What to do with this?

I have been doing some odds and ends at a friends house and he asked me to put a rain cap on his flue and some how seal up the chimney so critters can't get in. The vent is only for a gas water heater. Got the cap on (not in the picture) but I am unsure how to cover up the hole. Put metal mesh screen over it? Do I seal it up with mortar or just leave it open?

What did they do, run the water heater flue through the chimney? In other words, do I see a dual purpose setup, the chimney for the heat & the flue for the water heater? Can you post a pic of the cap that you used?

whether its right or wrong I don't know. But I would screen the chimney and put a vent cap on the stack.

The pipe, I think, is a chimney liner. They used to have an old gravity furnace. It is only for the water heater as they had a new furnace installed that vents through the sidewall with PVC. This is the vent cap I used: https://www.menards.com/main/heating...166-c-9462.htm Pipe was bigger then 5" but smaller then 6" so I installed a 6" cap.

It sounds like a 5.5" pipe get a liner top plate for it and that will cover the old flue + hold liner in place and reinstall your cap. I would have got a stainless steel cap though considering the liner is and then you don't have to worry about galvanic corrosion.

Not sure if this is what is mentioned, but a carefully measured and fitted cap for the entire top of the chimney, then a rain cap for the pipe would be my choice. Gotta cover all the brickwork with a drip lip around the perimeter. This one lacks the drip edge, but was close to what I was thinking.

That looks like a good option. Thanks!

Finally got back to this. Found a place that would let me use a shear and break and bend up some galvanized tin out of some scrap. Had to fish out a smelly dead squirrel with a piece of conduit (ick!) but I think it turned out pretty good. I was also able to center the pipe.

Berry Good!! The only thing I would have done would have been to put a kick or rain drip around the perimeter at the bottom. Your decorative brick are sloped, so you shouldn't have any problems.
