Cracked Fire Brick

Cracked Fire Brick

PostBy: Swamper On: Thu Dec 11, 2008 12:49 pm

We're now well into the heating season and I'm enjoying my TLC-2000. (My oil guy doesn't). Got a warm day and decided to let the fire die and clean out the firebox. (I know a lot of people don't do this but I'm a newbie). Anyway, I found two cracked firebricks on the sides. Am I burning too hot? Should I replace them? Magnetic temp gauge on top is usually around 300-350 degrees, max. Also while I had the bricks out I found lots of ash behind the steel plate that supports the back of the bricks. Is this normal?

They're only cost a couple of bucks so I'd replace them. If you haven't added another course on top of the originals, now would be a good time to do that too. I own the TLC & it makes loading much easier & lets you bank more coal towards the back.

Don't worry about the bricks, as long as they don't have missing pieces or will fall apart. If you are concerned a good lumber yard, or massonry sales place will have the bricks for a dollar or two each.. they come in thick and thin sizes..

A few cracked bricks is normal. I would not worry about overfiring the stove.

I've been running mine with a cracked brick since day one. I tried to repair it with some fireplace mortar, but it gets way too hot in there for anything to bond.

The bricks just keep the blazing coal off of the steel, which would probably glow cherry-red & warp if the brick was missing. So, as long as the crack isn't big enough to allow white-hot coal to touch the steel sides of the stove, your ok.


In case you didn't hear my story of how that brick got cracked..................... :oops:

When I picked up my stove, I left the house in a hurry & forgot all my tie-down straps. Luckily, there was one in the truck that I keep 'just in case' -- good thing! So, long story short, the stove got a strap around the pallet it was sitting on.........but nothing on the stove itself, except the metal band straps holding it to the pallet. So you can probably guess where this is going...............

.........driving a little fast........road comes up unexpected.........jack on the brakes to make turn..........BAAAAM!!!

Yup, right into the front of the bed of my brand new truck.......all 530lbs airborne!! :lol: I can laugh about it now........... :oops:

If I were still driving my '94, I would have been severely injured when the stove barreled into my cab ----- could have been ugly! :shock: Surprisingly, the new trucks are much tougher now -- that was proven!

Hahaha Smitty, don't feel bad. I picked up some really big Anderson windows off the side of the road once and put them in my GMC. I was too lazy to figure out how to close the bed so I just drove off with them and the tailgate open. I got a tenth of a mile and had to stop in the middle of a line of cars at a red light. A dozen cars behind me. When I stepped on the gas my truck drove right out from under the windows and they dropped straight down. The crash was awesome. Then a cop came and I expected lots of tickets. The cop was cool and told me about a similar bbq grill incident that happened to him. Some people including an off duty emt lady got brooms and helped me bag the glass and off I went...

That's funny. My brother found a brand new, in the box hospital bed in the middle of the street one time. All he needed was the mattress. :D

I make a habit of installing new firebrick at the beginning of each season. All 14 of them. And yes, some of the new ones crack before the new year. They are cheaply made. I understand there is different qualities of firebrick but I have yet to find the good quality.
The local brick & mortor yard will stock the firebricks.

I saw some firebrick at Tractor Supply Company. Not very expensive, but I can't vouch for the quality.

I got mine at the local overpriced stone center. I just redid them with the "keystone" shown cut a little bigger than the first one I did, to keep a tight fit all the way around. I had to trim a little off the bottom of one too, the grate was in the way for some reason. Stove is ready to go again.
