VENTED NATURAL GAS LOGS
AIR FOR
COMBUSTION AND
VENTILATION
WARNING: This appliance
shall not be installed in a con-
fined space or unusually tight
construction unless provisions
are provided for adequate com-
bustion and ventilation air. Read
the following instructions to in-
sure proper fresh air for this and
other fuel-burning appliances in
your home.
Today's homes are built more energy effi-
cient than ever. New materials, increased
insulation, and new construction methods
help reduce heat loss in homes. Home owners
weather strip and caulk around windows and
doors to keep the cold air out and the warm air
in. During heating months, home owners
want their homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning
appliances need fresh air for proper com-
bustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and
fuel burning appliances draw air from the
house to operate. You must provide ad-
equate fresh air for these appliances. This
will insure proper venting of vented fuel-
burning appliances.
INSTALLATION
CAUTION: Do not remove the
metal data plates attached to the
burner pan. The data plates contain
important warranty information.
WARNING: Before installing
in a solid fuel burning fireplace,
the chimney flue and firebox must
be cleaned of soot, creosote,
ashes, and loose paint by a quali-
fied chimney cleaner. Creosote
will ignite if highly heated. A dirty
chimney flue may create and dis-
tribute soot within the house. In-
spect chimney flue for damage.

repair of this appliance must be
performed by a qualified installer,
service agency, company or gas

manufacturer's instructions and
all codes and requirements of the

VENTING SPECIFICATIONS
FOR INSTALLATION
The fireplace chimney flue and vent must be
drafting properly. To check the vent for
proper drafting: Light a tightly rolled news-
paper on one end and place it at the inside
front edge of the fireplace. Observe the
smoke and be sure the vent is properly
drawing it up the chimney. If the smoke
spills out into the room, extinguish the flame
and remove any obstruction until proper
venting is achieved.
The chimney flue must remain open a mini-
mum of 3" at all times during the operation
of this log set.
