furnace installed on a combustible floor, consult the applicable code and
authorities having jurisdiction on this application. The floor must support
the weight.
VENT
The KLC can be vented vertically through the roof or horizontally through
the wall. The appropriate venting material must be rated to a minimum
operating temperature of 65
o
C (149

WARNING
BE AWARE THAT REMOVING BAFFLES REDUCES THE UNIT’S
EFFICIENCY AND INCREASE THE OUTLET TEMPERATURE. A
MODIFIED UNIT IS NO LONGER ENERGY STAR APPROVED.
THIS COULD RESULT IN FIRE HAZARD AND/OR OTHER
HAZARDOUS CONDITIONS THAT MAY LEAD TO BODILY HARM.
COMBUSTION &
Install openings and ductwork to the furnace room providing fresh out-
VENTILATION AIR side combustion and circulation air for cooling the furnace casing, as
installation code requires (USA NFPA 31, Canada CSA B139). If
installed in a closed room, provide two free air ventilation openings of at
least 8” x 12” (96 sq. in.) free flow area near ceiling and floor. Oil
burners must have sufficient air to allow vent systems to operate
properly. If balance flue burner his used, combustion air must be duct to
the outside as per instructions.
ELECTRICAL
Wire according to the National Electrical Code (Canadian or USA) or
local codes. Use a separately fused #12 electrical line directly from the
service panel to the furnace junction box. Install a manual shut-off
switch at the door or stairway to furnace room so furnace can be shut off
remotely.
CLEARANCES
Before placing unit, review installation clearances as shown on furnace
operating decal or section PRODUCT INFORMATION (page 4).
