INSTALLATION INSTRUCTIONS
Congratulations on purchasing a small wall heater from Dimplex North America. Your heater is manufactured using the highest quality materials and
workmanship and will provide many years of trouble free service. This heater is designed for permanent installation only, care should be taken to
install according to the following instructions. All required clearances should be maintained, in addition all electrical wiring and connections should
comply with local electrical codes.
Note : It is extremely important to read all information labels. 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.
All units should be controlled by means of a regulating thermostat,certain models only are provided with built in thermostats, check the Model Key
Information section for verification. Wall thermostats should comply with the voltage and wattage of all heaters on the circuit. Built in thermostats
are not suitable for Register Grille Models.
All installations require the following components
1) Recess Mount Box ( Model 6100831000 )
2) Heater Assembly ( See nameplate Label )
3) Grille ( Either Multi- Directional Style or Register Style )
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 exterior 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 3ft clearance of objects from
the front of unit. Maintain a spacing of 3ft between heaters 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 temperatures up to 85
o
C.
Note: Certain flooring and wall covering materials ( particularly those incorporating clear vinyl materials tend to distort at temperatures in
the vicinity of 60 C ( 140 F ). 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, gases, dusts or liquids are present. Fire or
explosion may occur.
STEP 2 – Mounting The Recess Box
Determine the desired orientation of unit. Provide an opening in wall 14 ¼” x 7 5/8" x 3 3/8" deep minimum. Care should be taken to install the
recess box in the correct orientation to accommodate grille. Note the position of the electrical entry knockouts and orient recess box according
to Figure # 1. Ensure all required clearances are met.
Ensure recess box flanges are flush with the finished wall surface. For new construction, the sides of the recess box are marked with guidelines
to allow for ½” and 5/8 “ drywall thickness if drywall is to be added at a later date. Secure recess box to studs with screws using holes provided on
sides or flange of recess box. Remove appropriate electrical knockout and secure supply wire using an approved strain relief connector leaving 6" of
wire leads in the recess box.
STEP 3 - Mounting the Heater Assembly
Insert the heater assembly into the recess box ensuring that the tab on the heater assembly slides into the slot in the recess box. Ensure the heater
assembly is fully seated and secure to the recess box using the captive screw provided.
STEP 4 –Electrical Connections
Route supply wires from circuit breaker through wall thermostat to heater. For models with built in thermostat route from circuit breaker to heater.
Supply wire must be of two wire plus ground variety, with a rating capable of handling all heaters on the circuit. Supply wire should be rated for a
minimum of 60C. Make electrical connection according to relevant diagrams shown on Figure # 2. Make connections using approved wire nut
connectors and secure the grounding wire to the green ground screw on the heater chassis. On models with Register Style Front Grills only, a
terminal box cover plate is provided. Insert the tabs of the cover plate into the slots and secure the other side of plate with the screws provided.
STEP 5 – Secure the Front Panel
If your unit has a built in thermostat remove the plug on the front panel. Fasten the Front Grill using the screws provided. It is important to note that
the front grill is oriented in the required positions shown in Figure # 1 and on the Multi – Directional grille, the larger louvered portion is placed over
the fan blade portion of the heater. For units with built in thermostat push knob onto thermostat shaft through plug hole.
Operation And Maintenance
For units with built in thermostats, rotate the thermostat knob fully clockwise. Heater should activate. When the room reaches the desired
temperature, slowly rotate the knob counterclockwise until unit shuts off. The heater will automatically cycle around this preset temperature setting.
All units contain an Automatic Reset High Temperature Cutout, which will shut the heater off in the event of abnormally high operating temperatures.
In addition a Red Warning Light will activate providing a visual warning. If this condition exists, disconnect all power to the unit and call a licensed
electrician for service. Do not use heater until the problem is determined and corrected. ENSURE POWER TO THE UNIT IS DISCONNECTED
