This furnace is shipped in one package, completely assembled
and wired. The indoor thermostat and accessories are shipped in
a separate carton when ordered.

damage. Examine the furnace inside the carton if the carton
is damaged.
If damage is found, it should be noted on the carrier’s freight bill.
Damage claims should be filed with the carrier immediately.
Claims of shortages should be filed with the seller within 5 days.
NOTE: If any damages are discovered and reported to the carrier,
do not install the furnace, because your claim may be denied.
Plan Vent System
Confined Space Installation—Nondirect Venting Air from
Inside
If the furnace is installed in a confined space within the building
and combustion air is taken from a heated space, the
combustion air and ventilating air must enter and leave the space
through two permanent openings of equal area. One opening
shall be located within 12" (30.5 cm) of the ceiling and the other
within 12" (30.5 cm) of the floor.
NOTE: Each opening must have a free area of at least 1 sq. in.
(6.4 cm
2
) per 1,000 Btu/h of total input rating of all equipment in
the enclosure, and not less than 100 sq. in. (645 cm
2
) each.
Equipment in Confined Space—All Air from Inside
Confined Space Installation—Nondirect Venting Air from
Outside
If air from outside is brought in for combustion, the confined
space shall be provided with two permanent openings. One
opening shall be within 12" (30.5 cm) of the ceiling and one
opening within 12" (30.5 cm) of the floor. Several methods can be
used to bring the outside air in through these openings. The
openings must open directly or by ducts to the outdoors, through
spaces (crawl space or attic) that freely open to the outdoors, or
indirectly through vertical ducts.
NOTE: If any of these methods are used, the inlet and outlet air
openings must each have a free area of 1 sq. in. (6.4 cm
2
) per
4,000 Btu/h of the total input rating of all equipment within the
enclosure.
