MANDATORY REQUIREMENTS - (Continued)
R402.4.4 Rooms containing fuel -burning appliances. In Climate Zones3 through 8, where open combustion air duds 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 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 duds in the room in 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:
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 Florlda Building Code, Residential.
R402.4.6 Recessed lighting. Recessed luminaires installed in the building thermal envelope shall be sealed to limit air leakage
between conditioned and unconditioned spaces. All reoessed'luminaires shall be IC -rated and labeled as having.an air leakage rate not
more than 2.0 cfm (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.
SECTION R403 SYSTEMS
R403.1 Controls.
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
