AIR FOR COMBUSTION
AND VENTILATION
WARNING:Thisheatershall
not be installed in a confined
space or unusually tight con-
structionunlessprovisionsare
providedforadequatecombus-
tion and ventilation air. Read
thefollowinginstructionstoin-
sure proper fresh air for this
and other fuel-burning appli-
ances in your home.
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.
