Firebrick on floor of 1979 Resolute

[snydley]

I have an older Resolute stove, given to me a few years ago. I decided to cut some firebricks and place them on the inside floor of the stove instead of having a bed of ashes in there. Although I've been running it like this for 5 years now, is it ok to run it like this? Will it burn properly with the damper closed? The firebrick does not cover the air holes in the back of the inside of the stove at all.
I may have already asked this before, sorry if I did.

Interesting. I just keep ashes in the bottom of my Resolute. It seems to protect it just fine,

Mind you, I am only burning Envi logs. They keep the stove at 650-700 degrees, and I only clean the ashes out once a month.

I ended up putting firebricks in the bottom to try to keep some of the heat off the hearth and to make it easier to clean. Then I got wondering if that would somehow restrict the secondary airflow.

I have a resolute 2, and have thought about installing firebricks between those fins on the bottom to increase thermal mass as well. However, the air holes are very close to the bottom that I'd think the ashes would pile up and into them a lot easier. The fins on the bottom are to seat the ashes.
What's your average running temperature, and what's your peak?
