What adhesive?

What type of adhesive do they use to secure the rope type gasket material to the doors and ash access doors for these things? The seal on my Keystoker came loose in a spot I wanna button up...

good question. i don't know. i need replace some glass and was wondering the same. just put the glass in with nothing or some type of adhesive?

You can buy an adhesive from the stove retail stores that is made to hold the gasket material in place.. Personally I don't like it, it is thin and watery. I use high temp Silicone RTV gasket sealer. I prefer the Permatex 'Ultra Black' sealant. It handles the heat well, and if applied to CLEAN surfaces sticks well.

The thin, watery stuff is probably "Water glass", available at Sid Harvey. At efm, we spray regular contact cement onto the iron or steel surface. Give it several passes, a heavy coat, wait one minute and apply the gasket.

what about glass to the window door ??

The gasket on a window is a very thin, flat ribbon gasket. The gasket that Leisure Line ships with their door glass has a self adhesive on one side. You pull the paper tape off the adhesive and stick the thin gasket over the edge of the glass wrapping it over the edge onto the sides of the glass. This makes a perfect 'U' shaped gasket around the perimeter of the glass.

Remember, don't try to clamp the glass solidly to the door, the glass will break. The door and the glass expand different amounts and need to have some 'give' between them. That is why the screws that hold the glass in place have soft flexible 'washers' under them that actually apply the slight pressure on the glass.

The thin watery stuff is sodium silicate. It is kind of a pain to work with. I've always used it but I think next time, I'm going to try Gregs suggestion.

3M spray adhesive.

Well I opened up the ash door last night to empty the ash pan and the door gasket fell off. I took Greg's advice and got the permatex RTV ultra black and it worked great. Didn't even have to shut the boiler down. Thanks Greg.

I carry a product in my store by Rutland fire clay co. item #77 HI-Temp stove and gasket cement. It comes in a tube and is good to 2000 deg F. Silicon works good but does have some heat limitations. Rutland #77 should be available at any hardware/stove shop

I've used the Rutland #77 on gaskets for several years - it's worked well for me.

Good to know. The permatex ultra black is good to 500* so it worked fine for the ash door. If I need to replace the combustion chamber door, I'll get the Rutland.

At least a few years ago there was an RTV Red that was good to 650 degrees - I used some in my boiler with no problems.
