. You're going to make sure you let that self leveler sit for at least 24 to 48 hours. You want to make sure you got a good hold on the roof of the vehicle. You don't want any water to get inside.Again, I'm Shane with etrailer.com. I hope this video has helped you whether you're still deciding or installing the next air fan deluxe roof vent on your 2018 Nissan NV 2500.

What is the thickness of the luan board for the Maxx fan install please?

Etrailer Expert
Reply from Jon G.

I would guess that it was somewhere around the 1/8" - 1/4" thickness when compared to that 3/4" board that Shane holds up. The thickness on that luan board doesn't really matter as much since it's only purpose is to be used as a template.
