Make your own Combustion Blower Hi Temp Lytherm Gasket from Sheet

[imacman]

I actually bought some VersaChem (made by permatex) Mega Copper high temp gasket maker, part #88839 good to 700 degrees. used it for a week now, works great!! Tube will probably last up to who knows how many gaskets. When you redo the gaskets can just scrape off the old with a razor blade. used it on manifolds before, those actually get hotter than a pellet stove. No stove shut downs since, E1 codes gone. When I removed the old gasket from englander stove (fall apart gaskets) it was in 5 pieces when I took off the exhaust blower motor! That may explain the vacuum leaks before I took it apart! Bought the new gasket maker tube at O'reilly auto parts, $5.95 a tube. It actually has copper powder in the silicone. Good luck.

The typical gasket used by almost every stove manufacturer will "fall apart" like yours when you remove the blower.....nothing unusual there. Unless your PDV was a used stove, and the previous owner didn't do a good job replacing the blower gasket, I doubt there were vacuum leaks there.

Hello

Lytherm gasket material is good to 1,000 Deg or so. That is why Wood Pellet Stove makers use Lytherm. However you do not have to pay $20 to $30 for one gasket when you can make your own gaskets much cheaper.
Example: You can get 4 -- 5-3/4 inch gaskets on one sheet!
That is $1.75 per gasket! YEA ! !
You can get the Lytherm gasket Material sheets from Brunner's Bits and Pieces or E-Bay or Wood Heat and Solar for approx. $7.00

Wow $7.00 per sheet here from Brunner's Bits and Pieces!

Wood Heat and Solar $18.00 per sheet

Here is how I did.
I made a Template. You can use paper or cardboard, or posterboard. I used cardboard here.

1. Measure the outside diameter of the Combustion Blower and divide by 2 for the compass setting.
Example: 5-3/4 inches so half is 2-7/8 inches
2. Set the compass to 2-7/8" and draw a circle on the template.
3. Cut out the circle.
4. Reduce the compass setting by 1/2" and draw the inside circle.
5. Cut out the inside circle
6. Put on the blower, check for fit (Trim if needed) and mark bolt holes with felt tip maker, pen or pencil.
7. Use a paper punch to punch out holes in template for bolt holes.
8. Trace template on to one corner of Lytherm Sheet
9. Cut out template
10. Punch holes

Easy Peasy and $ave some money!
Do not worry if it does not come out 100% perfect, it does the job!

See pics below!

I did this right from the onset. Just remember to save your outline for the next time. Why pay more for the precut!

Good work!

I did this from the onset also. What I did though was outline the exhaust blower when it was out and while I was pressing to the lytherm it left enough of an imprint to see where it needed to be cut on the inside.

I noticed Brunner's bits and pieces there is 1/4" and 1/8" is the 1/8 sufficient??

The stuff I used wasn't 1/4 th in. thick. The stuff I took off that was the original wasn't that thick either. What I put on has worked out just fine. My replacement is stronger and I think holds up better than the one that came with the stove.

This is what i used recently......$7.99 i believe......1200 degrees F.

Thanks for all the info.

Don't they make a "re-usable" material??

200th post Woo-hoo! Where's my prize?

Would this stuff work to make the flue adaptor gasket? The red diamond shape gasket under ammo can.

when Im out of the stock gasket I use 1/4" window/flat tape gasket with the adhesive on it. works great. and dont fall apart the next time you pull the blower off.

How did this work out for you? Thinking of using the same since it is very easy to get near the house.

This worked well for me. It was part of a reconditioning on a 1991 (Travis industries) Avalon pellet stove I bought recently. The gasket would have cost 20 dollars easy from the pellet stove dealer nearby. I used these sheets and have enough for a leftover repair in the future. Good luck on your plan.

Thanks Z. Bought a sheet for 8.99.
