Table 8 - Vent Section Length
INNOVATIVE HEARTH PRODUCTS • POWER VENT DV GAS FIREPLACES (DRT63__TYN / DRC63__TYN) • INSTALLATION INSTRUCTIONS
VENT SECTION LENGThS
Determine the number of straight vent sections
required. 4-1/2" (114 mm), 10-1/2" (267 mm),
22-1/2" (572 mm), 34-1/2". (876 mm) and 46-
1/2" (1181 mm) net section lengths are available
(see
Tables 7 and 8).
Offset Installation
Analyze the vent routing and determine the
quantities of vent sections and number of
elbows required. Refer to Figures 16 and 17
on Page 15
showing vent run requirements to
aid in selecting the type of vertical installation
desired. Vent sections are available in net lengths
of 4-
1/2" (114
mm), 10
-
1/2" (267
mm), 22
-
1/2"
(572
mm), 34
-
1/2" (876
mm) and 46
-
1/2" (1181
mm). Refer to the Vent Section Length Chart
for
an aid in selecting length combinations. Elbows
are available in 90° and 45° configurations. Refer
to Figure 15 on Page 14
for the SV4.5 E45 and
SV4.5 E90 elbow dimensional specifications.
Where required, a telescopic vent section
(SV4.5LA)
may be used to provide the installer
with an option in installing in tight and confined
spaces or where the vent run made up of fixed
length pieces develops a joint in a undesirable
location, or will not build up to the required
length. The SV4.5LA Telescopic Vent Section
has an effective length of from 1-1/2" (38
mm)
to 6-
3/4" (171
mm). The SV4.5LA is fitted with a
dimpled end (identical to a normal vent section
component) and a plain end with 3 pilot holes.
Slip the dimpled end over the locking channel
end of a standard SV4.5 vent component the
required distance and secure with three screws.
Maintain a minimum 1" (25 mm) clearance
to combustible materials for all vertical ele-
ments. Clearances for all horizontal elements
are 3" (76 mm) on top, 1" (25 mm) on sides
and 1" (25 mm) on the bottom.
