INSTALLATION
Note:
Your Vanguard fireplace insert is de-
signed to be used in zero clearance installa-
tions. 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
attached. If standoff spacers are attached to
your insert, these spacers can be placed di-
rectly against wall or framing materials.
IMPORTANT:
Vent-free heaters add mois-
ture 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 Com-
bustion and Ventilation, pages 4 through 6.
IMPORTANT:
Make sure the fireplace in-
sert is level. If fireplace insert is not level,
log set will not work properly.
CHECK GAS TYPE
Use only natural gas. If your gas supply is
not natural gas, do not install fireplace in-
sert. Call dealer where you bought fireplace
insert for proper type fireplace insert.
