5. Do not use outdoors.
6. To disconnect the unit, turn the controls off, and then
switch off at main power supply panel.
7. Do not insert or allow foreign objects to enter any ventilation or exhaust opening as this may cause an electric
shock or re, or damage to the heater.
8. To prevent a possible re, do not block air intake or ex-
haust in any manner.

parts inside. Do not use in areas where gasoline, paint,
or ammable liquids are used or stored.
10. Do not modify this heater. Use it only as described in
this manual. Any other use not recommended by the
manufacturer may cause re, electric shock or injury to
persons.

in tamperproof single or double pole thermostat kit.
Dimplex kickspace heaters are designed and tested for safe
and trouble-free operation. All Dimplex kickspace heaters are
protected against overheating by a built-in thermal cutout.
Free airow throughout the heater is extremely important for
the most efcient operation of the heater. Restricted airow
may cause the thermal overload protector to cycle the heater
“ON and OFF”. A cycling heater will not supply sufcient heat
to the room.
Avoid direct contact of paper, fabric, or furniture with heater.
