OS2527GB BTU Free Standing Electric Stove
Product Information
The product is an electric firebox cassette with a model number of OS2527GB and a part number of 6909560100. The service manual provides important safety information that must be read before attempting to service the cassette. It is important to comply with all warnings and safety instructions contained in the manual to prevent personal injury or property damage. The cassette should only be repaired by a qualified technician or service agency.
The operation of the cassette is controlled by a remote control that includes a flame button, standby button, and heat button. The cassette includes a thermostat control that allows the temperature to be adjusted to individual requirements. The mode selector switch turns on the flame effect, while the flame intensity control adjusts the intensity of the flame and smoke effect.
The cassette also includes a water tank that needs to be refilled when empty. If the heater overheats, an automatic cut out will turn the heater off, and it can be reset by switching the On/Off Switch to Off and waiting for 10 minutes before switching the unit back on. If continuous resetting is required, it is recommended to call Dimplex North America Limited for technical support.
Product Usage Instructions
-
Read the service manual before attempting to service the cassette to ensure compliance with all warnings and safety instructions.
-
Use a qualified technician or service agency to repair the cassette.
-
Properly install the electric firebox before use.
-
Ensure that the appliance is in a level position.
-
Use the remote control to operate the cassette.
-
To adjust the temperature, turn the thermostat control clockwise all the way to turn on the heater. When the room reaches the desired temperature, turn the thermostat knob counter-clockwise until you hear a click. Leave thermostat in this position to maintain the room temperature at this setting. For additional heat, turn clockwise until you hear the click again and the heater will turn on.
-
To turn on the flame effect, press the mode selector switch once. This will be indicated by an audible beep. Although the lights turn on immediately it will take 30 seconds before the flame effect starts.
-
To adjust the intensity of the flame and smoke effect, use the flame intensity control. Turning the control knob clockwise decreases the intensity of the flame and smoke effect. Turning the control counterclockwise will increase the flame and smoke effect.
Give the flame generator some time to react to changes made on the flame control knob. -
Refill the water tank when it is empty. See instructions under Maintenance Section for refilling tank. When this procedure is complete, the main lamps will illuminate, but it will take 30 seconds before the flames return.
-
If the heater overheats, switch the On/Off Switch to Off and wait for 10 minutes before switching the unit back on to reset it. If continuous resetting is required, call Dimplex North America Limited for technical support.
Always use a qualified technician or service agency to repair this cassette.
NOTE: Procedures and techniques that are considered important enough to
emphasize.
CAUTION: Procedures and techniques which, if not carefully followed, will
result in damage to the equipment.
WARNING: Procedures and techniques which, if not carefully followed, will
expose the user to the risk of fire, serious injury, or death.
OPERATION
WARNING: This electric firebox must be properly in-stalled before it is used.
NOTE: When the unit is used in an environment where background noise is
very low, it may be possible to hear a sound which is related to the operation
