Example 1:
For our shortest venting configuration use components A
and F
(see Figure 9a) .
Figure 9a. Typical Top Vent installation. If the 90° elbow is installed
directly on the fireplace, the height to the center of the
termination is 44".
Horizontal Venting
Figure 9b. Typical Top Vent installation. The solid sections can be
used in various combinations to obtain the desired vent
run. The vent run must fall within the limits set by the
venting graph.

Example 2:
A 10' section and elbow used in conjunction with 3 ft. flex section (PFL-
3) will, when extended in a five foot chase, allow for a maximum
horizontal run of twelve and one-half feet from the centre of the
fireplace to outside wall and a minimum of 8' when retracted in opposite
direction (see Figure 10 and 11).
"D" flex sections and "E" solid sections may be used in conjunction with
one another to obtain different possible horizontal length installations.
NOTE: Flex section must not exceed maximum horizontal length of 3
feet. (see Figure 12).
