What adapters do I need to connect this into existing single wall 8" black stove pipe exiting from a wood stove at one end and into the 8" masonry chimney hole at the other end?

Answer:To clarify, does your masonry chimney have a non-combustible clay or terra cotta thimble that you are venting the system into? If it does and the chimney is fully lined, you would not need to use the Class A chimney piping. Standard installation is to run single or double wall stovepipe from the stove to the thimble. If the chimney is far oversize beyond the outlet of the stove, you may need to use a flexible chimney liner to resize the chimney.

Does this take a stainless roof flashing and top cover? What are your recommendations?
By Collin C. - NFI Master Hearth Professional on May 19, 2014
Flashings and caps are available to be used with this product line. Most flashings are actually manufactured from galvanized aluminum, since they are not directly exposed to combustion byproducts. If you would like to provide the pitch of your roof, I will be happy to recommend the proper flashing. The twist lock termination cap that works with this model is the SuperPro All-Fuel Deluxe Chimney Rain Cap - 8-Inch Inner Diameter

I am looking to install a Keystoker A-6 coal boiler in my garage with a steel chimney stack going straight up through the garage roof. I've been reading mixed reviews on using a straight steel chimney for a coal boiler. Will this product work for this? Is the warranty the same for coal burning? I've looked at Olympia 316L all-fuel stacks as well but so much more expensive. Any particular reason for the price difference, I know they boast a "forever" warranty.

Answer:There are 3 primary grades of stainless that are used in Class A chimney construction. From lowest corrosion resistance to highest, those grades are 430, 304, and 316. The 316 grade is commonly used in conjunction with titanium to make 316Ti and 316L is a low carbon version of standard 316, giving the material higher tensile strength under high temperature conditions.
There is a significant jump in cost between the manufacturing process of the 304 and 316 grades of stainless, hence the increased price of the Olympia chimney. The 304 material is marketed as an "all fuel" grade that can be used with any solid fuel burning appliance, including coal. However, the very high temperatures achieved by a coal boiler will cause the material to age more quickly than 316 grades. Depending on the amount of coal burned, it is not uncommon for the first couple of sections of chimney to need replacement after 10 or 15 years, as they are subjected to the most heat. The 316 grades are indeed a "lifetime" chimney and should never need replacement.
