For further information or to consult this guide on line, please visit our Web site.

This unit complies with

the CSA and UL standards

INSRUH1108

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.

Do not install the unit where objects or pieces of furniture could be heat damaged.

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 such as, but not limited to, showers, bathtubs, sinks, toilets, etc. 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 wall or 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.

This unit must be installed at least 4 inches (10 cm) from the walls and between 6’ (183 cm) from the floor. However, make sure objects

or pieces of furniture do not come into contact with the unit and keep them at least 12 inches (30 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.

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.

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 and call a certified repair centre. (Refer to the limited warranty)

WARNING WARNING WARNING WARNING

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.

INSTALLATION

N.B. Cut off power supply at circuit breaker/fuse before proceeding to the installation.

This unit must be installed at no less than 4” (10 cm) from adjacent walls and 6’ (183 cm) from the floor.

• Avoid directing the airflow from the unit heater towards occupants of the

room, beams, poles, machinery and/or against the walls. Instead, try to

direct the airflow along the wall, preferably an exterior wall that is exposed

to the wind.

• When using a wall-mounted thermostat, install the thermostat on an

interior wall or beam, away from cold airflow, internal heat sources or the

hot air discharge coming directly from the unit heater itself. Insulate the

thermostat when installed on a steel beam.

• Smaller rooms will generally require only one unit heater. For larger rooms,

install several unit heaters in such a way that will promote a peripheral air

circulation, as demonstrated on the illustrations hereof.

ELECTRICAL CONNECTION

The ground fault protection connection must be made by connecting the green wire coming from the circuit breaker panel to the green

screw located inside the junction box of the heater.

N.B. All electrical connections must be made by a qualified electrician, according to the electrical and building codes

effective in your region.

OPERATION

This heater must be controlled with a 240-volt thermostat (thermostat not included) or a built-in thermostat: temperature setting

ranges from 10°C to 44°C (55°F to 110°F), not indicated by the thermostat knob.

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 this heater. 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 finishing. 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 identified 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.

This warranty is exclusive and in lieu of all other representations and warranties (except of title), expressed or implied, and Stelpro expressly

disclaims and excludes any implied warranty of merchantability or implied warranty of fitness for a particular purpose.

Stelpro’s liability with respect to products is limited as provided above. Stelpro shall not be subject to any other obligations or liabilities what-

soever, whether based on contract, tort or other theories of law, with respect to goods or services furnished by it, or any undertakings, acts

or omissions relating thereto. Without limiting the generality of the foregoing, Stelpro expressly disclaims any liability for property or personal
