TOP VENT SYSTEM IDENTIFICATION

Begin the vent system installation by selecting the type of venting
to be installed and the path that it will take. Verify that clearances
are met throughout the path of the venting system.
Determine how the vent system will be terminated out the
side of the house or through the roof. Verify clearances for the
termination.

VENT SYSTEMS

Use one of the following 5 x 8 vent systems:
Simpson Duravent® GS
American Metal Products
Selkirk Direct-Temp®
ICC
Security Secure Vent
Simpson Duravent - DVA-H2
Empire Flex Vent Kit - DVVK-5F
Page 26
When selecting a vent system for use with the fireplace, refer
to the "Venting Fireplace" section in this manual to determine
what systems are acceptable. Check all clearances and venting
components. Identify problems existing in the vent system, if
any. Use pages 27 to 34 for venting to eliminate issues after
installation. Check pipe diameter on vent system and fireplace to
verify the size is the same.
NOTICE: All outer connection joints must be sealed with
aluminum tape, screws or silicone sealant rated above
300°F/149°C. The inner flue joints do not require any sealant.

VENTING GRAPH

NOTICE: The initial 45° elbow is considered to be part of the
fireplace and does not factor in the venting calculations.
To Use the Vent Graph
1. Determine the height of the center of the horizontal vent
pipe. Using this dimension on the Sidewall Vent Graph,
locate the point it intersects with the slanted graph line.
2. From the point of this intersection, draw a vertical line to the
bottom of the graph.
3. Select the indicated dimension, and position the fireplace in
accordance with same.

HORIZONTAL RUN
Figure 41

EXAMPLE A:
If the vertical dimension from the floor of the fireplace is 32 feet,
the horizontal run to the outer wall flange must not exceed 5 feet.
EXAMPLE B:
If the vertical dimension from the floor of the fireplace is 24 feet,
the horizontal run to the outer wall flange must not exceed 10
feet.
EXAMPLE C:
If the vertical dimension from the floor of the fireplace is 7 feet,
the horizontal run to the outer wall flange must not exceed 15
feet.
SPECIAL NOTICE: For each 45° elbow installed in the horizontal
run, the length of the horizontal run MUST be reduced by
18 inches. Reduce 3 feet for every 90° elbow. This does not
apply if the 45° elbows are installed on the vertical part of the
vent system.
Example: According to the chart the maximum horizontal
vent length is 20 feet and if two 45° elbows are required in the
horizontal vent it must be reduced to 17 feet.
The maximum number of 45° elbows permitted per side wall
installation is two. These elbows can be installed in either the
vertical or horizontal run.
The maximum number of 90° elbows in a vent run is three.
NOTICE: When figuring horizontal run length, the first elbow
does not get counted. This is not referring to the initial 45° elbow
which is considered to be part of the fireplace.
NOTICE: A horizontal vent with the minimum required vertical
rise (using a 12 inch section of vent before the elbow) will use
a maximum of a 9 inch section of horizontal vent before the
termination.
Acceptable vertical and horizontal vent run.
(40ft maximum vertical and 20ft maximum horizontal)
Unacceptable vertical and horizontal vent run.
