approved.
Two 3” chimney liners (#09400) are used with Alpine
LXi series inserts. One liner will supply the
combustion air to the fireplace, the other will vent the
flue gases. Also required are:
• an appliance adapter which enables the liners to
be fastened to the insert (#00000)
• a co-linear adapter which enables the liners to be
joined with the termination cap (#09318)
• flashing to seal the flue tile
• a termination cap (#09317)
• two band clamps to fasten the liners to the
appliance adapter (#08530)
Installation Procedure
1) Measure the distance from the top of the flue tile
to the approximate top of the insert.
2) Add about 6” to your measurement and carefully
stretch each liner to that length.
3) Cut and bend the flashing to form a box type cap
to fit over the flue tile (the oval lip on the flashing
must be facing up).
4) Take the flashing and seal it to the flue tile with
some high quality sealant (remember the oval lip
on the flashing must be facing up to deter water).
5) Lower all but one foot of the vent liner through
the flashing into the flue tile.
6) Attach the liner to the co-linear adapter (see fig.
6).
7) Push the liner onto the nipple that flows through
the adapter until it seats against the gasket
material.
8) Fasten the liner to the adapter with 3-4 sheet metal
screws.
9) Lower the liner for combustion air and fasten it to
the co-linear adapter, in the same manner as the
vent liner, to the remaining nipple.
10) Lower the adapter onto the flashing and fasten
with sheet metal screws through the tabs provided.
Seal these screws with a high quality sealant to
prevent leaking. Seal around the adapter to
flashing joint.
11) Line up the lugs on the termination cap with the
receivers on the adapter and seat and then twist
the cap on.
12) Fasten the cap to the adapter with sheet metal
screws for added strength.
13) Slide the Exhaust Vent liner over the left outlet
on the appliance adapter. (See figure 7) Secure the
liner with one 3” band clamp.
14) Attach the Combustion Air liner to the remaining
nipple on the appliance adapter. Secure the liner
with one 3” band clamp.
15) Place the appliance adapter in its approximate
final position and, if needed, adjust the liners until
no severe bends or kinks exist. Be careful not to
tear or dent the liners or pull off one of the
NOTE: Be sure to identify each liner in the
fireplace so you can make proper connections. If
the insert is vented improperly, it will not function
and may create a dangerous situation.
Note: Be sure to protect the hearth with
cardboard, thin plywood, or light sheet metal to
prevent the inset from marring , or scratching the
hearth.
Note: Take special care not to damage the gasket
material on the appliance adapter. An improper
seal will inhibit proper operation of the fireplace
insert.
