sawdust, etc.) from interior and exterior of heater.
Dimplex heaters are designed and tested for safe and trouble-free operation. All Dimplex 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.

CAUTION: Before removing the front cover for cleaning,
make certain the power has been turned off at the circuit
breaker panel.
CAUTION: Allow adequate time for the element and body
casing to cool before attempting to work on the heater.
The FFIH series contain no moving parts. Since the
appliance contains no moving parts little maintenance is
required beyond vacuum cleaning. It is however essential
that the heater is not operated with an accumulation of dust
or dirt on the element, as this can cause a build up of heat
and eventual damage. For this reason the heater must be
inspected regularly, depending upon conditions and at least
at yearly intervals. Once cleaning is complete replace the
front cover and restore power.
WARNING: The user can perform cleaning ONLY. All
other servicing should be performed by qualied service
personnel.
