flex venting. Use the vent graph to determine your
allowable run, then select appropriate components.

Example 1:
For our shortest venting configuration use components A and F (see
Figure 9a). This configuration is suitable for installations where the
fireplace backs directly against 4" stud wall. For deeper walls, use an
MEL-90FM elbow and an EXT-18 extension, which can be cut to the
required length.
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 (MIHR-10) used in conjunction with 3 ft. flex
section (MFL-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 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).
