able blower allows you to select the fan speed
you desire. The blower circulates heated air
from the firebox into the room. Use of blower
is optional.

Today's homes are built more energy efficient
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.
