up may be installed on the next adjacent floor level.
b. In the event that the requirements of this subdivision cannot
be met at the time of completion of installation, the owner
shall have a period of thirty (30) days to comply with the above
requirements; provided, however, that during said thirty (30)

or equipment.
The sign shall read, in print size no less than one-half (1/2) inch in
size, "GAS VENT DIRECTLY BELOW. KEEP CLEAR OF ALL OBSTRUCTIONS".
4. INSPECTION
The state or local gas inspector of the side wall horizontally vented
