10.  This unit complies with ANSI Z21.11.2-2001 Unvented 

Heaters and also complies with ANSI Z21.60-2000 Deco-
rative Vented Appliances for Solid Fuel Burning Fire-
places. State and local codes may only allow operation 
of this appliance in a vented configuration. Check your 
state or local codes. For vented operation, see “Vented 
Instructions” in this manual.

11.  Do not install the heaters in a bathroom or bedroom.
12.  Correct installation of the ceramic fiber logs, proper 

location of the heater, and annual cleaning are necessary 
to avoid potential problems with sooting. Sooting, 
resulting from improper installation or operation, 
can settle on surfaces outside the fireplace. See log 
placement instructions for proper installation.

13.  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.

14.  Caution: Candles, incense, oil lamps, etc. produce 

combustion byproducts 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. 

15.  This is an unvented gas-fired heater. It uses air (oxygen) 

from the room in which it is installed. Provisions for 
adequate combustion and ventilation air must be pro-
vided. See page 8.
