Re: Oversized overtall chimney?
Guys,,, I really don't think the problem is a lack of combustion air… He's got a whacking great chimney there and is trying to find ways to reduce the amount of air going up it. I have seen a chimney that size develop enough draught to break a four foot a square piece of quarter inch plywood and try to such it up the chimney on a cold day with normal room temperature indoors.
If he really wants to reduce that draught he's going to have to drop a liner in there, sized to the appliance, and seal the space around the liner in the existing flue. That's going to cost, and other than the feel good of not having so much draught up the chimney it won't save enough on heating costs to make it worth the effort.
But folks, from the sound of it — don't worry about not having enough combustion air. That's not the problem.
Re: Help with Goodman GSXC16 Error code 04
that sounds like a bad neutral. it could cause the voltage of the control xfmr in the furnace to drop but the 240 v motors wouldn't cause it to drop. i suppose it could be one of the secondary lines was broken on the power system so it wasn't sharing load over the transformers

Re: GoldLine CM_50 solar control system
Unless there is reason to remove the collectors now, you might want to leave them and just remove the indoor parts. Leave the pipes and sensor wire to them cut with enough stub-out left so a future owner could reconnect (after pressure testing). Or just convince the owner to put it back in working order.
You might want also to take a hard look at the gas water heater's pressure relief valve as it appears to have a corrugated pipe attached. You want to make sure this terminates properly (i.e., not plugged, going uphill, or draining where it would not be noticed… and conforming to other code requirements.)
Re: Refurbished radiator making bird noises. Not vent?
Just asking — so often we hear of people running steam at a few pounds and wondering why it's noisy…
Re: Oversized overtall chimney?
That's because they won't alarm until 70 PPM is reached and exceeded for 3-4 hours!
Get non-UL approved Low Level CO Detectors that will alarm at 15 PPM

Re: Need some advice for a vintage Peerless radiator valve hookup
an lesson 2: that spud has to come out anyway, since it is actually half of the union connecting the radiator to the valve. The other half is/was on the valve, which I suspect is long gone. A new radiator valve will have the matching spud with it, and that gets threaded back into the radiator.
Re: Need some advice for a vintage Peerless radiator valve hookup
That brass spud can be carefully cut and caped out. You rarely have to remove them bushing unless you cut too deep in to the thread. As Mattmia said, this is plumbing 101 stuff. Mad Dog
Re: Need some advice for a vintage Peerless radiator valve hookup
You have to remove the spud and replace it with the spud that comes with the new valve. If your plumber doesn't know how to do that without breaking the radiator, find a better plumber.

Re: Oversized overtall chimney?
I have checked the specs on B-vent and not one tells us what temperature it has to be heated to vent. Chimneys are not mechanical devices. They are chases. You don't have to heat ductwork to get heat to flow. Can you oversize a steam pipe? look at some old chimneys on commercial buildings and their massive brick chimneys. Think they get heated before they vent. And why do chimneys vent in the summer when nothing operating?
Draft is a sign of combustion air. The higher the draft the more combustion air is available. The taller the chimney the higher the draft.
A neutral pressure point is also called a blast gas. Back in the 80's there was a product called a Thermizer that was a flue restrictor for residential and light commercial. They were very dangerous on drafthood equipment if you didn't understand venting and combustion air.
The chimney is too big was created by manufacters to make contractors look bad and then really pushed by liner companys.
Blast gate, barometric combined can do the trick.
And bring the firing rate back up some
