13. Avoid any drafts that alter burner fl ame patterns. Do not 
allow fans to blow directly into fi replace. Do not place 
a blower inside burn area of fi rebox. Ceiling fans may 
create drafts that alter burner fl ame patterns. Sooting 
and improper burning will occur.
14. CAUTION: Candles, incense, oil lamps, etc. produce 
combustion byproducts including soot. Vent-free 
appliances will not fi lter or clean soot produced by 
these types of products. In addition, the smoke and/or 
aromatics (scents) may be reburned 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. Provi-
sions for adequate combustion and ventilation air must 
be provided. 
16. This heater shall not be installed in a room or space 
unless the required volume of indoor combustion air is 
provided by the method described in the National Fuel 
Gas Code, ANSI Z223.1/NFPA 54, the International 
Fuel Gas Code or applicable local codes.
17. Keep room area clear and free from combustible 
materials, gasoline and other fl ammable vapors and 
liquids.
18. Unvented gas heaters are a supplemental zone heater. 
They are not intended to be the primary heating appli-
ance. 
19. Unvented gas heaters emit moisture into the living 
area. In most homes of average construction, this 
does not pose a problem. In houses of extremely 
tight construction, additional mechanical ventilation is 
recommended. 
20. During manufacturing, fabricating and shipping, various 
components of this appliance are treated with certain 
oils, fi lms or bonding agents. These chemicals are not 
harmful but may produce annoying smoke and smells 
as they are burned off during the initial operation of the 
appliance; possibly causing headaches or eye or lung 
irritation. This is a normal and temporary occurrence.
