Questions about Installing a Leisure Line Hearth Model

The end of last winter I purchased a Leisure Line Hearth from a local retailer. I had to make several repairs to the area in which the coal stove is being placed so I have just got the chance to hooking it up now.

The place where the coal stove is going was orignally used for a wood fire place insert. Before my wife and I purchased the home the freplace was converted using a gas insert. When we decided to purchase a Leisure Line Coal stove we choose the hearth model because we had the stone surrounding. Now that I have extended the hearth there is enough room for the freestanding unit to safely bear on.

After reading several of these posts and speaking with some local retailers my plan of insallation is as follows:

Coming out the unit with a six inch 90 degree elbow then into the barometic T. From the barometric T I am going to use a 6" stainless steel chimney liner to go into the old fireplace and up thru the damper. When the fireplace was used for the gas insert there was a 4 inch hole cut in the damper. So i just increased the hole to approximately 6.25 inches to allow enough room for a snug fit through the damper. Once the pipe goes through the damper place It will go up a slight distance past the damper plate and they will be exhausted into the original terra cotta chimney liner. The liner is in very good condition. I have read many different articles in regards to how far up to run the stainless steel liner up the chimney. Last year speaking with Leisure Line they said there was no need to run the liner to top of the chimney as long as the chimney is sealed enough so that no gases can make their way back into the house.

If anyone reading this can make suggestions or tell me if I am on the right path for successful installation I would greatly appreciate it.

How far 2or 3 feet
I had some linner issues with my install last year.
I got a 10 foot left over piece of 8 inch SS linner a stove shop installs and pushed as much as I could get in.
Eight feet was plenty to get past my broken linner in the chiminy above.
I used pink unface insulation rolled up tightly to fill the gaps
Worked great My Chimney has a cap to stop the rain

I planned on going approximately three feet of so past the damper. The liner on the chimney is in very good condition. I appreciate the feedback.

If your chimney is not real tall, try and go 4-5' into it. Keeping the exhaust gases laminar will help the draft, it will go turbulent once it reaches the end of the stovepipe.

The Chimney itself towers two stories and three feet or so over the roof. Therefore the overall length of the chimney is approximately 23 feet. I was going to use fire/heat rated caulking to fill in the gaps.
