Hello everyone,


Has any one tried using '' Ceramic Exhaust Wrap '' used to wrap engine manifolds and exhaust straight pipes to make your own secondary burn gasket to seal the top of the secondary air supply tube and the bottom of the stove baffle instead of using the factory ones for the Super 27, Spectrum's and Summit stoves.


This stuff is good to 2000°F and could be a solution for making gaskets instead of purchasing and replacing a OEM gaskets every time you remove the baffle to clean and inspect the stove. It normally is 2 inch wide and can be purchased in various lengths. Just not sure how well it would work inside a firebox and resist flames.


What are your thoughts on this ?

It should resist flames just fine but who knows if it will seal properly or if it is the right thickness and density ect.

It is 2mm thick or 1/8'' for the ones how do not know the metric system, which is why I am inquiring.

Not really sure and the stove is blazing presently, but it was not all that thick, it seems to me perhaps a bit thicker than a quarter, my memory could be wrong however.
 
Might work, the temp rating is good. The gasket surrounds the rectangular secondary tube. Thickness is not the issue, it's more how are you going to make a continuous gasket with it. 3/8" rope gasket works well because you can make an oval with it that will conform to a rectangular shape when placed around the tube. In order to use flat gasket material like shown it would have to be the tube's narrow dimension plus say 1/4 to 3/8" on each side or roughly about 1.5" or 1.75" wide. So the concern is whether the weave would stay together with those narrow sides or not. Worth a try if the stuff is cheap and you can get a short length.
 
I might check that out. I used a ceramic blanket matting I found on Ebay last time around. Got a second year out of it, but doesn't look like it will go another year. The new gaskets are full length of the back rail, with the hole cut out for the secondary channel.

Did you get any pricing on it?

2mm = .079"
3mm = .118"
 
What's the purpose of the gasket? Right now my PE Summit is running without one.
 
Keep the channel air going into the baffle.

No not yet but I know a new roll is not expensive, I was thinking that this might be an excellent material to make these gaskets with. Probably worth hitting performance engine or motorcycle chopper shops to purchase cut-offs of this material to make a few prototypes.

I need to first order a new replacement gasket from a dealer to use as a template or manufacture a template from the OEM part.

To ensure your stove is operating at peak efficiency as designed and ensures your air is controlled correctly.

The gasket stops air leakage at the connection of the baffle to the secondary air supply tube. Without the gasket there will be some minor leakage there. You may see this with flames dancing at the top back center during the secondary burn phase.

As a matter of fact I do, that explains that, I'll replace it in the spring.

I haven't seen one yet that runs the full length of the back rail? Do your know how long that change has been around. I carry spare gaskets with me for sweeping and my supplier never mentioned any newer type of full length gasket?
 
This is on the Summit B and C models. It's number 26 on the parts diagram. The feed tube hole in the diagram appears to be similar but the gasket looks to be full width of the baffle.

As I have advised in the past, you're going to see secondaries in the back in any case. There are secondary port holes in the baffle at rear between the lower wrapped edge. It is made to burn this way.

As far as I know, only the A series bodies have the smaller, rectangular gasket. The B series, has a full length gasket, I can only assume the C also does. I have owned an A series and B series, so that is all I can attest to.

I have a pc of welding cloth another member sent me, that may work also.
 
Parts diagram posted if from the C model. Does this match your "B"?

A,B, & C series?
Refer to sizes ? Manufacture date? Body style change?

T series all take the rectangular gasket according to my manual.

Edit: doesn't make sense T4=series "C", T5=series "D", T6=series "A" according to the Labels.
They all use the small rectangular gasket according to my 2007 manual.

Interesting my summit is a 2015 b series and I thought my gasket was the smaller rectangle one that just fit over the secondary feed air tube. I felt certain it was atleast and that's what I replaced it with when I cleaned it at the end of It's first season, and when I pulled the baffle off I messed up the old one. But now I'll have to look closer this year and see if I can find any evidence of it? And replace it with the proper one I suppose too? I'll compare it to my older super too. I wonder what the difference is? Helps to support the baffle equally all the way across the back ensuring it sits more square on the secondary feed tube possibly?

Thanks a lot. I'll be keeping an eye on this a little closer now for my customers thanks to this info.

Iterations of the Summit line. A, B, & currently C. The latest Alderlea T6 has the old style gasket still, though it is now the series "B"
