! NOTE: If the power cord needs replacing or if the unit
needs to be removed from the wall for any other reason please begin service by following the “PREPARATION FOR SERVICE” instructions, then move on to the section “INSTRUCTIONS FOR REMOVING FROM WALL”.
Tools Required: Philips head screwdriver
WARNING: Disconnect power before attempting any maintenance or cleaning to reduce the risk of electric shock or damage to persons.
CAUTION: If unit was operating prior to servicing allow at least 10 minutes for lights and heating elements to cool off to avoid accidental burning of skin.
1. Disconnect power source.
· Unplug the fireplace from the outlet.
· If unit has been hardwired for power or outlet is not accessible from the front, turn the breaker off at the electrical panel.
2. Remove the front glass assembly by removing the 2 screws (1 on the left and 1 on the right side, located just inside the top front vent opening). These screws secure the front glass panel to the inside of the fireplace. (Figure 4)
3. Lift the front glass assembly off of the 4 mounts located between the outer and inner casing of the fireplace: 2 on the left and 2 on the right. (Figure 3) Carefully place the glass assembly aside in a safe location.
4. Remove the decorative glass ember-bed pieces from the media tray, which lies along the bottom of the interior Partially Reflective Glass. A medium sized container such as a bucket or a box will be needed to keep the glass ember-bed pieces together.
5. Remove the Partially Reflective Glass by removing the 2 screws on each bracket; (2-brackets in total), located on the left and right side of the Partially Reflective Glass.
6. With one hand gently supporting the Partially Reflective Glass, carefully pry the Partially Reflective Glass forward from the upper half so that it begins to tilt forward from the top. Grasp the Partially Reflective Glass from the sides and carefully lift it up and out from the front of the fireplace. Set it aside in a safe place.
