VENTING FIREPLACE - REAR

To Use the Vent Graph (Figure 29)		Venting Graph (Dimensions in Feet)
1. Determine the height of the center of the		REAR EXIT - VERTICAL AND HORIZONTAL TERMINATION
horizontal vent pipe. Using this dimension on
		(DIMENSIONS IN FEET)
the Sidewall Vent Graph, locate the point it
		40
intersects with the slanted graph line.		39
2. From the point of this intersection, draw a vertical
		38
line to the bottom of the graph.
		37
3. Select the indicated dimension, and position the
unit in accordance with same.		36
EXAMPLE A:		35
If the vertical dimension from the floor of the unit		34
is 12 feet, 4 inches the horizontal run to the outer		33
wall flange must not exceed 12 feet, 3 inches.		32
EXAMPLE B:		31
If the vertical dimension from the floor of the unit is		30
6 feet, 9 inches the horizontal run to the outer wall		29
flange must not exceed 6 feet, 6 inches.		28
Special Note: For each 45 degree elbow installed		27
in the horizontal run, the length of the horizontal		26
run MUST be reduced by 18" (45cm). This does
not apply if the 45 degree elbows are installed on
the vertical part of the vent system. Reduce 3' for
every 90° elbow.
Example: According to the chart the maximum
horizontal vent length is 20' and if two 45 degree
elbows are required in the horizontal vent it must
be reduced to 17'.
The maximum number of 45 degree elbows
permitted per side wall installation is two (2).
These elbows can be installed in either the vertical
or horizontal run.
