The Simpson Dura-Vent warranty will 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 manufac-
tured or approved by Simpson Dura-Vent.
•
Installation other than as instructed by Simpson
Dura-Vent 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 sys-
tem 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 chim-
ney.

General Installation
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. Fol-
low 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
Underwriters Laboratories listed 4" diameter aluminum
flex pipe (Simpson Dura-Vent's DuraFlex is an ex-
ample of a UL listed flex pipe). The flex is then passed
down through the center of the existing metal chimney
system. Three sizes of termination caps are avail-
able 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 chim-
ney. 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.
