Maintenance
Glass Cleaning
WARNING: Disconnect power before attempting any
maintenance or cleaning to reduce the risk of fire,
electric shock or damage to persons.
Light Bulb Replacement
Allow at least five (5) minutes for light bulbs and heater to
cool off before touching bulbs to avoid accidental burning of
skin.
Light bulbs need to be replaced when you notice a dark
section of the flame or when the clarity and detail of the log
exterior disappears. There are two (2) bulbs under the log
set which generate the flames and embers.
Tool requirements: Phillips screwdriver.
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.
The front glass is cleaned in the factory during the
assembly operation. During shipment, installation,
handling, etc., the front glass may collect dust particles,
these can be removed by dusting lightly with a clean dry
cloth.
To remove fingerprints or other marks, the glass can be
cleaned with a damp cloth. The glass should be completely dried with a lint free cloth to prevent water spots. To
prevent scratching, do not use abrasive cleaners or spray
liquids on the glass surface.
Surface Cleaning
To remove fingerprints or other marks, the exterior finish
can be cleaned with a damp cloth with a mild detergent.
The surface should be completely dried with a lint free cloth
to prevent water spots.
To prevent scratching, do not use abrasive cleaners or
spray liquids on any surface.

PREPARATION FOR SERVICE
Tools Required: Philips head screwdrivers
-Large and Medium Head
Needle nose pliers.
WARNING: If the fireplace was operating prior to servicing, allow at least 10 minutes for light bulbs and heating
elements to cool off to avoid accidental burning of skin.
WARNING: Disconnect power before attempting any
maintenance to reduce the risk of electric shock or damage
to persons.
1. Stabilizing straps may have been installed attaching
this corner fitting cabinet to the wall on the left and right
back/corner panels. If so, remove them first by removing the screw anchoring them to the wall.
2. Pull the cabinet away from the wall.
3. Unplug the fireplace from the outlet.
4. On the (2) backside, corner-fitting panels of the exterior
cabinet, release the 4 “CAM LOCKS”, (2) on the left
and (2) on the right near the top. This is done by using
a large Philips head screwdriver and turning the each
cam lock ¼ turn counter-clockwise until the “—” and “+”
symbols line up horizontally.
5. With cam locks released, carefully lift the top panel off
the cabinet. The top panel will have long metal shafts
attached to it, which are part of the interior cam lock
mechanism. Be careful not to break these off.
6. Lay the cabinet down on the floor or your work surface,
onto the back/corner panel with the switches closest to
the floor.
! NOTE: If the surface you are using as a work area on
is a finished surface that is prone to scratches (i.e. hardwood flooring), it is recommended that a protective barrier
be used underneath, (i.e. cloth, cardboard, thick plastic).
7. Remove the decorative metallic grill on the front of the
cabinet, which covers the heat area of the fireplace.
This is magnetically attached and can be remove by
pulling it away starting in one of the corners or grasping
it at the grill openings.
8. Remove the (2) brackets found inside the body of the
cabinet that attach the firebox-insert to the interior of
the cabinet. There are (2) Philips screws in each of the
(2) brackets.
9. Slide the firebox out from the top opening of the cabinet.
10. Remove the (1) Philips screw located on the lower
housing back panel below the power cord.
11. Remove 6 screws in total from the “bottom” heaterhousing panel, (2) on the bottom left edge, (2) on the
bottom right edge, and (2) on the front face of the housing panel, just above the heat vent. Once screws are
removed from the left panel, you will have to turn the
firebox ¼ turn so that it rests on the right back panel
with the switches being farthest away from the floor.
12. Once these screws are removed, pull off the bottom
heater-housing panel and rest it just in front of the
fireplace.
! NOTE: Wires inside the heater housing are attached to
the panels with mountable wire ties so the panel cannot be
moved very far.
13. Release the mountable wire-ties from the heater-housing panel by using needle nose pliers to squeeze the
wire-tie tab ends from the exterior side of the panels.
Squeeze the tabs enough to reduce the spread of the
tabs and push it through the hole on the panel. While
squeezing these tabs, gently pull on the wire tie from
inside the panel, (opposite side) until it comes through.
This will free up the wires and allow more room to access parts.
! NOTE: These wire ties will be re-inserted when service
is complete therefore they should not be cut off unless you
have the same type of replacement ties.
14. Proceed to the next instructions in the manual relating
to the repair being performed.
LIGHT HARNESS REPLACEMENT

where it meets the side:
a. (2) screws on the bottom near the back left,
b. (2) screws on the bottom near the back right,
c. (2) screws on the bottom near the center front of
this middle panel.
