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 y les the heating element only. Fan delay
ontrol automati ally 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 whi h defeats the fan delay OFF
feature an result in overheating and permanent dam-
age to heater, and will void the warranty.
2. For wall mounting only with air dis harge downward. Do
NOT install in floor, eiling, upside down(air dis harge
upward), or sideways.
3.Do NOT operate heater without grille installed.
4.Maintain the following learan es:
•Bottom of heater to floor – 8” (203mm)
•Sides of heater to adja ent wall – 8” (203mm)
•Top of heater to eiling – 36” (915mm)
5.This heater is hot when in use. Do NOT install heater
behind door, behind towel ra k, inside loset, where
drapery ould tou h heater or be damaged by heat, or
where airflow to heater may be obstru ted. Keep ele tri-
al ords, bedding, furniture, and other items away from
heater.
6.Heater must be leaned periodi ally (at least annually) to
assure proper performan e and prevent overheating. See
se tion on leaning and maintenan e.
!
!

NOTE: If heater is lo ated in a high traffi area, where it may
be subje ted to vandalism or abuse, take extreme are to see
that the box is firmly atta hed to the wall.
3.Power Supply Wiring
NOTE: Wiring Compartment Volume - 119in3(1950 m3).
a. Run a power supply able into the area of the upper
right orner of the mounting frame. Arrangement of
wiring to this point must be in a ordan e with nation-
al and lo al odes. Refer to spe ifi ations on page 2 for
proper wire sizes.
NOTE: If the wiring is to run through the wall, ut a hole
in the area of the top of the ba kbox. Run the supply wire
through this hole. Then remove the “kno kout” from the
top of the box and pro eed to step C.
b. Remove the “kno kout” on the top side of the frame.
. Remove dis onne t swit h bra ket by loosening the
two s rews on the right side.
d. Feed the power supply able through the frame allow-
ing 6" (152mm) of lead to remain inside the ba k box
(using able lamp, onne tor, or other suitable strain
relief).
e. Se ure the power supply able to the ba k box
(using able lamp, onne tor, or other suitable strain
relief) allowing 6" (152mm) of lead to remain inside the
ba k box.
f. Conne t supply wires to blue wires of dis onne t
swit h using wiring onne tors (See wiring diagram,
pg. 3).
g.Ground the ba k box by onne ting the supply ground
leadwire to the green ground s rew lo ated in the
inside top of the box.
h.Se ure dis onne t swit h bra ket in pla e.
Installation of Heater Assembly and Grille
After ba k box is ompletely installed and no further on-
stru tion dirt is expe ted, lean debris from ba k box, remove
heater assembly from its arton. Refer to Figure 4 and pro-
eed as follows:
1. Insert the heater assembly into ba k box, pla ing
the four mounting holes (with key-hole slots) over the
s rews in the box. Tighten all s rews se urely.
2. If surfa e-mounting frame is used, ensure that the
frame is even with all four heater assembly tabs before
tightening s rews.
3. Conne t the two dis onne ted swit h wires to the heat-
ontrol swit h (thermostat) leads using wirenuts (see
wiring diagrams, pg. 3) After onne tion, push wires ba k
into the opening.
4. Turn thermostat to the extreme ounter lo kwise
position.
5. Push dis onne t swit h into ON position.
6. Lat h at bottom of heater assembly should be in up
position.
7. Mount grille over tabs on fan de k and push down until
grille is se ure.
8. Insert s rewdriver through bottom louver in grille and
loosen s rew while holding bottom of grille against

Operation
1. Rotate the thermostat fully lo kwise. This should
energize the heating elements and ause warm air to
flow from the hot air dis harge at the openings in the bot-
tom of the grille.
2. After the operation he k, rotate the thermostat to
the desired position to obtain room omfort.
NOTE: For best results, the heater should be left “ON”
onstantly during the heating season be ause the ther-
mostat, when properly set, will maintain the desired
temperature.
Cleaning & Maintenance
To maintain optimum performan e and effi ien y, heater should
be leaned and he ked periodi ally. It is re ommended the
heater be leaned at least annually. (more often if used in a
dirty environment)
To Clean Heater:
1. Dis onne t power to heater at main panel or breaker.
2. Remove thermostat knob (if provided) and remove front
over (grille) as follows: (See figure 4)
–Insert s rew driver through bottom louver and loosen one
s rew that holds lat h me hanism.
–Lift front over upward and pull top outward to remove.
3. Push ON/OFF swit h to OFF position.
4. Using va uum leaner knozzle, brush, or dust loth, remove
dust and any foreign material from heater. Use are to not
bend fan blade or damage heater wiring. (Spin blade by
hand to make sure it turns freely.)
5. Push ON/OFF swit h to ON position.
6. Repla e front over and se ure lat h me hanism. (See
instal- lation of heater Assembly and Grille.)
7. Re onne t 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
ontrol that will automati ally turn the heater off to prevent a fire
if the heater overheats. This ontrol is lo ated on the fan panel
assembly between the element and fan blade and marked
“reset”. The red reset button an be seen through the front grille
when the heater is installed. To reset, allow the heater to ool,
then push the red button that is visible through the hole in the fan
panel. The heater should immediately return to normal operation.
