A:  1. Yes 2. Not sure 3. I used single wall pipe inside the house, into the wall thimble, then into a 90 degree outside that had a clean-out at the bottom. The system works very well like that and the chimney sweep was able to easily clean the whole thing last spring.

A:  1. Yes, if you follow the installation instructions of the appliance. Adapters are necessary. Please insure you follow local codes and always check with your insurance carrier. 2. If you are using DuraPlus, then the Wall Thimble needs to be DuraPlus. 3. No, chimney is limited to 30-degree elbows and no, DuraBlack can only be used in the conditioned space as the stove. Please refer to the appliance installation manual for proper venting practices and procedures. Also, if you have further venting questions, these need to be asked of the appliance manufacturer, and your local code officials.

A:  1. NO - this is against code, UL and will most like void your homeowner's insurance. 2. Wall Thimble needs to be the same brand and type as chimney, so if you are using DuraPlus Chimney, then it needs to be a DuraPlus Wall Thimble. 3. No & No - Maximum elbow in chimney is 30 degrees, no exception. Single wall cannot be used outside or in an attic, only in the conditioned space of the stove. Please refer to the stove installation instructions for proper venting practices and procedures.

A:  I used a duravent double wall 90 due to clearance required from a combustible surface. Then single wall down to the stove.
