THIS UNIT
COMPLIES WITH
CSA STANDARDS

2INSASSO0518
Before installing and using this product, you must read and
understand these instructions and keep them for future refer-
ence. If the installer and the user do not follow these instruc-
tions, 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 modies the unit, they will be held
responsible for any damage resulting from this modication,
and the CSA certication 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 sucient for normal heating needs. Please
note that the insulation quality of walls and windows are some
of the factors that inuence heat losses, which modify the
required capacity to heat a room. If needed, speak with a spe-
cialist (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 insucient 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 oor. 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 36 in.
(90 cm) from the unit. 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 contain-
ing ammable liquids, combustible materials or corrosive,
abrasive, chemical, explosive and ammable substances such
as, but not limited to, paint, gasoline, chlorine, sawdust and
cleaning products.
RISK OF FIRE, ELECTRIC SHOCK,
BODILY INJURY AND DAMAGE
This product must be installed by a qualied person and con-
nected by a certied electrician, according to the electrical
and building codes eective in your region.
Protect the heating unit with the appropriate circuit breaker or
fuse, in accordance with the nameplate.
Make sure the line voltage (volts) is consistent with that indi-
cated on the unit’s nameplate.
This unit must be grounded.
Switch o the power at the circuit breaker or fuse before
installing, repairing and cleaning the unit.
This unit must not come into contact with a water source
and must be protected from splashes (e.g., splashes from a
sink or shower). Do not use it if any part has been immersed.
Moreover, do not turn it on or o when standing in water or if
your hands are wet.
When starting up the unit for the rst time or after a long pe-
riod, it is normal that it produces some temporary odours.
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.
Do not insert or allow foreign objects to enter any air vent as
this may cause electric shocks, res or damages to the unit.
MAINTENANCE
Some areas are dustier than others. Thus, it is the user’s res-
ponsibility to evaluate if the unit must be cleaned based on
the amount of dirt accumulated on and inside air vents. Ac-
cumulated dirt can lead to a component malfunction or give a
yellowish colour to the unit. Failure to install and maintain the
unit in accordance with these instructions poses a re hasard.
Thermal protection activation indicates that the unit has been
subjected to abnormal operating conditions. If the thermal
protection remains activated it is recommended that a quali-
ed electrician or a certied 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, discontinue use, cut o
power supply at circuit breaker or fuse and have it repaired at
a certied repair centre. (Refer to the limited warranty.)

WARNING: This product must be installed by a certied electrician according to the electrical and building codes
eective in your region.
Install your fan heater in an unobstructed location at least
6 in. o the ground.
TIP: You can access the fan heater’s controls more easily
if you install it 12 in. o 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 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 ammable liquids, combustible
materials or corrosive, abrasive, chemical, explosive
and ammable 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 o.
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 nishing and the
inside of your wall. A 2 × 4 wood stud construction with
a 1/2 in. thick nishing 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 xed to a stud.
• Consider the location of pipes, electrical wires or other
components that may be present inside the wall and
damaged during installation.

ASSO ... T2TW
With its integrated mechanical thermostat and timer
• The temperature setpoint is controlled with the knob with settings from 1 to
5, where 1 represents the minimum amount of heating and 5, the maximum.
• The timer knob lets your fan heater run continuously at maximum heating
mode for a set period (0 to 30 minutes). Ideal for use when taking a shower.

WARNING: Before using your fan heater, make sure that it has been installed by a certied electrician in accor-
dance with the electrical and building codes in your area.
Do not operate without front panel.
MAINTAINING THE FAN HEATER
FOR THE WARRANTY TO BE VALID, THE FAN HEATER’S AIR INLET AND OUTLET MUST BE CLEANED REGULARLY.
WARNING: Cut o the power at the breaker or fuse
before cleaning the unit. High voltage and the risk
of electric shock are present in the unit even if the
thermostat is set to o. Therefore, you can receive an
electrical shock as long as the unit is under power.
Over time, cigarette smoke may cause the outlet grill to yel-
low. The best way to prevent yellowing is to clean the unit
regularly.
Dust the front panel with a soft cloth and clean it with a damp
cloth only. If you use cleaning products, they could cause the
heater to yellow.
If the unit is installed in a very dusty location, use the dust
brush of a vacuum cleaner to remove dust and other foreign
objects.
When maintaining the product, never use:
• A brush or metal scrubbing pad
• Chlorine
• Abrasive cleaning products
• Hydrochloric acid-based products such as bleach
• Any other cleaning products that bear the following
symbols:
