This morning the temp was at 195 degrees, I'll probably drop the feed back to 2 teeth. I didn't think I needed a dump zone, but on the other hand...

The problem is deciding where to dump heat when it is 90 outside. My basement is the coolest part of the house, so I just run the boiler with "bare knuckles" and skip the dehumidifier in the basement.

You could also bump up the high limit a little, 210-215F.

I may raise the high limit a little if needed. Right now there are only 2 adults in the house and we both work, so there's a lot of idle time with no DHW usage.
The cellar is 85 degrees right now!
It's amazing to me with the boiler running on the timer only it manages to create so much heat. :D
I don't know where I'd place the dump zone.

I don't remember, do you have the Rheem OF Water Heater plumbed in to thermosyphon? That would take some heat off wouldn't it?

I think that new patio needs a new hot tub or maybe a pool in the back yard.

Set the feed to 2 teeth, the aquastat settings are right where I left them, 150/200/15 diff. I timed the outfire timer, even though it's set on 1 1/2 minutes it ran for 2 minutes, which means at 2 minutes it must have been running for 2 1/2. I'm leaving that alone for now, one change at a time.

The Aero oil-fired DHW tank is isolated with ball valves and is empty. :D

Nice job with the insulation. How is your basement temperature now?

Do the 350's come with any sort of rear panel?

It's considerably cooler in the cellar now with the insulation and the lower boiler temperature. Even with the insulation the top of the jacket gets hot when the boiler is at 200 degrees.
The boiler did come with a top half to the rear jacket, I just don't have it. You can see in the photo where it would fit into the slot in the top covers and attach to the rear bottom cover. The panel for the stoker side is for a boiler with the stoker on the left, my stoker is obviously on the right side. The panels are different for right and left. On the right side install the stoker flange is centered, on the left it's offset. The cutout in the panel was offset, I had to cut it larger to fit on the right side. I have the filler panels for both sides, just have to get around to painting them and getting them installed. Just having the jacket set for this boiler is a find in itself.
I did not install new insulation behind the front cover, it already had it, but the rest is new. I somehow managed to pack 3.5 inches of fiberglass under the covers.

Have you check the temp gage yet to see if it is accurate fill a jar or glass with boiler water from the boiler drain valve stick a thermometer into jar or glass see what the temp is of water your gauge might be off .

One tooth feed might not give you enough btu output to keep the water hot enough let alone to keep the fire lit 2lbs a hr is not a lot of coal keep at two teeth and make sure it is at two teeth and set timer at 3 minutes per hr and make sure it is running at that check it with a clock or watch the timer will run 72 minutes per 24 hr period and not having anybody using water during the day the boiler will not run much more then 72 minutes a day so with your feed at 1 tooth 2lbs per
hr you will be only burning 3.60 lbs per 24hrs 2 teeth is 4 lbs per hr so at 72 minutes per 24 hr period you will be at 9 lbs
a day

Had big time problems with outfires last week, 5 times. I'll tell you about it when I call you back tomorrow.

Feed is at 2 teeth, 150 Low/210 High, timer is now at 3 min and 20 seconds every 1/2 hour. I was loosing the draft completely every afternoon, found it on Sunday afternoon with no draft, fire was dying.
Now it's OK. After the hot weather ends I'll go back to normal timer settings.

Did you check stove pipe for fly ash build up another reason you could be losing draft you need to fix the chimney for summer time use might need a liner installed

Pipes and boiler were cleaned, holes in grates were cleaned, chimney checked, everything and I mean everything was checked, baro covered with foil to eliminate loss around the flap and the cutout for the tab, all over the last 2 weeks. The draft is fine until we get into a period of warm/hot and humid days and nights. When the temperature drops during the night the draft gets going and seems to carry it through the next day.
Been running fine since Sunday when I figured it out and upped the timer.
