Note: If installing termination on a siding
covered wall, a vinyl siding standoff or
furring strips must be used to ensure that
the termination is not recessed into the
siding. The four wood screws provided
should be replaced with appropriate fas-
tenersforstucco,brick,concrete,orother
types of sidings.
5) Before connecting the horizontal run of
vent pipe to the vent termination, slide the
black decorative wall thimble cover over

provided to connect the strips to the pipe.
Bend any remaining portion of the sheet
metal strip back towards the vent cap, so
it will be concealed by the decorative wall
thimble cover. See diagram 6.
4) If installing the vent termination to a wall
with vinyl siding, the Vinyl Siding Standoff
must be used. Attach the Vinyl Siding
Standoff to the Horizontal Vent Termina-
tion, but first run a bead of non-hardening
mastic around its outside edges, so as to
make a seal between vent cap and the
standoff. Install the Vinyl Siding Standoff
(Part# 950)betweenthe ventcapandthe

Galvanized pipe and elbows may be uti-
lized in the attic as well as above the
roofline. Thegalvanizedfinishisdesirable
above the roofline due to its higher corro-
sion resistance.
Continue to add pipe sections through the
flashing until the height of the vent cap
meets the minimum height requirements
specifiedindiagram12orlocalcodes. Note
that for steep roof pitches, the vertical
heightmust beincreased. Apoor draft,or
down drafting can result from high wind
conditions near big trees or adjoining roof
lines, in these cases, increasing the vent
height may solve the problem.

(RDSE) or Square (SQSE)
Steep pitched cathedral ceilings may require
the use of a support extension. This piece fits
down inside the support and can be adjusted
to increase the support's length by up to 22".

TO ADIRECT VENT
SYSTEM
General
There are two different types of direct vent
conversion systems listed below. Follow the
appropriate directions for your installation.
A) Throughanexistingfactorybuiltmetalchim-
ney going through the ceiling: A typical
conversionofthistypeisshownindiagram
1.The conceptofdirectventconversion is
to connect an adaptor to an Underwriters
Laboratories (UL) listed 4 inch diameter
aluminum flex pipe which is then passed
down through the center of the existing
metal chimney system. Three sizes of Top
AdaptorsareavailablefromSimpsonDura-
Vent. The Retro Connector (909B) is at-
tachedtothebottomoftheflexpipe.TheTop
Adaptor and the Retro Connector are at-
tached to the existing chimney with sheet
metal screws. The appliance is then con-
nected to the chimney with appropriate
black direct vent pipe and an adjustable
length section.
B) Through the wall of an existing masonry
chimney: A typical conversion of an exist-
ing masonry chimney is shown in Diagram
6. A Top Adaptor (985K) and Flashing are
usedatthetopofthemasonrychimney.The
4 inch aluminum liner is connected to the
adaptor and is passed down the chimney
and out through the masonry wall and
attached to the Retro Connector (909B).
The Retro Connector is attached to the
masonry wall and then connected to the
direct vent pipe leading to the appliance.

tion,contactaqualifiedservicepersonto
determine if a negative pressure and/or

is corrected.
Approved for US Installations Only
The use of an existing chimney as an air
intake is not covered under the ANSI
Z21.88b-1999, CSA 2.33b-M99 test meth-
ods and the resulting ITS/WHI product
certification. The code Authority Having
Jurisdiction must be consulted prior to
proceedingwiththisinstallationmethod.
Converting a Factory Built Metal
Chimney
1) Remove the existing chimney cap.
2) Measure the distance from the top end of
the chimney to the bottom of the ceiling
support box, add 3" (76mm) to this meas-
urement,andcutasectionofthe4"flexpipe
to that length (the flex should already be
extended to its nominal length).

Converting a Masonry Chimney
Important: The existing masonry flue
openingneedsto have anareaofatleast
a 36 sq. in. to insure proper intake/ex-
haust flow.
1) Before cutting any holes, assemble the
desiredsectionsofblackdirectventpipeto
determine the center of the masonry pen-
etration.

This allows the Retro Connector to mount

3) SecuretheFlashing(Part#705C)tothetop
of the masonry chimney using a bead of
non-hardening sealant-adhesive. If the
Flashing is larger than the top of the chim-
ney, then cut and fold flashing as needed
to fit chimney. Diagram 7.
