RIGID PIPE VENTING
SYSTEMS
Horizontal or Vertical
Terminations
The Rigid Pipe Vent System offers a com-
plete line of component parts for installation
of both horizontal and vertical installations.
Many items are offered in decorative black,
as well as galvanized fi nish. We recommend
using the galvanized fi nish for installation
with the G33R-1.
The minimum components required for a basic
horizontal termination are:
1
AstroCap
Horizontal Termination Cap
1 90
o
Elbow
1 Rigid Pipe Adaptor
1 Wall Thimble
1 Length of pipe to suit wall thickness
(see
chart)
For siding other than vinyl furring strips may
be used, instead of the vinyl siding standoff,
to create a level surface to mount the vent
terminal. The Terminal must not be recessed
into siding.
If a Vinyl Siding Standoff is required (it must be
used with vinyl siding), measure to outside sur-
face of wall without siding and add 2 inches.
INSTALLATION
PROCEDURES
for UltraGlow Direct Vent
System (Flex)
1)
Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline of
the termination and mark wall accordingly.
Cut a 10"(254mm) hole in the wall (inside
dimension).
*
If this is an outside corner, the minimum distance
between the vent and the outside corner is 6"
(15cm) with
AstroCap
termination cap or 12"
(30cm) with Dura-Vent termination cap. See
"F" on the diagram on page 8.
Minimum and Maximum Vent Clearances
Note: A 1-1/2"(38mm) clearance around
the liner must be maintained except
that only a 1" (25mm) clearance is
needed at the termination end. We
recommend framing a 10"(254mm) x
10"(254mm) (inside dimensions) hole
to give structural rigidity for mounting
the termination.
Note: If installing termination on a siding
covered wall, furring strips must be
used to ensure that the termination
is not recessed into the siding.
2)
Level the fi replace and fasten it to the fram-
ing using nails or screws through the nailing
strips.
3)
Assemble the vent assembly by applying
Mill Pac to the 4"(100mm) inner collar of the
termination and slipping the 4"(100mm) liner
over it at least 1-3/8" (35mm). Fasten with
the 3 screws (drilling pilot holes will make this
easier). Apply Mill Pac or high temperature
silicone to the 6-7/8"(175mm) fl ex pipe and
slip it over the 6-7/8" outer collar of the vent
terminal at least 1-3/8"(35mm) and fasten
with the 3 screws.
4)
Separate the 2 halves of the wall thimble and
securely fasten the one with the tabs to the
outside wall making sure that the tabs are
on top and bottom. Fasten the other thimble
half to the inside wall. The thimble halves
slip inside each other and can be adjusted
for 2 x 4 or 2 x 6 walls.
The liners must slip
over the collars a minimum of 1-3/8".
5)
Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
Note: To make the installation more
aesthetically pleasing,
we recommend framing
out a square to mount
the terminal to.
INSTALLATION
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.
6)
Pull the centre 4"(100mm) liner and outer
6-7/8"(175mm) liner out enough to slip over
the fl ue collars of the fi replace.
7)
Apply Mill Pac over the fi replace inner collar
and slip the 4"(100mm) liner down over it
and attach with 3 supplied screws.
8)
Do the same with the 6-7/8"(175mm) liner.
9)
Apply a bead of silicone between the thimble
and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.
IMPORTANT: Do not locate termination hood
where excessive snow or ice buildup may
occur. Be sure to check vent termination
area after snow falls, and clear to prevent
accidental blockage of venting system. When
using snow blowers, make sure snow is not
directed towards vent termination area.
