ELECTRIC SHOCK OR FIRE HAZARD
Selecting A Location For Your Heater: KT
This heater has been designed to allow it to be recessed at floor
level in the toe space of cabinets or under counters or at the base
of walls. When selecting the location, be sure the materials that
will be located in the air heated by this heater (such as floor cover-
ings) will not distort or discolor at temperatures above 140°F
(60ºC). DO NOT select a location directly beneath sinks or other
work areas where people are likely to stand for extended periods of
time. DO NOT install less than 6" (15cm) from vertical side walls or
open edge of door. This heater must have an unrestricted airflow.
DO NOT select a location where it is likely to be blocked by furni-
ture, throw rugs, etc. Be sure the location selected allows sufficient
space for the heater as shown by Table 1. DO NOT locate this heat-
er in an area where combustible vapors, gases liquids, or excessive
lint, dust or moisture is present.

TABLE 1
Specific to KT Series:
The KT heater is intended for a toe space installation only. Other
grilles are available for a flush surface mount installation that will
trim out the wall can. The heater is designed to be installed in the
toe-space of a cabinet with a minimum of 2" overhang to maximum
7" of overhang. Shorter overhangs may overheat the floor where
longer than 7" overhangs may overheat the cabinet door area.
The wire and breaker sizing chart will give a general rule of installa-
tion size. Consult an electrician if you are not knowledgeable about
wiring codes.

specified on the nameplate.
3.
Wiring procedures and connections shall be in accordance with
all National and local codes having jurisdiction.
4.
Remove the two screws holding the grille in place & set grille
aside retaining the screws.
5.
Removing the two screws holding the cover in place on each
side of the heater will allow you access to the wiring compart-
ment.
6.
A knockout of 1/2 inch conduit size (7/8 inch / 2.2cm) is pro-
vided in the back and side of the heater for power to enter.
Provide proper conduit connectors for your flexible connec-
tions.
7.

wire nut.
8.
Assemble all covers on electrical and apply power. Test unit by
turning thermostat up past room temperature. You will see a
puff of smoke as the elements are energized and the fan turns
on. This is a normal burn off of manufacturing lubricants and
will dissipate in 5 minutes.

Heater will continue to run until the room temperature you set
is reached and then turn itself off until the temperature drops
again.
