WARNING! Risk of Asphyxiation! Negative pressure can
cause spillage of combustion fumes and soot. Fire must
draft properly for safe operation.
NOTICE: Hearth & Home Technologies assumes no
responsibility for the improper performance of the replace
system caused by:
• Inadequate draft due to environmental conditions
• Downdrafts
• Tight sealing construction of the structure
• Mechanical exhausting devices
• Improper positioning of the chimney in a not-recommended
location on the roof.
NOTICE: Hearth & Home Technologies Inc. recommends the
use of direct vent appliances in basements.
