Installation Instructions
IMPORTANT INSTRUCTIONS
When using electrical appliances, basic precautions should al-
ways be followed to reduce the risk of fire, electric shock, and
injury to persons, including the following:
1. Read all instructions before using the heater.
2. The heater is hot when in use. To avoid burns, do not let
bare skin touch hot surfaces. The trim around the heater
outlet becomes hot during heater operation. Keep com-
bustible materials, such as furniture, pillows, bedding, pa-
pers, clothes, and curtains at least 3 ft (0.9 m) from the
front of the unit and keep them away from the sides and
rear.
3. Extreme caution is necessary when any heater is used by
or near children or invalids and whenever the unit is left
operating and unattended.
4. Do not operate any heater after it malfunctions. Discon-
nect power at the service panel and have the heater ins-
pected by a reputable electrician before reusing.
5. Do not use outdoors.
6. To disconnect the unit, turn the controls off, and then
switch off at main power supply panel.
7. Do not insert or allow foreign objects to enter any venti-
lation or exhaust opening as this may cause an electric
shock or fire, or damage to the heater.
8.
To prevent a possible fire, do not block air intake or ex
-
haust in any manner.
9. All electrical heaters have hot and arcing or sparking parts
inside. Do not use in areas where gasoline, paint, or flam
-
mable liquids are used or stored.
10. Do not modify this heater. Use it only as described in this
manual. Any other use not recommended by the manufac-
turer may cause fire, electric shock or injury to persons.
SAVE THESE INSTRUCTIONS
WARNING:
To reduce the risk of fire, do not store or use
gasoline or other flammable vapors or liquids in the vicinity of
the heater.
CAUTION:
High temperature, risk of fire, keep electrical
cords, drapery, furnishings, and other combustibles at least 3
feet (0.9 m) from the front of the heater.
This heater is designed for permanent installation only. Care
should be taken to install according to the following instruc-
tions. All required clearances should be maintained. In addi-
tion all electrical wiring and connections should comply with
local electrical codes.
!
NOTE:
It is extremely important to read all information la-
bels. Care must be taken to ensure that the heater is rated the
same voltage as the electrical supply wires. Failure to do so
could result in unsafe heater operation as well as damage to the
unit. If replacing an existing heater, check the labels of the old
heater to ensure the voltage of the new heater is compatible.

NOTE:
Maintain a minimum clearance of 8” from adjacent
walls, floors and ceilings on all four sides of the grille
All units should be controlled by means of a regulating ther-
mostat. Certain models only are provided with built in ther-
mostats. Check the
Model Key Information
section for veri-
fication. Wall thermostats should comply with the voltage and
wattage of all heaters on the circuit.
All installations require the following components:
1) Recess Box (Model 1011650100)
2) Heater Assembly (See nameplate Label)
3) Grille
An optional Surface Mount Box is available for installations
that are not recessed in wall cavity.
Step 1 – Placement
All units are designed for placement in either interior or ex-
terior walls. Care should be taken to provide a minimum of
8" clearance from floors, ceilings and adjacent walls. Once
installed, the airflow through the heater should not be blocked
in any way. Maintain 3’ (91.4cm) clearance of objects from the
front of unit. Maintain a spacing of 3’ (91.4cm) between heat-
ers in order to prevent re-circulation of heated air. Insulation
surrounding the back and sides of the recess mount box will
not affect performance. Ensure insulation is rated for tempera-
tures up to 185°F (85°C).

ticularly those incorporating clear vinyl materials tend to distort
at temperatures in the vicinity of 140°F (60°C). Material shall
be checked prior to installation to determine if discoloration
will occur. Units are not approved for placement in floors or
ceilings. Do not install in any area where combustible vapors,
