Do you have a codified link?

Going off thread: Hope you had a good time, or have a good time with your companion seeing either you got in late, or woke up early.
I suspect the before as opposed to the later.
Happy to see you are not feeling single while seeing double

Is that a Type B gas vent and an approved Type B gas vent cap and listed for wall use?

That appears to be a gas fireplace direct vent termination made by Heat&Glo. It should NOT be mortared directly into a masonry wall but extend through a sleeve that gets caulked. The termination must extend at least 7" from the face of the wall for proper operation. If this is what I suspect it is, this vent carries a 1" clearance to combustibles off the sides and bottom/ 3" off the top. The manual will show clearances to sidewalls and nearby obstructions but no way should that condenser be so close to it. This can result in improper airflow in and out of this vent.

FYI, B-vent can not sidewall terminate using atmospheric venting. It must terminate above the roofline UNLESS it has an approved power exhauster on the outside wall with a pressure proving switch linked to the burner control. See the sidewall exhauster's instructions for clearances to it.

What is the appliance attached to this vent? That's ALWAYS the most important question and should be provided on ALL venting queries.

I should have realized that/this.
Pardon me colleagues.

Time appears to handicap me lately, Bob.
I typically go to the manufacturer.

CD, 6" clearance from the compressor/coils.

Thank you.
Kindest regards.
