INSTALLATION
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.

stall fireplace insert. Follow all local codes.

• 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
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: 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 4 through 6.
IMPORTANT: Make sure the fireplace insert is level. If fireplace
insert is not level, log set will not work properly.
