GENERAL
Cove heaters are designed to provide years of efficient trouble-free operation as a supplemental heat source for comfort heating in residential and commercial applications. Cove heaters must be controlled with a thermostat for efficient, safe operation. A thermostat is not included with this heater. Cove heaters can be connected to any single or double pole line voltage thermo- stats that will meet the electrical load requirements. See Accessories.

When installing 2 or more heaters along one wall:

CAUTION
THE HEATER MUST BE MOUNTED AT LEAST 6′ (182.8 CM) OR (1.83 M ) ABOVE THE FLOOR TO PREVENT ACCIDENTAL CONTACT.

Mount heaters allow adequate spacing between heaters as shown in Table 1.
Install optional RCCSPC Splice Plate (if desired) per instruc-tions 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.

MOUNTING THE HEATER
For 450 to 1200 Watt Heaters:

Select the correct mounting distance from the ceiling material per Figure 1. Using Table 1, determine the center-to-center dis-tance 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 centre wall bracket. Mark these locations on the chosen wall. Locate a stud near the centre wall bracket mark. Use this stud for the bracket location. (Disregard the original mark mentioned above) Assemble end wall brackets as shown in Figure 3.
Using the template (provided), align the top of the template with the ceiling and the centre 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 centre wall bracket to the wall. Using a tape measure, determine the distance between the centre (slot) of the left-end wall bracket and the hook of the centre wall bracket. Add 3-5/8 inches (92 mm) to this value and record it for the centre support bracket location on the cove heater.
Orient the cove heater face down on a protective flat surface. Using the value recorded in step 2, measure this distance from the left end of the cove heater and mark this location on the back surface of the panel. Slide the centre support bracket to the marked position on the panel, aligning the centre of the bracket with this mark.
4. To mount the cove heater, attach the centre support bracket to the centre wall bracket by tilting the heater back and allowing the upper slot to fall onto the bracket hook per Figure 2. Attach the junction boxes to the end wall brackets in a similar manner. Bring the cove heater forward to lock it into place.

For 1500 to 1800 Watt Heaters:
The 1500 & 1800-watt cove heaters require the additional support of (2) centre wall brackets due to the extra length. The mounting steps are similar to the 450 to 1200-watt cove heater with the following exceptions:

After the approximate centre location between the end wall brackets has been determined, measure 30 inches (762 mm) on each side of this location to determine the approximate location to mount the centre wall brackets. Locate a stud nearest each mark. Use these studs for the centre wall bracket locations. (Disregard original 30-inch location marks)
Using the provided template, align the top of the template with the ceiling and the centre of the pre-punched holes with the bracket marks on the wall. Choosing the proper 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 brack-ets and centre wall brackets to the wall. Measure the dis-tance between the centre (slot) of the left end wall bracket and the hook of the left centre wall bracket. Add 3-5/8 inches (92 mm) to this (left end) value and record it for the left centre support bracket location on the cove heater. Determine the distance between the centre of the right end wall bracket and the hook of the right centre wall bracket. Add 3-5/8 inches (92 mm) to this (right end) value and record it for the right centre support bracket placement on the cove heater.
Orient the cove heater face down on a protective flat surface. Using the left end value recorded in step 2, measure this dis-tance from the left end of the cove heater and mark this location on the back surface of the panel. Using the right end value recorded in step 2, measure this distance from the right end of the cove heater and mark this location on the back surface of the panel. Slide the centre support brackets to the marked positions on the panel, aligning the centre of the brackets with each mark.
To mount the cove heater, attach centre support brackets to the centre wall brackets by tilting the heater back and allowing the upper slot to fall onto the bracket hook per Figure 2. Attach the junction boxes to the end wall brackets in a similar manner. Bring the cove heater forward to lock it into place.
The cove heater can be wired from either end of the heater. Install a cable clamp (supplied by others) in one of the knockouts located in the back of the junction boxes you plan to use. Insert the power supply cable through the cable clamp allowing approximately 6” (152mm) of cable length to remain inside the box to facilitate wiring. Add at least 2 inches of cable loop between the wall and knockout entering the junction box to allow for heater expansion.
Refer to wiring diagrams.
Attach end caps (found in the parts bag) as shown in Figure 3.

INSTALLATION AT CORNER
Heaters must be located so that the ends of each heater are 4 inches (102 mm) from the side wall. See Figure 4.

OPERATING INSTRUCTIONS

The heaters are intended to be controlled by a remote wall-mounted thermostat. The thermostat should be located in the same room on a side wall. It should also be five feet above the floor, but not directly under the heater.

The heater must be properly installed before operation.
Turn the power supply to the heater “ON” at the main switch panel.
Where applicable, refer to control accessory instructions regarding the operation of any controls used with the heater.
- NOTE: For some time after the heaters are put into opera-tion the owner may notice a “new smell” coming from the heaters. This is expected on new installations and will dissipate after approximately 24 hours of operation.
- NOTE: For best results, the heater should be left “ON” constantly during the heating season as the thermostat, when properly set, will maintain the desired temperature.
