New insert has arrived and has had paint cured out in the driveway. Glad I did it outside as it really smoked and stunk!

Existing 8" flex liner has had 5-10 gallons of Thermix dumped on top of the damper block off plate, then rest of chimney insulated with loose fill perlite. Tried to pull liner up slightly today to remove existing insert and couldn't get it to budge. So, on to plan B.

Plan B is to cut liner close to outlet on existing insert, remove insert, cut liner again higher up in throat of fp and install an adjustable section of pipe to the liner, get new insert in place, pull down pipe into stove collar and secure. Have a couple questions:

1) The only slip joint pipe I've seen is black pipe like (broken link removed to http://www.northlineexpress.com/itemdesc.asp?ic=5SE-2824B#) Has anyone seen this in SS? Do I need SS?

2) What to seal joints with - furnace cement? high temp RTV silicone? no sealing?

Thanks.
 
Found (broken link removed to http://www.hartshearth.com/productcart/pc/viewPrd.asp?idproduct=4151&idcategory=518) Probably go with stainless so I won't have to pull the insert in a couple years to replace rusted out section of pipe.
