"Hello World"
First, thanks to all the members of this forum for making it so informative.
I recently purchased a XXV with the ignorant assumption that I was done spending money. However, after discovering my ignorance via this site, its obvious that I MAY require a reline.
I've collected the following information from around the site - I hope it might also be helpful for others to see this in one place
How to determine if a Reline is necessary

Benefits of Reline

Partial reline?

Reline Costs
Risks of not lining
[My dealer - Heartline Stoves NH]
My setup
- New XXV
- 6 in flue hole into an interior masonry chimney approx 25 ft high. This was built with the house - most likely for a wood stove setup. Never used. The house is 3 yrs old.
- Flue is rectangular orange tile - approx 12in X 8in (guessing - see pic) condition looks mint
- I currently only have the 3 to 6 in converter, 2 elbows, and 2 2ft sections to connect to existing flue
It seems a reline certainly will not hurt, and I could see a lot of great benefits from it.
My questions
1. Is there any code in NH requiring a reline?
2. Do insurance companies normally require a reline to hold coverage?
3. What is the recommended reline kit?
4. How difficult is self installing a reline kit?
5. Is it worth the money in my situation?

How to determine if a Reline is necessary
[darkstar]
- The cross sectional area of the flue of a chimney venting solid fuels with no walls exposed to the outside below the roof line is more than three times the cross-sectional area of appliance flue collar.
- The cross-sectional area of the flue of a chimney venting solid fuels with one or more walls exposed to the outside below the roof line is more than two times the cross sectional area of appliance flue collar"
Benefits of Reline
[Delta-T]
-eliminate the risk that any exhaust will find its way through fissures in the clay tiles and cause deterioration of the masonry.
-reduce the likelihood of the “cold stack effect” creating too much resistance and setting off the pressure/vacuum sensor.
-reduce the likelihood that a block off plate and insulation around the pipe is poorly done allowing exhaust to come back into the house.
-makes for easier/better ability to send a pipe brush up the chimney without disturbing fore mentioned block off plate and/or insulation.
Partial reline?
[DAKSY]
You can run your pellet vent a foot or so into the Class A & seal
the area between the ID of the Class A & the OD of the pellet vent,
but the fly ash that comes out of the PV will build up inside the Class A.
In order to clean it, you’ll probably have to take stuff apart & the mess
will be hard to contain…
Your best bet is to run the 3” PV into the Class A, increase to 4” & run a
Stainless Steel liner all the way to the cap.
Reline Costs
-$589 for a 35’ 4” liner complete
-$250 liner install
-$70 90 degree
-$37 3” to 4” increaser

The recommended practice and most municipal safety code requirements call for relining with 3 or 4 inch diameter stainless steel. If you have an interior chimney in good, clean condition and with a restrictor at the top, you may be ok. Pellet appliances, by design, allow very little heat into the chimney thus the chance for condensation.
If you use an unlined chimney and have an event that requires insurance company funded home cleaning, expect legal action against someone.
