Ventilation Air (Cont.)
INSTALLATION
Check Gas Type
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must
provide two permanent openings: one within 12" of the ceiling and
one within 12" of the floor. Connect these items directly to the
outdoors or spaces open to the outdoors. These spaces include attics
and crawl spaces. Follow the National Fuel Gas Code ANSI Z223.1/
NFPA 54, Section 5.3, Air for Combustion and Ventilation for
required size of ventilation grills or ducts.
IMPORTANT: Do not provide openings for inlet or outlet air into
attic if attic has a thermostat-controlled power vent. Heated air
entering the attic will activate the power vent. Any outside air ducts
and/or ash dumps in the fireplace shall be permanently closed at the
time of appliance installation.
INSTALLATION
CAUTION: This fireplace insert creates warm air
currents. These currents move heat to wall surfaces
next to fireplace insert. Installing fireplace insert next
to vinyl or cloth wall coverings or operating fireplace
insert where impurities (such as, but not limited to,
tobacco smoke, aromatic candles, cleaning fluids, oil
or kerosene lamps, etc.) in the air exist, may discolor
walls or cause odors.
WARNING: A qualified service person must in-
stall fireplace insert. Follow all local codes.
WARNING: Never install the fireplace insert
• in a bedroom or bathroom
• in a recreational vehicle
• where curtains, furniture, clothing, or other flam-
mable objects are less than 42 inches from the
front, top, or sides of the fireplace insert
• in high traffic areas
• in windy or drafty areas
NOTICE: This heater is intended for use as supple-
mental heat. Use this heater along with your primary
heating system. Do not install this heater as your
primary heat source. If you have a central heating
system, you may run system’s circulating blower
while using heater. This will help circulate the heat
throughout the house. In the event of a power outage,
you can use this heater as your primary heat source.
WARNING: Before installing in a solid fuel burn-
ing fireplace, the chimney flue and firebox must be
cleaned of soot, creosote, ashes, and loose paint by
a qualified chimney cleaner.
Note: Your Vanguard fireplace insert is designed to be used in zero
clearance installations. Wall or framing material can be placed
directly against any exterior surface on the rear, sides, or top of your
fireplace insert, except where standoff spacers are integrally at-
tached. If standoff spacers are attached to your insert, these spacers
can be placed directly against wall or framing materials.
IMPORTANT: Vent-free heaters add moisture to the air. Although
this is beneficial, installing fireplace in rooms without enough
ventilation air may cause mildew to form from too much moisture.
See Air for Combustion and Ventilation, pages 5 through 7.
IMPORTANT: Make sure the fireplace insert is level. If fireplace
insert is not level, log set will not work properly.
CHECK GAS TYPE
Use the correct gas type (natural or propane/LP) for your unit. If your
gas supply is not correct, do not install fireplace insert. Call dealer
where you bought fireplace insert for proper type fireplace insert.
WARNING: Make sure the selector switch is in the
OFF position before installing heater
