installation
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
brackets 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.
4) Assemble the desired lengths of Black
Pipe and Elbows necessary to reach from
the appliance adapter up through the sup-
port box and flashing to proper height as
per Dia. 12, local codes or in the "Venting
Arrangement" 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".
The extension is attached to the support using
the eight metal screws provided. Be sure there
is at least a 2 inch overlap where the extension
joins the support.
High Elevation
This unit is approved in Canada for altitude to
4500 ft. (CAN/CGA-2.17-M91). For Natural Gas
installations above 4500 ft. follow current CAN/
CGA-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.

8) Ensure vent is vertical and secure the base of
the flashing to the roof with roofing rails, slide
storm collar over the pipe section and seal with
a mastic.
9) Install the vertical termination cap by twist locking
it.
Notes:
a) For multistory vertical installations, a Ceil-
ing Fire stop is required at the second oor,
and any subsequent oor. Diagram 12. The
opening should be framed to 10 " x 10" inside
dimensions, in the same manner as shown
in diagram 9.
b) Any occupied areas above the rst oor,
including closets and storage spaces,
through which the vertical vent passes, must
be enclosed.
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" 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.
Slope "X"
0/12 - 2/12 4"
2/12 - 7/12 5-1/2"
7/12 - 12/12 6-3/4"

24/12+ 12-1/2"
Since some municipalities have additional local
codes it is always best to consult with your local au-
thorities and the CAN/CGA B149 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.
IMPORTANT: ALWAYS CHECK FOR
GAS LEAKS WITH A SOAP AND WATER
SOLUTION OR GAS LEAK DETECTOR.
DO NOT USE OPEN FLAME FOR LEAK
TESTING.
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 pres-
sures 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.
