4)
Assemble the desired lengths of Black Pipe
and Elbows necessary to reach from the ap-
pliance adaptor up through the support box
and flashing to proper height as per Diagram
12, local codes or the "Exterior Vent Terminal
Locations" section. Ensure that all pipe and
elbow connections are in their fully twist lock
position.
5)
Ensure vent is vertical and secure flashing to
the roof with roofing nails. Slide the storm
collar over the pipe section and seal with a
mastic.
6)
Twist lock the vent cap on to the last section.
Support Extensions - Round
(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" (559mm). The
extension is attached to the support using the
eight metal screws provided. Be sure there is at
least a 2" (51mm) overlap where the extension
joins the support.
HIGH ELEVATION
This unit is approved in Canada for altitude to
4500 ft. (CAN/CGA-10.17-M91). For Natural Gas
installations above 4500 feet, follow current CAN/
CSA-B149.1.
GAS CONNECTION
The gas connection is a 3/8" NPT 90
o
elbow. The
gas line can be rigid pipe or to make installation
easier, use a listed flexible connector and/or copper
tubing if allowed by local codes. Since some mu-
nicipalities have additional local codes it is always
best to consult with your local authorities and the
CAN/CSA B149.1 installation codes.
For USA installations follow local codes and/or the
current National Fuel Gas Code, ANSI Z223.1.
When using copper or flex connectors use only
approved fittings. Always provide a union so that
gas lines can be easily disconnected for burner
and/or valve servicing. Flare nuts for copper lines
and flex connectors are usually considered to
meet this requirement.

CATHEDRAL CEILINGS
Round Support (RDS) &
Square Support (SQS)
If your home has a cathedral ceiling (no attic space
between the ceiling and the roof), install the chimney
and support as follows.
1)
Situate the chimney in a convenient location as
near as possible to the appliance outlet. Cut
and frame a hole in the roof for the support.
The sides of this hole must be vertical with 1
1/4" (32mm) clearance.
2)
Place the support in the opening. Lower it to
the correct height as determined by the table
and diagram below.
Using a level, make sure the support is verti-
cal. If the support extends above the roof,
cut it flush with the top of the roof. Nail the
support to the frame opening using (8) 3"
spiral nails or #8 x 1-1/2" screws.
Note: If you are using a 6" square support you
may find it difficult to screw it in place
because it is fairly small inside.
Simpson Dura-Vent has provided angle brack-
ets with this support which can be screwed
to the outside of the support box and nailed
to surrounding framing as required. Use a
minimum of four #8 x 1/2" screws per bracket.
In some cases these brackets may need to
be trimmed (e.g.: to fit under a flashing).
Place the Finish Collar around the support
and fasten it to the ceiling using the screws
provided.
3)
Use appropriate roof flashing. Place the
flashing under the upper shingles and on top
of the lower shingles approximately half of the
flashing should be under the shingles.

Note: Prior to any pressure testing of the gas
supply piping system that exceeds test
pressures of 1/2 psig, this appliance must
be disconnected from the piping system.
If test pressures equal to or less than 1/2
psig are used then this appliance must
be isolated from the piping system by
closing its individual manual shut-off
valve during the testing.
