Installation
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 66" and the horizontal run to
the wall flange of the vent termination is 60", this would be an acceptable
installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal run to
the wall flange of the vent termination is 172", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 60" and the
horizontal run to the wall flange of the vent termination is 144",
this would
NOT be an acceptable installation.
NOTES:
All dimension lengths for vertical or horizontal runs are
measured from centre of the vent pipe.
Venting runs
must
fall within the limits set by the venting
graph (see Figure 7).
Available Top Vent Components
The following venting components are available for he
HW42DF Top Vent.
Example 1:
For our shortest venting configuration use components A and E
(see
Figure 10)
.
Figure 10.
Typical Top Vent installation. If the 90° elbow is installed
directly on the fireplace, for height to the center of the
termination see chart on
page 3
.
Horizontal Venting
Figure 11.
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.

Termination
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
(see Figure 14)
. 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.
