the vent termination clearance requirements
fromdecks,windows,soffits,gasregulators,air
supply inlets and public walkways as specified
inthe"ExteriorVentTerminalLocations"section
and in your local building codes.
The gas appliance and vent system
must be vented directly to the outside
of the building, and never be attached
to a chimney serving a separate solid
fuel or gas-burning appliance.
Eachdirectventgasappliancemustuseitsown
separate vent system. Common vent systems
are prohibited.
SAFETY PRECAUTIONS
FOR THE INSTALLER
1) Wear gloves and safety glasses for protec-
tion.
2) Exercise extreme caution when using lad-
ders or on roof tops.
3) Be aware of electrical wiring locations in
walls and ceilings.
See the "Exterior Vent Terminal Locations"
section for the requirements. .
When planning your installation, it will be nec-
essary to select the proper length of vent pipe
for your particular requirements. Determine the
minimum clearance to combustibles from the
rear of the unit to the wall. It is also important to
note the wall thickness. Before cutting the vent
hole through the wall ensure that ALL vent and
termination clearances (see the "Exterior Vent
Terminal Locations" section) will be met.
*If this is an outside corner, the minimum distance between the vent and the outside corner
is 12" (30cm). See "F" on the diagram in the "Exterior Vent Terminal Locations" section.
NOTE: Ensure compliance with the outside vent terminal location before cutting hole as both dimensions must be met.
Forcornerinstallation,Restrictormust

1) Set the unit in its desired location. Check to
determine if wall studs are in the way when
the venting system is attached. If this is the
case, you may want to adjust the location
of the unit.

If the Snorkel Termination must be
installed below grade, i.e. basement
application, proper drainage must be
provided to prevent water from enter-
ing the Snorkel Termination. Refer to
Dura-Vent Installation instructions for
details.. Do not attempt to enclose the
Snorkelwithinthewall,oranyothertype
of enclosure.
4) Install wall penetration heat shield in the
center of the 9-1/2" round hole and attach
with wood screws. The four wood screws
provided should be replaced with appropri-
ate fasteners for stucco, brick, concrete, or
other types of sidings. Dia. 3.

Masonry chimneys may take various contours which the flexible liner will accommodate. However, keep the flexible liner as straight as possible,
avoid unnecessary bending.

Converting a Factory
Built Metal Chimney
1) Remove the existing chimney cap.
2) Measurethedistancefromthetopendofthe
chimneytothe bottom ofthe ceiling support
box, add 3" (76mm) to this measurement,
and cut a section of the 4" flex pipe to that
length (the flex should already be extended
to its nominal length).
3) Connect the end of the flex pipe section to
the underside of the Top Adaptor using 3
sheet metal screws.
Diagram 2.
Diagram 3
Diagram 4
Diagram 5
4) Pass the flex pipe down through the center of
the chimney system, and center the adaptor
on the top of the chimney pipe. Drill four 1/8"
diameter holes through the adaptor and into
the chimney top. Insure that you are in fact,
drilling into the metal on the chimney. Twist-
lock the Termination Cap (Part# 980 or 991)
onto the Adaptor. (Diagram 3 and 4).
5) Pull the flex pipe down through the ceiling
supportbox,untilitprotrudesapproximately
3"(76mm).ConnecttheflexpipetotheRetro
Connector by slipping it into the
4-3/4" diameter sleeve on the top side of
the Connector. Use 3 sheet metal screws
to assemble these two parts.
6) Push the flex pipe back up into the ceiling

attach it to the support box, or decorative
sleeve for double wall solid packed pipe,
with the sheet metal screws (supplied).

punched. Diagram 5.

MASONRY CHIMNEY
Important: The existing masonry flue open-
ing needs to have an area of at least a 36 sq.
in. to insure proper intake/exhaust flow.
1) Before cutting any holes, assemble the
desired sections of black direct vent pipe
to determine the center of the masonry
penetration.
Diagram 6
2) Oncethecenterpointofthepenetrationhas
beendetermined,cuta6"(152mm)dia.hole
in the masonry. Be careful, if the hole is too
large,theRetroConnectormightnotmount
properly, and if the hole is too small, then
the appliance might starve for intake air. If
there is a frame wall in front of the masonry
wall, cut and frame a 10" (254mm) clear
squareopeninginthewall(centeredaround
the6"(152mm) masonry opening). IFthere
is sheet rock only (no studs) in front of the
masonry, the 10" (254mm) clear opening is
stillneeded,butdoesnotneedtobeframed.
This allows the Retro Connector to mount
directly on the masonry and provide clear-
ance to the combustibles. Diagram 11.
3) Secure the Flashing (Part # 705C) to the
top of the masonry chimney using a bead
of non-hardening sealant-adhesive. If the
Flashingislargerthanthetopofthechimney,
then cut and fold flashing as needed to fit
chimney. Diagram 7.
Diagram 7
4) To determine the length of flex required,
measure from 3" (76mm) above the top of
the Flashing down to the level of the open-
ing. Add to this measurement the distance
fromthecenterofthechimneytooutthrough
the wall. Cut a piece of 4" flex to this length
(the flex should already be extended to its
nominal length).
5) Connect the 4" flex liner to theTop Adaptor
(Part # 985K) using 3 sheet metal screws.
Diagram 2.
6) Feed the 4" flex liner through the Flashing
into the chimney. Continue to feed the liner
out through the opening in the masonry
wall.
