1. Identify the type of connector pipe you will be installing.
Single-wall stovepipe, which requires an 18-inch clearance to combustibles,
or
Double-wall stovepipe, which requires a 6-inch clearance to combustibles.
2. Determine the amount of the exposed cathedral support that will be
projecting into the room, as per the “X” in the diagram to the right.
3. Select the pitch of your sloped ceiling from the chart below.
4. Select the measurement from the chart below, where the pitch of the sloped
ceiling column intersects with the exposed cathedral row selection. This
will determine the measurement of insulated chimney required below the
cathedral support, as per the “Y” in the diagram to the right. The minimum
of insulated chimney below the cathedral support is 1 inch. This minimum
is required for stability of the system.
