GENERAL
INFORMATION
This gas room heater should be installed by a
qualified installer in accordance with local building
codes and with current National Fuel Gas Code.
ANSI Z223.1.
This heater should not be installed in a confined
space unless provisions are made for adequate
combustion and ventilation air.
The National Fuel Gas Code defines a confined
space as "a space whose volume is less than 50
cubic feet per 1000 BTU per hour (4.83 per kw) of
the aggregate input rating of all appliances
installed in that space" and unconfined space as
"space."
.If the area in which the heater may be operated is
smaller than that defined as an "unconfined
space," provide adequate combustion and venti-
lation air by one of the methods described in the
National Fuel Code, ANSI Z223.1, 1992, Section
5.3.
Make it a practice to have all of your gas
heaters checked annually. More frequent
cleaning may be required due to excess lint
and dust from carpeting, bedding material, etc.
6. Control compartments, burners and air pas-
sages in this heater should be kept clean and
free of dust and lint. Make sure that the gas
valve and pilot light are turned off before you
attempt to clean this unit.
7. Under no circumstances should any solid fuels
(wood, coal, paper or cardboard, etc.) be used
in this heater.
8. Keep the area around your heater clear of
combustible materials, gasoline and other
flammable vapor and liquids. This heater
should not be used as a drying rack for cloth-
ing, nor should Christmas stockings or decora-
tions be hung in the area of it.
9. Upon no circumstance should this Heater be
installed in a chase or used with any other
mantel than the approved FPS1212 or
FPS1214 mantels.

HEATER PLEASE NOTE THE FOllOWING:
1. This heater gives off high temperatures and
should be located out of high traffic areas and
away from furniture and draperies.
2. Children and adutts should be alerted to the
hazards of the high surface temperatures of
this heater and should stay away to avoid
burns or ignition of clothing.
3. Children should be carefully supervised when
they are in the same room as your heater.
4. Under no circumstances should this heater be

should be carried out by a qualified service
person. A professional service person should
be contacted to inspect this heater annually.
10. Do not install heater in bedroom or bathroom.
SAFETY DEVICES
Adequate combustion and ventilation air must be
provided. The flow of combustion and ventilation
air MUST NOT be obstructed.
Provide adequate clearances around the air
opening into the combustion chamber; and ad-
equate accessibility clearance for servicing and
proper operation. NEVER obstruct the front open-
ing of the heater or cover the top and bottom
louvres.
These heaters are equipped with a pilot system
featuring an Oxygen Depletion Sensor (O.D.S.)
shut-off device. All unvented heaters are required
to have this system. The O.D.S. pilot will shut
down the heater when there is not enough fresh
air available.
