Return lines hot, supply lines cold to warm

Just installed a complete baseboard system, NewYork brand gas boiler 45kbtu with 2 zones, should the return lines be hotter the the supply? Could my pump , pump backwads if I wired it wrong?

Are you sure you did not install the pump backwards?

Usually a wiring error will not result in the pump running backwards.

Ditto Allan's reply.

Not a wiring error... pump is likely installed backward. Happens a lot more often than even seasoned installers will care to admit!

There is an arrow on the casing of the pump indicating direction of flow.

the wording on my pump is upside down but the arrow on the housing seems correct.

Can you retake your pictures, setting Exposure Compensation to plus values (try both the +1 and +2) and/or use flash and use minimum zoom? The pictures are too dark to see how the plumbing is arranged.

You should have turned that motor on the pump. The electric box should not be on the bottom. WIRES OVER WATER is the rule!

Allan, I can see them...

Supply out of the boiler, up and then left to two zone valves.

Two return lines coming in from the right to a manifold, over and down to the pump then the return.

I believe the problem is that there is air in the system blocking flow.

And I don't see any purge stations for forcing water through the loops.

On second thought, it looks like there is a ball valve on the supply side between the boiler and the zone valves.

Turn boiler off and allow to cool to 100F or less.

CLOSE that ball valve on the supply pipe.

Connect hose to return manifold valve (there's one there already)

OPEN the drain valve,

MANUALLY OPEN one of the zone valves.

LIFT THE FAST FILL LEVER on the pressure reducing valve to force water through each zone in turn until no more bubbles appear in the bucket.

RELEASE the fast fill lever, and then close the drain.

Try it again.

Thx I think I have all the air out, I am going to get temps off the supply and return lines to confirm which way the water is flowing
