WIRE ? it ? you mean for the built in Christmas lites ? :lol: If you are referring to the roof support,see above.
No I am referring to bracing the outside portion of the chimney so it does not get blown over. A set of two tube braces or four guy wires should be enough to prevent the stack from moving
You have a lot of "sail" area sticking above the roof of the box.

Lu47Dan,i guess
'roof support " is the wrong wording, Ventiss calls it a telescoping roof brace,that is what we need the ss screws for.

Okay, I have seen them blown over with the high winds we get here.

Funny you mention that.. His commentary often has me looking at the screen cross eyed too. But then I found out he is a RUSH fan. That of course, brings him back to the top of the pile.. :D

Lightning,since I don't like Rush & that type of music do I fall to the bottom of the pile ? :) Doyle Lawson & Quicksilver with bluegrass gospel is my favorite,& I usually have them singing/playing while on the forum. We have one cat that talks very loudly when I am on here & don't have music on,click on the singing/music & she will get all dreamy eyed (she listens very closely to it). Today we got the 2 manifolds for the supply & return & I decided to get the circulators ready,well, hooked electric to them & 2 of them are very noisy. Guess I will be ordering new ones, of the current ones that I looked at,1 has the IFC ,the other 2 do not. I need some good advise on the IFC issue,pro/con,looks like without the IFC the pump can gain up to 6 gal per minute more ? or am I reading it wrong ? I would also like to get the rotated flange but it seems that requires the IFC. I want to get these pumps ordered soon just not sure on the benefit/drawback with/without the IFC. Using the manifolds should prevent ghost flows if I have been reading correctly,so is the IFC still necessary for that issue. Thanks in advance for any/all advice,opinions & info that will help with this decision.

Pumps are lubricated by the rotor being wet...running dry is not good for them.

IFC's are little plastic device push into flange orifice, they go in or out w/ little difficulty...order them with and you still have time to change your mind. ;)

So you are saying that the IFC is actually detrimental to the pump ? If no IFC will we then have ghost flow/gravity feed or will most of that issue be eliminated with using the manifolds ? they have an equal 6 " spacing between the ports.

You had commented that you had 2 noisey pumps when test running them while they are still dry...they need to be wet and then they will be quiet...system water is the lubricant.

IFC are good. And are not a permanet thing...you can pop them out or in to suit your choice.

The closer to the boiler the better the Flow-Chek works. Keeps the heat in the boiler where
belongs.
A pump running 24/7 needs no check.
When/where both the supply and return turn downward quickly out of boiler no check is needed.

You should wash that out too

McGiever, earlier you posted that I should be installing a wye strainer b4 the manifold,is there any concern that dirt could plug the strainer & stop the entire flow of water thru the boiler ?Or does dirt in the screen not affect the water flow thru/past the screen ? If dirt clogs a circulator,only that circuit would stop flowing.I am trying to put another order together,hopefully the last one & want to get all the remaining missing pieces.

Sting, we did vac out the crud dust & looked in with flash lite & felt in around the corners with a finger ,it appears that the shop vac did a pretty good job of removing the dust.

Dirt or "mud" can be very abrasive and will / could / may even worry the pump impeller to bits

if its bad enough and left in play long enough.... :o

If you wash out the mud legs or in this case the bottom of the used boiler and you have flushed your zones - I would venture - your good to go

but

It Depends!

No concern of plugging.
Wye Strainer gets a drain valve where you would open the valve and purge what has collected inside the strainer.
Strainer inside is a little basket and can hold a bit of debris, just periodically open the valve and find out what has collected.
Without strainer your water lubed circ. pumps would be running w/ sand like abrasives in it...sand makes a poor lubricant.

Bigger particles may remain in bottom or lowest part of the vessel and your only chance of removal is cracking the low point boiler drain seasonally early before things would get stirred up or after has been let sit a while. But since the particles are trapped they pose less problem than the smaller circulated ones.
