Well, you really don't need to support that elbow at the unit. Now if it was further up the flue pipe then it would need support with some plumbers strapping.

I've looked closely and see nothing "attaching it", hence, it does not have proper "support" (i.e., it could slip off, thereby falling down and no longer being connected).

Guess it depends on how *you* define "support". (That is, if it is not "attached".)

Dan,

Hope this isn't a dumb question.

Is that equipment sitting on top of Styrofoam?

The B-vent appears to be attached to a piece of single walled pipe with one screw and that is just stuck on the appliance collar without screws. There should be 3 screws per joint. What is to keep the vent from pulling off the appliance collar? The weight of the B-vent pushing down on that elbow may be enough to blow the elbow apart one of these days. The vent mfr. specifies the installation, which includes support. If there is a listed support device per specs. then add screws and be done. Otherwise, get the listed parts, install to the listing and you're done.

Guys, there really isn't any need for all this guess work I see here all the time. When you have listed systems such as appliances and venting, record the mfr., model, and any serial or other identifying numbers. When you get back to your office, research that system and you'll get your answers. The code requires you install a listed system in accordance with the mfrs. listed instructions. What is so hard about that? Don't try to add ambiguity to such as simple issue. Either it meets the mfr.s instructions or it doesn't.

I'm off to Pittsburgh for the ASHI Conference there. Teaching in the morning.
In the coming weeks, I won't be able to post here as much as I did this summer since my Silly Season is arriving.

Warmest regards,
