Installation Questions
I've recently purchased a Keystoker KA-8 to replace the oil -fired boiler in my home. I plan on installing it myself, as I installed the oil boiler ten years ago, when I converted from hot-air. Along with this, I plan on building a new exterior chimney to replace a deteriorated inside chimney. The outside chimney height will be around 36'. I plan on using a chimney block product ( 17" x 24" ) that looks like brick ( 3 courses each ), along with a terra cotta liner. I can't find anything on how thick to make the chimney base ( footer ). I live in western Pennsylvania. Anyone out there have any advice on this project . Should I be considering a steel chimney instead of masonry? My home is vinyl-sided frame construction. Also, I've been advised to install dual AMTROL expansion tanks with the new furnace. Previously, I had a single expansion tank installed, but the KA-8 has a 75 gallon water jacket. I had a 5 zone system with zone valves and a single circulator pump on the return side. Am I in for any unexpected surprises ?
Call you building inspector and ask him what code is for that size footing. I just built a single flue chimney, the block is 16"x16" and code was for a 24"x24" pad(footing) also make sure you're at least 4' below grade for frost.I went down 6' and made the footing 30x30, I tend to overdue things sometimes . I would build a masonary chimney before instaling a SS, masonary will out last you and the house where the SS will last about 15-20 years. I priced out both and the SS was actually more $.

You need an additional 8 gallon or larger tank. See attached gif file for the details. If possible I'd move the circulator pump to the supply side of the boilers.POSTALET wrote: Also, I've been advised to install dual AMTROL expansion tanks with the new furnace.
