FF there should be a fast fill on your bioler, it is hard to describe it has a square base maybe 3" x3" square and on the top is a lever that you can lift this will add water but you do not want your pressure to go up higher than 20 psi your PRV will pee off the overpressure, you need to make sure your zones are open when you add water one at a time however make sure the power is off you will smoke the zone valves by manually opening them with power on, this is also how your purge your system of air just add a hose and let the air and water run in one side out the other

thanks,
back to the basement.



it's ony one zone for the whole house.

[capesams]

one zone how come

[thefishingfreak]

whell i think it's one zone.
i can't shut any one room down unless i turn off the valves on the radiators.


here's what i found.
the pressure is down about 7 psi.
i found the piramid shaped valve to let water in.
i opened it bout ten/15 seconds, no psi change, ran upstairs three rads are filled w/ airlike never before ppppsshhhhhhh!!!!!!!!!!!!!. top floor two got nuthin, no air no water no nuthing.
do i let the water in the valve with the very top floor radiator bleeder open?
while i'm in the basement?
there is another bleeder near the burner, but litle air comes out.

Turn your heat up....bleed the air from the radiators from the closest to the boiler to the one furthest away! Make sure your water level is where it is supposed to be at the boiler....do you have one of those site glasses where you can read the water level?

Ditto what Larry said. I have radiators in my house and they make lots of noise when the water runs low.

[thefishingfreak]

tahhh dahhh!!!!
i fixed it!!!!
thanks guys!!
scratch one more from the honey-do list

there was tons of air in there!
lots of noise too.
i opened the water in--> valve till 20 psi, ran upstairs bled from lowest level to top. then back to the basement to raise the pressure again, then back upstairs for the very top floor. and voila' water now comes out.
back to the basement, raised the pressure back to 20 psi, and the whole house is toasty warm, and no more creeks either.

thanks again i knew i would find out here

should i keep it at 20 psi?
