How to install liner adapter to stove insert?

[stallonepanerai]

Hi everyone,

I have a rectangle to round cast iron chimney adapter for my old slammer stove unit. I am looking for ideas on how to fasten the adapter to the stove since there are no mounting holes or brackets. I don’t know if I should weld a bracket or screw directly it into the stove? I don’t mind doing either just looking for options and opinions. Below are pics of the adapter and the stove insert. Thank you very much!

I’d use self-drilling, hex head Zipscrews. Looks like your flue collar has locations for screws, so it should be pretty simple. You could always predrill the locations…

I drill and tap for 1/4 20 bolts. I havnt had allot of luck with self tappers

Drilling and tapping is an option. It’s not really thick steel maybe around 1/8” thick. I’m assuming some kind of sealant or cement between the stove and the adapter? If so what kind is recommended?

I usually apply self adhesive flat gasket to the bottom of the adapter unless the top is warped then you will need some furnace cement

Ok. Just so I understand does this area need to be airtight or no?

It should be as air tight as possible which is why I use gasket. If you let to much air in there it will hurt your draft.

Got it! Thank you

Is this the gasket you recommend for between the stove and cast iron adapter?

 

[bholler]

Yeah that should be fine

Quick question….. if I use the self adhesive flat gasket, I’m still drilling and tapping the holes correct?

Yes that adhesive will be gone after the first fire. It's only there to help keep it in position while assembling

Makes sense! Thank you

Hi everyone, I just moved in my new house.
I need to order oval stainless liner. Does the type/grade stainless matter for the liner? Which is better? Also does the liner need to have insulation around it? Just asking for clearance issues.
Thank you again for your help!

If it's only 1/8" thick (surprising) I personally would use fine thread screws or bolts, and in stainless steel...so 1/4" NF stainless, and coated in high temp never seize before installing so they will come out without breaking at a later date. Nickel based never seize is good for something like 2500* F

For wood the minimum i use is midweight liner. Light wall is ok but if you ever need more aggressive cleaning light wall can be damaged. Plus the more thickness you have the longer it will last. For an old stove I always use heavy wall.
And yes you should insulate the liner

Ok. I’ll ask the fireplace store for the heaviest gauge thickness in stainless. Off the top of your head what are the heavy gauges?
