individuals as defined in Section 553.993(5).or (7), Florida Statutes, or individuals licensed as set forth in Section 489.105(3)(f) (g) or (1) 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 any time 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 construction 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 infiltration 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 anii heat recovery ventilators shall be closed and sealed.
5. Heating and cooling systems, if installed at the time of the test, shall be turned off.
6. Supply and return registers, if installed at the time of the test, shall be fully open.
R402.4.2 Fireplaces. New wood-buming fireplaces shall have tight -fitting flue dampers or doors, and outdoor combustion air. Where
using tight -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.
R402.4.3 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 Us/m2), and swinging doors no more than 0.5 cfm per square foot (2.6 Us/m2), when tested according to NFRC 400 or
AAMA/ WDMA/CSA 101/1.S.21A440 by an accredited, independent laboratory and listed and labeled by the manufacturer.
Exception: Site -built windows, skylights and doors.

MANDATORY REQVIREMENTS - (Continued)
R402.4.4 Rooms containing fuel -burning 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 airopening shall be located outside the building therriial,envelope or
enclosed in a room, isolated from inside 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 ducts in the room Insulated in accordance with Section R403. The combustion air duct shall be Insulated where it
Passes through conditioned space tog minimum of R-8.
Exceptions:
1. Direct vent appliances with both intake, and exhaust pipes installed continuous to the outside.
2. 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 skull be IC -rated and labeled as having an air leakage rate not
more than 2:0 cfm (b.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
that, except during, defrost, prevent supplemental, heat operation when the heat pump compressor can meet the heating load.
❑ R403.3.2. Sealing (Mandatory) All ducts, air handlers, filter boxes and building cavities that form the primary air containment passageways
for air distribution systems shall be considered ducts or plenum chambers, shall be constructed and sealed in accordance with Section
C4032.9.2 of the Commercial Provisions of this code and shall be shown to meet duct tightness criteria below.
Duct tightness shall be verified by testing in accordance with ANSI/RESNET/ICC 380 by either individuals as defined in Section 553.993(5). or
(7), Florida Statutes, or individuals licensed as set forth In Section 489.105(3)(f), (g) or (I), Florida Statutes, to -be "substantially leak free" in
accordance with Section R403.3.3.
R403.3.2:1 Sealed air handler. Air handlers shall have a manufacturer's designation for an air leakage of no more than 2 percent
of the design airflow rate when tested in accordance with ASHRAE 193.
R403.3.3 Duct testing (Mandatory). Ducts shall be pressure tested to determine air leakage by one of the following methods:
1. Rough -in test: Total leakage shall be measured with a pressure differential of 0.1 inch w.g. (25 Pa) across the system,
