A chimney cap is required where the pipe terminates above the roofline. It is important for not only preventing rain & debris from getiing into your chimney but to keep critters from creating a home in your chimney pipe. With out a cap you could end up with a chimney fire due to debris and animal nesting material or a critter finding its way into your stove.
The DuraTech Chimney Cap is made of stainless steel and designed to twist-lock on to DuraTech chimney pipe. Removable screws allow for cleaning of the chimney system. This cap can be used with or with out the optional spark arrestor. Depending on your local code you may be required to use a spark guard for your installation to be up to code.
A ceiling support box is designed to support chimney pipe and provide a positive connection between your chimney pipe and stove pipe. The DuraTech 11", 24", and the 36" support boxes fit between standard 16" on-center joists and most manufactured home applications. DuraTech square ceiling supports will support up to 60' of DuraTech double wall chimney pipe. DuraTech square ceiling support boxes are not compatible with DuraPlus triple wall chimney pipe.
You will need to choose a DuraTech ceiling support box based on the pitch of your ceiling and whether you are using single or double wall stove pipe. Use the chart below to determine which support box is appropriate for your installation.

Select roof flashing based on pitch of roof. For example, a 6/12 pitch has a
vertical rise of 6" over a horizontal distance of 12".
For metal roofs, make sure you choose one of the below models.
