WARNING WARNING WARNING WARNING
Before installing and operating this product, the user and/or installer must read, understand and follow these instructions and keep them handy
for future reference. If these instructions are not followed, the warranty will be considered null and void and the manufacturer deems no further
responsibility for this product.
This product must be installed by a qualified person and connected by a certified electrician, according to the electrical and building
codes effective in your region.
The following instructions must be adhered to in order to avoid personal injuries or property damages, serious injuries and potentially fatal
electric shocks.
Protect the heating unit with the appropriate circuit breaker or fuse, in accordance with the nameplate.
Make sure the line voltage (volt) is consistent with that indicated on the unit’s nameplate.
This unit must be grounded.
Switch off the power at the circuit breaker/fuse before installing, repairing and cleaning the unit.
Make sure the unit is appropriate for the intended use (if needed, refer to the product catalog or a representative).
Recommended heating capacity :
1.25 W/cubic foot (0.03 m³).
It corresponds to 10 W/square foot (0.09 m²) based on a standard ceiling height of 8 feet (2.44 m). The recommended capacity is usually
sufficient for normal heating needs. Please note that the insulation quality of walls and windows are some of the factors that influence heat
losses, which modify the required capacity to heat a room. If needed, refer to a specialist (industrial and commercial buildings) who will be able to
calculate these heat losses and optimize the required capacity or consult the “Online heating calculation” section of the Stelpro Design Web site
(residential buildings). To heat a large room and to increase your comfort, it is recommended to install several units instead of one. For example,
2 X 1000 W rather than 1 X 2000 W.
If the unit capacity is insufficient for the size of the room, it will be in operation continuously, and may become defective earlier and turn yellow.
Respect distances and positions indicated in the installation section
If the installer or the user modifies the unit, he will be held responsible for any damage resulting from this modification, and the CSA certification
could be void.
This unit must not come into contact with a water source and must be protected from splashes. Do not use it if any part has been immersed.
When mounting the unit, make sure that the anchorage used can support the total weight of the unit with the mounting brackets.
When cutting or drilling into a ceiling, do not damage electrical wiring and other hidden utilities.
When starting up the unit for the first time or after a long period, it is normal that it produces some temporary odours and whitish smoke.
Because this unit is hot when in use, it may pose risks even in normal operation. Therefore, be careful and responsible when using it. To avoid
burns, do not let bare skin touch hot surfaces. The unit must cool down for few minutes since it will stay warm for some time after shut down.
All units require a minimum mounting height of 8 feet (2.44 m) from finished floor. Depending on the model, keep at least 12 or 24 inches away
from any vertical surfaces or walls (see the installation section). However, make sure flammable objects or pieces of furniture do not come into
contact with the unit and keep them at least 24 inches (61 cm) from the unit since they are more flammable than walls and ceilings. Failure to
comply with this warning could lead to a fire. Some materials are more heat-sensitive than others, so make sure those near the unit can withstand
heat.
Never block unit air vents. This obstruction could lead to overheating, which could result in a fire.
Do not insert or allow foreign objects to enter any air vent as this may cause electric shocks, fires, or damages to the unit.
This unit has hot and arcing or sparking parts inside. It is not designed to be used or stored in wet areas or areas containing flammable liquids,
combustible materials or corrosive, abrasive, chemical, explosive and flammable substances such as, but not limited to, gasoline, paint, chlorine,
sawdust and cleaning products. Store it in a dry place when not using it.
Some areas are dustier than others. Thus, it is the user’s responsibility to evaluate if the unit must be cleaned based on the amount of dirt
accumulated on and inside air vents. Accumulated dirt can lead to a component malfunction or discoloration (yellow). It may cause a fire hazard
if not installed and maintained in accordance with these instructions.
