WARNING
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 considerable time and money later. Observe the following procedures, and cut your installation 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.
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 combustible materials, such as crates, drapes, etc., away from heater. Do not install behind doors, 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 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.
SAVE THESE INSTRUCTIONS
!
CAUTION
!
FOR SAFE OPERATION AND REDUCED RISK OF FIRE,
INJURY OR HEATER DAMAGE, OBSERVE THE
FOLLOWING:
1. Do NOT use a remote thermostat with this heater. Built in thermostat cycles the heating element only. Fan delay control automatically turns fan ON and OFF, and provides a fan delay OFF feature to remove residual heat after thermostat has turned heating elements off. Wiring of heater in any manner which defeats the fan delay OFF feature can result in overheating and permanent damage to heater, and will void the warranty.
2. For wall mounting only with air discharge downward. Do
NOT install in floor, ceiling, upside down(air discharge upward), or sideways.
3.Do NOT operate heater without grille installed.
4.Maintain the following clearances:
•Bottom of heater to floor – 8” (203mm)
•Sides of heater to adjacent wall – 8” (203mm)
•Top of heater to ceiling – 36” (915mm)
5.This heater is hot when in use. Do NOT install heater behind door, behind towel rack, inside closet, where drapery could touch heater or be damaged by heat, or where airflow to heater may be obstructed. Keep electrical cords, bedding, furniture, and other items away from heater.
6.Heater must be cleaned periodically (at least annually) to assure proper performance and prevent overheating. See section on cleaning and maintenance.
e. Ground the back box using the green screw located in the inside top of the box.
f. Secure disconnect switch bracket in place by tightening screws.
Installation of Recessed Back Box in Existing Construction
1.Provide a wall opening 14-1/2" (362mm) wide by 18-1/2"
(470mm) high at the desired mounting height, but no closer than 8" (203mm) to floor (See Figure 2).
2.Power Supply Wiring
Note: Wiring Compartment Volume - 119in 3 (1950cm 3 ).
a. Run a power supply cable into the area above the top of the wall opening. All wiring must be in accordance

2.Power Supply Wiring (See Figure 1)
Note: Wire compartment volume - 119in 3 (1950cm 3 ).
a. Run a power supply cable into the knockout area in the upper right hand corner of the back box. All wiring must be in accordance with National and Local Electrical
Codes. Refer to Table 1 for correct wire size.
b. Remove disconnect switch bracket by loosening two screws on the right side.
c. Install a cable clamp in the “knockout” in the top of the back box.
d. Insert power supply cable through cable clamp, allowing at least 6" (152mm) of leads to extend inside the back box. Connect the blue lead wires of disconnect switch to the supply wire leads using wire connectors
(see wiring diagram, pg. 3).

1 for correct wire size.
b. Remove disconnect switch bracket by loosening the two screws on the right side.
c. Install a cable clamp in the “knockout” in the top of back box.
d. Insert power supply cable through cable clamp, allowing approximately 6" (152mm) of cable length to remain inside the back box to facilitate connections.
3.Mounting Back Box a. Place the back box into wall opening flush with finished wall surface on bottom and sides of box. (Top flange of back box should protrude approximately 1/2" or 12.7mm from finished wall surface).
b. Secure the back box in place with wood screws or nails.
4.Wiring Disconnect Switch a. Connect the power supply wires to the blue wires of the disconnect switch using wire connectors (see wiring diagram, pg. 3).
b. Ground the back box using the green ground screw located in the inside top of the box.
c. Secure disconnect switch bracket in place by tightening screws.
Installation of Back Box with
Surface-Mounting Frame
(See Figure 3)
1.Secure back box to wall with knockouts in upper right hand corner using screws and anchors.
2.Hang the surface-mounting frame on the back box.
Ensure that the back edge of the surface-mounting frame is flush against the wall.
NOTE: If heater is located in a high traffic area, where it may be subjected to vandalism or abuse, take extreme care to see that the box is firmly attached to the wall.

a. Run a power supply cable into the area of the upper right corner of the mounting frame. Arrangement of wiring to this point must be in accordance with national and local codes. Refer to specifications on page 2 for proper wire sizes.
NOTE: If the wiring is to run through the wall, cut a hole in the area of the top of the backbox. Run the supply wire through this hole. Then remove the “knockout” from the top of the box and proceed to step C.
b. Remove the “knockout” on the top side of the frame.
c. Remove disconnect switch bracket by loosening the two screws on the right side.
d. Feed the power supply cable through the frame allowing 6" (152mm) of lead to remain inside the back box
(using cable clamp, connector, or other suitable strain relief).

Operation
1. Rotate the thermostat fully clockwise. This should energize the heating elements and cause warm air to flow from the hot air discharge at the openings in the bottom of the grille.
2. After the operation check, rotate the thermostat to the desired position to obtain room comfort.
NOTE: For best results, the heater should be left “ON” constantly during the heating season because the thermostat, when properly set, will maintain the desired temperature.
Cleaning & Maintenance
To maintain optimum performance and efficiency, heater should be cleaned and checked periodically. It is recommended the heater be cleaned at least annually. (more often if used in a dirty environment)
!
CAUTION
!
TO PREVENT POSSIBLE ELECTRIC SHOCK, ALWAYS DISCON-
NECT ALL POWER TO HEATER AT MAIN DISCONNECT PANEL
OR FUSE BOX BEFORE CLEANING OR MAINTENANCE TO
HEATER.
To Clean Heater:
1. Disconnect power to heater at main panel or breaker.
2. Remove thermostat knob (if provided) and remove front cover (grille) as follows: (See figure 4)
–Insert screw driver through bottom louver and loosen one screw that holds latch mechanism.
–Lift front cover upward and pull top outward to remove.
3. Push ON/OFF switch to OFF position.
4. Using vacuum cleaner knozzle, brush, or dust cloth, remove dust and any foreign material from heater. Use care to not bend fan blade or damage heater wiring. (Spin blade by hand to make sure it turns freely.)
5. Push ON/OFF switch to ON position.
6. Replace front cover and secure latch mechanism. (See installation of heater Assembly and Grille.)
7. Reconnect power to heater and verify that heater operates properly.
TO RESET MANUAL RESET LIMIT:
Your heater is equipped with a manual reset safety thermal limit control that will automatically turn the heater off to prevent a fire if the heater overheats. This control is located on the fan panel assembly between the element and fan blade and marked
“reset”. The red reset button can be seen through the front grille when the heater is installed. To reset, allow the heater to cool, then push the red button that is visible through the hole in the fan panel. The heater should immediately return to normal operation.
