4.10 Top Vent Connection, Horizontal Rear Termination
See figure 12.
Can be used with either #551DVK standard vent kit or another terminal cap
and accessories.
Adapter #817VAK, one 90° vent elbow and pipe lengths will be required.
(See venting options section of this manual).
The location requirements are shown in the table and graph below and
figure 12.

For installations with a horizontal rear termination, the combination
of horizontal and vertical vent pipes must be within the allowed area
shown in Graph 2. A minimum vertical pipe run of 6” is necessary.
Example a: If a vertical rise of 2ft 6” is required, the horizontal run
must not be more than 8ft”.
Example b: If a horizontal run of 3ft 6” is required, the vertical run
must be at least 1ft 3”.
The horizontal vent pipe run may be redirected by using
elbows up to a total of 180º but the maximum horizontal
run (E in figure 5 & graph 1) is reduced by 18” for every
45º. For example if two 90º elbows are used as in figure
13 the maximum horizontal run is reduced by 3ft per
elbow –
Total reduction = 6ft.
