ARNING
CARBON MONOXIDE POISONING: Early signs of 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 serviced as it may not be operating properly.
The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas
Code, ANSI Z223.1.
The 9843N/9843L vent-free gas heater system cannot be installed in a bedroom.
Do not install the heaters in a bathroom.
WARNING: Improper installation, adjustment, alteration, service or maintenance can cause injury or
property damage. Refer to this owner's manual. Installation and service must be performed by a qualified
installer; service agency or the gas supplier.
To prevent malfunction and/or sooting, an unvented gas heater should be cleaned at least annually by a
professional service person. More frequent cleaning may be required due to excessive lint from carpeting,
etc. It is imperative that control compartments, burners and circulating air passageways be kept clean.
Correct placement of the ceramic fiber logs is necessary to avoid problems with sooting. Sooting can settle
on surfaces outside the heater and cause discoloration. See the appropriate sections of this manual for
instructions.
WARNING: Do not allow fans to blow directly into the fireplace. Avoid any drafts that alter burner flame
patterns. 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.
This is an vent-free gas-fired heater. It uses air (oxygen) from the room in which it is installed. Provisions
for adequate combustion and ventilation air must be provided. Refer to installation guidelines.
Children and adults should be alerted to the hazard of high surface temperature and should stay away to avoid
burns or clothing ignition.
Young children should be carefully supervised when they are in the same room with the appliance.
