Bleeding a base board heating system

Jay_2

Let me describe my heating system.

I have a gas furnace, the heating system is a dual zone system one zone heats the 2nd floor, and the second heats the basement and first floor. On the second zone, I recently added about 10 feet of base board to one room, the room is about 3/4 of the way on the loop. The last part of the loop has little heat and the begining has a lot of heat. Someone told me that I had to bleed the system of air, but their doesnt seem to be any way to do this. Any suggestions?

air

When you added the baseboard you installed a vent ell or vent tee with a bleeder fitting. Right! open that bleeder fitting and let the air out. Make sure that the pressure returns to normal in the boiler after you bleed it. You may have to repeat the bleeding several times to get all the air out. Hey nothing to it, anybody can add baseboard! Having an attitude eruption. Local HO's doing sewer connections . Nothing to it just have to bury some pipe. Don't have to follow printed township spec. " The supervisor is my cousin ,drinkingbuddy ,etc. " and the local pipe purveyor is at it again street trade getting better pricing then the contractors. And people wonder why I have an attitude problem!! If Ho's do their own more power to them just follow the same spec, meet the same inspection criteria.I and other contractors are telling customers this is spec we have to follow and they are telling us that their buddy up the street is connected and approved and did no such thing . Makes a man want to start imbibing real early in the day

It is not

a furnace but a boiler. You should have either valves and draw-offs or bleed valves at the boiler. Turn your thermostat up, go to the boiler, hold your hand on the supply pipe (first one to get hot) and then hold the return pipe.
It should at least start to get warm. That's the line that is suppose to have a valve you can put a bucket under or even connect a hose to. Bleed some water out until it starts to get hot. It's a little more than this but you will get the hang of it quickly. Good luck. It is also possible that you added more baseboard than the loop can take and that is a whole different problem.

How much baseboard

do you have on the loop now, and what pipe diameter is it? You may have added more than the loop can take. Also what circulator is installed on this loop, and are you Pumping Away from the air separator/tank connection?
