L52DF* Indoor Gas Fireplace
Installation
Example 2:
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 12 and 13).
"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. Flex runs over 3 feet must fall within the
limits set by the venting graph, and must have a minimum vertical rise
of 3" per foot of flex.
