DF-520 Installation Pictures

Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

Hello,

Here are a couple of pictures of the DF-520 after several days working on the installation:

I'd put a bag over the head of that oil gun :lol: :lol: :lol: Scott
I think a man does what he can, untill his destiny is revealed. Right now that is trying to sell my EFM plate boilers in 520 and 700 sizes.

Sa-weet! Looks good. Did you do the install yourself? It looks neat & clean.

Maybe put a cap on that upper valve with the butterfly handle? If someone hits it it'll be a hot shower.

Looks like a 6006 is being used for outfires. Very neat install.

Freddy - I have a HVAC guy helping with the installation as its a big job. I under estimated the initial effort for the setup, installation, and operation of the unit. However, I enjoy these projects immensely. Next house will have the layout better suited for coal delivery. I am currently planning on storing the coal outside on pallets under a deck, and fill a 96 gallon drum as a bin for the first year. I originally thought about building a 8' x 6' bin with coal shoot to the outside, but then would not have room for my woodworking machinery.

My folks installed a DF-520 when I was younger (30 years ago), and it didn't seem like it was as much work back then to install! :-) They live in PA where its possible to have coal delivered right into their coal bin. Here in MA its mainly bagged which makes it more laborious to operate a coal boiler.

Stoker-man - I did install the L6006A, and hope it works. I want to set this up for my parents DF-520 since the flame out occurs often on his system during the summer, and ends up with coal in the ash bucket at times. I should have the heating zones plumbed and wired soon so I can test out the coal operation.

Thanks for the feedback!

Dave

Can't have that happen! It would be better to carry 5 gallon buckets each day than to give up any tools!

The install...it's that type of thing I say "You do once and it's done". For sure it's a bunch of work, but so well worth it. You'll be happy when it's on line.

I see what looks like a 6006 on your cabinet, but how is it measuring temperature there? Is there a well tapping there?

I have to install our stoker and our waste oil boiler in the warehouse this summer for our showroom. I might make a thread about this project, with installation pictures. It might be a good time to show a bin being constructed. I get calls about this mystery all the time. I'm going to make it from pressure treated plywood using torsion box construction. That will keep the walls about 2" thick.

Stoker-man,

There is a well there for the L6006A aquastat, and have wired it to prevent the stoker from running if the fire goes out. I haven't tested it yet, but hopefully it will work out.

Using torsion box construction with pressure treated plywood for a coal bin would be a great design. How do you plan to construct the torsion box grid? Finewoodworking(.com) has some plans for creating a table top using torsion box construction, and assuming this can be applied to creating walls for a coal bin.

I read about torsion boxes for the first time in Fine Woodworking back in the '80s. My first experiment building a torsion box shelf was for a custom bedroom cabinet set with a shelf for a TV set. Since then I've used them for doors around my outside building on my property. You can take 2 sheets of 1/2" plywood and some 1/2" sticks and glue and screws and make a door that is perfectly flat, won't warp or sag, and can probably be used as a bridge to drive a truck over. The door on my root cellar has been there since '89.
