PRODUCT REFERENCE INFORMATION
We recommend that you record the following important information about your replace.
Bi-Fold Glass Doors
Your fireplace can be fitted with beautiful, easy-
to-install bi-fold glass doors.
Model LBF doors have a matte black nish.
Model LBF-BS doors have a beautiful brushed
stainless finish.
ACCESSORY COMPONENTS
To ensure warranty and prevent a
potential fire hazard, do not use any
other doors on these appliances.
7. Is your wood fuel too wet or unseasoned?
Or does it contain some chemical substance that
causes sputtering, smoking and toxic fumes?
8. Figure 5 illustrates the correct height of
your chimney top. It is unlikely that your
installation does not adhere to the installation
instructions. However, if not correct, you could
experience an unusual downdraft. Usually,
the best solution is to increase the chimney
height. This may also be necessary if nearby
trees, adjoining roof lines or a hill is causing a
downdraft condition.
9. Remember, your fireplace has been designed
as a supplemental heating device only, it is not
intended to heat your entire home.

5. If smoking occurs an hour or two after light-
ing the fire, perhaps your well-insulated house
is too airtight and there is scarcely any way
for replacement air to enter and feed the fire.
Check to see if your outside combustion air kit
(if installed) is open. Check outside to ensure
no obstructions are in front of exterior air entry.
Open a window slightly, open doors to one or
two rooms and see if this stops the smoking.
6. Is a vent fan, exhaust hood or central heat-
ing/cooling system stealing combustion air
from your replace? If their volume is high
enough, this can cause negative pressure and
an unwanted downdraft – and smoking.
