Important Instructions

Before installing and using this product, read and understand these instructions. Keep them for future reference. Failure to follow these instructions may void the warranty and relieve the manufacturer of liability. Adhere to the following instructions to avoid personal injury, property damage, serious injury, or potentially fatal electric shocks.

Modifications by the installer or user will hold them responsible for any resulting damage and may void CSA certification.

Intended Use

For indoor installation only. Ensure the unit is appropriate for its intended use. Refer to the product catalog or a representative if needed.

Recommended Heating Capacity: 1.25 W per ft³ (0.03 m³), equivalent to 10 W per ft² (0.09 m²) for an 8 ft (2.44 m) ceiling. Factors like wall and window insulation affect required capacity. Consult a specialist or the "Calculation Tools/Heating Calculator" on the Stelpro Design website for precise calculations. Insufficient capacity may lead to continuous operation and premature yellowing.

Position

Do not install the unit where objects or furniture could be damaged by heat. Maintain minimum clearances: 6 inches (15 cm) from adjacent surfaces and 6 inches (15 cm) from the floor. Keep combustible materials (furniture, bedding, papers, clothes, curtains) at least 36 inches (90 cm) from the front of the heater and away from the sides and rear. Ensure nearby materials can withstand heat. Do not install on a wall behind a door. Avoid placing the heater where it could impede the opening of nearby furniture drawers or doors.

This unit contains hot and arcing/sparking parts. It is not designed for wet areas or areas with flammable liquids, combustible materials, or corrosive, abrasive, chemical, explosive, or flammable substances (e.g., paint, gasoline, chlorine, sawdust, cleaning products).

Risk of Fire, Electric Shock, Bodily Injury, and Damage

Installation must be performed by a qualified person and connected by a certified electrician according to local codes. Protect the unit with an appropriate circuit breaker or fuse. Ensure line voltage matches the unit's nameplate. The unit must be grounded. Switch off power at the circuit breaker before installation, repair, or cleaning. Keep the unit away from water sources and protected from splashes. Do not use if any part has been immersed, or operate with wet hands or while standing in water.

Temporary odors are normal upon first use or after long periods of inactivity. The unit surfaces become hot during operation; avoid direct skin contact to prevent burns. Allow the unit to cool before touching after shutdown.

Exercise extreme caution when children or invalids are present or when the heater is left unattended. Do not insert foreign objects into ventilation openings to prevent electric shock, fire, or damage.

Maintenance

Do not block air intakes or exhaust to prevent fire. Users are responsible for cleaning dust accumulation from air vents, which can cause malfunction or discoloration. Failure to maintain the unit poses a fire hazard.

Thermal protection activation indicates abnormal operating conditions. If it persists, have the unit examined by a qualified electrician or certified repair center. If the unit is damaged or defective, discontinue use, cut off power, and have it repaired by a certified center.

Using and Maintaining the Fan Heater

Warning: Ensure installation by a certified electrician according to local codes. Do not operate without the front panel.

Controlling the Fan Heater

Control methods vary by model:

Maintaining the Fan Heater

For warranty validity, the fan heater's air inlet and outlet must be cleaned regularly.

Warning: Disconnect power at the breaker or fuse before cleaning. High voltage is present even when the thermostat is off.

Over time, cigarette smoke may yellow the outlet grill. Regular cleaning prevents this. Dust the front panel with a soft cloth and clean with a damp cloth only. Avoid cleaning products that may cause yellowing.

In dusty locations, use a vacuum cleaner's dust brush to remove debris. Never use a brush or metal scrubbing pad, chlorine, abrasive cleaning products, hydrochloric acid-based products (like bleach), or cleaning products bearing warning symbols [three triangular symbols with exclamation marks].

Troubleshooting the Fan Heater

The following table outlines common issues and alerts. If your problem is not listed or the solution doesn't work, turn off power and contact customer service.

Restarting the Fan Heater After Thermal Protection is Triggered

In case of overheating, thermal protection switches off heating but keeps ventilation running (ventilation without heat). To resume normal operation:

1. Identify and eliminate the cause of overheating (e.g., ensure air inlets/outlets are unobstructed and clean).
2. Verify the fan heater has not suffered heat damage.
3. Switch off the power supply from the electrical panel.
4. Wait ten minutes, then turn the power back on.

If heating does not resume, an internal component may be defective or an additional thermal protection device may have been triggered. Contact STELPRO's customer service department.
