    I need to eliminate about a 12' section of hot water baseboard heater. The section is on the first floor and the furnace is in the basement. There is no second floor. So I need to reconnect the loop after the section I want gone is removed, this part I understand. I also understand the furnace needs to be shut off of electricity and I'm assuming I need to shut off the main water valve feeding the house. There is a spicket at the bottom of the furnace and I'm assuming that is where I'll need to drain it from? So once it's drained I can cut out and then reconnect the loop with some new pipe. So I'll obviously need to refill the system now but the part I'm not sure about is purging the air from the system. On top of my hot water heater there is a fitting that says something like "air release". Is that where I can release air from the system? Or should there be another area that needs to have the air purged from? I haven't inspected behind all the access covers yet on the baseboard heaters themselves to see if there are any purge fittings or not. All the covers are painted shut. I'm willing to take pictures of anything and post them on here if it will help. Thank you.

    It's hard to see in the pic bit that nipple in the middle of the hot water heater says "air vent"

    You need to purge each of the zones this is no simple task my recommendation is to get someone to do it for you

    Well I've considered paying someone but I'm fairly confident I can do it if I can get some proper directions.

    By zones do you mean the air purge fittings on the baseboard heaters themselves?

    I should be able to direct you how to purge the system. I need a picture of the side of the boiler were the circulator is. From what I can see there should be three. What your calling air vent is on your domestic hot water.

    Here's the side pic of the furnace, I believe these are the circulators. Not sure if it's needed but here's another pic of the top of the hot water heater.

    Forget the water heater it has nothing to do with the heating system. There should be three boiler drains above the calculator's. Do you see them?

    I'm not sure I understand. Are you asking to see pics of all the pipes in the house?

    I can take a pic of it but does it matter? Has nothing to do with the heating system right?

    Looks like you have an indirect water heater which is connected to your boiler that air vent at the top has nothing to do with anything that you want to do. the reason I ask for a picture was that I was assuming it was an indirect water heater I could be wrong

    I think you're right, it is an indirect water heater.

    I just need to know how to properly drain the pipe so I can cut out and eliminate a section of baseboard and then add a pipe to complete the loop and then properly fill with water and purge the air out.

    No need to drain the entire system to make your changes. Trace the piping back to the boiler to see which feed and return connect to the zone your working on. Then turn the valve below the circulator off along with the one that feeds that zone. The feeds are on the top of the boiler with the red flow valves. After you have them off drain the water from that zone using the drain valve above circulator for that zone. To purge the air from the zone after your done connect a hose to the same drain that you used to drain the zone. Open the valve you turned off on the feed. (don't turn the return on yet) Let the hose run it will force all the air out of the zone. Once the water coming from the hose looks free of air turn the drain off and open the valve on the return.
