IMPORTANT INSTRUCTIONS
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.
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). Use this heater only as described in this
manual. Any other use not recommended by the manufacturer may cause fire, electric shock, or injury to persons. Do not use outdoors.
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 who will be able to calculate these heat losses and optimize the required capacity or consult
the “Online heating calculation” section of the Stelpro website (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.
Do not install the unit where objects or pieces of furniture could be heat damaged.
If the unit’s 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 user modifies the unit, they 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 (e.g. a wet mop). Do not use it if any part has been immersed.
Moreover, do not turn it on or off when standing in water or if your hands are wet.
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 wall, 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. Let the unit cool down for a few minutes before handling it (it stays warm for some time after shut-down). Extreme caution is
necessary when any heater is used by or near children or invalids and whenever the heater is left operating and unattended.
The bottom of this unit must be installed at least 4 inches (10.2 cm) from the floor and 6 inches (15.2 cm) from any adjacent surfaces. However, make sure
objects or pieces of furniture such as, but not limited to, blankets, towels, beds, laundry baskets, clothing, papers, etc. do not come into contact with the unit and
keep them at least 12 inches (30.5 cm) from the unit since they are more flammable than walls and floors. 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.
Do not install on a wall behind a door.
Never block air vents (with objects or other items). You risk damaging the heater and the obstruction could lead to electric shock or 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, a fire 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.
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 give a yellowish colour to unit. Failure to install and maintain unit in accordance
with these instructions poses a fire hasard.
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.)
Before unplugging the unit, all controls must be in the “OFF” position and the current from the main breaker panel should be cut. (The general switch may be
used also, if included.)
If the unit is damaged or defective, discontinue use, cut off power supply at circuit breaker and contact a certified electrician or certified repair centre. (Refer
to the limited warranty)
SAVE THESE INSTRUCTIONS
Note: When a part of the product specification must be changed to improve operability or other functions, priority is given to the product specification itself. In such
instances, the instruction manual may not entirely match all the functions of the actual product. Therefore, the actual product and packaging, as well as the name
and illustration, may differ from the manual.

OPERATION
WITH A BUILT-IN ELECTRONIC THERMOSTAT
HOW TO SET THE TEMPERATURE
You can change the temperature by increasing (top button) or decreasing (bottom button) the set point. The temperature set point will increase
or decrease by increments of 0.5 °C (or 1 °F) each time you press down a button. If you hold down the button, the temperature will quickly scroll
through, allowing a faster and more efficient setting. Once the temperature is set, release the button.
PRECISE ELECTRONIC CONTROL
A chrono-proportional electronic thermostat controls this unit with a high degree of accuracy in order to minimize temperature differences and
increase your comfort level. It allows very stable temperature and ensures uniform comfort. It also keeps the casing at a low temperature, making
it more secure.
The chrono-proportional electronic thermostat entirely regulates the unit by increasing or decreasing the heating cycle percentage according to
the selected temperature. Please note that the unit becomes warmer if the heating demand is higher and that it remains mildly warm when the
demand is lower.
N.B. If the unit is set on high or if it is not functioning at all, the temperature gage of the thermostat sensor cannot
take a precise reading. However, the reading becomes extremely precise once the heating level has stabilized.
Therefore, uniform convection increases the precision of the thermostat.
In order to obtain a precise and optimal ambient temperature reading, the unit must operate on a regular basis, i.e. without significant temperature
variation for at least an hour. (This amount of time increases if a temperature change of more than 4 degrees is requested. Add approximately 15
minutes for every degree above 4).
ELECTRONIC WALL THERMOSTAT CONTROL
An electronic wall thermostat equipped with a proportional tension variation that maintains a precise temperature is preferable thus increasing your comfort level.

OPERATION, MAINTENANCE & TROUBLESHOOTING
ANTIFREEZE PROTECTION
In order to protect your home against freezing and limit energy consumption during long absences, put the thermostat on ANTIFREEZE mode.
To enter this mode, lower the day temperature to between 3°C and 5°C. A Snowflake icon ( ) is displayed. This icon indicates that the economic
and secure ANTIFREEZE mode is on.
THE “NO HEAT” MODE
To turn the heat off, you must lower the temperature to less than 3°C. The inscription “- -” is displayed (note that there is still electrical current to the unit, meaning
that there is a risk of electrical shock).
CELSIUS / FAHRENHEIT MODE
To switch the display from Celsius to Fahrenheit and vice versa, follow the steps listed here:
1.Press and hold the two buttons at the same time.
2.After 3 seconds, °C or °F will flash.
3.Release the buttons to make the change. If the thermostat was in °C, it will now be in°F, and vice versa.
MAINTENANCE
Cut off power supply at circuit breaker/fuse and wait for the unit to cool down before cleaning. Use a soft rag for dusting.
When cleaning, use only a damp rag and non-abrasive dish soap. If you use a cleaning product, always wipe the product off properly to avoid the
discoloration of the unit. Do not use abrasive or chemical cleaners because they may damage the finish. 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 grill and that the best
way to prevent it is to clean the unit on a regular basis.
N.B. There is an electrical current linked to the unit even if the thermostat is set to off. This means that there is a
risk of electric shock as long as the unit is energized.
Do not use cleaning products identified with these symbols:
