I noticed that the installers of my gas water heater and gas furnace did not glue the fittings outside the house.
All the connections are glued inside the basement. However, outside there were 3 stubs sticking out of the wall all about 3".... (one for furnace exhaust, furnace intake and w/h exhaust). The installer mearly connected a coupling on each one and built the appropriate termination ends from there that consist of a length of pipe and elbow for each one.
However, when doing some yardwork I realized I could pull off the terminations from the coupling, leaving just the stubs sticking out the wall.
Is this standard?
Is this a carbon monoxide hazard?
Should it be corrected?

Unless the vents are terminating under a window or door, it isn't an issue. The only concern would be if the vent was the exhaust, and it was terminating under a window or door. The area of more concern would be the penetration of the pipe through the exterior. Is it caulked shut so that exhaust gasses and pests can't enter?

the gas inspector passed this??
call him/her to report such shoddy workmanship. the installer needs to be reported.

Is there a reasoning why that might be accepted though? Perhaps for cleaning of ice or something?
As far as CO poisoning though, do you think that's a risk?
FWIW
the water heater exausts connects with coupling and then extends out with about 6" pipe and a 45' ...
The furnace exhaust connects with coupling and then extends out with about 12" pipe and 45
The furnace intake just has a 90 on it.
All of the terminations are done to specs in the installation manuals. And every joint is glued on the interior of the home.

if you want to make it them removable, put 3 stainless pan head screws into each joint. also make sure you have the insect/critter screens installed in each pipe.
as for any leakage causing you harm, not outside it won't..
it is also a good idea to have a hard wired CO detector near the heater.

"if you want to make it them removable, put 3 stainless pan head screws into each joint."
Right, but they will still leak that was my concern.

well if you are that concerned, use sheilded 4 band stainless clamps to join the piping.
you will have to use street fittings (one male end)

that's an idea but those aren't probably listed for condensate.
Maybe I am being paranoid? Since the unglued couplings are a few inches from the open pipe! So its no more a CO hazard outdoors...

in any case, they should be secured. i would just use stainless pan head screws.

why not just glue the pipes even if they don't need to be and relax

I would use screws as Packy suggested, just in case they needed to be accessed for some reason.
