Door gasket shot already?

I bought a Cozy Heat 231 ZC about a year and have enjoyed it. My problem is the door gasket is completely shot after about 40 uses. Am I doing something wrong? Is there a better aftermarket option?

Thanks,

Take some hi temp. silicone put a good amount all around the door where the door meets the boiler,then put a
thin strip of waxed paper on the goo and close door for several hours or until the goo dries. This will make a nice seal and excess paper can be removed repeat as required.

Good idea, thanks! I will keep this one in mind for the future.

The gasket on my parents Lopi went bad the first winter they had it (one corner was stretched too much on install, and left a 1/8"x3-4" gap).

Only took 2 or 3 years of me mentioning it, and them complaining about how poorly it ran, for my dad to finally replace it. "wow, it burns so much better now..."

Anyways, sometimes they're bad right out the gate.

Also the standard white gaskets can stick and mess up easily. That us why I prefer the high quality Graphite
Impregnated gasket!

I had in mind to use this technique to give a better seal with my pellet smokers. The question I have is if the time comes that I want to redo this, will it be easy enough to remove the old silicone from the metal it adheres to?

Yep,just pull it off it will come off much like removing a gasket and you can take a wire brush to get any small stubbing pieces and clean things up. I have the same gasket for four years now just
reapply the goo sometimes you done get much time sometime a season like the one on there now.
guess it matters just how much and how thick you put the goo but sure beats buying new gaskets.

silicone has its merits, but can be very hard to remove in the future, and can turn to powder if it gets too hot

I had blue Permatex RTV turn to a rock hard cement in the gasket channel and will never use it again for a gasket. Now I use Meeco's without issue.

The stuff I used was from Home Depot the Hi temp red in color never had any issues with it stayed soft
and easy to remove.
