feet above finished grade in the area of the venting, includ-
ing but not limited to decks and porches, the following
requirements shall be satisfied:
1.
Installation of carbon monoxide detectors: at the time of
installation of the side wall horizontal vented gas fu-
eled equipment, the installing plumber or gasfitter shall
observe that a hard wired carbon monoxide detector with
an alarm and battery back-up is installed on the floor level
where the gas equipment is to be installed. In addition, the
installing plumber or gasfitter shall observe that a battery
operated or hard wired carbon monoxide detector with an
alarm is installed on each additional level of the dwelling,
building or structure served by the side wall horizontal
vented gas fueled equipment. It shall be the responsibility
of the property owner to secure the services of qualified
licensed professionals for the installation of hard wired
carbon monoxide detectors.
A.
In the event that the side wall horizontally vented gas
fueled equipment is installed in a crawl space or an attic,
the hard wired carbon monoxide detector with alarm and
battery back-up may be installed on the next adjacent
floor level.
B.
In the event that the requirements of this subdivision can
not 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 car-
bon monoxide detector with an alarm shall be installed.
2.
Approved carbon monoxide detectors: each carbon mon-
oxide detector as required in accordance with the above
provisions shall comply with nfpa 720 and be ansi/ul 2034
listed and ias certified.
3.
Signage: a metal or plastic identification plate shall be
permanently mounted to the exterior of the building at a
minimum height of eight (8) feet above grade directly in
line with the exhaust vent terminal for the horizontally
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 ap-

B. Boiler Sizing
Check to be sure you have selected the boiler with the proper
capacity before starting the installation. The I=B=R Rating of
the boiler selected should be greater than or equal to the cal-
culated peak heating load (heat loss) for the building or area(s)
served by the boiler and associated hot water heating systems.
See the table "BOILER RATINGS AND CAPACITIES".
Heat loss calculations should be based on approved industry
methods.
C. Considerations For Boiler Location
Before selecting a location for the boiler, the following should
be considered. Each boiler considered.

tions for all product approved side wall horizontally vent-
ed gas fueled equipment, all venting instructions, all parts
lists for venting instructions, and/or all venting design
instructions shall remain with the appliance or equipment
at the completion of the installation.
