Note:
a) The horizontal run of vent should have
a 1/4 inch rise for every 1 foot of run
towards the termination. Never allow
the vent to run downward. This could
cause high temperatures and may
present the possibility of a fire.
b) The location of the horizontal vent ter-

alllocalandnationalbuildingcodes,and
must not be blocked or obstructed. For

This appliance is designed to be attached to two 3" (76mm) co-linear aluminium flex running the full length of the chimney. See the Venting
Arrangementscharton page10 forminimum andmaximum fluelengths.See chart belowfor minimumdistancesfrom roof.Periodically checkthat
the vent is unrestricted.
Masonry chimneys may take various contours which the flexible liner will accommodate. However, keep the flexible liner as straight as
possible, avoid unnecessary bending.
The Air Intake pipe must be attached to the inlet air collar of the termination cap.

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 conceptofdirectvent conversionis
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.

Approved for US Installations Only
The use of an existing chimney as an air
intake is not covered under the ANSI

ods and the resulting ITS/WHI product
certification. The code Authority Having
Jurisdiction must be consulted prior to

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).

follow local codes and/or the current National
Fuel Gas Code, ANSI Z223.1.
When using copper or flex connectors use
onlyapprovedfittings.Alwaysprovideaunion
sothatgaslinescanbeeasilydisconnectedfor
