Committed to buying a Keystoker KA-6.

PostBy: Boots On: Tue Apr 08, 2014 7:13 pm

I am going to pick up my New-to-me KA-6 within the next week. Installing it will be my summer project. What tips can you help me with to make my system better? I will be completing the install my self. My current thoughts are around building a "manifold" for the return and supply, I think I want to use black Iron from the boiler to my "manifolds" the reason for this is the rigidity that the iron will give. from the Iron I will install a ball valve then a circulator flange, from the opposite side of the circulator will be a second ball valve then copper throughout the system. Also, what should I do for air elimination? What are the befits of air separators vs. air eliminators vs. Air scoops? what do I NEED? I noticed that in some of the pictures from the post your boiler thread http://nepacrossroads.com/about19903.html some of you have air separators on every zone! I this necessary?


Some notes on the system.

Keystoker KA-6 heating 1500 Sqfq. (yes, I know it's "over kill" but I will be adding more load in the future that the KAA-4 is not rated to handle.)

The KA-6 will be a "stand alone" unit. My current oil boiler is junk.

I will ultimately have 4 zones, Main house, Addition, Garage, and basement. at time of Install there will be only 2 zones, The main house and the addition.

I'm sure I will think of more, but for now that all...

Think about the location of the boiler and coal bin. The auger I use to feed the hopper is the second best investment after the KA 6. No more buckets to dump and no black coal dust.
I have a cover over the hopper and the auger feeds into the cover.

do you "manually" turn on your auger to fill the hopper or do you have some type of automatic system? The way my basement is laid out I'm not sure I have much room to install a coal bin of any great size into the basement, but there is a window near the boiler. I have often fantasized about building a coal bin outside of this window and using the window as a "chute" of sorts. Maybe I could run an auger from the outside coal bin through the window and into the hopper...... :gee:

It isn't automatic, yet. A switch near the hopper. I have a plexiglass lid over one area of the hopper to see the coal flow.

If you can build a coal bin outside and have the coal fall into the hopper that is ideal.

I added a second flow check valve in the return line just before it joins the bypass loop. That keeps hot water in the bypass from convecting up into the return piping.

Coal "falling" into the hopper is probably out of the question, but some type of auger or vacuum conveying system is not. I would have to shovel the coal from my trailer into the bin but once it was there I would not have to touch it again. that's better than carrying it into the basement by the bucket full.

Good idea, I have yet to decide what type of system I will install. I still have a lot of research to do. I've read and think I understand the principles of a Primary/secondary system, And that can be accomplished with a very neat/tidy looking install, and they look relatively simple (assuming you get your T spacing correct). I have also yet to decide if I will be using Zone valves or pumps per zone. I really need to head over to the "Venting, plumbing, Chimneys, Controls, Coal bin" sub. and start asking for recommendations on research material.
