Shutting the Boiler Down

Shutting the Boiler Down

PostBy: kstills On: Mon Oct 24, 2011 4:04 pm

I hadn't given this too much thought, but I have to re-plumb part of the system and need to shut the boiler down.

Is there a procedure for safely doing this, or does one just pull the coal pile into the ash pan and snuf it out?

Just shut off the electricity. I'll die on it's own in about 5 minutes.

Is this for the air at the top of the boiler? If so do you have valves to isolate the boiler?

Well, speaking with Matt today, I'm going to move the 6006A over to the supply side of the boiler. That should solve the problem of the high delta between the high and low limit, and also remove the expansion tank line from doing whatever it's doing during the DZ cycle.

It won't be a big deal to plumb, I just have to add a tee and screw in the aquastat, but I have to dump the entire system one last time. Truth be told I have a very very very minor leak at the union off the boiler, so I'll fix that at the same time.

I'm going to run it until Saturday, then make the switch. I'm going to have to re-set my rheostats again, so I'll need a few hours to make sure everything is running right.

Love this boiler though, house is toasty warm (ok, it's not that cold yet, but the DZ cycle is keeping the house at 70F by itself) and it's so much quieter than my old oil fired boiler.

That's a good plan. If you're going to dump the whole system, I think you'd be better off just killing the power and dumping the coal into the ash pan. Just make sure you put the starter ring on the grate so you don't empty your hopper. Matt is always full of great ideas and willing to help, I feel bad when I have to call him. They really do put out an outstanding product. I guess he can add us to his growing list of happy customers.

For those considering making "the switch" to a stoker boiler, the noise of operation is not to be overlooked. My EFM is almost undetectable from the room above it. With a tv on, or any amount of background noise, you can't hear it at all. It is so much quieter than my oil boiler, I think my wife would have ok'd the install even if the savings was considerably less. AA boilers aren't as quiet, but I don't think they are obnoxious either...a little pipe insulation on the auger tube (and buck size coal) also goes a long way to quiet them down.

Back to the topic at hand, I agree that mounting your aquastat in the supply riser is a good choice. If there is a bypass between the supply and return, the "tee" should be installed before the bypass.

I'm not sure I'd go this route dumping the whole system, he wants the boiler cold so there is no thermal shock.
5 minutes isn't enough time for this boiler, I run my timer off for 15.

I pulled the coal off the grate, then tripped the high limit to run the circulator. That took the temp of the boiler under 100f.
