Manifold Hookup for KA6

Manifold Hookup for KA6

PostBy: 218Bee On: Wed Jun 11, 2008 7:29 pm

Hi folks,

I'm putting the pieces together..slow but sure. The Keystoker is in place, more or less, and I'm planning the piping.

My Dunkirk feeds three zone, upstairs, downstairs and a Phase III water heater. My manifolds are plumbed for a fourth zone. Can I capitalize on these for the pex-al-pex hookup to the coal stoker?

The pictures show the risers on the right side of the supply and return manifolds.

Tanks,

Rick

Rick, I heated my house with ease last winter doing just what you are thinking. With a 3/4' line off a heat exchanger from an outside coal boiler. It works fine, just keep your coal boiler temp up high around 190 degrees. It appears that you have a relatively modern house by looking at the condition of the concrete wall behind the boiler. Or,,,,more better insulation. If this is true, then the 3/4" taps will work. If your house isn't insulated so well I would pipe it into the ends of your headers and increase the pipe size from the coal boiler. :) Scott

Thanks, Scott. The house is pretty tight, good to know it will work if it comes down to that.

My bud, with lots of HVAC experience, doesn't like the btu loss. Looking like a 1 1/4" union near the elbow or I dig into the mess at the end of the header.

The previous installer didn't do me any favors with the helter skelter pipe work. but hey, ya work with what you've got.

Seems to me that you can use the "fourth zone" to hook in the coal boiler. Just hook 'er up. Do you plan on keeping the oil on line?

You shoud add a backflow preventer to the boiler intake so you cannot ever contaminate your domestic water.

Hi Freddy,

Yes, I'll turn the aquastat down on the oil burner so it will be the standby unit.

I hate to handicap the coal burner right from the get go. Any idea of the BTU hit I'd be taking? So far I will have 1 1/4" steel out of the Keystoker to 1" pex-al-pex for 50' to the oil boiler then either to "zone 4" or to a 1 1/4" steel into the manifold. Seem to me we'd be pushing a lot of BTU's only to bottleneck them at the manifold. Sure would be an easy hookup though.

Thanks for your thoughts.

Swap those elbows on the manifold for tees and you should be good to go.
Set it up with "close spaced tees" the 'sting' way.
The 1" pex id is almost the same as the steel id from what i have read on other posts, so you should not be restricting it very much.

I think you'll have pleny of BTU's flowing. No worries!
