pipe to the flue termination, slide the Wall
Thimble (Part # 942) over the flue pipe.
8) Slide the appliance and flue assembly
towards the wall carefully inserting the flue
pipe into the flue cap assembly. It is important
that the flue pipe extends into the flue cap
sufficient distance so as to result in a mini-
mum pipe overlap of 1-1/4 inches. Secure
the connection between the flue pipe and
the flue cap by attaching the two sheet metal
strips extending from the flue cap assembly
into the outer wall of the flue pipe. Use the
two sheet metal screws provided to connect
the strips to the pipe section. See Diagram
4.
9) Install wall thimble in the center of the 10"
square and attach with wood screws (Dia-
gram 5).

1) Maintain the 1-1/4" clearances (air
spaces) to combustibles when pass-
ing through ceilings, walls, roofs,
enclosures, attic rafter, or other
nearby combustible surfaces. Do
not pack air spaces with insulation.
Check pages 17-19 for the maximum
vertical rise of the flueing system
and the maximum horizontal offset
limitations.
2) Set the gas appliance in
its desired location. Drop
a plumb bob down from the
ceiling to the position of the
appliance flue exit, and
mark the location where
the flue will penetrate the
ceiling. Drill a small hole at his point. Next,
drop a plumb bob from the roof to the hole
previously drilled in the ceiling, and mark the
spot where the flue will penetrate the roof.
Determine if ceiling joists, roof rafters or
other framing will obstruct the flueing system.
You may wish to relocate the appliance or to

in a flat ceiling or wall, cut a 10 inch square
hole. Frame the hole as shown in Diagram
3 and install the firestop.
4) Assemble the desired lengths of pipe and

elbows. Ensure that all pipes and elbow
connections are in the fully twist-locked
position and sealed.
5) Cut a hole in the roof centered on the small
drilled hole placed in the roof in Step 2. The
hole should be of sufficient size to meet
the minimum requirements for clearance
to combustibles of 1-1/4". Slip the flashing
under the shingles (shingles should overlap
half the flashing) as per Diagram 4.
6) Continue to assemble pipe lengths.

Diagram 4: The upper half of the flashing is
installed under the roofing material and not
nailed down until the chimney is installed. This
allows for small adjustments.
Note: If an offset is necessary in the attic
to avoid obstructions, it is important
to support the flue pipe every 3 feet,

to avoid excessive stress on the el-
bows, and possible separation. Wall
straps are available for this purpose
(Diagram 2).
Galvanized pipe is desirable above the roof-
line due to its higher corrosion resistance.
Continue to add pipe sections through the
flashing until the height of the flue cap meets
the minimum height requirements specified
in Diagram 5 or local codes. Note that for
steep roof pitches, the vertical height must
