USSC Ambiance B9945L Installation And Operation Instructions Manual Download Page 3

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 9945N/9945L 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.
