Installation & Maintenance Instructions
Read Carefully -
These instructions are written to help you
prevent difficulties that might arise during installation of
heaters. Studying the instructions first may save you con-
siderable time and money later. Observe the following pro-
cedures, and cut your mounting time to a minimum. TO
REDUCE RISK OF FIRE OR ELECTRIC SHOCK:
1. Disconnect all power coming to heater at main service panel
before wiring or servicing.
2. All wiring must be in accordance with the National and Local
Electrical Codes and the heater must be grounded.
3. Verify the power supply voltage coming to heater matches the
ratings printed on the heater nameplate before energizing.
4. This heater is hot when in use. To avoid burns, do not let bare
skin touch hot surfaces.
CAUTION
1. THE HEATER MUST BE MOUNTED AT LEAST 6' (182.8 cm) or
(1.83 m ) ABOVE THE FLOOR TO PREVENT ACCIDENTAL CONTACT.
2. TO PREVENT POSSIBLE OVERHEATING OR DAMAGE DUE TO
OVERHEATING, REFER TO FIGURES 1 AND 4 FOR SIDE, TOP,
AND BOTTOM CLEARANCE REQUIREMENTS.
GENERAL
When installing 2 or more heaters along one wall:
1. Mount heaters allowing adequate spacing between heaters as
shown in Table 1.
2. Install optional RCCSPC Splice Plate (if desired) per instructions
provided with RCCSPC.
When mounting heaters end to end add the "maximum allowable
expansion" of each heater and provide that clearance from end to end
of units. See Table 1.

WARNING
5. Do not insert or allow foreign objects to enter any ventilation or
exhaust opening as this may cause an electric shock, fire,or
damage to the heater.
6. Do not block air intakes or exhaust in any manner. Keep com-
bustible materials, such as crates, drapes, etc., away from
heater. Do not install behind door, furniture, towels, or boxes.
7. A heater has hot and arcing or sparking parts inside. Do not use
it in areas where gasoline, paint, or flammable liquids are used
or stored.
8. Use this heater only as described in this manual. Any other use
not recommended by the manufacturer may cause fire, electric
shock, or injury to persons.
9. This heater is not approved for use in corrosive atmospheres
such as marine, green house, or chemical storage areas.
For 450 to 1200 Watt Heaters:
1. Select correct mounting distance from the ceiling material per
Figure 1. Using Table 1, determine the center to center distance
of the end wall brackets for the particular model (wattage) to be
mounted. Divide this value by 2 to determine the approximate
location to mount the center wall bracket. Mark these locations on
the chosen wall. Locate a stud nearest the center wall bracket
mark. Use this stud for the bracket location. (Disregard original
mark mentioned above) Assemble end wall brackets as shown in
Figure 3.
2. Using the template (provided), align the top of the template with
the ceiling and the center of the pre-punched holes with the
bracket marks on the wall. Choosing the proper ( end or middle)
bracket location holes, mark the bracket pilot hole locations using
the selected pre-punched holes provided on the template. With
the fasteners provided, mount the assembled end wall brackets
and center wall bracket to the wall. Using a tape measure, deter-
mine the distance between the center (slot) of the left end wall

location on the cove heater.
40.75" (1,035mm)
52.75" (1,340mm)
3. Orient the cove heater face down on a protective flat surface.
64.75" (1,645mm)
Using the value recorded in step 2, measure this distance from
76.75" (1,949mm)
the left end of the cove heater and mark this location on the back
87.75" (2,229mm)
surface of the panel. Slide the center support bracket to the
111.75" (2,838mm)
marked position on the panel, aligning the center of the bracket
125.75" (3,194mm)
with this mark.
