Masonry vent

[Darren]

When is a chimney not a chimney?

Yesterday, my inspection had a masonry fireplace chimney that was reworked so a gas log insert was installed and it had a new metal liner.

The masonry chimney was built too short for a fireplace, but now that it's re-lined, does the chimney rule apply or does the B vent rule apply?

Darren, since there's the potential of being unconverted back to a wood burning fireplace, I would say the chimney rule still apllies.

I don't think the chimney rule would apply unless the owners decide to go back to wood-burning. What if they tore the bricks off down to the roofline and went with a metal stack?

They will need to fix that flashing, so that would be a better option, IMO.

If it is in fact, lined with a B-vent, and has a listed B-vent termination, it no longer has any potential for burning solid fuel.
