vapor question

Timco

I have a customer with a vapor system, piped in a dead give-away method including the return trap. However, the return trap was long ago abandoned, who knows why. Should this trap be replaced or repaired, and reintroduced to the system? She does get a bouncing water line, but not really any no-heat situations due to low water. Second, this boiler has a standard pressuretrol. Never builds pressure, and seems to not be able to either. What would have originally run this boiler so it does not just fire forever during a heat call? Last, if the boiler is replaced, is the use of a vaporstat the only needed part to keep it vapor or should it just be run as a normal 2-pipe setup? All standard valves & traps, but typical return trap between 2 check valves.  Building does heat now, but I want to make it better, and learn while I am at it.

The Return Trap can be rebuilt

but I'd switch to the Vaporstat first. If they start shutting radiators down the pressure will build to the point at which it will overcome the "B" dimension, unless you have a Vaporstat or a working Return Trap.



Take some pics!

But until then, it is piped exactly as shown here. I am glad to scan the entire section discussing vapor if anyone is interested.

i think you can only post .JPG images or .PDF docs .. if you upload them somewhere else and post a link, i'm sure people will look at them.

I think it just scanned in too big. It was like 7000 x 4000 or something like that.
