Installation Instructions
MAXIMUM DUCT LENGTH: For satisfactory air movement,
the total duct length of a 3 1 ⁄
4
” x 10” rectangular should not
exceed 65 equivalent feet.
NOTE: Any home ventilation system, such as a ventilation
hood, may interrupt the proper flow of combustion air and
exhaust required by fireplaces, gas furnaces, gas water
heaters and other naturally vented systems. To minimize the
chance of interruption of such naturally vented systems, follow
the heating equipment manufacturer’s guidelines and safety
standards such as those published by NFPA and ASHRAE.
When applicable, install any makeup (replacement) air system
in accordance with local building code requirements. Visit
GEAppliances.com for available makeup air solutions.
