UNPACKING
Unpack carefully. Inspect for loose, missing or damaged
parts. In the event of missing components or hidden damage
immediately contact your distributor or the delivering carrier
concerning discrepancies. The motor / fan assembly has
been carefully factory balanced. Care should be taken when
handling to avoid damage resulting in unnecessary vibration
and noise.
GENERAL
The wall heaters provide fast supplemental room heat. The
fan draws cool air in through the round opening in the grille
frame and directs it across the nickel chromium elements for
discharge through the rectangular top opening. An over-heat
protective device automatically shuts the heater OFF if the
discharge is blocked or an unsafe temperature rise is
encountered for any reason. Heaters are equipped with man-
ual reset thermal over-heat protectors. On some models, the
manual reset is backed-up with a thermal fuse. The grille is
“finger-proof”” and can be removed for cleaning. The face-
plate under the knob has a “finger-proof” clear Mylar cover-
ing which can be removed for a shiny appearance.
INSTALLATION
NOTE: Unit may be installed vertically or horizontally in the wall
stud space. This unit is for wall mounting only. A14 1/2 x 9” wall
opening is required. If recess mounting is impractical, use 414
surface mounted housing (not furnished).
Bottom of heater should be a minimum of 18 inches above
finished floor.
1. HORIZONTAL MOUNTING: (See Figure 1B)
a. MAKE SURE THAT OUTLET CORNER IS AT THE TOP
RIGHT HAND CORNER. In new construction place rough-
in box between studs at desired height, and using wood
screws, secure it to studs, making sure that outer edges
will be flush with finished wall. Bring in service lead through
proper knock-out hole and attach ground lead to screw
provided.
b. For installation in existing walls, select desired location,
ascertain location of studs and cut away wall using rough-
in box as a pattern for hole size. Bring in service lead
through proper knock-out hole and attach ground lead to
screw provided. THEN, secure rough-in box to studs
keeping outer edges flush with wall surface.
2. VERTICAL MOUNTING (See Fig. 1C)
a. MAKE SURE THAT OUTLET CORNER IS AT THE
BOTTOM RIGHT HAND CORNER. Toe-nail two 2 x 4”
headers, 14-3/8 inches apart at desired height (see Fig. 2).
b. Proceed as outlined in step 1a or 1b above.
3. Connect service leads to heater (see Figure 4 or 5). Make
sure all wiring conforms to National Electrical Code as well as
all applicable local codes.
4. Assemble heater into rough-in box using the four screws
supplied (see Figure 3).
SURFACE MOUNTING
If surface mounting adapter 414 is used to mount this heater,
follow mounting instructions packed with the adapter in con-
junction with these instructions.

OPERATION
1. Set the thermostat to its fully clockwise position.
2. When room reaches comfort level, turn thermostat knob
counter-clockwise until the heater cuts off. Heater will cycle
automatically around this present temperature. To increase
temperature, turn knob clockwise. To decrease, turn counter-
clockwise.
3. This unit is equipped with a manual-reset, high temperature
limit switch. If no heat is delivered with thermostat fully
clockwise, check reset button in center of grille. Push red
button in with a toothpick or similar piece of wood. If reset
kicks back out immediately or will not stay in, have heater
checked by a qualified electrician.
LIMIT SWITCH
1. This unit is equipped with a manual-reset, high temperature
limit switch. If no heat is delivered with the thermostat set fully
clock-wise, turn thermostat fully counterclockwise, and check
red reset button in center of front plate.
2. In order for the heater to operate, the limit switch must be reset.
Using a toothpick or similar piece of wood, push button IN
where it should remain.
3. Turn thermostat fully clockwise and repeat above steps when
heater resumes normal operation.
4. If heater still does not function, or if after a 10-20 minute cool-
down period the button will not reset (remain IN), have the
heater checked by a qualified electrician.
NOTE: Due to the sensitivity of the limit switch, it may have
tripped from vibration during shipment. It may be necessary
to reset switch prior to initial start-up of the heater.
MAINTENANCE — Six Months

before attempting any maintenance or repairs. Lock or tag
circuit breaker panel door. Failure to do so could result in
serious electrical shock, burns or possibly death.
a. Loosen screws securing heater assembly to housing and
remove heater assembly.
b. Vacuum or wipe dust from inside of heater. Take caution not to
