Sorry for lack of updates, had some automotive issues over the weekend. Been gathering info and parts though. As much as I would like to buy local, many of the basic items I need are nearly double the price of pexuniverse...so, I am filling my digital cart. I should have everything roughed in by the time I go back to work wednesday evening and will hopefully be able to light the fire this weekend. Quick question. My output and return/drain bungs are 2 inch. Are you fellas running 2 inch pipe or bushing down right at the boiler? I have 1 1/4 ready to go and inch for the bypass loop, just never really looked at the size on the boiler. I read 1 1/4 in the manual and ASSumed...

If it were me I would keep the 2 inch for near boiler piping and bush down after all the bypass piping was done. That's what I did with my KA6 (it was 1 1/4 rather than 2) I think you want to keep the ratio of 2 inch to 1 inch for bypass loop. Hopefully others will chime in..

Thanks! Its just odd my manual mentions nothing about 2'', it just recommends starting with 1 1/4 and using inch for the bypass.

I bought mine used so it was bushed to 1 1/4 at the the boiler when I got it. I just assumed it came that way because that's what the manual states.

If you can hold off a while I'm sure others with more experience with a KA8 will chime in.

Yeah, he said 1 1/4 would be fine for my application. The kb8 is a serious boiler, probably meant for greater things than what I will use it for, but I have room to grow in the future when funds allow radiant in the floor.

It is a serious boiler. I think your NET BTU's are more than my GROSS BTU's! :o

I would use 1.25" for the supply/return piping and 1" for the bypass. 1.25" piping can move nearly the max capacity of the boiler at a reasonable supply/return differential.

If you want...run 2" from the supply tapping to the air scoop, then reduce to 1.25" after that. The larger pipe will "slow the flow" and the air scoop will be more effective. Not necessary, but a nice "twist" if you don't mind a few pieces of larger pipe.

I have all the pipe for exactly that, just have to wait for my pexuniverse order to get things roughed in. 1.25 ball valve locally is over 20 bucks. Web is under 10. I will wait to save some cash. Getting excited though, got the domestic cold side and boiler fill fit with galvanized, just need mixing valve to tie it together.
