Water heater vent

[randynavarro]

Does this water heater vent enter the stack above the furnace or below it?

It's not a trick question or a test.

OK I'll bite. Over, but why ask? Looks pretty typical around here. I was under the impression that as long as a "y" is used (not a "t") to connect the two flues together is was ok. Not ideal, but ok.

Not asking for bites or trying to lure anybody. I was pretty clear; it's not a trick question.

The furnace is entering the leg of the Y. Looking at that configuration, the furnace flue gas is entering the main stack after or above the water heater, no?

Typically, the furnace would be connected to the inlet of the Y and the water heater connected to the leg.

Maybe I'm over-thinking. . .the report is off with not a mention. From a practical standpoint, I don't think anything could happen.

I've been wrong before. . . .

To my understanding the furnace should enter below the water heater.

The bigger flue should be on the bottom (1st in) and the smaller flue connects above it.

If the flues are the same size the larger BTU unit connects to the bottom.

I may not be seeing the photos as you seen it on site.

They're entering at exactly the same spot. The water heater gases are moving in a straight line and the furnace gases alter course by 45 degrees once they enter the wye.

Typically, the furnace would be connected to the inlet of the Y and the water heater connected to the leg.

I don't see an issue. Neither is really entering above the other, they're coming together at the wye. If someone wanted to press the issue, yes, the lower BTU appliance should enter the vent above the higher BTU appliance. In this case, I couldn't come up with a reason why it would make a difference, though.

we're required to have an access/inspection point on b-vented chimneys when we do an install or local utility co will tag the job when they inspect the install.Ive never seen a furnace piped/vented that way before

Well, that explains your comments in another thread where you'd photographed one of those vents.

I almost never see exhaust vents with cleanouts/inspection ports like that done around here. The ones that I have seen - the bottom was all rusted out or dripping with condensate.

ONE TEAM - ONE FIGHT!!!
