9. This unit complies with ANSI Z21.11.2 unvented heaters
standard.
10. Do not install the DFX Model in a bathroom or bedroom.
The DBX Model may be installed in a bedroom, but not
in a bathroom.
11. Correct installation of the ceramic fiber logs, proper loca-
tion of the heater, and annual cleaning are necessary to
avoid potential problems with sooting. Sooting, resulting
from improper installation or operation, can settle on sur-
faces outside the fireplace. See log placement instructions
for proper installation.
12. Avoid any drafts that alter burner flame patterns. Do not
allow fans to blow directly into fireplace. Do not place
a blower inside burn area of firebox. Ceiling fans may
create drafts that alter burner flame patterns. Sooting and
improper burning will occur.
13. CAUTION: Candles, incense, oil lamps, etc. produce
combustion by-products including soot. Vent-free appli-
ances will not filter or clean soot produced by these types
of products. In addition, the smoke and/or aromatics
(scents) may be reburnt in the vent-free appliance which
can produce odors. It is recommended to minimize the
use of candles, incense, etc. while the vent-free appliance
is in operation.
14. An unvented gas-fired heater uses air (oxygen) from the
room in which it is installed. Provisions for adequate
combustion and ventilation air must be provided. See
installation guidelines.

Read these instructions carefully before installing or trying to operate a vent-free gas heater in this fi rebox.

7. To prevent malfunction and/or sooting, an unvented
gas heater should be cleaned before use at least
annually by a professional service person. More
frequent cleaning may be required due to excessive
lint from carpeting, bedding material, etc. It is
imperative that control compartments, burners and
circulating air passageways be kept clean.

carbon monoxide poisoning are similar to the flu with
headaches, dizziness and/or nausea. If you have these
signs, obtain fresh air immediately. Have the heater ser-
