installation
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 lock-
ing.
Notes:
a) For multistory vertical installations, a Ceil-
ing Fire stop is required at the second floor,
and any subsequent floor. 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 first floor,
including closets and storage volcanicces,
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 vol-
canicce 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- 1/2"
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 vertical.
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 sup-
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 Col-
lar 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 support
box and flashing to proper height as per
Diagram 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.

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 1/2" MIP x 24" long flex-
ible connector. 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.
port you may find it difficult to
screw it in place because it is
fairly small inside.
Since some municipalities have additional local
codes it is always best to consult with your local
authorities 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 ap-
pliance 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.
