Maxxfan wiring

[Howard B]

Hi
Toying with the idea of replacing the rear rooflight with a Maxxfan in a 2021 Travelvan. Does anyone know if Burstner prewire adjacent to the rooflight or will it need cabling to a 12v supply in the rear lockers?

Take the current fan's interior fitting off, I did this on my Hymer to look if mine had a cable or at least a conduit... unfortunately non was evident...so I made a small hole in the insulation to route the Maxxfan cable...
Great piece of kit I must say...will get the benefits next summer...

I doubt it, often they do it in one above the kitchen but not the rear roof light.
After you have made a hole through the insulation put a length of plastic conduit in so that the PVC cable doesn't come into contact with the insulation..

Hi I have a Burstner IXEO i728G I asked Burstner the same question as I was looking at doing the same thing
Their answer was no they do not provide wiring to the front or rear roof lights
As you have a newer Travel van ask Burstner they usually reply in 5-7 days

Is air con a factory fit option? If so there will probably be a 240v cable.

My Adria Twin had that so it was just a case of finding the other end adjacent to the 240v breaker box and connecting to a 12v supply through an isolating switch.

Try removing the internal roof vent surround and you may find cabling / trunking.

Tried Burstner who couldnt/ wouldnt help, they asked me to request the info from a Burstner dealer. Given that my local dealer havent answered previous questions I asked, ill work on the assumption I dont have a 12v feed. I couldnt see anything when I removed the interier trim.
Will order a fan at the end of the month and then wait until the weather improves & I can pluck up the courage to do the work. Need to sort it before a trip to spain in a few months though. Managed to blag a length of 8mm copper pipe from my plumber to use as a conduit.

The weather is looking good this week and the Maxxfan has arrived, so I am going to have a bash at the install.
Having watched a few videos it seems pretty straightforward. I think the hardest part will be getting the old rooflight out and trying to feed a cable route through the polystyrene roof insulation to somewhere above the rear lockers . I plan to start it off with an 8mm x 300 drill bit and then try a length of 8mm copper tube for the final 200mm.
I guess if its straight & i measure correctly I should be able to drill through the top of the locker to pick up the copper tube in the roof insulation. .
Need to make sure I dont drill throgh the out skin of the roof as well.

Thanks, will try & push though by hand rather than using a drill, though there is timber around the skylight opening which will need drilling.

If the insulation is polystyrene either put a length of plastic conduit through the roof or even leave the copper pipe in there so the cable doesn't contact the insulation.

I was going use the copper pipe as conduit.

Mine went through the insulation quite easily by hand.... wouldn't want to trust myself with a drill, far too risky...Maxxfan great bit of kit, had ours on this afternoon...
van was a tad warm...

Was that with a drill bit or copper pipe?

I would use a drill bit, but twist it by hand.

Pipe...couldn't risk a drill...one mistake and I'm repairing a roof...

 

[Howard B]

I started the job this morning hoping i would be able to finish today. Old roof light off and area cleaned up and new insert installed within a few hours.
I am having issues getting through the roof sandwich to the rear lockers. I am able to get from the roof light arae to the lockers which is @ 550mm. However I need to be at @ 580mm to be inside the locker ara.
Directly above the lockers there must be an aluminium or steel plate which I am unable to penetrate at the moment. I have tried two routes and have the same result each time.

Options now seem to be:
Try & buy a drill that will cut through metal. Not sure if something like this is worth a try. https://ffx.co.uk/product/Get/Bosch...VYsfuj0aT4okFRJqHXKgxIi6TlduEDyRoC5FQQAvD_BwE
Surface mount the cables

Any thoughts?

You twist the drill by hand, silly boy.

That looks like the back of the van so could be a bracing strut where the rear end joins maybe better going via a side locker.

Some drills go through anything.

https://www.motorhomefun.co.uk/forum/threads/where-to-put-the-maxxair-fan.242753/

Joking aside can you get a long HSS bit? It will go through wood or aluminium then, though I would be wary of the drill wandering through the roof which would be disastrous.

Personally as long as I could it inside the locker, I would then be happy to surface mount it neatly.

I would be tempted to go through a side locker too.

Distance may be a problem then. I can give it a go, but my augers wont be long enough. Ill see if the Aluminium tube will push through, may be difficult trying to locate the end if i go off at an angle.

 

[Howard B]

Just tried a route to a side locker, same issue.

 

[Reallyretired]

I have some wiring in the way so surface mounted it with a small decorative half round conduit. Not as neat but no risk of drilling through something important.

 

[Landy Andy]

All depends on how brave you feel. I’d cautiously drill it, but it’s the sort of stuff I do for work.

Think I may have to look at surface mounting, not many places seem to stock 8mmx 600mm HSS bits.

But the Drill Bits I have are marked up as High Speed....I would have had problems twisting them that fast with my arthritis...The pipe method worked very well for me..was like taking a core out of an apple.....There is always a different, but not always the right way...Maxxfans are Brilliant...

Pipe method was working fine for me until the last 50mm.

I was going use the copper pipe as conduit.

Watch out the inside edge of the copper has not got a sharp edge as in time it will cut through the cables insulation. As said before plastic is better it will condensate with water as its a cold metal surface also
