PLACEMENT
Room heating units can normally be placed on standard flooring systems with any type of covering, i.e.
wood floor, carpet, linoleum; but, heater weight must be considered. If in doubt, consult a building contrac-
tor or an architect. (Refer to the Heater Specifications section in this manual for weight and physical dimen-
sions of the room heating unit being installed.)
When installing on extremely thick carpet, it may be necessary to slightly elevate the heater to avoid carpet
contact with the air discharge grill. The carpet should not come within ¾ inch of the air discharge grill
openings.
Heaters can be placed on an outside or inside wall. Best operating efficiency will be achieved by placing it
along an inside wall, adjacent to an outside wall. Avoid installing the heater near sources of extreme heat or
cold so the built-in room temperature sensor can sample proper room air temperature. It is also best to not
place the heater near an open stairwell.
CLEARANCE REQUIREMENTS
Allow a minimum of 1½ inches of clearance from the sides and back of the heater and a minimum of 3
inches from the top of the heater. The factory supplied wall mounting bracket, located on the heating unit's
shipping pallet, will provide the correct wall-to-back-of-heater clearance. If the heater is a 120V plug-in
model with a security base, the base will provide the proper wall-to-back-of-heater clearance. The base is
packaged inside the shipping box on the back side of the heater.
If enclosing the room heating unit in a wooden cabinet or recessing the room heating unit into a wall, allow 2
inches clearance on sides and 4 inches on top. Do not enclose or otherwise obstruct access to the heater's
front panel and grill. Objects such as curtains, furniture, or bed covers must be kept a minimum of 4 inches
from all room heating unit surfaces and 15 inches from the grill.
If there is less than a 12 inch clearance on the right side of the room heating unit, we recom-
mend installing a remote wall mounted room temperature sensor. (Order item #1302024.)
ELECTRICAL CONNECTIONS
Line voltage connections for direct wired room heating units
Heaters that are designed for direct wired connections are equipped with flexible conduit installed in the
room heating unit’s back panel. This conduit is pre-wired for ease of field connections. The wiring in the
conduit may not be the same size as the field wiring conductors.
Direct wired heaters are capable of being connected to more than one branch circuit. One or two charging
circuits may be utilized depending on room heating unit size (See Table 2). Each room heating unit is
capable of being connected with a separate blower and element circuit or with one circuit for blower and
element operation. To determine the correct wire sizes for the room heating unit being installed, refer to the
Unit Identification Label on the lower left side panel. (See Figure 11. Table 1 and Table 2 will also provide
information on conductor sizing.)
Never install Class II (low voltage) wiring or any wiring in a line voltage area unless the wire
is rated for line voltage.
