UNIT INSTALLATION
WITH VERTICAL
TERMINATION
4" X 6-5/8" VENTING
(Rigid Vent Systems)
(
MUST USE REDUCER
#946-606 AND RIGID PIPE ADAPTOR
#770-994)
1) Maintain the 1-1/2" clearances
(air spaces) to combustibles
when passing through ceilings,
walls, roofs, enclosures,
attic rafter, or other nearby
combustible surfaces. Do not
pack air spaces with insulation.
Check "Venting" Sections for
the maximum vertical rise of
the venting 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 fl ue exit, and mark the
location where the vent will penetrate the
ceiling. Drill a small hole at this point. Next,
drop a plumb bob from the roof to the hole
previously drilled in the ceiling, and mark
the spot where the vent will penetrate the
roof.
3) A Firestop spacer must be installed in the
fl oor or ceiling of every level. To install the
Firestop spacer in a fl at ceiling or wall, cut
a 10 inch square hole. Frame the hole as
shown in Diagram 2 and install the fi restop.
Note: All vertical terminations are
vented using 4" x 6-5/8" venting and
reducer #946-606 and rigid pipe
adaptor #770-994.

4) Assemble the desired lengths of pipe and
elbows. Ensure that all pipes and elbow con-
nections are in the fully twist-locked position
and sealed.
NOTE: For best results and optimum perform-
ance with each approved venting system, it
is highly recommended to apply "Mill-Pac"
sealant (supplied) to every inner pipe connec-
tion. Failure to do so may result in drafting
or performance issues not covered under
warranty. Silicone (red RTV) is optional.
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 suffi cient size to meet
the minimum requirements for clearance
to combustibles of 1-1/2". Slip the fl ashing
under the shingles (shingles should overlap
half the fl ashing) as per Diagram 3.
Diagram 1
Diagram 3: The upper half of the fl ashing is
installed under the roofi ng material and not
nailed down until the chimney is installed. This
allows for small adjustments.
6) Continue to assemble pipe lengths.
Note: If an offset is necessary in the attic to
avoid obstructions, it is important to
support the vent pipe every 3 feet, to
avoid excessive stress on the elbows,
and possible separation. Wall straps
are available for this purpose.
Galvanized pipe is desirable above the roofl ine
due to its higher corrosion resistance. Continue
to add pipe sections through the fl ashing until
the height of the vent cap meets the minimum
height requirements specifi ed in Dia. 4 or local
codes. Note that for steep roof pitches, the
vertical height must be increased. A poor
draft, or down drafting can result from high
wind conditions near big trees or adjoining
roof lines, in these cases, increasing the
vent height may solve the problem.
7) Ensure vent is vertical and secure the base

of the fl ashing to the roof with roofi ng rails,
slide storm collar over the pipe section and
seal with a mastic.
8) Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces, which
the vent passes through must be
enclosed.
GAS LINE
INSTALLATION
The gas line is brought through the right side of
the appliance. The gas valve is situated on the
right hand side of the unit and the gas inlet is
on the right hand side of the valve.
The gas line connection may be made of rigid
pipe, copper pipe or an approved fl ex connector.
(If you are using rigid pipe, ensure that the valve
can be removed for servicing.) Since some
municipalities have additional local codes it is
always best to consult with your local authorities
and the CAN/CGA B149 installation code.
For USA installations follow local codes and/
or the current National Fuel Gas Code, ANSI
Z223.1.
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
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.
