I ran across this and thought it would be a good read for the wood burning people on here. It does have a lot of good information if you read the entire link.

JOB - thanks for posting the link. I don't have time to read it in it's entirety right now, but I bookmarked it to read in the near future. Most of the articles that I read about this subject let me know what I've already done wrong. :~)
 
A big thank you for posting the link. I am like PJH. Too much to read all at once, but I will be back to read more later.
 
From what I have read the reason these outdoor furnaces (some people call them boilers)fail early is because they may not have installed a very expensive ThermoBloc valve pump assembly at the return line to the boiler. Just a guess
 
Premature OWB failure is caused by low operating temp.Condensation will occure in an outdoor unit at 140F and below. You don't need an expensive control unit to maintain the 140F minimum. A strap-on aquastat installed on the supply side of the boiler connected to a 3way valve, to cut flow to the house, @ 140F and recirculate it back through the boiler unit via the boiler circulator pump, until the boiler recovers to a reasonable temp. I set that at 160F. At that point the 3way will open the supply loop to the house again. I have that manual, you posted. I got it from my Solar heating supplier. I am a retired factory trained tech for Econoburn, and ProFab wood gassers, and Harman pellet heating appliances.
I have an older Royall addon boiler in my shop/garage that heats my entire house and shop. The buffer tank that I have could be bigger (210gal.), but works well over night to stablize the system temp. We haven't used a drop of heating oil in 3 years. Been burning the fuel in the tank in my Kubotas.

You obviously do not need to look at what I posted. It appears like there is more than one way to protect a boiler from premature failure. I am not a factory trained tech for boiler installation and repair and thought most people on here were not also and the information might help them. I know it helped me.

I like this site because there are a lot of people on here who will share their skills and knowledge to help others.
 
There is a great deal of great info in that manual. I refered to it very often, back when I was working full time.
Any one installing/upgradeing any type of hydronic heating system should have a manual like that.
