What to do if a downdraft stove top is venting to the exterior under the slab in a
PVC pipe.

Answer 1

To resolve a downdraft stove top venting issue, check for leaks or loose fittings, replace the pipe if it is too small or blocked, and repair or replace any damaged or deteriorated PVC pipe.

Step-by-step explanation:

If a downdraft stove top is venting to the exterior under the slab in a PVC pipe, there are a few steps you can take to resolve the issue:

1. Ensure that the PVC pipe is properly connected to the stove top. Check for any leaks or loose fittings that may be causing the venting problem.
2. If the PVC pipe is too small or has become blocked, it may be necessary to replace it with a larger diameter pipe. This will allow for better airflow and prevent the build-up of gases.
3. If the PVC pipe has been damaged or deteriorated, it should be repaired or replaced. A damaged pipe can cause the vented gases to leak into the indoor air, which can be hazardous.

By addressing these issues, you can ensure that the downdraft stove top is correctly venting to the exterior and prevent any potential health hazards.
