I am running an older conventional buderus wood boiler, and am having problems with the loading door gaskets. The rope gaskets only last about a week, before they stick too the boiler, probably from creosote, and start to rip off when I open the door to load the boiler. I have been cementing them in with the rutland cement, but it doesn't seem to hold them very well. Is there a silacone product that I could use to make new gaskets with , or that would adhere to the rope gaskets better?
 
There is a door gasket you can buy, I heard of it on this forum last year. It's an orange gasket with a rectangular shape that will fit perfectly into the groove, and I think you can get it in different lengths. If I remember correctly it wasn't cheap, but then neither is anything nowadays. As a matter of fact I was about to post a new thread about it myself and then saw your thread. I hope the person who knows about it will chime in.
 
I have same problem on my Royall conventional boiler. The sticking due to creosote actually will pull the braids out or pullit off the doot as you open the door I'd like to find a better gasket than the standard ones avaialble in hardware stores.
 
What about sealing the gaskets with the RTV silicone you can get at car parts stores? It's mentioned many times in other threads.
 
I was looking around online and found a few places that have some products that may work. A company called MACROSEAL INC. They have fiberglass, woven silica and ceramic cloths, tapes and ropes. I'm going to call them on Mon. Another place I found has silicon ropes is called New Horizon Corp. Also CAZtex Insulation Company Limited has some interesting concepts, such as a glass rope with a hi temp silicon sleeve. Gotta do some more research and end this smoking problem once and for all. Hope this helps. If anyone has a proven solution, please do tell.
 
Dunno if this will help, but on my EKO I spread a thin layer of high temp RTV on the gasket. I covered it with Saran wrap and closed the door. I let it set overnight, then peeled off the Saran wrap, letting it stay on the RTV where it wanted.

It's sealed PERFECTLY for two years now.

if you type ''econoburn gasket material" in this forum's search engine , you will find an excellent post with photos from NNYORKER on a high temp silicone gasket material from Mcmaster Carr. I took his advice and purchased some when i did my annual boiler cleanout this fall and replaced the red high temp silicone caulk that is called for by the factory with some of the Mcmaster Carr strips, and it worked great. When my rope gasket door seal needs replacing I will use the 1/2'' x 3/4" thick material (p/n r202104e) to replace the rope. Its expensive but it should last for years with better sealing ability.

Aren't the Eko gaskets from New Horizon basically high temp fiberglass core with a RTV outer lining? Sure looks like it to me?
