1. To prevent electrical shock, 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
as a precaution against possible electric shock.
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.

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 (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

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 manual 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 faceplate under the knob has a “finger-proof” clear Mylar covering which can be removed for a shiny appearance.
INST ALLATION
NOTE: Unit may be installed vertically or horizontally in the wall
stud space. This unit is for wall mounting only. A 14 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. HORIZONTALMOUNTING: (See Figure 1B)
a. MAKE SURE THAT OUTLET CORNER IS A T THE TOP
RIGHTHAND CORNER. In new construction place roughin 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 roughin 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 OUTLETCORNER 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 conjunction with these instructions.

OPERA TION
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. T o decrease, turn counterclockwise.
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 immedi
ately 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 cooldown 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.
