The class A should come down into the room some and then transition to a trim ring and a close clearance adaptor then go to the stove connector pipe. Also you can use a ceiling support box which should hang down into the room a few inches. The Connector pipe connects directly to the support box.

Sparky,

This is the visual to what jpt has said. If your installation look like this then you are good to go.

This is a question that does not get asked much. It deals with the clearances from single wall pipe on a diagonal. As jtp says, a ceiling support box or roof support box-type will solve this problem, but there is still the question of how far inside to hang insulated piping when using a "rafter" type support. This is a clamp which holds the pipe at the roof level and allows some to hang below. Some brands sell this as a piece of pipe with the clamp already attached.

When single wall is used to connect to these roof supports, the instructions call for 18" of clearances to combustibles on a level plane....as per the drawing below (Selkirk). The makers sell large trim rings for these applications - or, you can hand extra chimney (or double wall connector) down into the room - this will serve to reduce the amount of ceiling combustibles that must be cut back.
