what is the correct way to be setting the boiler on. I see some on blocks and other on a slab. my boiler is a 1965 efm 520 round door , with that boiler I should have the option of three locations for the feed screw correct?

4" concrete blocks work very well...one at each corner.

The stoker can go on the left or right, but not on the front.

If you have room in your cellar and a smooth, level floor you can use a skid system.

You would never have to manually lift coal.

In order to use a skid system, with a floor auger box with removable skids with shutters and bulk bags, you must use blocks no taller than 1-7/8". This gives you the proper room for the auger to fit under the skid. EFM is the only boiler with a low enough auger angle to do this. You are lucky to have an EFM.

You would need 21 concrete blocks, 3" x 6" x 1-7/8". Home Depot sells them.

The other advantage of the skid system is you never have to worry about a blocked auger. Just close the skid gates, lift the skid off and fix the problem should it ever happen.
