the services of qualified licensed professionals for the installation of hard-wired carbon monoxide detectors.
a.
In the event the side wall horizontally vented gas fueled equipment is installed in a crawl space or attic the
hard-wired carbon monoxide detector with alarm and battery back-up may be installed on the next adjacent floor.
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) day period, a battery-operated carbon monoxide detector with an alarm shall be installed.
2. APPROVED CARBON MONOXIDE DETECTORS:
Each carbon monoxide detector as required in

vented gas fueled heating appliance 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 gas fueled equipment shall not

2. Product Approved side wall horizontally vented gas fueled equipment installed in a room or structure separate
from the dwelling, building or structure used in whole or in part for residential purposes.
(c) MANUFACTURER REQUIREMENTS - GAS EQUIPMENT VENTING SYSTEM PROVIDED. When the manufacturer of
Product Approved side wall horizontally vented gas equipment provides a venting system design or venting system
components with the equipment, the instructions provided by the manufacturer for installation of the equipment

installation instructions; and
2. The "special venting systems" shall be Product Approved by the Board, and the instructions for that system shall
include a parts list and detailed installation instructions.
