Are those SharkBite fittings? Make sure your PEX is secure and won't move or vibrate. I had a couple valves that would leak if things cooled down and the PEX shrunk. Pulled them apart and the the pipes had groves worn in them. Replaced with pinch bands and no more problems. Good luck!

My 5036 came with a taco 009 outside. Just stripped back the insulation and connected the pex to the male ends with clamps.

That is interesting. I wonder if that just something your dealer does as a package. I bought my 5036 in early 2011 and it did not have a pump. Really it shouldn't come with one in my opinion. If you need a larger pump for your application it would be wasted.

Ya thats a good way of lookin at it.

Quick question...on the side of boiler at the hook-up...how does it come? Is it just a plug or is there an elbow, is it male or female or what??

Mine has a tee for the inlet and outlet. I'm not sure I have ever figured out why it is not just an elbow but you will be hooking onto a female thread unless they changed.

artbaldoni, thanks for the heads up. Ill be keepin a close eye on it.

HandyMark, ya that is weird they dont have an elbow. Thanks for the info. Just tryin to get everything prepared

I was just looking at my boiler and realized I gave you bad info. The bottom side of those tees are 3/4 MALE thread. When I first looked I thought I had a nipple in there.

Oh ok...thanks. Are the ports for the "out" and "in"  3/4"? If so that doesnt make much sense since everything else is 1"

[HandyMark]

I have a 5036 and nothing on mine is 1". It is all 3/4"

Both of my old Central Boiler Classic and my new Eclassic had/have 3/4 inch ports. I think most 1 inch PEX is 3/4 inch or so inside diameter anyway. 1 inch outside diameter.
I've never had a problem moving enough water through it over the years. House always warm.

My thought on those furnace Tee's, I got temperature gauges from my dealer that can screw into the end of those Tee's, so I can monitor the water temp leaving and returning to my furnace after some heat has been pulled off in my house. It cost me a few extra bucks, but I like them so I can monitor Delta T / temp drop.

1" pex isn't 3/4" inside or 1" outside. Pex is copper tubing size OD which is 1-1/8" OD.
The sidewall thickness on pex is 1/9th the diameter and on 1" pex is about 7/8 ID"

You can get 1" pex barb fittings with 3/4" threads and they are straight through because fittings are smaller diameter.
That is probably why CB uses 3/4" fittings.

That is a good idea. I honestly hadn't paid any attention to those fittings until it came up here. At first glance they don't seem very useful since there isn't a lot of room between the fitting and the door.

Love that idea, I will for surely do the same thing....easy way to keep track of the temp and heat loss!
