suggestions which will result in enhanced installation, reliability, or
operation.
To minimize the possibility of serious personal injury, fire, damage to
your furnace, or improper operation, carefully follow these safety rules
which apply to both direct-vent and non-direct vent applications:
• Your new gas furnace may have been installed in one of two ways, as
a direct-vent
(2-pipe-Fig.
2) application or as a non-direct vent
(1-pipe-Fig.
3) application.
• In a direct-vent (2-pipe) application, your furnace uses air from
outside the home for combustion and vents flue gas to the outdoors.
This type of application will have two pipes running from the furnace
to the outdoors. In some cases, the inlet air pipe may be located in an
area that has access to outdoor air, such as an attic. In all cases, the
outlet vent pipe must be routed to the outdoors (see
application, the vent and air-intake pipes must terminate outside the
structure and must not be obstructed in any way. Do not block or
obstruct air openings on furnace or spaces around furnace.
• In a non-direct vent (1-pipe) application, your furnace uses air from
adjacent to the furnace for combustion and vents flue gas to the
outdoors. This type of application will have only one pipe running
from the furnace to the outdoors (see
terminate in the same space as the furnace and is the source of
combustion air for your furnace. Therefore, the furnace must not be
enclosed in an airtight room or be sealed behind solid doors. It must
have adequate airflow for efficient combustion and safe ventilation.
Do not obstruct the combustion-air pipe in any way. The vent pipe
must terminate outside the structure and must not be obstructed in any
way. Do not block or obstruct air openings or space around furnace.
