Stainless liner install

in THE MAIN WALL
Hoping I can get some independent info from members on the forum.
I have a 8x8 clay tile chimney approx 20 feet top to bottom three sides exposed.
With the Buderus G115 I feel I should have a liner installed.
Does anyone know if there can be problems such as moisture and do I need a tee type with a well to collect moisture.
I'm not sure the tee type can be used because the flue is not straight down but has a offset starting a few feet from the bottom.
Hoping someone can help or suggest where to go to get the correct install.
The two installers I have l would feed the stainless top to bottom and through the

    Sorry sent before finishing. They feed the liner through the the wall by forming the flex to 90 degrees.
    Really appreciate Your help.

    A liner is a must....especially w/ a 115. They typically have low stack temps.
    The tee would be nice. A good chimney sweep should be able to do this..
    Condensation will more than likely be less of an issue w/ the liner as it will take a whole lot less energy to warm up the SS vs. a thick clay tile liner.
    If this is on a north face chimney an insulated liner may be a good plan.

    Thanks Kcopp. it has been a challenge because I don't know enough to make the decision. I want to get another opinion or two before I get this done. The stainless should heat up much quicker than the clay and should have less condensation. I was hoping to get someone who did a liner and how it worked out.

    I have a 5" liner in my home. 35' unlined Center chimney though. There is a tee in the bottom.

    The Tee is a good idea, and I think it is code. NFPA 211 requires the clean-out. There are manuf, Z-Flex that I know for sure and other liner manuf who make removable snout (side outlet of tee) tees. Essentially it acts as a sump and catches debris like leaves that happen to get blow in. I lined a friends flue years ago to see how it was done and found an 8" round flue mostly plugged by leaves, other debris and a dead desiccated squirrel. The tee is a good idea.

    Yo can have a 90 Deg from the liner in the chimney and just before entering the chimney, have your tee with cap horizontaly.
