45° or less Corner Installation. (Only available using Top Vent.)
Use a PTO-3 termination and an PFL-1 or PFL-2 (12" or 24"
compressed length) and a frame, if appropriate. Flex may be turned to
obtain desired degree of angle required but must not exceed 45°.

Figure 13. 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 3:
Rigid sections and an 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 7'6" when retracted in opposite direction
(see Figure 14 and 15).
"C" flex sections and "D" rigid sections may be used in conjunction with
one another to obtain different possible horizontal length installations.
NOTE: Flex section with no vertical rise must not exceed maximum
horizontal length of 3 feet (see Figure 14). Flex runs over 6' feet must
fall within the limits set by the venting graph, and must have a minimum
vertical rise of 3" per foot of flex.
