I really really doubt that’s the case. That’s not much use on it. Have you vacuumed it out throughly? Cleaned out debris in the back side of the cat?
Nope.
I used to remove the shield and vacuum the CAT off from the front with the ash vacuum when I shoveled out the stove.
I'm going to be totally honest here and tell you right up front that in the push of effort and curve and everything else involved with learning to live here full time, I *totally* forgot about that step both last year and this year.
(In my defense, I maintained a pellet stove in one location and a wood stove in another location simultaneously for *years.* Broke the pellet stove innards down, pulled the combustion motor and cleaned the exhaust from both ends, etc. Life got in the way in various ways right after we moved here. Details did fall off the radar- but it's all good.)
I'm full of anxiety because IT'S THE PRINCESS. AND I DON'T WANT TO UPSET THE PRINCESS.
We've never pulled the CAT out and vacuumed the back side. I'm sure that's overdue.
We were fine up until the last polar vortex. We burned hard during that last blast; it was brutal here due to our proximity to the water. Since then, we've noticed that we have to keep the t-stat turned up to keep the CAT engaged. We can get a blazing fire when the stove is not hot enough to engage the CAT. Once we engage the CAT, the fire damps down- even with the t-stat wide open. The fire doesn't go out, and the CAT will remain hot enough, but it falls to the lower half of the CAT range, closer to the threshold, unless we have the t-stat wide open.
Furthermore, when we do bend down to take a look at the CAT, either end of it will glow, but the middle is no longer glowing enough to be visible, even with the t-stat wide open.
We are reluctant to remove the CAT to vacuum the back of it without a replacement CAT and/or gasket in hand. (LOL, we had a bad experience with this once when with a pellet stove combustion motor gasket.)
What do you advise?
And thank you for your response- this is exactly the type of feedback we need!
