347 viewsHere the flapper is opened all of the way so all of the heated air goes into the Bus interior. This system is used by all the Types of engines (Type I/II, III, & IV).Nov 30, 2008

356 viewsFlap fully open, allowing some of the heated air to divert into the center of the Bus for the rear passengers.Nov 30, 2008

334 viewsThis is the flapper opened 1/2-way. So some heated air will enter the cabin and some will exit to the atmosphere.Nov 30, 2008

352 viewsHere is the flapper box that sits above the heat exchangers. This is the closed position so all air exits out the "bell" (right-most part of the flapper box) and into the atmosphere. Air is always flowing through the heat exchangers -- it just goes into the interior or vents to the outside.Nov 30, 2008

471 viewsLooking forward, this is the point where the main heater duct connects to the forward 'Y' where some heat can be diverted to the interior floor vent that is between the driver/passenger seats that points into the center of the Bus. Here the flap is closed so all heated air goes to the front of the Bus.Nov 30, 2008

379 viewsThe right side fully wrapped with no problem. By the way, I'd recommend disconnecting the battery when working on the Y-section and back (like this part) as the insulation can conduct electricity and there is the starter chillin' out there, with it's +12v constant supply just waiting for some action ;-)Nov 05, 2008

295 viewsLeft heat exchanger accordion duct, looking forward. For some reason, the diameter was more than 16" so the wrap didn't fully cover it.Nov 05, 2008

377 viewsI wasn't able to fully wrap this piece. It was a real pain to get the insulation on top of it. Since it is already insulated from the factory I didn't worry much about cutting up some insulation and wrapping the bottom. Maybe at a later date. Notice that I did put an 18" sheet across the top of the heat exchanger ducts that go over the torsion housing. What a pain in the neck! Trying to wrap this section wasn't worth it, with the tubes, guides, wires, and shifter parts all in the way -- very busy area!Nov 05, 2008

423 viewsLooking forward at the center section. I clipped off the stock duct zip-ties, wrapped the duct, and then zip-tied the duct back to the mounting points.Nov 05, 2008

380 viewsThis is a view -- looking to the front of the Bus -- of the dreaded "Y" section where the heat exchanger ducts merge to the center tunnel duct.Nov 05, 2008

375 viewsSame duct, just took the picture from the left side of the Bus. Wrapping this duct is likely the most difficult of all the ducts so go slow and think. I know the pictures aren't a huge help but they give an idea. I'm sure there's more than one way to insulate this loop.Nov 05, 2008

444 viewsI put a scrap piece of insulation (that I removed from the corner) under the split-loom to fully cover the duct.Nov 05, 2008

370 viewsThis picture and the next show that the corner is cut and folded onto itself. It's best to have over-lapping than a gap in the insulation.Nov 05, 2008

|
393 viewsNotice that I put a length of split-loom over the cable and wrapped the insulation over it. Again, the split-loom keep the cable from cutting into the insulation.Nov 05, 2008

399 viewsWhere it ends. Give or take several inches :-)Nov 05, 2008

405 viewsUse a split-seam wire loom around the e-brake cable to keep it from rubbing a groove into the insulation.Nov 05, 2008