3. Carefully pull this panel down as long as the length of
the wires will allow. The wires are secured by wire ties
to this panel and do not allow much space for access.
4. Through the slight gap between the upper housing
panel and the upper cavity of the firebox, use needle
nose pliers to release all of the wire-ties from the lower
panels by squeezing the wire-tie tab ends from the
outside of the panels. See order of releasing wire tabs
below.
5. With the needle nose pliers, squeeze the wire tie tabs
enough to reduce the spread of the tabs and push it
through the hole on the panel. While squeezing these
tabs, gently pull on the wire and tie from the opposite
side of the panel until it comes free. This will free up
the wires so you can re-position the panels in a way to
allow more room for parts access.
6. ! NOTE: These wire ties will be re-inserted when
service is complete therefore should not be cut off unless you have the same type of replacement ties.
7. Release wire tie mounting tabs in the following order:
a. Start with the wire ties below the remote control
7
receiver on the back left side panel.
b. Proceed to the wire ties along the upper housing
panel above the receiver, (below the flicker rod) and
work your way from left to right.
c. The last tab to be released will be right below the
light bulb on the right.
8. Pull this upper panel farther down as much as you can
it to allow access to the light sockets and wire harness
from the back.
9. Remove the (2) wire nuts on the interior side of the
panel that connect the light harness wires to their
power source.
! NOTE: Both light harness wires are black. Take note
of which wires are secured with which wire nut. The ribbed
black wire is the “Neutral” and goes with the group of neutral white wires, which are connected with one wire nut).
The smooth black wire from the light harness is the “Load”
“L1” wire, and is grouped with another black and a red wire
in the other wire nut.
10. Remove the light bulbs located on the socket mounting
bracket, behind the upper-housing panel by unscrewing
them counter-clockwise.
11. Remove the sockets by turning the socket rings counter
clockwise; then pushing each socket out of the mounting bracket.
12. Light harness wires are fed through an opening below
the bracket to the wire nuts on the interior of the housing. Pull the light harness wires out from this opening
and feed the wires from the new light harness through
this opening. Reconnect each wire to the appropriate
wire nuts as mentioned in the “NOTE” above in step 9.
13. Unscrew rings from the new sockets. Position the
new sockets into the correct openings on the mounting
bracket and secure the sockets into place by turning
the rings clockwise onto the thread on each socket.
14. Push all of the mountable wire ties back into the correct holes on the housing panels making sure they are
secure. You will have to move the panel up closer into
the upper cavity. This will greatly reduce the amount
of lead or give in the wires and the workspace, on the
unit.
! NOTE: If the wire ties are not securing properly, use a
flat instrument to slightly spread the tabs farther apart and
then re-insert into the appropriate holes in the panel.
15. Re-assemble the firebox in reverse order, taking care
that the wires are guided through the cutout openings
on the left and right of the housing panels and no wires
are touching the heater assembly blower/fan once reassembled.

b. Proceed to the wire ties along the upper housing
panel above the receiver, (below the flicker rod) and
work your way from left to right.
c. The last tab to be released will be right below the
light bulb on the right.
7. Pull this upper panel farther down as much as you can
and reposition it to allow access to the switch housing
above this panel on the top right hand side.
8. Locate the thermostat control dial on the left hand side
on the front of the fireplace and pull it forward, off the
shaft of the thermostat control.
9. Remove the 2 screws that fasten the thermostat control
to the front panel. These screws require a small head
on a Philips screwdriver.
10. Carefully guide the thermostat down and out through
the opening underneath the thermostat housing.
11. Disconnect the 2 wires from the thermostat, noting their
original location and reconnect onto the new thermo-

stat.
12. Re-position the new thermostat back into the original
opening and re-attach the thermostat to the front panel
using the two original small screws.
13. Align the thermostat dial in the correct position and
push it back onto the shaft of the thermostat control.
14. Push all of the mountable wire ties back into the correct holes on the housing panels making sure they are
secure. You will have to move the panel up closer into
the upper cavity. This will greatly reduce the amount
of lead or give in the wires and the workspace, on the
unit.
! NOTE: If the wire ties are not securing properly, use a
flat instrument to slightly spread the tabs farther apart and
then re-insert into the appropriate holes in the panel.
15. Re-assemble the firebox and cabinet in reverse order,
taking care that the wires are guided through the cutout
openings on the left and right of the housing panels
and no wires are touching the heater assembly blower/
fan once re-assembled.
REMOTE CONTROL RECEIVER
REPLACEMENT
Tools Required: Philips head screwdriver
Needle nose pliers
CAUTION: Follow “Preparation for Service” instructions
before proceeding.
