QUALIFIED INSTALLERS ONLY
Figure 4. Possible Vent Congurations; Vertical and
Horizontal Terminations.
VENT CONFIGURATIONS:
Figures 4 shows the range of venting options, it shows
possible vent congurations if the unit is top vented,
for vertical and horizontal terminations, any layout that
remains within the shaded area is acceptable. Having the
fewest number of elbows is ideal, as they tend to disrupt
air movement. Using 45˚ elbows is preferable to using 90˚
elbows. Also, a shorter vent system will perform better than
a longer one.
NOTE: The total length of the vent pipes can not exceed
33 feet (10.1 m). Any combination of rise and run can be
used as long as it lays within the shaded area (a total of
three (3) 90° elbows or six (6) 45° elbows can be used).
In addition to what is shown, if a 90° elbow is used in the
horizontal plane, 3 feet (91.4 cm) must be subtracted from
the allowable horizontal run (for each 45° elbow, 1 feet
must be subtracted from the allowable horizontal run).
VENT RESTRICTOR RING:
A vent restrictor ring is supplied with each direct vent replace. This
restrictor ring is to be installed when the vertical chimney installation
is over 15 feet (4.57 m). Before the chimney is placed onto the stove,
place this vent restrictor ring into the 4 inch (10.2 cm) ue pipe (as
shown), once the vent restrictor ring has been installed, the vertical
sections of chimney can be installed.
