it is 24 3/4 " tall With both Auger's short & long you will need 83 3/8 " from the side of boiler Short Auger is 48" over all
witch only 17" will be sticking out of the side of boiler you should use a long Auger with the short Auger from the center
of the Auger coming out of the boiler base will be 15.5" off the ground Once both Auger are together the Tip of the bin
feed Auger Long one will be a 1.3/4" off the ground you should put the boiler on a 4" concrete Pad or 4" Blocks
I would need to go with the very short auger. I will take some measurements and see if I would be able to install the EFM stoker. So now lies the piping arangement for two steam boilers. I could go with one main steam stop check valve on each boiler, and also cut out valves on the condensate return line and operate either one boiler or the other.
How would I go about setting the boilers up so that say I fire my coal boiler, and now it is time for work, go to work, fire happens to go out, no steam, gas boiler senses out fire, fires up and generates steam for the house.
Could I install a steam flow sensor on each steam pipe leaving the respective boiler, then install automatic valves for the return line so that the boiler that is on line and generating steam, the condensate return line valve will open for the on line boiler? Just trying to think of routes to go for the piping arangement. Any thoughts are welcome.
One other thought. I was thinking about a vapor stat for each boiler, leaving the pressure troll there for a high limit safety. Thanks all for your help.
