Temco DV1000/1200/1400DSN/DSP Series

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
beyond the brick surface. If the BEF extension is used,
measure to the outside surface of the framed wall and
add 4 additional inches to the venting length.

Flex Vent Offsets

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 ft. (305mm)
for every 45° bend and/or 2' (610mm) for each 90°
bend.
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)

NOTE: Typical terminal height "B" is 48" for model
DV1000, 60" for models DV1200 and DV1400 with
dimension "A" up to 36". Please refer to minimum
framing dimensions with horizontal venting chart on

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.
