MOUNTING

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property dam- age. Heater must be installed or serviced by a qualified person in accordance with the National Electrical Code, NFPA 70.

1.Locate on vertical wall with length of heater positioned horizon- tally.

2.When selecting a mounting location, the following minimum dis- tances must be observed:

A.6” from bottom of heater to floor to allow for adequate air flow through the heater.

B.6” from wall or other obstruction to right side of heater to allow for access to 1/4 turn fasteners.

C.12” from wall or other obstruction to left side of heater to allow for access to controls and wire entry.

3.Avoid mounting heater in a recess since such mounting interferes with free air circulation, increases heater temperatures, and pre- vents proper thermostat operation.

4.Remove front cover by giving two fasteners on right end of heater 1/4 turn then sliding cover approximately 1” to right, then lifting.

5.At the correct height for the top of the heater, draw a pencil line on the wall, parallel to the floor.

6.Using dimensions shown in Figure 1, mark the mounting slot loca- tion on the wall.

7.Mount heater to the wall by using fasteners (not furnished) to suit the wall construction. Four 5/16 x 1” mounting slots are provided in heater back panel. Note: If wall surface is not flat, resulting in gap between rear case and wall in excess of 1/8” at location of fas- teners, use metal washers to fill in gap. Tighten left hand fasteners securely. The right hand fasteners should be pulled up snug to allow for movement during operation to avoid expansion noise.

8.Replace cover and tighten 1/4 turn fasteners.

WIRING

ELECTRIC SHOCK HAZARD. Any installation involving electric heaters must be performed by a qualified person and must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard.

Note: Electrical wiring is to be in accordance with the National Electrical Code and local codes by a qualified person using at least 75°C (167°F) type RH, THW or equivalent insulated conductors.

1.Electrical wiring can be brought into heater through 3/4” knockout located either in back panel or bottom of left hand end of heater (wiring compartment).

2. Grounding conductor with green insulation, should be secured into grounding lug located in wiring compartment.

3.Using Wiring Diagram Table B select applicable wiring dia- gram (Figure 2-9) for proper method of connecting heater.

4.Two or more Type HCH heaters may be controlled by a com- mon fused disconnect switch providing total branch circuit cur- rent does not exceed 48 amperes according to National Electrical Code.
