This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. Keep combustible materials, like furniture, pillows, bedding, papers, clothes, and curtains at least 36 in. (915 mm) from the front of the heater.
Extreme caution is necessary when any heater is used by or near children or invalids and whenever the heater is left operating and unattended.
Do not operate any heater after it malfunctions. Disconnect power at service panel and have heater inspected by a reputable electrician before reusing.
Do not use outdoors.
Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric shock or fire, or damage the heater.
Do not block air intakes or exhaust in any way whatsoever.
This heater has hot and arcing or sparking parts inside. Do not use it in areas where gasoline, paint, or flammable liquids are used or stored.
Use this heater only as described in this manual. Any other use not recommended by the manufacturer may cause fire, electric shock, or injury.
The heater has been designed and certified for ambient heating only. The maximum ambient operating temperature is 30 °C (86 °F).
The heater is not designed for use in a humid environment where condensation may form on the device.
AMERICAN VERSION ONLY: This heater includes a visual alarm to warn that parts of the heater are getting excessively hot. If the light turns on, immediately turn the heater off and inspect for any objects on or adjacent to the heater that may have blocked the airflow or otherwise caused high temperatures to have occured. If no obstruction is visible, the heater must be checked by a qualified person. DO NOT OPERATE THE HEATER WHEN THE ALARM LIGHT IS ON.
The thermostat should not be considered an infallible device in cases where maintaining a temperature is considered critical. Examples: Hazardous material storage, computer server room, etc. In these particular cases, it is imperative to add a monitoring system to avoid the consequences of a thermostat failure.
