Clean Burn - Lid Stuck/w Rutland?

corey24

So after about a year of cooking and smoking on the egg I had a lot of buildup and it was time for a clean burn.  After cooking the other night I let it rip....the temp got up to around 1200 degrees which i figured no big deal because I don't have the factory gasket anymore I have the upgraded Rutland. In the cooldown process once it was down to around 400-500 I was going to open the lid to see how clean it was....lid stuck.  I pulled harder....like really stuck....like lifting egg from table stuck.  I went to bed and said I'll try it in the am.....next morning...same thing.  I got a puddy knife wedged in there and worked it around till I was able to pry it open.  Opens and closes good now, gasket seems fine (other than hard and crunchy).....I'm just not sure what made it stick?  Think it was excess Permatex that got hot and bonded to upper lid?  Just thought I would let you know Rutland can stick....

I think we may have just found our Friday Night Thread....

I was hoping the one about smash burgers would be the friday thread

i think it got buffaloed

Not sure it was the rutland, my vote goes to the permatex.  I dont wrap the therm anymore.  I did a few times because I thought it was pretty awesome, but I believe you can clean all the crud you need from the egg going about 700 dome temp for 2 hours.  I think the lump runs out at that point anyway.

It is probable that some Permatex that oozed out on top of your Rutland during your application became pliable causing the sticking. And when you say the gasket seems hard and crusty then that confirms my suspicion as the Rutland withstands 2,200º so a simple 1,200º at gasket level didn't cause it to be hard and crusty.

@RRP, maybe this guy is Wes Johnson.....

If it really was that scum ball then I would have told him to take a sledge hammer and whack the dome just as hard as he could swing it!

My only guess would be the Permatex....just didn't know if this had ever happened to anyone before.

What would cause it do by harder than when I first purchased.  Just time....elements....?

How was the 1200º determined?  Its hard to estimate high temps without a measuring device. Once you take a thermometer out of range its really not very useful.

Agree, it was a rough guess based on dome thermometer.  I got caught up with supper and forgot to take it out for clean burn.  It wrapped around to 300-400 so that was a rough guess.

I just had another thought. Besides the Permatex the culprit may have also been the creosote that was the build up inside your dome. As it got hotter some of it may have melted and leeched on the gasket before the rest of it burnt off.

Good point, but I know I've hit 1,200º before using my 200-1,000º  Tel-Trus.

 Important to note that the scale on the Tel-Tru high temp is not linear.

A clean burn is a waste. Scrub the inside with a ball of foil or a brush. Smelting iron is better accomplished on other apparatus.

@RRP Tell him to hit the base. It cost more.

Can you document the 2200°?   I’ve seen the highest of 1100°.

Can I document the @2200º ?

Well Rutland corporate technical folks told me that many years ago, but let me find it somewhere and I will post the link.

Carolina Q

What difference does it make? What are you cooking that needs 2200°??!!! My Rutland as been on my egg since 2009. I have baked pizzas at 900°. It's just as good as it was when I installed it. Ron's has been on his egg for several years longer than mine!

I just checked my tube of PermaTex and it states max continuous temp of 600 degrees and intermittent of 700. There's likely a bit of wiggle room there but likely not more than 100 degrees. This leads me to believe that it was the PermaTex 'melting', then oozing through the gasket and bonding to the top dome when the Egg cooled.

I will be keeping my clean burns at 600 from now on. It's also easier on the firebox ceramics.

Just a quick look on the Rutland website says this:

Thanks @HeavyG for not calling me liar! But I still contend I was told 2,200 degrees by Rutland years ago. Just the same I plan to call Rutland technical support tomorrow and I will hence forth change my pat answer of 2,200 degrees to whatever they say. I will even try to receive an email.

Meanwhile I just Googled "melting point of fiberglass" and the answer is 2,075 degrees so I wonder if the Rutland link you posted refers to the heat tolerance of any or all of their adhesives and not the gasket material itself.

I think it is important to remember that only the tiny amount of the gasket is inside the BGE subject to the direct heat. And besides that I question if a BGE is even capable of reaching 2,075 degrees.

HeavyG

This is from a Rutland product catalog and the 1000°F pertains to the gasket material:

From the same catalog, the info for the gasket cement they recommend which is rated for 2000°F:

Makes sense that the adhesive would be rated for a higher temp than the gasket.

+1. What’s the point/need of all these clean burns?? I think I did it once too, but haven’t for years.  Grub still turns out well, despite that.

People made gaskets out of this permatex material and never had issues.  Don’t think it’s the permatex or the gasket but maybe a sloppy cook who’s gasket might be covered in sauce that caused the dome to adhere to the base.

I believed that from the beginning but was trying to give the guy the benefit of the doubt! It just seems odd that in the 16 years I have been providing this service with at least 10 or 11 of those years suggesting the use of Permatex to adhere the Rutland that I have never heard the problem reported by the OP.

“Never” have had a issue with mine with your suggested install. Thanks RRP!
