Eberspacher exhaust question

[KenMcCulloch]

Our Eberspacher lives in a cockpit locker. When taking it out for service this winter it emerged that the exhaust needs renewing, basically it was a crumbling tube of rust held together by lagging. As installed, the insulation of the exhaust left about 3-4 inches of the exhaust elbow exposed. We learned early on to keep warps and other meltable things away from that. It's the type of elbow with a coiled copper condensate trap fitted. I have the materials (flexible exhaust pipe, lagging and an outer protective duct, clamps etc.) for renewal of the exhaust system

My question is this: is there any reason why the protective lagging on the new exhaust should not cover all of the previously exposed elbow? It would seem to be a lot safer to extend the lagging to cover as much as possible, but I wonder if it was done the way it was for some good reason.

Our exhaust fitting sounds a lot simpler than yours - no condensate trap and no elbow as such - but all the internal parts are lagged (some kind of foam inside a lightweight metallic trunking).

Yes, lag as much as possible, there is absolutely no reason why it should not have been done that way initially, be sure to use exhaust assembly paste on all joints. If you can find some stainless tie wraps they are great for securing lagging tape but I rarely use tape any more, I normally use this stuff now. http://www.mikuniheating.com/Details.cfm?ProdID=518 available in three size tube and also flat sheet.

That lagging looks perfect
