I have gas direct vent unit, vents out side wall for my forced hot air/ac, and have the following issue.
Filling out the chimeny certification I need to proceed, and they are asking "Existing Vent/Chimney:"
The old chimney no longer in use is a simple masonry lined chimney, is this what they are asking about, or what the new units are? In the event it is about the new units, does anyone know what they are? Pretty sure it is Power vent/exhauster or other. Thanks.
I have to have the plumber sign off on the line
"Direct Vent appliance: No certification required"
