IMPORTANT INSTRUCTIONS

Before installing and using this product, you must read and understand these instructions and keep them for future reference. If the installer and the user do not follow these instructions, the manufacturer cannot be held liable in any way and the warranty will be null and void.
The following instructions must be adhered to in order to avoid personal injuries or property damages, serious injuries, and potentially fatal electric shocks.
If the installer or the user modifies the unit, they will be held responsible for any damage resulting from this modification, and the CSA certification could be void.

INTENDED USE
For indoor installation only.
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 per ft³(0.03 m³). This corresponds to 10 W per ft² (0.09 m²) based on a standard ceiling height of 8 ft (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, speak with a specialist (industrial and commercial buildings) who will be able to calculate these heat losses and optimize the required capacity or consult the “Calculation
Tools/Heating Calculator” section of the °STELPRO Design website.
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.

POSITION

Do not install the unit where objects or pieces of furniture could be heat damaged.
Respect the following distances and positions: This unit must be installed at least 6 in. (15 cm) from any adjacent surfaces and at least 6 in. (15 cm) from the floor. Keep combustible materials, such as furniture, pillows, bedding, papers, clothes, etc., and curtains at least 36 in. (90 cm) from the front of the heater and keep them away from the sides and rear. 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.
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, paint, gasoline, chlorine, sawdust, and cleaning products.

WHERE TO INSTALL YOUR FAN HEATER

Install your fan heater in an unobstructed location at least 6 in. off the ground.
TIP: You can access the fan heater’s controls more easily if you install it 12 in. off the ground.
ATTENTION: To avoid any risk of overheating, leave a clearance of at least 36 in. in front of the fan heater and 6 in. on either side of it.
No objects or furniture such as, but not limited to, blankets, towels, a bed, a laundry basket, clothing, papers, etc., should come into contact with the fan heater. Keep these items at least 36 in. away from it.
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, paint, gasoline, chlorine, sawdust, and cleaning products.

Make sure that objects or furniture near the heater can withstand the heat it gives off.
Do not install the heater on a wall behind a door.  If a piece of furniture is nearby, make sure the fan heater will not impede the opening of its drawers or doors.
To recess your fan heater in a wall, consider the following:

• Check the construction of your wall. There should be at least 4 in. from the outside of your finishing and the inside of your wall. A 2 × 4 wood stud construction with a 1/2 in. thick finishing are considered compliant [A].
• Avoid installing in an exterior wall as this decreases the wall’s insulation.
• Consider the location of the studs in your wall. One side of the heater must be fixed to a stud.

Consider the location of pipes, electrical wires, or other components

that may be present inside the wall and damaged during installation.
CUTTING THE POWER supply

To protect yourself from the risk of electric shock, turn off the power to the lead wires from the electrical panel.
