as a television, a mantel, or artwork, always follow the
recommendations provided by its manufacturer for
installation over a heater.
Figure 2 provides the overhang clearance
recommendations for the fireplace. Areas above the
fireplace are marked as follows:
•Solid gray box ( ) is subject to temperatures greater
than 65°C (149° F).

Installation Instructions
!NOTE: Two people are required for installation.
1. Prepare a wall with a framed opening, following the dimensions shown in Figure 3. The replace can either be
installed partially-recessed (2x4 frame) or ush-mounted (2x6 frame).
CAUTION: Decorative nishing material (such as brick) should be limited to ½" (13 mm) overhang to ensure
adequate ow of heated air out of the rebox area.
CAUTION: This replace is NOT load-bearing. Ensure the opening for the replace is framed in such a way that
the weight of the building materials will not create pressure on the top of the replace.
!NOTE: For 2"x4" construction where the unit will be partially recessed, it is recommended to use XLFTRIM kit
(sold separately) to accomodate the protruing portion of the replace.

Media Arrangement
For best results when using the supplied media, arrange
as follows:
1. Evenly space the large media in the media tray along
the back of the media tray
2. Pour and evenly distribute the smaller crystals into the

3. If using the optional driftwood and river rock kit,
evenly disperse the river rocks and place the
driftwood pieces on top.
It is possible to use custom media ornaments to decorate
your rebox. The custom media must t easily without
scratching the glass or bowing the media bed, and must
not be composed of sand or liquid, which could interfere
with the safety of the rebox.

General Operation
WARNING: This electric rebox must be properly installed before it is used.
This rebox operates with Comfort$averTM technology, which automatically adjusts the fan speed and heater wattage
to safely and precisely match the requirements of the room based on the thermostat setting. The heater operates
such that once the room reaches the set point, the fan and heater will continuously run at a low level, to maintain the
desired room temperature. If the temperature in the room rises signicantly, the heater will turn off and periodically
turn back on to circulate the air around the unit, until the room temperature drops and requires the heater to be
on again.
!NOTE: The element retains heat after shutdown. When the heat is turned off, there is a 2-minute cool down period
before the fan shuts off completely.
!NOTE: The replace will retain the previously used settings after a power interruption.
Hidden Touch Controls
The hidden touch controls are located on the upper right of the replace. (Figure15)
Remote Operation
The replace is supplied with a multifunction IR remote control. (Figure16)
!NOTE: To operate correctly, the remote control must be pointed toward the front of the unit.

3. Close the battery cover.
The battery must be recycled or disposed of properly. Check with your Local Authority or Retailer for recycling
advice in your area.
Cleaning
Mirrored Glass Cleaning
The mirrored glass is cleaned in the factory during the assembly operation. During shipment, installation, handling,
etc., the mirrored glass may collect dust particles; these can be removed by dusting lightly with a clean dry cloth.
To remove ngerprints or other marks, the mirrored glass can be cleaned with a damp cloth. The mirrored glass
should be completely dried with a lint-free cloth to prevent water spots. To prevent scratching, do not use abrasive
cleaners.
Fireplace Surface Cleaning
Use only a damp cloth to clean painted surfaces of the fireplace. Do not use abrasive cleaners.
The replace should not be operated with an accumulation of dust or dirt on or in the unit, 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 a minimum yearly intervals.
Servicing
Except for installation and cleaning described in this manual, an authorized service representative should perform
any other servicing.
Maintenance
WARNING: Disconnect power and allow heater to cool before attempting any maintenance or cleaning to
reduce the risk of re, electric shock or damage to persons.
