My house was built in 1910, and I feel pretty confident that this is the original chimney. I am having to widen the inside of the fireplace a few inches to allow the wood stove to fit in. I am going to need to repoint a few spots.
What would be the correct type of mortar for this job?
Also, I need to line the chimney. Can anyone tell me some general codes for lining a chimney? Do I HAVE to use Stainless Steel? Any certain thickness? etc?
I can get pictures later today. What would you like pictures of?
Chimney is 21 feet. The inside of the stove measures 22"x15"x16". Outlet of stove is rectangular - 14"x3.5".
I believe the stove is supposed to have an 8" flue, but I have seen bigger wood stoves with only a 6" opening. I am not even sure if an 8" liner would fit inside my chimney.
I called the inspector, and he said to check with one of the stores that sell wood stoves and they would tell me how it needed to be done... Well I called one of the largest in the area and they told me that they regularly put 6" pipe on a stove outlet that is 8", and that it would be fine. They said that as long as the stove was 4.5 cubic feet or less a 6" liner would be fine. My stove is right at 3 cubic feet.
As long as it passes inspections, would I ever have to worry about anything insurance wise, if something were to happen?
I have mine on a 6" flue --the stack is similar in height--I had the size figured by the engeneer at the heating supplier that engeneered the hydronic system--
I doubt if the insurance company will have an issue as you are merely upgrading an existing system.
I'm not a mason--one will check in soon about the best type of mortar--
I don't know anything useful as to the liner---I could move this to HVAC if you like---those guys (and gals) are the ones who will know.---Mike----
Starting two threads on the same subject usually get both ignored---You see, most regulars hit "todays posts' rather than go to individual forums---When they see two post from the same member it usually means they didn't like the answer given in the first post--so no one reads either---

Well, you see, my other thread was 10 days old before I started this thread. So, it wouldn't have been on today's posts, and if anyone was going to answer the other thread I think they would have done it in the first 10 days.
Oh--well if we keep this at the top someone will answer it---We have some really good and helpful HVAC types here--I would think a flue liner question would be simple enough--let's try to keep this alive--someone will chime in--(I hope)--Mike---
The exhaust opening on a wood stove or insert is usually the size that the stove manufacturer recommends for it's best performace. Some will allow you to go with a smaller diameter if you operate it with the doors closed. That is up to the manufacturer, otherwise it may restrict it, which could induce smoke into the house. There are a couple of options, one would be to use a smooth wall flexible liner which creates a 20% better draft. You can sometimes down size, and still keep the same draft. The other option would be to go with a shaped liner, such as a rectangle liner to fit into your existing flue. I have not heard of the cubic foot measurement to determine a liner size diameter, so I can't comfirm that.
R1003.11 Flue lining (material). Masonry chimneys shall be lined. The lining material shall be appropriate for the type of appliance connected, according to the terms of the appliance listing and manufacturer's instructions.
