Special Vent Systems
The following vent systems are acceptable for use with the
DVP30CA fireplace:
Simpson Duravent® GS 4" - 6 5/8"
*American Metal® 4" - 6 5/8"
*Selkirk Direct-Temp® 4" - 6 5/8"
* American Metal® and Selkirk Direct-Temp® CAN NOT be
used in side wall horizontal vent installations in the state of
Massachusetts.
56 1/4”
(1.43 m)
90° ELBOW
24” PIPE SECTION
(610 mm)
Venting graph (Dimensions in Feet) (Figure 6)
1. Determine the height of the center of the termination. Using this
dimension on the Venting Graph, locate the point it intersects
with the slanted graph line, or the right edge of the graph.
2. From the point of this intersection, draw a vertical line to the
bottom of the graph.
3. Adjust the indicated maximum dimension for additional elbows
if necessary.
4. Position the unit so that maximum horizontal run is not
exceeded.
Venting Requirements (Figure 6)
Minimum vertical rise from appliance outlet before any elbows =
24 inches (610 mm).
Maximum vertical rise from appliance outlet = 25 feet (7.62 m), the
restrictor plate must be used above 10 feet.
Maximum horizontal run from appliance outlet = 12 feet (3.66 m).
Maximum vertical rise and horizontal run is a combined total of 25
feet (7.62 m).
Maximum elbows = (2) 90°, for the second elbow subtract 5 feet
from a horizontal run.
To Use the Vent graph
EXAMPLE A:
If the vertical rise from the appliance outlet is 21 feet, the horizontal
run to the outer wall flange of the vent termination must not exceed
4 feet with (1) 90° elbow.
EXAMPLE B:
If the vertical rise from the appliance outlet is 14 feet, the horizontal
run to the outer wall flange of the vent termination must not exceed
11 feet with (1) 90° elbow.
SPECIAL NOTE:
For each 45 degree elbow installed in the horizontal
run, the length of the horizontal run MUST be reduced by 18 inches
(457.2 mm). This does not apply if the 45 degree elbows are installed
on the vertical rise of the vent system.
Example:
According to the chart the maximum horizontal run is 12
feet and if two 45 degree elbows are required in the horizontal run
it must be reduced to 9 feet.
The maximum number of 45 degree elbows permitted per side
wall installation is two. These elbows can be installed in either the
vertical rise or horizontal run.
