be voided, and serious fire, health or other safety hazards
may result from any of the following actions:
•
Installation of any damaged Direct Vent compo-
nent.
•
Unauthorized modification of the Direct Vent Sys-
tem.
•
Installation of any component part not manufactured
or approved by DuraVent.
•
Installation other than as instructed by DuraVent and
the appliance manufacturer.
Consult your local building codes before beginning the
installation. Have the existing installation inspected by a
qualified chimney sweep or professional installer, prior to
converting to direct vent. The existing chimney system must
be in serviceable condition, and functionally sound. The
direct vent conversion described herein applies only
to factory-built metal ceiling-supported type systems
and masonry through-the-wall type systems. NOTE:
You cannot install a Conversion Kit in a through-the-
wall type factory-built metal chimney.

Two different types of direct vent conversion systems are
described here. One is through an existing factory-built
metal chimney going through the ceiling. The other is
through the wall of an existing masonry chimney. Follow
the appropriate directions for your situation.
A typical direct vent conversion of a factory-built metal
chimney is shown in Figure 43. The concept of the direct
vent conversion is to connect an adapter to an Underwrit-
ers Laboratories listed 4" diameter aluminum flex pipe
(DuraVent's DuraFlex is an example of a UL listed flex
pipe). The flex is then passed down through the center of
the existing metal chimney system. Three sizes of termi-
nation caps are available which should fit most sizes and
makes of metal chimney systems. The Retro Connector
(909B) is then attached to the bottom of the flex pipe. Both
the cap adapter and retro connector are attached to the
existing chimney with sheet metal screws. The appliance
is then connected to the chimney with appropriate black
direct vent pipe and an adjustable length section.
A typical conversion of an existing masonry chimney is
shown in Figure 45. For installation through the wall of
an existing masonry chimney, a cap adapter (985K) and
flashing are used at the top of the masonry chimney. The 4"
aluminum liner is connected to the adapter and is passed
down the chimney and out through the masonry wall. This
is attached to the retro connector (909B) which is in turn,
attached to the masonry wall and is then connected to the
direct vent pipe leading to the appliance.
