better effeciency

[Bakedcorn]

Well I wouldn’t have plumbed through the LP boiled your keeping that hot and some heat will be lost there its like having a radiator there. Yes its good for loosing heat during the warm days but your loosing heat on the cold days when you want it. I plumbed my gas boiler in but I pump around the boiler with check valves

How often do you clean your boiler tubes the ash should be cleaned off every 2 to 3 weeks

Use a pipe cleaner o clean the ash out of your manometer tube port on your chimney pipe. When you take off both tubes the oil should read zero you also have to mount the thing level.

I’m not to sure what else to recommend. I have been watching my stack and boiler chamber temp and have been tweaking things to try to make my boiler to run as lean as I can. My gas boiler is a 165K BTU unit I have found I’m able to run my corn boiler at about 100K BTUs. I think next for me are new windows and more insulation and then I might play with the outdoor air reset every one’s been talking about.

No sweat, GT, hope you have some success. Do you think you are on top of the combustion issues now? I know you were messing around with timer and fan gate settings there for a while......

Baked makes a good suggestion about clean tubes, too--I switched to pellets as an experiment because of cost and the extra dirt they made in the tubes really impacted efficiency if I didn't stay on top of it. I'm going back to corn now.

i have not been able to find any magneteic thermometers tried tsc and lowes. the meter is level but must have been plugged and idid not know tried adding more fluid just need to drain and readjust know. i have been cleaning boiler tubes. 3 times this season first time did not let cool down and learned a very valubale and dirty lesson. i think i have the gate and timer down just unsure if keeping the timer pegged out at 12 off is more or less efficent. i never had any trouble keeping fire going until i started playing with the hi lo and dif settings. if iunderstand right the hi is temp the boiler should climb to and lo is when it will kick the blower on is that right and is the dif just the amount between the hi and lo. when i turned the dif to 15 from 10 i came home to the burn pot empty

GT I asked a bunch of dumb questions about the triple aquastat here:

http://forum.iburncorn.com/viewtopic.php?t=10372&highlight=aquastat

You may find some help there. The differential setting controls how your boiler behaves around the low setting. Look at page 10 of the manual for the triple aquastat here:

http://www.exqheat.com/images/aquastatL8124_honeyw.pdf

You'll also see that you want at least 20 degrees between your hi and lo setting on the aquastat--so your 160/175 plan will get you into trouble, as it sounds like it has. Especially with the differential at 15. I had to read that page 10 several times before it sank in. Good luck!

yea i was way off ok i think i got it know i set my high at 180 and lo at 155 dif still at 10 will try changing dif when it gets colder out. i do not want to change the dif now because the boiler would get down to under 140 before kicking into high fire if the dif was at 15. if i understand right. something new today also i got home to the boiler out and belive that was because of the hi lo settings but had tar like substance running down the 90 on my exhaust is that normal or possibly from the boiler shutting down so much over the last few days

sting i just wanted to tell you that i was not upset that you had no quick fix for me. also had i understood the insane jet power of a blow off i would have had him hook up the dump zone in the first place like he wanted instead of being so damn cheap a very valubale and entrtaining lesson sorry for the confusion

[sting]

Why should I be upset? Folks feel free to weigh in on this anytime!

Call me Paranoid??? Hummmm maybe if the 3000+ members of this web site were not all against me - I would feel different.

You didn't need a dump zone initially -- you needed a whole primary pump system - what you had was a pressure cooker - Good thing code required the manufacturer to provide an installed PRV. Codes are in place to protect you from installs like this.

Your installation is not being trashed - Its simply being critiqued - why would you post questions if it were performing as expected? I am not trashing your plumber pal -- well yes I am HE should know better and should not be a part of this, regardless of what you want - Its his butt here too!

I am going to persist to be very Terse with you as your install continues to unpack disturbing baggage.

I am really sorry to have to write that - What you have is a disaster in the wings. There is no sugar coating this.

From PM you tell me your worried because

sting i do have a peice of cement board that i put in front of the door and the garage is 22' deep not wide when the car is in there she is parked 6-8 feet away. i have no issue getting into my panel there is more than enough room there. i do not have a basement to install in and would not want the mess in the house again anyways that is why i got rid of the corn stove i had.

[gtrambler]

sting also i was not having issues with it i was just trying to burn less corn evereything was going great until i started messing with the triple stat i am guessing that is the reason for the goo in the chimney i took off the cleanout and it was not plugged just had the sludge on the horizontal surface im assuming that is from all the start and stops getting the boiler down to condensing temp. or possibly from the new corn i got

[Jed77]

BIG no-no having a solid fuel appliance in your garage especially with the car in there. I take it you have not informed your insurance company of your install. I believe you could wall off the boiler from the rest of the garage and put in a separate outdoor entrance to the boiler area.
