Installation of Regency insert

Looking for feedback on a couple of things: I'm replacing a 20+ year old insert with a Regency 3100. Dimensionally new and old are very similar.

The old insert was installed with an 8" stainless chimney liner, and the Regency has a 6 inch opening which according to their manual, mandates a 6" liner. What happens if I use a 6 to 8 inch increaser? (I assume going directly to an 8" would be inadavisable, as it would create a ledge around the 6" opening on the insert.)

The salesperson where I purchased the insert was the one that recommended this solution. To compensate for the expansion of the gases caused by the increase in diameter, he also suggested using a ceramic blanket around the first several feet of the liner.

Trying to avoid having to reline the chimney. Any feedback would be appreciated.

The suggestion by the salesman is acceptable and there should be no problem. This would allow for full use of your insert.

The ceramic blanket is a good idea as you don't want the gases to cool too rapidly once vacating the firebox. Hope you have room to do this.

You're right, relining isn't cheap nor fun even if you do it yourself!

Good Luck!
