* Gas input ratings are certified for elevations to 2000 ft. For elevations above 2000 ft, reduce ratings 4% for each 1000 ft above sea level. In Can-
ada, derate the unit 10% for elevations 2000 to 4500 ft above sea level.
† Capacity in accordance with U.S. Government DOE test procedures.
‡ Air delivery above 1800 CFM requires that both sides, or a combination of 1 side and bottom, or bottom only of the furnace be used for return air.
Where 2 sets of data are listed, the first set is for bottom only return-air supply. The second set is for both sides, or 1 side and bottom return-air
supply. A filter is required for each return-air supply.
ICS—Isolated Combustion System

Clearance to combustibles

This unit complies with CAN/CGA 2.3 M86, CAN/CSA C22.2 No. 0-M91, CSA C22.2
No.3-1988 standards.
This appliance is equipped only for altitudes 0 - 2,000 ft (0-610 m) for use with natural
gas and propane. A conversion kit, supplied by the manufacturer, shall be used to
convert to the alternate fuel or elevation.
This direct-vent, forced-air furnace is for indoor installation in a building constructed on
site. For installation in alcove or closet at minimum clearances from combustible material
as shown below, minimum front clearance for service is 30 inches (762 mm).
This furnace is for use with schedule-40 PVC, PVC-DWV, or ABS-DWV pipe, and must
not be vented in common with other gas-fired appliances. Construction through which
vent/air intake pipes may be installed is maximum 24 inches (600 mm), minimum 3/4 inches
(19 mm) thickness (including roofing materials).
Special venting system required. In Canada use certified venting system specified by
furnace manufacturer. See Installation Instructions provided with furnace. Flue gas
temperature 131°F (55°C) vent pressure positive.
++ For installation on combustible floors only when installed on special base No.
KGASB0201ALL.
Clearance shown is for air inlet and air outlet end.
*
Horizontal position: Line contact is permissible only between lines formed by
intersections of top and two sides of furnace jacket, and building joists, studs, or framing.
+ 120,000 BTU Input Furnaces require 1 inch bottom clearance to combustible materials.
