I really like the shallow DoF! Not something I would be thinking about whilst inspecting.

I believe codes defer to the manufacturer's instructions. I don't think there will be anything to address this.

I removed the link from his post on Thurs. He just edited it today and put it back in.

Deleted & blocked.

It's not from any structural settlement.  They probably used a considerable amount of hydraulic repair mortar (expansive) to fill gaps below the windows. 

The manufacturer's instruction would have to show that the burner tray assembly was tested to a specific ANSI standard to allow it to be lit manually. 

Without that information, I would say that it needs a direct ignition device and a flame safeguard device.

I've also heard them called Atlas brick, but I think that's probably the name of a manufacturer.

Structural bricks. Usually installed with rebar through filled cores.

Slate back panel?

I've experimented with some thermally modified wood. I was wondering if it would ever make it as a building product.

I inspected it back when it was new construction.

Colosseum?

This doesn't address your point, but I've been in thousands of very old homes that have ceiling heights below 80". They were continually "habitated" for 2-3 centuries.

I owned a home that in the original 1690 section, some parts of the ceiling are at 78".

It also has 72.5"-73" door frame heights. Wasn't an issue till I wore my cowboy boots one day. Had a friend visit regularly that is 6'9".

Not sure if this is what you're looking for.

IRC - 21" clear space in front of tubs.

NKBA recommendation - 30" 

I wouldn't have seen it.

Lennox scroll compressor units have one dual capacitor for both compressor and fan. When the capacitor fails, nothing runs. 

Not worth fixin' - it's 19.5 years old. Most Lennox HPs from that era usually don't make it to 15.  

Bad start capacitor.

Thanks Nolan. Just recently saw a pair in a very old train depot.

Busy night in Britain.

I've come across it a few times.  Boiler room ceilings, stair and elevator towers. Tests showed it contains a very small percentage of fibers, surprisingly from wood.

And I thought this wasn't a place where guys would brag about bigger nuts.

If direct vent, many manufacturers have 18" as the minimum vertical clearance to vented soffits.  If mechanical draft, then 4'.

The collar is for a roof penetration, not a wall. The cap is probably for vertical termination only.

Not my photo - just the caption.

If the B-vent was closer than the vent stack...

Grew up exactly halfway between NYC & Philly.  Everyone had one. Bzzzz click bzzzz click bzzzz click - for like 10 minutes to go from North to south.
