Preliminary steps to prepare for the installation of
the ShadowLight XL Fireplace Insert

Remove the chimney cap if one exists so that the flue
may be cleaned and the venting installed.

Remove any existing hearth accessories such as glass
doors, spark screens, andirons, and grates.

Clean the chimney thoroughly to remove ash, soot,
and any obstructions, and then clean ash, soot, dust,
and debris from the fireplace.

The damper must be locked open to allow the 3"
venting to pass through. If it is necessary to modify
the damper area to allow passage of the venting, the
modifications should be allowed under local codes.
Confirm any planned changes with local building
officials.

Feed chimney liners down the chimney and through
the damper.If the fireplace opening does not allow
enough room to connect the flue liners to the stove
it is necessary to separate the exhaust/ intake pipe
adapter from the stove body.
Approximately 4 inches clearance above the top of
the glass door is needed to allow connection of the
liners. This must be determined by the installer.

3

Remove the screw, washer and spacer from the
center of the rear brick panel. Using one hand,
gently push out on the side brick /relief door to allow
clearance for removing the rear brick panel.

2

Door Latches

Open the glass door by pulling out on the 2 latches
located on the bottom of the door frame. Pull the
bottom out a couple of inches and lift the door off
of the stove body and set safely out of the way.
Remove the bag of rock wool, packaging materials
and log set from inside the firebox.

Skip steps 3 thru 5
not need removed for in

if intake / exhaust adapter does

stallation.

4

Remove 2 screws holding exhaust cover plate onto
the rear of the firebox and remove cover.

Using a 1/2” deep well socket loosen the nut that
was under the exhaust cover plate until it is flush
with the end of the threads. Pull the exhaust clamp
down from notch in firebox top. Lift the clamp
assembly up and disconnect it from the intake /
exhaust adapter.

Remove exhaust adapter from the top of the stove
assembly being careful not to damage the sealing
gasket.

The flue restrictor can be installed after flex pipes
are connected and stove is in fireplace opening.
To change or install restrictor remove glass door
then remove log . Next remove screw, washer and
spacer in the rear brick panel and remove the brick
panel while holding relief door open with one hand.
Remove the 2 screws holding the exhaust cover
onto the rear of the firebox.

To remove a restrictor push the front of the plate
upward and pull down on the rear side bringing it
into the firebox.

To install a restrictor, hold plate vertically and slide
up into exhaust connector through the back of the
firebox. Push bottom of plate back allowing it to set
onto lip inside the exhaust adapter.

8

Look through to connect “J” bolt.

Flue
Restrictor

Determine the flue restrictor needed for this
application and install into the exhaust pipe on the
stove adapter.

● Propane uses the 2” ID restrictor for 10’ to 16’ and

the 1.75” ID for the 16’ to 36’ chimneys.

● Natural gas uses no restrictor from 10’ to 16’ and

the 1.75” restrictor from 16’ to 36’.

Lay cardboard or an old cloth onto the fireplace
hearth to keep from damaging it. If the pipe adapter
has been removed from the stove body connect the
flex pipes to the intake/exhaust adapter assembly,
be sure to use the correct pipe on the exhaust
connector, the one that was marked with paint
earlier. Tie a string to the exhaust adapter so you
can pull the adapter onto stove body.

Check stove to opening side clearance. If there is
not enough room to reach beside stove while it is
installed you may want to remove the gas line from
the valve assembly and connect it to your supply
line inside the fireplace first, then reconnect to the
gas valve.

Set stove into fireplace opening. Connect the pipe
adapter or flex liners to the stove. To reconnect
the pipe adapter use the string or reach through
the exhaust passage and pull the adapter onto
the stove body. While looking through the center
exhaust port located toward the front of the firebox,
connect the “J“ bolt to the adapter. Next slide the
clamping adapter into the notch in the firebox
top and tighten the nut. Remove the string when
completed.

Connect the gas pipe to the stove unit. If the pipe
adapter was removed from the stove, replace all
components back onto the stove in the reverse
order from which they were removed.

Place rock wool on burner as shown above. The
wool should be placed loosely and lightly. This
wool forms the glowing ember bed and will look
different depending on placement. Reinstall the
glass door assembly and close the latches.

Do not stike glass or close door with excessive
force. Breakage of glass and/or damage to door
may result.

10

Place log set in firebox. Center the logs right to left
and push back against the log stop.

The power cord comes out the right side of the unit
from the factory. The power cord may be changed
to the left side before installing the face. Start by
bringing the plug end of the cord back through the
side of the firebox, and lifting the strain relieved
cord section up from body notches. Keeping the
cord along the front of the stove bottom run the
plug end under the label holding brackets and
out the same area on the other side of the stove
body. Press the strain relieved cord section into
the notches on the left side of the stove body and
secure the cord to the front bottom section of the
stove using wire ties.

12

Back out the 4 face clamping bolts far enough
to install the face. Slide the face onto the firebox
assembly until the slots are just fully under the
heads of the bolts and are all even, then tighten
the 4 bolts as shown above. Check to see if the
back of the stove face meets with the fireplace
opening as neatly as possible, some adjustment
may be necessary. If the face is slid too far back
under the bolts the glass door will not be able to
be removed without taking the face off first. Some
applications may be required to be installed that
way.
