Why gas logs gets documented this closely in Brentwood
For canyon-adjacent homes, the spark arrestor check gets logged yearly as a defensible-space precaution against ember travel, separate from the general sweep. Keeping that note on its own line makes the ember-safety history easy to pull up later. Visits here usually cover vented and ventless gas log options, btu sizing for room and firebox dimensions, and gas line connection with shut-off valve, and each item goes into the report so the scope matches the chimney's actual condition instead of a flat-rate guess.