The thermal protection activation indicates that the unit has been subjected to abnormal operating conditions. If the thermal protection remains
activated or activates and deactivates repeatedly, it is recommended that a qualified electrician or a certified repair centre examine the unit in
order to make sure it is not damaged. (Refer to the limited warranty)
If the unit is damaged or defective, cut off power supply at circuit breaker/fuse and call a certified repair centre. (Refer to the limited warranty)

INSTALLATION
N.B. Cut off power supply at circuit breaker/fuse before proceeding to the installation.
This unit is designed to be recessed (DRR), installed on the surface of a nished ceiling or suspended from the ceiling (DRI, DRII). All the other parts required
for a suspended installation are not provided with the unit.
All units require a minimum mounting height of 8 feet (2.44 m) from nished oor.
For best results, do not exceed the following recommended mounting heights:
2000 to 5000 watts 10 feet (3.05 m)
7500 to 10 000 watts 12 feet (3.66 m)
Depending on the model, keep at least 12 or 24 inches away from any vertical surfaces or walls (see illustrations below).
DRI and DRII
1. Remove the external cover of the unit and set it aside (4 screws).
2. Remove the mounting bracket (1 or 2 screws and hinges depending on
the model).
3. Screw the mounting bracket to the ceiling and make sure the ceiling structure is strong enough to support the unit. Make sure the mounting bracket
is installed in such a way that the unit will sit straight and level.
4. Remove the wiring compartment cover and set it aside.
5. Hook the slotted side of the internal assembly to the mounting bracket.
Let the unit hang from the bracket.
6. If your model is not equipped with the optional built-in thermostat, a wallmounted thermostat must be installed to control the heater.
7. Run the electrical supply cable up to the wiring compartment of the unit.
Provide a sufcient length of wire to facilitate the connections, which are
made while the unit is still hanging from the bracket.
8. Make the electrical connections using the supplied wire connectors (marrettes). Connect the ground wire to the grounding screw. Make sure all
connections are secure and tight. (For a 2-wire installation, connect the
F and L2 wires to one of the power supply leads and connect the L1 wire
to the other power supply lead. Note that the Fan mode option will not be
available with this type of installation.)
9. Replace the wiring compartment cover. Swing the other half of the interior
assembly into position and screw the assembly to the bracket with the
screw(s) previously removed in step 2.
10. Replace the external cover and screw it into place with the four screws
removed in step 1.
11. Test the unit to make sure it is running properly.

N.B. This product has been designed to be installed into a suspended
ceiling, not into a closed ceiling. Keep in mind that if you intend
on recessing it into a closed ceiling, you will not have access to
it for maintenance and/or repair purposes in the future.
1. Remove the wiring compartment cover and set it aside.
2. Run the electrical supply cable up to the wiring compartment of the unit.
3. Make the electrical connections using the supplied wire connectors (mar-
rettes). Connect the ground wire to the grounding screw. Make sure all
connections are secure and tight. (For a 2-wire installation, connect the
F and L2 wires to one of the power supply leads and connect the L1 wire
to the other power supply lead. Note that the Fan mode option will not be
available with this type of installation.)
4. Replace the wiring compartment cover.
5. If your model is not equipped with the optional built-in thermostat, a wall-
mounted thermostat must be installed to control the heater.
6. This product has been designed to be installed into a suspended ceiling,
therefore there are no mounting brackets supplied with the unit; it must be
supported by the metal framing of the suspended ceiling.
7. Test the unit to make sure it is running properly.
MAINTENANCE
N.B. In order for the warranty to be valid, the unit must be cleaned regularly.
Cut off power supply at circuit breaker/fuse before cleaning the unit. Use a soft rag for dusting. When cleaning, use only a damp rag and non-abrasive dish
soap. Do not use abrasive or chemical cleaners because they may damage the nishing. If the unit is used in a very dusty location, use a vacuum brush to remove dust and other foreign objects from the grilles. Note that cigarette smoke could yellow the discharge grille and that the best way to prevent it is to clean
the unit on a regular basis.
Do not use cleaning products identied with these symbols:
N.B. Note that there is electrical current linked to the unit even if the thermostat is set off. This means that there is a risk of electric shock
as long as the unit is energized.
