So I just set up my combi system exactly like this. When I look in the book, it only shows 2 wires needing to be connected to the sentry zone valve(common and normally open). My sentry zone valve states it’s normally closed. It looks like you have more than 2 wires connected to the valve. What else should be connected?
@@JimSperanza that’s what I thought. Looks like you have more than 3 connected which I started to wonder. In the book, it states sentry should connect to normally open, my valves are actually normally closed so I’m assuming that I use 2 wire and just do common/nc, correct?
Great video! I noticed you didn’t use temperature sensors on the return and supply for the heating system, like you have done on other systems. Is there a particular reason?
About 150 lbs. Yes easily can mount it with two people. Best way is to use a temporary 2x4 ledger board to rest the bottom of the system on until the plywood is lagged to the wall studs. Then the bottom 2x4 can be removed.
Great installation loops , I love it .
We're do you hook up the fresh water in the system?
@@erwinperez2889 there is an auto fill connection on the bottom.
when usig hot water, does it stop heating - Is there any boiler which heats up both at the same time, hot water and baseboard heating
@guess313 all combis work this way

I only have 2 zones by the way and both stats are only 2 wire setups
@Djbigb8092 you only need two wires when connecting to the navien.

The supply and return sensors are used for the variable speed delta T circulator. This system uses a fixed speed circulator.
Jim, looks great. What is the total weight of the system mounted on the plywood? Two people can 'easily' mount it?
About 150 lbs. Yes easily can mount it with two people. Best way is to use a temporary 2x4 ledger board to rest the bottom of the system on until the plywood is lagged to the wall studs. Then the bottom 2x4 can be removed.
Just curious why did you cap the top of each vertical run?
@BeeBombard allows for future zones to be added. Some customers want that option.
Nice little set up! Thanks for the video.
I have the same piping i sill like to know hoe to wiring the zone valves
What size and model is that boiler?
NCB-240/110H
