Hello again,
I have just gotten my EFM350 plumbed up and have a few questions:
1. For guys who are running their boilers without a jacket, like mine, where are you mounting the WillBurt timer?
2. Should boilers be on their own separate breaker?
3. Can I tie into the oil boiler 115V wiring at a junction box, and add a switch to change from oil to coal?
I may have more questions as I get further along in the install.
Thanks,
Joe

From a code standpoint I'm not sure. From a practicality standpoint (you will only be running one or the other), both can run off the same breaker.JRDepew wrote:2. Should boilers be on their own separate breaker?
That's what I did.JRDepew wrote:3. Can I tie into the oil boiler 115V wiring at a junction box, and add a switch to change from oil to coal?

There are some pictures and videos in my original install thread: It's Alive!
I have a lot of other pictures available, but there are multiple examples of the EFM manual saying one thing and me doing another.
How about starting a thread to document your install? Pictures are very helpful...if you have specific questions just ask.

Look in the efm 520 manual online. It's pretty clearly illustrated for coal/oil switching.

Rob,
The max ash pan that I could fit through the door is 9.5" high, 18.5" wide, 20" deep. I modified the base a little when I was fixing it up, and my ash funnel hangs a little lower than intended (and lower than originally on the EFM350). I am thinking about getting a 1 bushel tub and taking 2 inches off the top, but I am still looking for a deeper rectangle/oval tub that will fit.
Dave at AES just lets his ash fall into the base, then he uses a shovel to scoop it out. How many people are doing this?
Thanks,
Joe

Joe,
When I had a 900 I let the ash fall into the base. The base holds a lot, so you don't have to empty it as often.

Only those that don't mind dust in the boiler room...that might be a tough sell if your basement is even partially finished.JRDepew wrote:How many people are doing this?

I was reading the answers to the questions in your post on this thread.
I had to laugh to myself as every answer is the same for me! Maybe a few more below...
Floor joist even! hehe. funny.
on the breaker question I have a switch for that also to switch from Oil to Coal, Only one breaker.
And also a switch for my Taco 503 Relay that controls my 3 water zones.
And Finally Also A switch for Boiler Aquastat override. Only really used on startup for the season so that I can run the blower until Boiler water temp reaches low setpoint and then I switch override off and let Aquastat do the rest.
Once you get it tuned in you'll be ready. In 5 years I have never had 1 outfire. They are awesome machines.

When shoveling ash from the base of the 900, I found the chimney draft took care of the ash cloud in the boiler, and laying the shovel in the bushel basket I was using (i.e., don't let the ash drop through the air) produced minimal ash in the room.

I was given a L6081 Aquastat with this boiler (along with the willburt timer), is this sufficient to run the stoker/circulator? The only diagrams in the EFM manual showing the L6081 are for steam. How would I hook this up?
Thanks,
Joe

You could use the L6081 to maintain the boiler at a specific temperature, and have a high limit control to make sure the doesn't overheat from timer cycles...but you can't do that AND control a circulator. If you intend to just circulate 24/7 between the two boilers, that is no big deal...but if you want the circulator to turn on and off with heat calls then it will need to run off a different relay (or get a triple aquastat).
