Bye Bye Burnham

[wink]

Biggest thing I see wrong is
A-(osv)wrong place
B-(no spirovent)

good job(buen trabajo carlos)

Ummm, no, if you use zone valves you don`t need to install flow checks,all your doing is moving the location of the pump.

My understanding and experiance is that if you install a Circulator on the supply side and zone valves on the return side you will need flow controls on the supply side to prevent creep heat in the zones that are not open.

We just repiped a home that had that installed by the home owner. Now he has no mo creep heat.

I like spirovents also, but with the Peerless they already have a tapping on the boiler for air venting too much redundancy. We have not had any problems

OSV in the wrong place? That is just the shut off near the boiler. There is another 2 behind the well trol.

I prefer a valve directly before and after the circ.

At 2 in the morning I'm a little lazy, so I like it to be easy changing circs, or cartridges.

Nice install though.

I'd open that 1 1/4" ball valve on the return

to heck with the shutoff's use webstone flange valves! http://www.webstonevalves.com/isolator.html

Now those are nice!

Ant time you get to pull a Burnham its a plus, the job looks real good.
I tend to go the other way though, with pumping away, and any thing with more than 1 zone I upgrade the circulator.

pumping away is from the point of no pressure change, not necessarily meaning away from the boiler. The pressure is lowered on the return side of the circulator every time it starts the way this system is piped. This causes the auto fill to react as if the pressure is low. In time it is possible the pressure relief valve will start to leak. To resolve this move the Xtrol to the inlet side of the circulator so it is pumping away from it. The Xtrol or bladder tank is the point of no pressure change

hi there,
Please can somebody tell me why do we in Europe fit the expansiontank in the inletside and you [North America ]put it in the outletside?
If you put it in the inletside it gets less hot and will last longer, this is maybe not so good for the company, but more relayable.
Please share youre thoughts whit me..

Sorry 'bout the yellin......

I will order the book, but in the meantime you check this out: http://www.diydata.com/planning/cent...ing/boiler.htm

Remember the pump is forcing the water trough the system and building up [extra] pressure, so hotter water is forced into the vessel damaging the membrane, you will find probebly more black residue in the water.
The xp vessel shout be mounted close near the inlet of the pump in order to keep positive pressure in the system.
At least that is what teachers told us.
This was a long time ago,i agry, but still why the differends???

kEEP UP THE GOOD WORK.

Factory chimney must be installed to the listed instructions. Not a clear shot but I don't see a listed ceiling support. Do NOT pack kaowool or anything into stated clearances! This is an extreme fire hazard. As a mfrs. rep. who investigates fires, trust me.
There should be an 18" clearance to combustibles. That includes the ceiling, PVC pipe, wiring, etc.
There is no cleanout. In ceiling applications, you'll need a tee and connect to the snout.
The barometric damper should be located close to the appliance collar.

If you check the firing rate and look it up in NFPA 31, you'll probably see where this vent is oversized.
