I just placed a bead of High temp silicone in the groove for my door ,and then placed the rope seal in the groove.This was to help hold the rope in the channel.I actually didn't even need it in there.
We install rope seal like this in our heatreating furnaces at work ,and they cycle 48x per 8 hour shift 7 days a week.(without the rtv in the door)That has worked on those big Carborizers for 50 yrs so why not stick to what works?We only change the rope seal if we start to get a slight leak.They are pressurised atmosphere so if they start to leak you will get some flame starting to lick out the door gasket.
I have no experiance using the rtv to make the seal on the door frame.I have read where a few guys have a had to dig thiers out and redo it.I don't see what is the benefit of it.I know it would be a heck of alot easier to pull a rope out and put in a new one in about 5 minutes,Than scraping rtv out of a channel and then having to pump the channel full.Then trying to keep it flat as it sets up to make a good seal.I know it has been said to use wax paper and just lightly shut it.I see that as lost time and more hassle.Plus if its cold out and you need the OWB running your hosed.
I say rope seal,Adjust the door as the rope sets overtime.Then if it fails rip it out, put in new,throw another log on the fire and go back in the house
