One opening MUST be within 12" (300mm) of the floor and
the second opening within 12" (300mm) of the ceiling.
Size openings and ducts per Table 1.
Horizontal duct openings require 1 square inch(25sq, mm) of
free area per 2,000 BTUH of combined input for all gas ap-
pliances in area (see Table 1).
Vertical duct openings or openings directly to outside require
1 square inch(6.5mm 3) of free area per 4,000 BTUH for com-
bined input of all gas appliances in area (see Table 1).
(16 cm) from the front of the appliance. The opening shall directly
communicate with the outdoors or shall communicate through a
vertical or horizontal duct to the outdoors or spaces (crawl or attic)
that freely communicate with the outdoors, and shall have a mini-
mum free area of:
• 1sq. inper 3000 Btu per hr (7cm2 per kW) ofthe total inputrating
of all equipment located in the enclosure, and
• Not less than the sum of the areas of all vent connectors in the
confined space.

Poison carbon monoxide gas hazard.
Most homes will require additional air.
An unconfined space or homes with tight
construction may not have adequate air infiltra-
tion for proper combustion and ventilation of
flue gases.
Failure to supply additional air by means of ven-
tilation grilles or ducts could result in personal
injury and/or death.
An unconfined space is defined as an area having a minimum vol-
ume of 50 cubic feet(1.4m 3)per 1,000 Btuh total input rating for all
gas appliances in area.
Adjoining rooms can be considered part of an unconfined area if
there are no doors between rooms.
One permanent opening, commencing within 12" (30 cm) of the
top of the enclosure, shall be permitted where the equipment has
clearances of at least 1" (2.5 cm) from the sides and back and 6"
/SJ
An attic or crawl space may be considered an unconfined space
provided there are adequate ventilation openings directly to out-
doors. Openings MUST remain open and NOT have any means
