Hot water baseboard question

[AMontemagni]

I live in a L-Shaped ranch and I have a hot water baseboard heat system. You will have to excuse me because I do not know the technical talk of HVAC.

I have two zones (1 for the first floor, 1 for the basement.) Previously, the 2nd zone in the basement just had a electric fan connected through the copper and that was it for heat in the basement. I recently finished off my basement and replaced that fan and added several baseboards in the basement. After the system was connected, I added water in the system until I got the pressure to where it says on the meter. So the new 2nd zone is all connected, however, the zone does not seem to be running right.

When I turn on the zone, the furnace and the Zone 2 pump will kick on, however, the zone will not heat up. However, Zone 1 will heat up (even with the thermostat off, which causes the first floor to become very warm).

Do I have air in Zone 2? If so, how do I purge it? Wouldn't the water push the air out of the system? Do I need to add one of those ... corner things with a twist off cap in the zone 2 loop? Or should I have added a valve somewhere to let the air out?

Can anyone help?

You always need to figure a plan on how to bleed the system when you design it. Purge system's are very good for series loop baseboards. If you have piped it in a series paralle loop then you need to install bleeders at the high points of every baseboard.

Series loop is one pipe thru the system
Series Paralle is two pipe loop with take offs for every baseboard.
