OF FIRE, ELECTRIC SHOCK, AND INJURY TO PERSONS, 

INCLUDING THE FOLLOWING: 
1.  Read all instructions before installing or using this heater.
2.    This heater is hot when in use. To avoid burns, do not let bare 

skin touch hot surfaces. Keep combustible materials, such as 

furniture, pillows, bedding papers, clothes, etc. and curtains 

at least 3 feet (0.9 m) from the front of the heater.

3.    Extreme caution is necessary when any heater is used by 

or near children or invalids and whenever the heater is left 

operating and unattended. 

4.    Do not operate any heater after it malfunctions. Disconnect 

power at service panel and have heater inspected by a 

reputable electrician before using. 

5.   Do not use outdoors.
6.    To disconnect heater, turn controls to off, and turn power to 

heater circuit at main disconnect panel. 

7.    Do not insert or allow foreign objects to enter any ventilation 

or exhaust opening as this may cause an electric shock, fire 

or damage to the heater. 

8.    To prevent a possible fire, do not block air intake or exhaust 

in any manner. 

9.   A 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. 

10.   Use this heater only as described in this manual. Any other 

use not recommended by the manufacturer may cause fire, 

electric shock, or injury to persons. 

11.   This heater is provided with automatic resetting thermal limit 

and an alarm beeper to alert user if heater has overheated. 

If the alarm has activated, immediately turn off the heater 

and inspect and remove any objects around heater that may 

have blocked the airflow or otherwise caused the heater 

to overheat. Do not continue to use heater if it repeatedly 

overheats and activates the alarm.

 

 CAUTION - On FFCH.R models, once heater has cycled off 

on the thermal limit, the heater will not return to operation until 

the user restarts and reprograms the control.  Therefore, this 

unit is not recommended for freeze protection applications.

not intended for use in special environments. Do not use 

damp or wet locations such as marine or greenhouse or in 

areas where corrosive or chemical agents are present.

additional warnings and precautions. 

14.   For safe and efficient operation, and to extend the life of 

your heater, keep your heater clean - See MAINTENANCE
