Ch 240 navien - add baseboard to existing
1 Attachment(s)
Livingroooms cold all esle good. Just want add another 6 feet baseboard. Curentlly theres inly one 8 foot and its a good size living room. 16x14. Have all the tools to add this additional basebard . My question is what do I have to do in terms of draining water from the sytem and refilling water, etc. Just know how to add the baseboard thats it.

Also there is radiant flooring in the basement slab that is not a seperate zone that can be tempature controlled. The flooring is on its own loop with shutoffs on the in and out. Is it not ok to turn this loop shutoffs on and off every time it heats up to much or gets to cold. Eventually plan to have this put on own zone but for dont have the cash

Thanks in advance and happy new year!

Best to just set the valve on the return to a choked down position that keeps the basement tempered.

Post pis of the boiler. hard to tell someone how to drain a system and refill and purge without seeing whats there.

Thanks for the reply beenthere! Just posted a pic of the sytem to figure out how to drain and all that. As for the basement heating im guessing you mean just turn the return off a bit? The loops in the manifold are maked in and out. Which would be the return?

Thanks so much, really appreciate the help

Need a bit close pic of the valves to tell you about purging.

If out is the return(the water coming back from the loop/slab) choke it down.

First pic of the second set. The valve to drain the loops is just above the ball valve with the handle pointing down. This will also serve as the purge set up to get air out after you install the additional baseboard. Because of that check valve at the circ, you won't et all the water out of the baseboard. So use a pan to catch what is left at the baseboard when you cut it open.

1. Power down boiler Drain loops by. Opening menrioned valve 5 inches above ball valve in 1st pic and let water draun out into buckets

2. Cut in rafiator where im.going to have and have pan ready to catch water

3. Add my radiator

4. What would this step be? Does the system need to be refilled or anything? Or just turn power to boiler back on?

Refill and purge system.

Connect a hose to the valve whee you drained the system. Turn the valve below if off. Open fill valve and add water at a fast rate and continue to do so until air stops coming out with the water.

1."Turn the valve below if off.*" do you mean if off turn on?
2. Can you tell me if the "fill valve" is just the water supply to the unit?
3. "Until air stops coming out with water" am I checking for this at the end of hose

Thanks a million attemotinf this tommorow!

the valve is on/open currently. it needs to be open in order for the system to work. Needs to be closed to purge the system. From the pics, I can't tell which/whee your fill valve is.

Mikee_s_1975 01-03-2013 07:56 PM

Thanks so much! Is the fill valve the same or different feom.the valve that is the water supply into the system?
