4. Venting installation
4.1 General
Select horizontal or vertical. Determine Path and Exit Location
4.1.1 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.
EXAMPLE A:
If the vertical dimension from the floor of the fireplace
to the center of the termination 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
to the center of termination is 24 feet, the horizontal
run to the outer wall flange must not exceed 10 feet.
EXAMPLE C:
If the horizontal run to the outer wall flange is 17 feet,
the vertical dimension from the floor of the fireplace
to the center of the termination must not be less than
7 feet 6 inches.
SPECIAL NOTE: For each 45° elbow installed in the
horizontal run, the length of the horizontal run MUST
be reduced by 18 inches. Reduce by 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.
