11. This heater is provided with a red alarm light that will illuminate only if the heater has turned off as a result of overheating. If you see the light on, immediately turn the heater off and inspect for any objects on or adjacent to the heater that may have blocked the airflow or otherwise caused high temperatures to have occurred. DO NOT OPERATE THE HEATER WITH THE ALARM LIGHT ILLUMINATING.

12. This heater is intended for comfort heating applications and not intended for use in special environments. Do not use in damp or wet locations such as marine or greenhouse or in areas where corrosive or chemical agents are present.

INSTALLATION INSTRUCTIONS

WARNING

To prevent a possible fire, injury to persons or damage to the heater, adhere to the following:

1. Disconnect all power coming to heater at main service panel before wiring or servicing.

2. All wiring procedures and connections must be in accordance with the National and Local Codes having jurisdiction and the heatermust be grounded.

3. Power supply must enter back box through the knockouts.
   See also TOP marking on the back box for proper orientation.

4. Verify the power supply voltage coming to heater matches the ratings as shown on the heater nameplate.
   CAUTION: ENERGIZING HEATER AT A VOLTAGE GREATER THAN THE VOLTAGE PRINTED ON THE NAMEPLATE WILL DAMAGE THE HEATER AND VOID THE WARRANTY AND COULD CAUSE A FIRE.

5. CAUTION – High temperature, risk of fire, keep electrical cords, drapery, furnishings, and other combustibles at least 3 feet (0.9 m) from front of heater. Do not install heater behind doors, below towel racks, or in an area where it is subject to being blocked by furniture, curtains or storage materials. Hot air from the heater may damage certain fabrics and plastics.

6. To reduce the risk of fire, do not store or use gasoline or other flammable vapors and liquids in the vicinity of the heater.

7. This heater is to be mounted only using back box and may be installed with the back box recessed or surface mounted as described within this manual.

8. The following minimum clearances must be maintained:
   Bottom of heater to floor – 1/4” (6.4 mm).
   Sides of heater to adjacent wall – 12” (305 mm).
   Top of heater to ceiling – 36” (915 mm).

9. Do not operate the heater without the grille installed.

10. Do not use this heater for dry out as the paint, plaster, sawdust and drywall sanding dust will permanently damage the heater and must be kept out of the heater.

NOTE : Heater should be controlled by either built-in thermostat or wall thermostat. Either is purchased separately. A wall thermostat requires a separate feed from heater to thermostat.
HORIZONTAL INSTALLATION ONLY
This heater may be wired with standard building wiring (rated minimum 60° C).

1. Cut a 14 1/4” x 3 5/8” (361.9 mm x 92.1 mm) opening at desired location as shown in Fig. 1. Keep clearance area free of obstructions.

2. Remove top cover from heater enclosure by removing the cover screws.

3. Determine which knockout in enclosure will be used for field wiring and remove (see Figure 1). Install strain relief (field supplied).

4. Fish field wiring through strain relief leaving 6” (12.7 mm) of wire inside box.

5. Make wiring connection, attaching field wiring to two (2) black pigtail leads for 240/208V model, or to black and white pig tail leads for 120V model with wirenuts (provided). Connect field ground lead to ground pigtail with wirenut (provided).
   See Figure 2.
   NOTE: If wall thermostat is used:
   a. A double pole wall thermostat of the type where both poles cycle on and off by temperature change cannot be used with this heater. Only one pole may cycle and this pole must cycle heating element only, not the motor. Cycling both supply leads will defeat fan delay off feature and result in over-heating and possible damage to heater.
   b. Disconnect blue lead from built-in thermostat lead at point A on wiring diagram, Figure 3. Cap off thermostat lead with wirenut. Connect blue lead to field supply lead from load side of thermostat. (See Figure 3). Make remaining field wiring connections per Figure 3.
   CAUTION
   TO PREVENT HEATER DAMAGE OR A POSSIBLE FIRE HAZARD, IF WALL THERMOSTAT IS USED: A DOUBLE POLE WALL THERMOSTAT OF THE TYPE WHERE BOTH POLES CYCLE ON AND OFF BY TEMPERATURE CHANGE CANNOT BE USED WITH THIS HEATER. ONLY ONE POLE MAY CYCLE AND THIS POLE MUST CYCLE HEATING ELEMENT ONLY, NOT THE MOTOR. CYCLING BOTH SUPPLY LEADS WILL DEFEAT FAN DELAY OFF FEATURE AND RESULT IN OVERHEATING AND POSSIBLE DAMAGE TO HEATER.

6. Replace and secure top cover on heater enclosure, and then position heater into opening.

7. Using the holes in the flanges of the enclosure for a template, secure both the front grille and the heater by drilling two .093” (3/32”)(2.3 mm) diameter holes into the cabinet board and installing two No. 6 x 3/4” (No.6 x 19 mm) screws (supplied) through hole “A” (see Figure 1).

OPERATING INSTRUCTIONS

1. Heater must be properly installed before operation.
2. After heater is completely assembled, rotate thermostat knob counterclockwise until control stops. This is the minimum heat setting.
3. Turn power supply to heater “ON” at main switch panel.
4. Heater should not operate. If it operates disconnect power and recheck wiring.
5. Rotate thermostat clockwise until it stops (maximum heat setting).
6. Heater and fan should come on. If heater and fan do not come on, disconnect power and check wiring.
7. Allow heater to continue to operate until room temperature reaches desired comfort level. Then rotate thermostat knob counterclockwise slowly until thermostat clicks off.
8. It may be necessary to readjust thermostat a time or so until exact comfort level is attained. Rotation in the clockwise direction will increase the amount of time the heater will produce heat.
   Rotation in the counterclockwise direction will reduce the amount of time the heater is on.

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. In the full counter-clockwise position the heater will remain off until the room temperature
drops well below freezing.
How To Reset Over -Temperature Safety Control:
This heater is provided with an over-temperature safety control that will turn the heater off if the heater overheats. If this control operates, a red warning light, visible through the front of the grille, will illuminate to alert the owner that the heater is off and requires attention.

WARNING

DO NOT TAMPER WITH OR BYPASS ANY SAFETY LIMITS INSIDE HEATER.

1. Turn the heater off at the thermostat AND disconnect power at the circuit breaker for at least 10 minutes to allow the heater to cool and the safety control to reset.
2. When the heater has cooled, check to see if the heater is blocked or excessively dirty as these conditions may cause overheating. Remove any blockages and /or refer to the Cleaning Heater section for cleaning instructions if dirty.
3. Turn circuit breaker on, reset thermostat to desired setpoint, and verify the heater is operating normally.
4. If the heater malfunctions again and the red light illuminates, disconnect power at the circuit breaker and have the heater inspected by a qualified electrician.

CAUTION

CAUTION – DO NOT CONTINUE TO ATTEMPT TO USE THE HEATER IF THE SAFETY CONTROL REPEATEDLY OPERATES AFTER BEING RESET.
TO DO SO COULD PERMANENTLY DAMAGE THE HEATER OR CREATE A FIRE OR SAFETY HAZARD.

Special Note: In addition to the over-temperature safety control, this heater is provided with a back-up thermal fuse (one shot) that will permanently shut the heater off if for some reason the over-temperature safety control should not function as intended.
If this thermal fuse activates, the heater will not reset and must be repaired by a qualified repair person
