Catalytic lifespan

[ruSSrt]

Good day everyone.

I'm on my second season with Buck stove model 91. I've purchased it used and it's been going strong with no obvious issues, I had Buck 28000 before that. It is connected to 13 feet of 8" SS liner. I have Auber A100 on the flu 18" above the stove and condar probe for cat thermometer.
I have a pretty good idea about care and cleaning of the catalyst itself.
But besides it's crumbling and falling apart are there any other signs that catalytic is at the end of its life?

Reduced stove top temps and more smoke out the chimney.

And it falling out of the active range sooner (at air settings that are less low than before).

What does your care and cleaning consist of?

Care wise I make sure that I burn seasoned wood, no garbage like treated or painted. Getting it to 600 before I engage it and keep it under 1300 (with occasional 1500 quick burn).
Cleaning it with horse hair brush during burn season. And blowing it gently with compressed air before new season. Making sure I don't blow it with cold air during the season

That sounds good (gently being gently).

Yes. I dial pressure down to 50psi and keep the nozzle as far as I can from it while it's still inside the stove. After I blow the inside of the stove.

Should be a warranty in place? Sounds like you have done everything correctly. Maybe damaged pre-delivery and went unnoticed. I’d get on the phone with your dealer or mfg.

I don't have an issue. I just wanted to know what to look for.

Cats are only good for so many burning hours, I always recommend keeping a new cat on hand if you buy a used stove. Also don't forget to buy the gasket.

As per buck 91 manual:

Cleaning catalyst with plain water can reduce build-up of catalyst-retarding chemicals. Nothing but a soft brush,low pressure air or plain water should be used to clean a catalyst. The ceramic unit is fragile in comparison to restof the stove, so it should be handled with care. A soak in warm or hot (not boiling) water for 20 minutes is ideal.Then, allow unit to cool at room temperature and rinse under medium pressure under a faucet. Allow unit tothoroughly dry before reinstalling it or you will damage it. Finally, reinstall unit. A cleaning once every year is sufficient for most users. Clean it when you have your flue system cleaned.

If you take it out you will probably need a new gasket:

Obtain new catalysts #PO910115C and wrap stainless steel “can” with interam gasket and tape ends together using scotch tape or masking tape. IMPORTANT: BEFORE STARTING TO REPLACE CATALYST, contact your dealer and order INTERAM gasket and CATALYST HOUSING Gasket. Gaskets not covered under warranty. It may take your dealer several days to receive the gaskets.

I strongly recommend atleast removing one nut at a time holding the cat assembly in place then apply anti seize each season on stoves like yours. If not you may be in trouble when it comes time to replace the cat.

Thank you for the advice.
Just want to clarify. Are you talking about regular mechanic anti seize in grey bottle or is there a special high heat resistant solution?
