Planning to buy a Vermont Castings Encore Non Cat but not sure if my house chimney height will work.

House is contemporary open floor plan split 3 levels, with the LR, DR, kitchen on the mid level, bedrooms/bath on the top level.

Existing chimney is brick, located in the INTERIOR in the middle of the LR room, not on the exterior perimeter.

Wood stove to be located on the existing fire place hearth, rear exit with 6" optional collar (usual size is 8"- have to stay 6" due to chimney size)pipe with T connector bend thru the fire place with stainless steel liner all the way up the chimney. Bottom of wood stove to top of chimney exit is about 13 feet. VC exit discharge is probably about 2' 6"

Intend to use the VC Encore with the doors closed.

House is leaky with all year round window air conditioners leakage.

No real house exhaust except for bathroom exhaust when taking shower.

With the interior chimney in mind, would the height work ok for chimney draft?

Would extending the liner discharge up a couple of feet make a difference?

Appreciate any insight . thanks

You should add a couple feet at top if possible since you are definitely on the cusp of having too short of a chimney.

You cannot just run the single wall liner out the top. However, here are somean options - there may be more.

1. Use a unit like the cast classic extendaflue - you can buy just the castings and run the pipe up through it.

2. You can build the masonry chimney up and reline the extension
3. You can switch to double wall pipe at the top and run a section of insulated chimney (noteL must be supported correctly, etc.)

If you have interest in the Extendaflue, that is an invention of mine - email me at [email protected]
 
Craig whats that about 10 posters the last month lacking minium verticle rise? That extenda flue is a good solution.

You need 16' verticle rise above the flue collar to achieve satisfactory results, a foot or two more all the better.
AS Craig mentioned, there are 3 choices extenda flue, build a taller chimney, or extend from the liner class a chimney pipe
Craid is also correct to caution that the Class A pipe needs proper support. It would need support from the metal chimney cap.
If taller than 4' cable or guide wire system should be employed.

BTW great choice the non Cat Encore ..7 grams is the cleanest stove ever tested b to EPA standards
