Operation

Electric Fireplace Manual Control

The manual controls for the replace are located behind the control panel on the front of the replace (Figure 1). A switch

is in the ON position when the side with the markings on

(i.e. I, or II) is pushed in.

Figure 1

Control Panel

Manual Control

A - Main On/Off Switch

Controls the electricity supply to the heater and ame effect. Pressing in the ( I ) side will turn the replace on, pressing the ( O ) side in will turn the replace off.

Switches

NOTE: If Switches B and C are in the off position, only

the ame effect will turn on when Switch A is activated.

Resetting The Temperature Cutoff Switch

Should the replace 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 Switch A (Figure 1 A) to OFF 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 Dimplex North America Limited at 1-888-346-7539 for technical support.

NOTE: This switch must be in the ON (I) position for

heater to operate with or without heat.

B - Low Heat Switch

(I) Provides 715 Watt heat output.

C - High Heat Switch

(II) Provides 1430 Watt heat output with Switch B.

Light Bulb Replacement

(2)

Mirror Replacement

Allow at least ve (5) minutes for light bulbs to cool before

touching bulbs to avoid accidental burning of skin.

Light bulbs need to be replaced when you notice a dark

section of the ame. There are two (2) bulbs behind the log set which generate the ames and embers.

Disconnect power before attempting any maintenance or cleaning to reduce the risk of electric shock or damage to persons.

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.

Lower Light Bulb Requirements

Quantity of two (2) clear chandelier or candelabra bulbs with an E-12 (small) socket base, 60 Watt rating.

Do not exceed 60 Watts per bulb

To access the light bulb area (Figure 2):

1. Remove the four (4) silver Phillips screws on the Access Panel at the rear of the replace and remove panel.

If the replace was operating prior to servicing allow at least ve (5) minutes for light bulbs and heating element to cool off

to avoid accidental burning of skin.

Disconnect power before attempting any maintenance or cleaning to reduce the risk of electric shock or damage to persons.

Replacement Procedure

1. Pull replace away from the wall far enough to access

the back of the unit.

2. Remove two (2) Phillips screws from each of the four (4) brackets which attach the replace to the mantel (Figure 3).

3. Carefully push replace out the front of the mantel to remove (Figure 4).

Figure 3

2. Examine the bulbs to determine which bulbs require replacement.

3. Hold the socket while unscrewing the bulb.

4. Hold the socket while screwing in the new bulb.

5. Reattach Access Panel with screws removed in step 1.
