Sidewall (Horizontal) Venting; Flex Vent Offsets - Temco DV1000MBN Homeowner's Installation And Operating Manual

Temco DV1000/1200/1400MBN Series
•
For 4" x 7" flex, the 7" flex has an outside diameter
of 7 " (191mm) and if installed in a chase the
inside diameter of the chase should be 9 "
(241mm) minimum.
•
Lengths of co-axial flex may be joined together
using a flex connector kit (GFPVCK) only, maximum
1 kit per installation.
An extension collar is included with side wall cap kits
to simplify the connection of the flex pipe to the fire-
place. Refer to Page 13, Figure 22.
ATTENTION: Spacer springs must be installed when
installing flexible venting systems.
Wrap spacer spring around flex flue pipe and overlap
spring ends approximately 2" (610mm). Tie one end
over the other like a shoelace tie, then reverse direc-
tion of spring ends. Lift up hooped spring and slide
both spring ends underneath hooped spring. Spring
spacers should be spaced at approximately 12"
(305mm) intervals for the length of pipe system. Once
the springs are placed around the flue pipe, slide the
flue section with spacer springs into the outer flex pipe.

ping ends.
CAUTION: Care must be taken when
tightening clamps so the flex does not
tear at clamp location.

Sidewall (Horizontal) Venting

For side wall (Horizontal) venting, this appliance is
approved for use with a 7" x 4" flexible venting system
with spacers.
Clearance to combustible material from the pipe is 1"
(25mm). Sides and bottom, 2" clearance from the top.
Note: O.D. of pipe is 7 " (191mm).

Horizontal Vent Kits
♦ CDV-HSK (Round Termination Cap)
The vent starter kit contains the following:
• Horizontal termination
• Wall thimble
•
36" of 7" x 4" flex with spacers and clamps.
•
Extension collar
♦ HFTK (Trapezoid Termination Cap)
The vent starter kit contains the following:
•
Horizontal termination
•
Wall thimble
•
Extension collar
NOTE: HIGH WIND AREAS All termination caps are
tested and certified for wind conditions up to 40 mph
(64 k/h).
A Vinyl Extension Frame Kit No. VEF is required for all
installations where vinyl siding is used with the HFTK
Kit or HSQ47 Horizontal Vent Termination. If a Vinyl
Extension Frame Kit No. VEF is used, measure to
outside surface of wall without siding and add 2 addi-
tional inches (51mm) to the venting length.
A brick extension kit No. BEF is available to extend the
horizontal vent terminal HSQ47 or HFTK kit terminal
Spacer
beyond the brick surface. If the BEF extension is used,
Springs
measure to the outside surface of the framed wall and
add 4 additional inches to the venting length.
Each installation assumes the use of (1) 45° (bend)
starting off top of unit.
To determine the amount or length of flex vent you
need for a given installation, add the total offset dimen-
sion to the total rise needed. Then add 1' (305mm) for
every 45° bend and/or 2' (610mm) for each 90° bend.
Flex Flue
No more than (4) 90° and (2) 45° offsets are to be used
per installation. Vent terminal cap location should be in
accordance with the Venting Graph chart and the
Vertical Termination Location information.
1. Measure the total wall thickness. Determine whether
or not the thimble extension is needed. If the com-
bustible wall depth is over 5" (127mm), the exten-
sion should be used. (Fig. 19)
2. Assemble wall thimble with thimble extension flange
to top. Mate thimble to wall plate with the four tabs
provided. Bend tabs over to secure. (Fig. 19)
3. Install the wall thimble assembly through the framed
opening so the firestop plate is on the interior wall.
(Fig. 20) Telescope section should extend all the
way through wall.
4. Step 1: Apply Mill-Pac to 4" flue inner pipe on cap.
Step 2: Connect 4" flex flue to flue on cap with
band clamp.