! NOTE: Step 14 (releasing of wire ties on back panel)
may not be required. Use your own discretion.
1. Locate the remote receiver mounted on the back left
panel of the middle housing cover.
2. Remove the 3 wires from the receiver noting their original location.
3. Remove the remote control receiver noting it’s orientation on the panel. Using a pair of needle nose pliers,
squeeze the ends of the 4 “stand-off” mounting tabs
enough to reduce the spread of the tabs and push
them through the mounting hole on the receiver board.
While squeezing these tabs, gently pull the board away
from the back panel until it comes free.
! NOTE: These “standoffs” will be re-inserted onto the
new board therefore should not be cut off unless you have
the same type of replacement connectors.
4. Align the new receiver board mounting holes with the
“standoffs” in the original orientation, and push the new
remote control receiver onto the “standoffs” making
sure the board is secure. If the “stand-off” mounting
tabs are not securing properly, it is likely from originally
squeezing them with the pliers during removal. Use
a flat instrument to just slightly spread the tabs farther
apart.
5. Reconnect the 3 wires onto the receiver board.
! NOTE: Wire colors may vary from the original following
description.
- Orange from “ON/OFF” switch onto JP1 – “L” on
the board.
- Tan (darker orange/red) from “Heater” switch onto
JP2 on the board
- White from group of neutrals with a wire nut onto
JP3 on the board.
6. Re-assemble the firebox and cabinet in reverse order,
taking care that the wires above on the left and right of
the housing panels are touching the heater assembly
blower/fan once re-assembled.
POWER CORD REPLACEMENT
Tools required: Phillips head screw driver.
Needle nosed pliers.
CAUTION: Follow “Preparation for Service” instructions
before proceeding.
1. Remove the 6 screws that hold the “upper” heaterhousing panel located on the panel, above the remote
control receiver.
2. These screws are along the edge of this upper panel
where it meets the side:
a. (2) screws on the bottom near the back left,
b. (2) screws on the bottom near the back right,
c. (2) screws on the bottom near the center front of
this middle panel.
3. Carefully pull this panel down as long as the length of
the wires will allow. There won’t be much space because of the wire ties attached to the panel.
4. Through the slight gap between the upper housing
panel and the upper cavity of the firebox, use needle
nose pliers to release all of the wire-ties from the lower
panels by squeezing the wire-tie tab ends from the
outside of the panels. See order of releasing wire tabs
below.
5. With the needle nose pliers, squeeze the wire tie tabs
enough to reduce the spread of the tabs and push it
through the hole on the panel. While squeezing these
tabs, pull on the wire and tie from the opposite side of
the panel until it comes free. This will free up the wires
so you can re-position the panels in a way to allow
more room for parts access.
! NOTE: These wire ties will be re-inserted when service
is complete therefore should not be cut off unless you have
the same type of replacement ties.
6. Release wire tie mounting tabs in the following order:
a. Start with the wire ties below the remote control
receiver on the back left side panel.
b. Proceed to the wire ties along the upper housing
panel above the receiver, (below the flicker rod) and
work your way from left to right.
c. The last tab to be released will be right below the
light bulb on the right.
7. Pull this upper panel farther down as much as you can
and reposition it to allow access to the switch housing
above this panel on the top right hand side.
8. Locate the 3-Position Switch.
11
9. One lead of the power cord is a “Piggy-Back” connection at the 3-Position switch, which connects 2 wires on
to one prong on the switch.
10. Separate the orange wire from the “Piggy-back” connector on the white wire from the power cord.
11. Disconnect the wire nut connected to the other half of
the power cord with the group of white “neutral” wires.
12. With a pair of needle nose pliers, squeeze the strain
relief bushing that holds the power cord in place onto
the back panel remove the cord.
13. Feed the new power cord through the back panel and
squeeze the new strain relief in place on the cord and
then onto the back panel.
14. Re-connect wires at the “ON/OFF” switch and the wire
nut.
15. Push all of the mountable wire ties back into the correct holes on the housing panels making sure they are
secure. You will have to move the panel up closer into
the upper cavity. This will greatly reduce the amount
of lead or give in the wires and the workspace, on the
unit.
! NOTE: If the wire ties are not securing properly, use a
flat instrument to slightly spread the tabs farther apart and
then re-insert into the appropriate holes in the panel.
16. Re-assemble the firebox and cabinet in reverse order,
taking care that the wires are guided through the cutout
openings on the left and right of the housing panels
and no wires are touching the heater assembly blower/
fan once re-assembled.
