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.

F39 Room Sealed Freestanding Gas Stove
1) Situate the chimney in a convenient loca-
tion 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.
Slope
0/12 - 2/12
2/12 - 7/12
7/12 - 12/12
12/12 - 24/12
24/12+
Using a level, make sure the support is
vertical. If the support extends above the
roof, cut it fl ush 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 fi nd it diffi cult to screw it
in place because it is fairly small
inside.
Simpson Dura-Flue 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 fi t under a fl ashing). Place the Finish
Collar around the support and fasten it to
the ceiling using the screws provided.
3) Use appropriate roof fl ashing. Place the
fl ashing under the upper shingles and on
top of the lower shingles approximately
half of the fl ashing should be under the
shingles.
4) Assemble the desired lengths of Black Pipe
and Elbows necessary to reach from the
appliance adaptor up through the support
box and fl ashing to proper height as per
Dia. 12, local codes or page 9. Ensure
that all pipe and elbow connections are in
their fully twist lock position.
5) Ensure fl ue is vertical and secure fl ashing
to the roof with roofi ng nails. Slide the
storm collar over the pipe section and seal
with a mastic.
INSTALLATION
6) Twist lock the fl ue cap on to the last sec-
tion.
Support Extensions - Round
(RDSE) or Square (SQSE)
Steep pitched cathedral ceilings may require
the use of a support extension. This piece fi ts
down inside the support and can be adjusted to
"X"
increase the support's length by up to 22". The
extension is attached to the support using the
4"
eight metal screws provided. Be sure there is
5-1/2"
at least a 2 inch overlap where the extension
joins the support.
6-3/4"
7-1/2"
12-1/2"
GAS CONNECTION
The gas connection is a 3/8" NPT 90
The gas line can be rigid pipe or to make in-
stallation easier, use a listed fl exible connector
and/or copper tubing if allowed by local codes.
Since some municipalities have additional
local codes it is always best to consult with
your local authorities and the CAN/CGA B149
installation codes.
When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
burner and/or valve servicing. Flare nuts for
copper lines and fl ex 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 fl ame for leak testing.
Note: Prior to any pressure testing of
the gas supply piping system that
exceeds test pressures of 3.45 kPa,
this appliance must be disconnected
from the piping system. If test pres-
sures equal to or less than 3.45 kPa
are used then this appliance must be
isolated from the piping system by
closing its individual manual shut-off
valve during the testing.
GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas sup-
ply piping system by closing its individual manual
shut-off valve during any pressure testing of the
gas supply piping system at test pressures equal
to or less than 3.45 kPa. Disconnect piping from
valve at pressures over 3.45 kPa.
The manifold pressure is controlled by a regu-
lator built into the gas control, and should be
checked at the pressure test point.
