accordance with ANSI/RESNET/ICC 380 and reported at a pressure of 0..2 inch w.g. (50 pascals). Testing shall be conducted by either
individuals as defined in Section 553.993(5) or (7), Florida Statutes, or individuals licensed as set forth in Section 499.105(3)(f), (9) or (i) or
an approved third party. A written report of the results of the test shall be signed by the party conducting the test and provided to the code
official. Testing shall be performed at anytime after creation of all penetrations of the building thermal envelope.
Exception: Testing is not required for additions; -alterations, renovations, or repairs, of the building thermal envelope of existing
buildings In which the new constriction is less than 85 percent of the building thermal envelope.
During testing:
1. Exterior windows and doors, fireplace and stove doors shall be closed, but.not sealed, beyond the intended weatherstripping or
other infiltrat!on control measures.
2..Dampers. including exhaust, Intake, makeup air, backdraft and flue dampers shall be closed, but not sealed beyond intended
Infiltration control measures.
3. Interior doors, if installed at the time of the test,_ shall be open.
4. Exterior doors for continuous ventilation systems and heal recovery ventilators shall be closed and sealed.

❑ R402A.2 Fireplaces. New wood -burning fireplaces shall have tight -fitting flue dampers or doors, and outdoor combustion air. Where
using light -fitting doors on factory-built,fireplaces listed and labeled In accordance with UL 127, the doors shall be tested and listed for the
fireplace. Where using tight -fitting doors on masonry fireplaces, the doors shall be listed and labeled in accordance with UL 907.
❑ R402A.3 Fenestration air leakage. Windows, skylights and sliding glass doors shall have an air infiltration rate of no more than 0.3 cfm
per square foot (1.5 UsIM2); and swinging doors no more than 0.5 cfm per square foot (2.6 lds/m2), when tested according to NFRC 400 or
AAMA/ WDMA/CSA 101/I.S.2/A440 by an accredited, independent laboratory and listed and labeled by the manufacturer.
Exception: Slte-built windows, skylights and doors.

MANDATORY REQUIREMENTS - (Continued)
❑ R402.4.4 Rooms containing fuel-buming appliances. In Climate Zones 3 through 8, where open combustion air ducts provide combustion air to
open combustion fuel burning appliances, the appliances and combustion air opening shall be located outside the building thermal envelope. or
enclosed in a room, isolated from in the thermal envelope. Such rooms shall be sealed and insulated in accordance with the envelope requirements
of Table R402.1.2, where the walls, floors and ceilings shall meet not less than the basement wall R-value requirement. The door Into the. room shall be
` fully gasketed and any water lines and duds in the room insulated in accordance with Section R403. The combustion air duct shall be insulated where it
passes through conditioned space to a minimum of R-8.
Exceptions:
Direct vent appliances with both intake and exhaust pipes installed continuous to the outside.
Fireplaces and stoves complying with Section R402.4.2 and Section R1006 of the Florida Building Code, Residential.
❑ R402.4.5 Recessed lighting. Recessed luminaires installed In the building thermal envelope shall be sealed to limit air leakage .
between conditioned and unconditioned spaces. All recessed luminaires shall be IC -rated and labeled as having an air leakage rate not
more than 2.0 clim (0.944 Us) when tested in accordance with ASTM E283 at a 1.57 psf (75 Pa) pressure differential. All recessed
luminaires shall be sealed with a gasket or caulk between the housing and the interior wall or ceiling covering.
R403.1 Controls.
SECTION R403 SYSTEMS
❑ R403.1.1 Thermostat provision (Mandatory). At least one thermostat shall be provided for each separate heating and cooling system.
❑ R403.1.3 Heat pump supplementary heat (Mandatory). Heat pumps having supplementary electric -resistance heat shall have controls
