We've had some "warm to us " weather, around & above 30°f for about a week.
I decided to burn some spruce to see how well it burned.
I started on high, got the stove pretty hot but the cat never went much over mid-range or just over.
(no temp markings on the cat probe,)
Well it finally got back to close to normal & in the single digits last night so I did the basics to get a hot fire burning.
The spruce lights off quick, the stove & flue get hot but the cat doesn't.
When I closed the bypass, the fire would go out, I tried several times, but fire kept going out.
I notice the cat not glowing like normal. Decided to put in some small pieces of birch to see if I could get
it hotter & glow red like it should. It took several tries but it finally lit off but took a while to
glow evenly across the whole cat.
What I learned: burning spruce on medium for a week had slowly clogged the catalytic honeycomb & when I closed
the bypass, I was not getting enough draft to burn. I don't know if the wood was too wet, maybe the pitch in the
wood, (combination of both) but it did not like to burn well except on higher settings
I notice after after a few days it kept getting worse until not enough opening on the cat to burn.
I do notice some creo on the chimney cap but the flu itself looks ok.
Burning the birch hot, got it hot enough to clean it out & is burning fine now.
I know Beetle-kill had similar issues, just trying to identify the problem so I can fix it.
I though my wood (spruce) was pretty dry, it burn with a vigorous flame, lights fast but slowly clogged the cat.
Any ideas?
I said to myself "It's the wood , stupid", but not sure why??
