INSTALLATION

This forced air furnace is equipped for use with natural gas at altitudes 0 - 10,000 ft (0 - 3,050m), except 140 size furnaces are only approved for altitudes 0 - 7,000 ft. (0 - 2,135m).

An accessory kit, supplied by the manufacturer, shall be used to convert to propane gas use or may be required for some natural gas applications.

This furnace is for indoor installation in a building constructed on site. This furnace may be installed in a manufactured (mobile) home when stated on rating plate and using factory authorized kit.

This furnace may be installed on combustible flooring in alcove or closet at Minimum Inches Clearance To Combustible Construction as described below.

This furnace requires a special venting system. Refer to the installation instructions for parts list and method of installation. This furnace is for use with schedule-40 PVC, PVC-DWV, CPVC, 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).

	LEVEL (0")TO	MIN 1/4" TO 1/2" MAX
For upflow and downflow applications, furnace must be installed level, or pitched within 1/2" of level. For a	1/2" MAX
horizontal application, the furnace must be pitched minimum 1/4" to maximum of 1/2" forward for proper		FRONT
drainage. See Installation Manual for IMPORTANT unit support details on horizontal applications.	UPFLOW OR	FRONT
	DOWNFLOW	HORIZONTAL

MINIMUM INCHES CLEARANCE TO COMBUSTIBLE CONSTRUCTION

ALL POSITIONS:

*	Minimum front clearance for service 30 inches (762mm).
† †	140 size furnaces require 1 inch back clearance to combustible materials.

DOWNFLOW POSITIONS:

†For installation on combustible floors only when installed on special base No. KGASB0201ALL, Coil Assembly, Part No. CD5 or CK5, or Coil Casing, Part No. KCAKC.

HORIZONTAL POSITIONS:

Line contact is permissible only between lines formed by intersections of top and two sides of furnace jacket, and building joists, studs, or framing.

§Clearance shown is for air inlet and air outlet ends.

Ø120 and 140 size furnaces require 1 inch bottom clearance to combustible materials.

This furnace is approved for UPFLOW, DOWNFLOW and HORIZONTAL installations.
