Hey all,
I finally pulled the trigger and ordered and received my insert and flex liner. I am putting a Regency CI1200 into a prefab fireplace and will be using a Magnaflex Insulflex SS insulated liner inside a prefab 8" diameter double wall ss chimney. I am looking forward to performing the install but have some final questions regarding the liner:
1. The flex liner at the stove:
The flex liner attaches to the stove adapter via three screws. I had planned to put a bead of furnace cement at this junction. Is that advisable? Will it cause trouble if I need to disassemble for cleaning or does this joint stay intact during cleaning? (The stove manual does not mention furnace cement)
2. The flex liner at the top of the chimney:
The flex liner can be secures with three screws at the top of the chimney? The OD of the flex liner is ~7-1/2" and the ID of the Chimney is ~8". So, there is a small gap around the diameter. Are three screws sufficient or should some sort of adapter be used? Should roxul or something else be used to seal that gap? Speaking of that - does anyone know where I can get a small qty of roxul (fireplace supply etc..) or do I have to special order a giant batt from Lowe's. I literally only need a handfull. Maybe I can scavenge some insulation from the unused cutoff piece of flex liner?
3. Stove
The offset adapter connection to the stove is a tight fit but it is steel to steel. Should I put a bead of furnace cement at this interface also? Again, the manual states nothing about using cement. I want to seal up everything nicely but I also want to make sure that it is serviceable.
I welcome any advice\experience you may offer! I will document the install with photos and post when complete.
