Resetting The Temperature Cutoff Switch
This unit is equipped with a thermostat which controls the
temperature of the room. It does this by turning the heater
on and off. The heater is protected with a safety device
to prevent overheating. Should the heater overheat, an
automatic cut out will turn the heater off and it will not come
back on without being reset. It can be reset by switching
the 3-Position Switch to Off (“ o ”)and waiting ve (5)
minutes before switching the unit back on.
CAUTION: If you need to continuously reset the heater,
unplug the unit and call Technical Support at
1-888-346-7539. Please have your model and serial
number ready when calling.

Maintenance
WARNING: Disconnect power before attempting any
maintenance or cleaning to reduce the risk of re, electric
shock or damage to persons.
Light Bulb Replacement
Allow at least ve (5) minutes for the light bulbs to cool
before touching them to avoid accidental burning of the skin.
The light bulbs need to be replaced when you notice a dark
section of the ame or when the clarity and detail of the
log ember bed exterior reduces. There are three (3) bulbs
under the Log Set Assembly, which generate the ames
and embers, and two (2) bulbs above that illuminate the log
exterior.
Lower Light Bulb Requirements: Quantity of three (3) clear
chandelier or candelabra bulbs with an E-12 (small) socket
base, 60 Watt rating. Example: GE 60BC or Philips 60CTC.
Do not exceed 60 Watts per bulb.
Helpful Hints: It is a good idea to replace all light bulbs at
one time if they are close to the end of their rated life. Group
replacement will reduce the number of times you need to
open the unit to replace light bulbs. Care must be taken
when removing the Log set assembly as it contains LED’s
and wires (DF2608 only).
