hydronic heat for the barn - part 9

The weather outlook does not look good. In fact we are going to get a dump of snow, and the next few days will be quite cold. Realizing this I got all the work done on the outside of the building, as well as connecting the PEX pipes to the manifolds. When the long awaited parts arrive I would not need to go outside the building to fight the cold and glue the pipes and caulk the holes I created.

I have been too cautious in not willing to start some part of work worrying about the copper plumbing being done first. There is next to no risk by now as the remaining part entails relatively easy work. I decided to move forward in installing the combustion air intake and exhaust, as well as the condensate drain line.

In order to keep the cost to minimum I carefully planned to buy only one large diameter copper pipe. The installation requires 1 1/4" as well as 1" diameter pipes as the boiler ports are the former while the manifolds are the latter. But I have a 5-foot piece of 1" left over from my previous boiler installation. I designed my installation so I only need to buy one 10-foot piece of 1 1/4" pipe.

While I'd gone as far as I could with the copper piping installation and I have a day to identify and compile the next online order by Sunday night. As everything is a week away my goal is to able to complete the plumbing and have all the critical material on hand by the end of the month.

I was not looking forward to start doing the copper plumbing because of the need to route the pipes parallel to the back wall but at different planes for various system components. It is impossible to identify all the necessary fittings until you dive into it. Dive I did today even though I knew I need at least four more elbows. I also consider 45s instead of 90s for better flow.
