MANTEL ASSEMBLY:
CAUTION: Place a piece of cardboard or protective sheet on the floor in order to avoid
scratching the decorative surface of your mantel during assembly.
Please DO NOT fully tighten the KD screws until all panels are assembled.
NOTE: Each plastic connector is pre-assembled (pre-drilled) on the specific panels with
2 screws. If the KD screw(s) do not fit during assembly, loosen the 2 (pre-drilled) screws to
adjust the plastic connector until the KD screws are able to be installed. Tighten all KD screws
once all panels are assembled.
Step 1: Attach 11 plastic connectors [X] to panels C, E, F, G, H, J and K as shown in
Fig. A (2 pcs KD screws for each plastic connector). Attach panels H and K
together with 4-hole wood connector [S] and 4 KD screws. Attach Panels G and
J together with 4-hole wood connector [S] and 4 KD screws. See Fig A.
Fig. A BACK

Step 2: Attach panel E to panel G and J with 1 KD screw. Attach panel F to panel H and
K with 1 KD screw. See Fig. B.
Fig. B BACK
Step 3: Attach two 4-hole wood connectors [S] to panel E and F with 4 KD screws (2
screws for each wood connector). Attach Panels E, G and J to base panel [B]
with 2 KD screws. Attach Panels F, H and K to base panel [B] with 2 KD screws.
See Fig. C.

Fig. F BACK
Step 7: Tighten all KD screws.
FIREPLACE INSERT INSTALLATION:
The fireplace insert can be installed after the mantel has been fully assembled.
WARNING: MAKE SURE THE FIREPLACE INSERT CONTROLS ARE IN THE OFF
POSITION AND THE UNIT IS NOT PLUGGED IN.
Step 1: Attach two mounting feet [Q] to the fireplace insert (one at each side) with 8
screws for mounting feet [R] (4 screws for each mounting foot). See Fig G.
Fig. G BACK
Step 2: Carefully place the insert in the unit opening. The front of insert should be flush
with the front of the mantel. Carefully lift the insert into the mantel until the top
stopper is against the mantel.
Step 3: Attach 2 mounting clips [U] to the top side of insert with 2 short KD screws [T].
Attach 2 mounting brackets [V] to the feet of insert with 2 KD screws.
See Fig H.
Fig. H BACK
Step 4: Move assembled unit to desired location. Unit should not be positioned in area
exposed to direct sunlight.
WALL ANCHOR SAFETY CABLE
The use of wall anchor safety cable is highly recommended in order to reduce the risk of the
fireplace being tipped over accidentally.
WARNING: THIS CABLE MAY REDUCE POSSIBLE RISK OF INJURY IF THE
FIREPLACE IS IMPROPERLY HANDLED, BUT IS NOT A SUBSTITUTE FOR PROPER
ADULT SUPERVISION. CHILDREN SHOULD NOT BE LEFT UNATTENDED NEAR
ANY HEATER.
1. Drill a 5/16 in (8 mm) hole in the wall. Insert the plastic wall anchor into the hole and gently
tap until the flange on the anchor is against the wall surface.
2. Position the back edge of the mantel close to the wall.
3. Attach the safety cable to the mantel using the screw for mantel. See figure I.
Fig. I BACK
4. Use the screw for wall to attach the other end of safety cable to the wall.
5. Make sure all screws are tight.
OPERATION
After reading complete instructions, confirm all controls on fireplace are in the OFF position.
Plug the fireplace into a 15AMP/120Volt outlet. If the cord does not reach, you may use an
extension cord rated for a minimum of 1875 WATTS. Once the fireplace insert has been
properly connected to a grounded electrical outlet, it is ready to operate.

OPERATION BY THE CONTROL PANEL
The controls are located behind the grill below the front glass and can be accessed by pulling
the grill from the top, forward and down.
WARNING: DO NOT TOUCH HOT SURFACE AT CENTRE OF GRILL, HANDLE, LEFT OR
RIGHT SIDE OF GRILL WHEN PULLING OUT.
ON/OFF: Press this switch for main power and flame effect. The indicator light will turn
on. See below for other control switches.
750W: For low heat function, press this switch while the ON/OFF switch is in the on
position for low heat. The indicator light will turn on.
1500W: For high heat function, press this switch while the ON/OFF switch and the
750W switch are in the on position for high heat. The indicator light will turn on.
TEMPERATURE CONTROL: To adjust the temperature to your individual
requirements, turn the temperature control dial to the right (clockwise) to increase
the desired temperature and to the left for lower temperature. This temperature
control dial can only be used while the ON/OFF, 750W and 1500W switches are in
the ON position.
DIMMER CONTROL KNOB: Turn the dimmer dial clockwise or counter clockwise
to get the desired flame intensity. The dimmer switch can only be used when the
ON/OFF switch is in the on position.
NOTE: When the ON/OFF switch is turned off, all other heater functions will stop even
though the switches may be in the on position.
MAINTENANCE
WARNING:
DISCONNECT POWER AND UNPLUG THE POWER CORD BEFORE ATTEMPTING ANY
MAINTENANCE OR CLEANING TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK OR
