A few questions...

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

Mine is mounted on a ceiling joist.

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.

That's what I did.

Rob,

Do you have any pictures of your setup online?

Thanks,
Joe

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.

Thanks for the information all.

Where can I source an ash pan for the EFM350? I looked at tubs at tractor supply and true value and they are all too big or way too small.

Thanks,
Joe

How wide is the area that the ash tub sits in?

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.

A Dover Parkersburg #0 tub should work.: http://www.bucket-outlet.com/8roundtub.htm

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.

Ash tub... My basement isn't pretty but it certainly cuts down on fly ash when you are cleaning it out by hand versus just pulling out ash bucket... my .02

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).
