Default Firewall penetration

Garage has two metal combustion air intakes for a prefab fireplace penetrating the garage firewall separation. Would you call this out? It could pull exhaust fumes from the garage into the living space.....yet it would be in the fireplace and vented out the chimney.....

That doesn't sound good. What will happen if the combustion air is full of gas fumes?

Combustion air shouldn't be taken from the garage.

Default Re: Firewall penetration

There is no restriction against using the garage as a source for combustion air (common place for water heaters), but the penetrations to the firewall are prohibited.
