Recommended platform under base?

What is the recommended height of the platform under the base of the DF-520? Are bricks in the corner recommended. What is the maximum height to best position the coal worm?

Thanks,

Dave

4 " Blocks under the base will do one on each corner are you using a 55 gal drum for a Hopper or feeding out of a bin
it really does not matter on the heigth The Auger once inside the pot it will be at the correct height some People like to
Put the drum on blocks to get closer to the bottom of the drum so you can get more coal in and the Auger can Pick up
more coal MyseIf I like the space between the bottom of the Auger and the bottom of the drum That way the fines have some where to go besides up the Auger and into the Pot Look at the link below it will give you a idea feeding out of a bin same as the drum http://www.efmheating.com/manuals/DF520%20Manual.pdf

I used bricks that were 3.5" thick under the DF-520 base and after installing the worm found the bottom of the worm barrel to be 5" off the floor. This is too high off the concrete floor for the large bin I planned to build, so will either have to lower the boiler or raise the floor of the bin. Maybe build sloped floor in the bin to funnel the coal and drain the water? For now I am using a barrel so I raised the barrel with bricks. The DF-520 installation I was referencing used a poured and leveled concrete slab that was 1.5" thick. Hindsight I would do this rather than bricks. I attached a picture of the 96 gallon barrel for the coal bin.

Hi Dave....I now see how the "barrel bin" is setup. It's quite simple. I wanted to set my coal bin up so that the auger is in the recommended dog house but I don't have enough room....so I'll be using the barrel bin.
I know this is a question packed with variables....sq ft....thermostat setting....insulation....etc...., but how long....hours or days....will a 96 gal barrel last on a typical 20* winter day? I have an old drafty 3200 sq ft house with 4 zones & baseboard hot water system. Based on my annual 1600 gal of oil history, I'm guessing I'll need 9 or 10 tons of coal throughout the year
I'm concerned about how often my wife will have to refill it if I'm away for a few days.

I use a 55 gallon drum, it holds 450# of coal mounded up. That will last me almost 3 days with 20 degree weather and my house is very old & inefficient. I don't ever let the bin get below 1/3 full so I fill it more often. Your 96 gallon bin should last 5 days easily, but plan on ashes heaped over the top of the bucket. I would plan on having someone fill and empty every day durng the winter, it's easier that way. They have to pull the clean-out lever every day anyway.
