The guy that sold me the boiler gave me the option of either gearbox. The early 80's ones are different than the one they use now, and the old one he had was in very nice shape - so that is what I went with.
Sweeeeeeeeet! Mine is still blocking my basement stairs. What a project just to get my fat belly between the rafters and upstairs hydronic line to get down there. Maybe I'll have it going next season, lol. I sure hope it fits down here ...
Yes, there used to be a 6 section oil boiler sitting in the same spot. The amount of soot that came out of it when I separated the sections was unreal.
I don't see a timer on your setup. Do you not have a timer? If not, does your feed and blower run consistently then? Trying to determine how much on and off time I need to set my timer at.
@@battyice thank you so much for that quick feedback! how realize that the timer depends on a couple factors such as size of house, room thermostat temperatures, number of zones, etc. Could you please let me know the approximate SF of your house, how many zones, and what you keep the room thermostats at in the dead of winter to keep the stable temperature for 2 mins on per half hour? What temperature does that keep the water in the boiler system at?
The timer just keeps the fire lively during periods of little/no demand for heat. The aquastat is what maintains the boiler temperature when it has a load on it. The timer cycle might need to be changed if you run a high feed rate. I run my stoker on 4 teeth of feed.
Nice clean setup. Great work !
Glad to see you got the DHW hooked up. Looks Great!
I didn't realize that you converted your 1981 520 to the old style gearbox. Good deal.

Very nice job on the installation👍
Very nice, simple and bulletproof!

Very cool! Such a pro installation.
Every time I watch this, I write something new down for when I redo my system.
Looks nice!
One of the best videos on UA-cam! Seriously, nice work on your setup. Did you eliminate the oil boiler?

Just go mine hooked up with oil backup

My timer is inside that gray enclosure. I run 2 minutes every half hour and have never lost the fire, and the boiler temps are stable.

Grundfos pumps?
Yes, Grundfos Alpha.
